The steam blowing procedure in texas typically follows a series of well-defined steps, designed to ensure that the piping system is properly cleaned and prepared for use. Here is an overview of the procedure:

Preparation and Inspection Before starting the steam blowing process, it’s essential to prepare the system. Technicians inspect the piping network, ensuring there are no leaks or weaknesses. All valves, flanges, and connections are checked for proper sealing. The entire system is set up to withstand the high-pressure steam that will flow through it.

System Flushing In some cases, a flushing procedure may be carried out before steam is introduced. This step is particularly important if the piping system is new and may contain installation debris or if the pipes have not been cleaned in a while. Flushing is done with water to remove large particles and dirt.

Steam Injection High-pressure steam is then injected into the piping system. The steam is blown at a velocity that is capable of dislodging any remaining particles inside the pipes. This is the most critical step in the steam blowing procedure, as the high-pressure steam ensures the system is completely cleaned.

Monitoring and Observing During the steam blowing process, technicians monitor the system closely. They track the steam flow, pressure, and any debris being ejected from the pipes. The goal is to ensure that all contaminants have been effectively removed.

Post-Blowing Inspection After the steam blowing process is complete, a final inspection is conducted to verify that the system is free of contaminants and fully operational. The pipes are checked for leaks, and the equipment is tested to ensure it is functioning correctly.

System Shutdown and Cleaning Once the steam blowing procedure is completed, the system is allowed to cool down, and any remaining water is removed. The pipes are thoroughly cleaned and dried, making sure they are ready for normal operation.

Conclusion

Steam blow services are a crucial part of maintaining the efficiency and longevity of steam systems in Texas. By following a meticulous procedure, industrial plants can ensure that their equipment runs smoothly, avoiding downtime and costly repairs. Whether it’s a newly installed system or one that’s been in service for years, a proper steam blow procedure is vital to ensure the highest performance standards are met.

VARTECH TECHNOLOGY:  AN UNBELIEVABLY EASY METHOD THAT WORKS FOR YOUR GAS TURBINE

To understand how VARTECH Technology can work incredibly well for your Gas Turbine, it is important to understand varnish and the problem it creates.

Varnish is a broad term covering various kinds of deposits in oil systems. Some types are rigid and firm, others sticky, and others are commonly referred to as sludge. However, the common factor is that they typically begin from the degradation of the oil in the system.

Varnish usually forms and sticks in areas that are extremely hot or very cool and sluggish.

Now, measuring or finding varnish is an enormous challenge since varnish does not turn up in the oil, but on the metal surfaces. The only way to identify varnish is to see it on a surface or to experience its effect. For example, a sticky valve is an apt indicator of the presence of varnish.

It is triggered in many ways. The cycle of varnish begins with something that upsets the lubricant’s stability, such as excessive heat. This can lead to the degradation of the oil, resulting in the formation of impurities. For a while, these impurities often remain dissolved in the oil, causing no harm. But, as more and more accrue, however, they stick together, forming insoluble, suspended submicron particles and once they stick to metal surfaces, they become varnish.

Varnish accumulation reduces a lubricant’s heat transfer properties and causes your system to run hotter and hotter. The consequences won’t just jeopardise your equipment — it will cause de-rated equipment, unpredicted shutdowns, inefficient operation, enhanced maintenance labor management, and spending, higher costs, and lost profits for the owner.

In some turbines, varnish focuses on servo valves, causing them to stick and either delay movement or refuse to move, which can send the turbine out of operation, causing a complete shutdown. In a peaking turbine, one that is held in reserve for peak demand, stuck servo valves can lead to failure to start. Downtime and repair costs can run anywhere from $100,000 into the millions.

Varnish buildup in gas turbines is a big concern for our industrial lubricant customers. While some cleaners in the market are effective in certain circumstances, they may also present several issues. But, VARTECH Technology has addressed the issues of greatest concern, namely water separability; oxidation stability; and seal compatibility.

Residual dispersal/detergent cleaner remaining in the oil system when the oil is changed can ruin the fresh oil that is installed. To ensure that the cleaner is expunged from the system, a full flush is required.

This is where VARTECH™ Industrial System Cleaner (ISC), can come into play. A non-solvent-based solution that can be added straight to oil during operation, VARTECH technology cleans varnish and sludge from the system before a regular oil change. In exhaustive lab testing against existing products, Chevron VARTECH™ ISC showed very good seal compatibility, water/oil separability, and oxidation performance.

To understand how VARTECH Technology can be an incredibly easy method that works for your gas turbine, we can take a case in point of offshore production platforms with three turbines on board. The turbine in question had a severe varnish issue and the oil cooler had been contaminated, rendering the temperature rise to where the operators would have to shut the turbine down to replace the cooler.

VARTECH ISC was added and over one hour, the main oil header temperature dropped around 10 degrees, from too high to normal. The product had an immediate effect on the operating conditions of the oil cooler. In comparison, when the previous dispersant/ detergent product was used, it took two days to see a temperature drop.

That product was also blocking the filters in the system frequently with varnish debris. VARTECH ISC had no such filter plugging effect over the two-day test period. Subsequent testing continued, it revealed that VARTECH ISC outperformed many other commonly used cleaners in cleaning efficiency, effectiveness, and system compatibility without drastically affecting water separability and oxidation stability. This compatibility also reduces the performance impact for the fresh oil when flushing is unfeasible, and it does not need to be used in combination with a varnish filtration system. It is not recommended not to leave any varnish cleaner in a system indefinitely. Simply add VARTECH ISC before a scheduled oil change, and the removed varnish debris will come out with the old oil.

Unveiling the Power: Exploring the Importance of Transformer Oil Testing

Introduction

Importance of Oil Testing in Transformers

Oil testing serves as a diagnostic tool to evaluate the condition of the insulating oil used in transformers. By analyzing the oil’s composition and properties, experts can detect potential issues such as contamination, oxidation, or degradation. This enables early detection of problems, facilitating timely preventive maintenance or repairs.

Regular oil testing provides multiple advantages:Early Problem Detection:It helps identify abnormal conditions that might otherwise go unnoticed, reducing the risk of unexpected failures and costly downtime.Enhanced Decision-Making: It offers valuable insights into the overall health of the transformer, aiding in informed decision-making regarding maintenance and replacement strategies.

In conclusion, oil testing is an indispensable practice for ensuring the reliability and longevity of transformers. By leveraging oil analysis, companies can proactively address potential problems, optimize performance, and ultimately save significant costs in the long run.

Why is Oil Testing Important for Transformers?

Transformers are the backbone of modern electrical power systems, playing a crucial role in the efficient transmission and distribution of electricity. These vital components rely on insulating oil to maintain performance and longevity. The insulating oil not only acts as an electrical insulator but also helps dissipate heat generated during the transformer's operation. Over time, this oil can become contaminated, oxidized, or degraded, leading to issues that compromise the transformer’s functionality and may result in catastrophic failures.

Oil testing provides a comprehensive evaluation of the oil's condition, allowing for the early detection of potential issues. By analyzing the oil’s physical, chemical, and electrical properties, experts can identify abnormalities or changes that may indicate underlying problems within the transformer. This proactive approach enables timely preventive maintenance, repairs, or replacements, ultimately enhancing the transformer’s reliability and extending its service life.

Furthermore, oil testing is a critical component of a transformer’s health monitoring and maintenance program. By regularly assessing the oil’s condition, operators can make informed decisions about the transformer’s operational status and maintenance requirements. This helps minimize the risk of unexpected failures and ensures the reliable delivery of electricity to end-users.

Types of Tests Conducted in Oil Testing

Physical Tests:Focus on the oil’s physical characteristics, such as color, appearance, viscosity, and dielectric strength. These parameters can indicate contamination, oxidation, or degradation of the oil.

Chemical Tests:Chemical analysis provides insights into the oil’s composition and the presence of contaminants or byproducts. Tests such as dissolved gas analysis (DGA), acid number measurement, and water content determination can help identify issues like overheating, partial discharges, or moisture presence.

Electrical Tests:Evaluate the oil’s electrical properties, such as dielectric breakdown voltage, power factor, and resistivity. These tests determine the oil’s ability to withstand electrical stress and provide early warning signs of potential insulation failures.

Understanding BDV Testing

The BDV test uses a specialized apparatus that gradually increases the voltage applied to the oil sample until breakdown occurs. A low BDV value indicates reduced insulating capacity due to contamination or deterioration. Regular BDV testing ensures that the oil maintains its dielectric strength, allowing the transformer to operate safely under various electrical loads. Maintaining a high BDV value allows transformers to operate more reliably and efficiently, minimizing the risk of insulation failure and unexpected downtime. As part of a comprehensive oil testing program, BDV testing provides a clear indication of the oil’s health and supports informed maintenance decisions.

Benefits of Regular Oil Testing

Regular oil testing offers a multitude of benefits for transformer owners and operators, making it an essential component of a comprehensive asset management strategy:

Early Problem Detection:Regular monitoring allows for early identification of potential issues like contamination, oxidation, or degradation, enabling timely preventive maintenance or corrective actions.

Optimization of Maintenance Strategies:Oil testing provides data that can be used to optimize the transformer’s maintenance schedule, ensuring efficient resource allocation and peak performance.

Improved Reliability and Lifespan:Addressing issues identified through oil testing helps extend the equipment’s lifespan and enhance its overall reliability, reducing the need for costly replacements.

Cost Savings:Regular oil testing can lead to significant cost savings by proactively addressing problems before they escalate, avoiding high expenses associated with emergency repairs, unplanned downtime, and premature equipment replacement.

Common Issues Detected Through Oil Testing

Oil testing is a powerful tool for identifying a wide range of issues that can affect the performance and longevity of transformers. Some common problems detected through oil analysis include:

Contamination: Foreign particles, such as dirt, moisture, or metal particles, can compromise the oil’s insulating properties, leading to increased electrical stress.

Oxidation:Over time, insulating oil can oxidize, forming sludge, varnish, and other byproducts that impair cooling and insulating capabilities.

Thermal Degradation:Excessive heat can break down the oil, forming gases and byproducts that indicate overheating or insulation failure.

Partial Discharges: Localized electrical discharges can be detected through oil testing, indicating insulation issues or maintenance needs.

Frequency of Oil Testing

The frequency of oil testing depends on the transformer’s size, age, and operating conditions. For smaller transformers, testing may be conducted annually or every two years. However, for larger, more critical transformers, more frequent testing, semi-annually or quarterly is typically recommended. Factors such as operating environment, load conditions, and any known issues can also influence testing frequency. For example, transformers in harsh environments or under high-stress conditions may require more frequent testing to ensure reliable performance.

Oil Testing Methods and Equipment

Oil testing for transformers involves various analytical techniques and specialized equipment, including:

Dissolved Gas Analysis (DGA):Measures dissolved gas concentrations in the oil, providing insights into potential issues like overheating, partial discharges, or arcing.

Dielectric Breakdown Voltage Testing: Assesses the oil’s ability to withstand electrical stress, a key indicator of its insulating performance.

Interfacial Tension (IFT) Measurement:Evaluates the oil’s stability at the water interface, with changes indicating contamination or oxidation.

Fourier Transform Infrared (FTIR) Spectroscopy: Identifies the chemical composition of transformer oil, including the presence of additives, contaminants, and degradation by-products.

How to Interpret Oil Testing Results

Interpreting oil testing results is critical for understanding the transformer’s condition and determining appropriate actions. Experienced professionals evaluate various parameters, comparing them to industry standards and historical data to identify abnormalities or trends that may indicate underlying issues. For example, increased concentrations of dissolved gases like hydrogen or acetylene may suggest partial discharges or overheating. Similarly, a decrease in dielectric breakdown voltage or an increase in acid number may indicate the need for oil filtration or replacement. By taking a holistic approach to interpreting oil testing data, professionals provide informed recommendations for maintenance, repairs, or replacement, ensuring reliable transformer operation.

Importance of Professional Oil Testing Services

Entrusting oil testing to professional service providers ensures the accuracy and reliability of results, as well as the effective implementation of maintenance strategies. Professional services offered:

Accurate and Reliable Results:Calibrated equipment and strict quality control protocols ensure accurate and reliable oil testing results.

Comprehensive Analysis and Interpretation:In-depth analysis and interpretation of data, identifying potential issues, and recommending corrective actions.

Compliance with Industry Standards:Adherence to ASTM (American Society for Testing and Materials) standards ensures quality testing procedures and reporting.

Customized Maintenance Strategies:Tailored maintenance strategies based on the specific needs and conditions of the transformer.

Conclusion

In the world of electrical power systems, the importance of oil testing for transformers cannot be overstated. As the backbone of modern power grids, transformers play a crucial role in delivering reliable electricity. Oil testing provides invaluable insights into the condition of a transformer’s insulating oil, enabling early detection of potential issues and facilitating timely maintenance actions. The benefits of regular oil testing include improved reliability, extended lifespan, and significant cost savings. By embracing this essential practice, companies can unlock the power of their transformers, ensuring they remain resilient, efficient, and ready to meet the evolving energy needs of the future.

P.S :

NAS stands for ‘National Aerospace Standard of America’. It is the standard for oil cleanliness which indicates the number of microscopic particles of different size say 2-5, 5-15, 15-25, 25-50, 50-100 and above 100 micron present in 100 ml oil sample. In naked eye human can see only the macroscopic or large particles which is larger than 40-70 micron size. But the particle size below 40-70 micron which is called microscopic particles can not be seen without microscope. Whereas under normal circumstances thousands of such microscopic particles are always present in air, oils and containers. These particles creates lots of problems including damage of sophisticated hydraulic and turbine equipments specially servo valves.

Through ordinary filtration system in blending plants microscopic or humanly invisibleparticles can not be removed. In NAS filtration system a specially designed membrane filter is used where all microscopic particles ranging from 2 micron to above and even pathogenic bacteria which can not be seen in naked eye are removed.

Depending on the number of particles in different size present in 100 ml of oil there are following cleanliness levels called NAS values.

1. NAS 0

3. NAS 1 to 12

4. NAS-99

Ordinary or Raw Oils possess NAS Value 11-12. Standard NAS for oil is NAS 6 Special requirement for NAS is below 6 and the lower the batter because lower NAS value indicates the lower number of particles present in the oil. There are two systems of measuring NAS values. One is called “On-line” and another is called “Off-line”. In “On-line” measurement system NAS value is measured in operation site during filtration process is going on. On the other hand, in “Off-line” filtration system a sample is collected from the system and taken to the laboratory in a sample bottle and tested. Off-line is more erotic than On-line measurement because the probability of particle contamination is high in Off-line as particles may come from sample bottle or containers.

NAS ย่อมาจาก ‘National Aerospace Standard of America’ มันคือ มาตรฐานความสะอาดน้ำมันซึ่งระบุจำนวนของอนุภาคด้วยกล้องจุลทรรศน์ที่แตกต่างกัน ขนาดพูด 2-5, 5-15, 15-25, 25-50, 50-100 และสูงกว่า 100 ไมครอนนำเสนอในน้ำมัน 100 มล ตัวอย่าง. ในตาเปล่ามนุษย์สามารถมองเห็นได้ด้วยตาเปล่าหรืออนุภาคขนาดใหญ่ซึ่งก็คือ ขนาดใหญ่กว่า 40-70 ไมครอน แต่ขนาดของอนุภาคต่ำกว่า 40-70 ไมครอนซึ่งเรียกว่าไม่สามารถมองเห็นอนุภาคขนาดเล็กได้โดยไม่ใช้กล้องจุลทรรศน์ ในขณะที่อยู่ในสภาวะปกติ

สถานการณ์หลายพันอนุภาคขนาดเล็กเช่นนี้มักปรากฏอยู่ในอากาศน้ำมันและ ตู้คอนเทนเนอร์ อนุภาคเหล่านี้สร้างปัญหามากมายรวมถึงความเสียหายที่ซับซ้อน อุปกรณ์ไฮดรอลิกและกังหันพิเศษเซอร์โววาล์ว ผ่านระบบการกรองธรรมดาในการผสมพืชด้วยกล้องจุลทรรศน์หรือมองไม่เห็นมนุษย์ อนุภาคไม่สามารถกรองแยกคัดออกได้ ในระบบการกรอง NAS ใช้ตัวกรองเมมเบรนที่ออกแบบมาเป็นพิเศษในทุกที่ อนุภาคขนาดเล็กตั้งแต่ 2 ไมครอนขึ้นไปและแม้แต่แบคทีเรียที่ทำให้เกิดโรคซึ่ง

ไม่สามารถมองเห็นได้ด้วยตาเปล่าจะถูกกรองคัดออก ขึ้นอยู่กับจำนวนของอนุภาคที่มีขนาดแตกต่างกันในน้ำมัน 100 มล ตามระดับความสะอาดที่เรียกว่าค่า NAS

1. NAS 0

3. NAS 1 ถึง 12

4. NAS-99

น้ำมันธรรมดาหรือน้ำมันดิบมีค่า NAS 11-12 มาตรฐาน NAS สำหรับน้ำมันคือ NAS 6

ข้อกำหนดพิเศษสำหรับ NAS ต่ำกว่า 6 และยิ่งเศษผงแป้งน้อยลงเพราะค่า NAS ต่ำ ระบุจำนวนอนุภาคในน้ำมันที่ต่ำกว่า มีระบบการวัดค่า NAS สองระบบ หนึ่งเรียกว่า “ออนไลน์” และอื่น ๆ คือ เรียกว่า “ออฟไลน์” ในระบบการวัด “ออนไลน์” ค่า NAS ถูกวัดในพื้นที่ดำเนินการระหว่างการกรอง กระบวนการกำลังเกิดขึ้น ในทางตรงกันข้ามในระบบการกรองแบบ “ออฟไลน์” จะมีการเก็บตัวอย่างจากระบบ และนำไปที่ห้องปฏิบัติการในขวดตัวอย่างและทดสอบ การวัดแบบออฟไลน์มักมีค่ามากกว่าการวัดแบบออนไลน์เพราะความน่าจะเป็นของอนุภาค การปนเปื้อนอยู่ในระดับสูงเนื่องจากอนุภาคอาจมาจากขวดตัวอย่างหรือภาชนะบรรจุ

Most common level of NAS in new oil is 7-8. Oil companies will propably argue this and i would accept a NAS 6 if we are talking 1gallon plastic containers tapped on site. But in barrels and in bulk it will for obvious reasons be much higher (logistics chain and container type). It has become more and more common for the aware maintenance crew to do a filling through a filter. (hope they have a fixed filter on the system or it will be in vain, due to accumulated dirt in te tank)., because cleanliness levels should becompred to dynamic clearances in the system. Look at the clearances and then consider if an in-line 10micron filter will have much effect on wear… But ISO code Class is mentioned with only 2 numbers. This is normal for lubeoils (SAE grade engine oils) because sootparticles are so abundant. All other oiltypes should show 3 numbers (4406, 4,6,14micron ranges). if only two numbers are given it is the 4 micron range that is omitted, so you are looking at 6 and 14 micron numbers. Have a look at the dynamic clearances again an let me know if the analysis provides much useful info… On the topic of additives or the “removal” of same… Yes the filter often gets the blame. But dont blame the gun, blame the shooter. If a filter removed additives, it is because of other factors influencing the system. The filter does what it is inteded to do: keep the system clean and dry. The filter only removes particles within the rate/range of filtration given and as stated by most additives are soluble in the oil and most machinery manufacturers specify “all additives must be soluble”. One exemption though, Antifoam silicone can sometimes be inadequately distributed in the oil and appear as droplets larger than they should be. They will agglomerate if particles are present and if they are large enough, the filter removes the lot.Funny thing is, that if silicone agglomorates, they loose the AF capability. They still show up on the spectral analysis but they are not active. Hence the filter gets the blame, regardless if the AF capabilities are unchanged if you should compare the two oils (oil with effective filter vs.oil with no filter and high particle count). Simple solution, use acrylate as AF. But of course this shows on the pricetag. And please beware, in any case particles less than stated in the standard (NAS or ISO) will not be counted, regardless of how abundant they are represented. You can have a ok cleanliness on paper, but in real life the oil is pitch black, just tink of diesel engine oils. Also beware that a single analysis/particle count only represents a moment in time. “Will fine particle filters, in the range of 0.5 microns to 5.0 microns filter out the additives from lube oils ? Is it correct that most of these additives are soluble in oil and, those which are not, are of the sizes 0.05 microns or lesser ?

ระดับที่พบมากที่สุดของ NAS ในน้ำมันใหม่คือ 7-8 บริษัท น้ำมันจะเถียงอย่างนี้และจะรับ NAS 6 ถ้าเราพูดถึง 1gallon บรรจุภัณฑ์พลาสติก แต่ในถังและในจำนวนมากมันจะด้วยเหตุผลที่ชัดเจนจะสูงกว่ามาก (ห่วงโซ่โลจิสติกและประเภทภาชนะ) มันเป็นเรื่องธรรมดามากขึ้นสำหรับทีมงานซ่อมบำรุงที่รู้ตัวเพื่อทำการเติมผ่านตัวกรอง (หวังว่าพวกเขาจะมีตัวกรองคงที่ในระบบหรือมันจะไร้ประโยชน์เนื่องจากสิ่งสกปรกสะสมในถัง )

เนื่องจากระดับความสะอาดควรกลายเป็นระบบที่มีการกวาดล้างแบบไดนามิก ดูที่การพิจารณาว่าตัวกรอง 10 ไมครอน จะมีผลกระทบต่อการสึกหรอหรือไม่ … แต่รหัส ISO คลาสนั้นมีเพียง 2 หมายเลขเท่านั้น นี่เป็นเรื่องปกติสำหรับ lubeoils (น้ำมันเครื่องเกรด SAE) เพราะอนุภาคมีมากมาย สปีชีส์อื่นควรแสดง 3 หมายเลข (ช่วง 4406, 4,6,14 ไมครอน) ถ้าให้ตัวเลขสองตัวเท่านั้นมันคือช่วง 4 ไมครอนที่ถูกละไว้ดังนั้นคุณจะดูที่ 6 และ 14 ไมครอนตัวเลข มาดูการฝึกปรือแบบไดนามิกอีกครั้งและแจ้งให้เราทราบหากการวิเคราะห์ให้ข้อมูลที่มีประโยชน์มาก … ในหัวข้อของสารเติมแต่งหรือ “การลบ” ที่เหมือนกัน … ใช่ตัวกรองมักจะได้รับการตำหนิ แต่อย่าโทษว่าเป็นปืน หากตัวกรองลบสารเติมแต่งนั่นเป็นเพราะปัจจัยอื่น ๆ ที่มีอิทธิพลต่อระบบ ตัวกรองทำในสิ่งที่ต้องทำ: รักษาระบบให้สะอาดและแห้ง ตัวกรองจะกำจัดอนุภาคภายในอัตรา / ช่วงของการกรองที่ระบุและตามที่ระบุโดยสารเติมแต่งส่วนใหญ่จะละลายได้ในน้ำมันและผู้ผลิตเครื่องจักรส่วนใหญ่ระบุว่า “สารเติมแต่งทั้งหมดต้องละลายได้” แม้ว่าจะได้รับการยกเว้นหนึ่งครั้งซิลิโคน Antifoam บางครั้งสามารถกระจายในน้ำมันไม่เพียงพอและปรากฏเป็นหยดที่มีขนาดใหญ่กว่าพวกเขา ควรจะเป็น. พวกมันจะจับตัวเป็นก้อนถ้ามีอนุภาคอยู่และถ้ามีขนาดใหญ่พอตัวกรองก็จะทำการกำจัดสิ่งที่น่าสนใจก็คือถ้าซิลิโคนจับตัวเป็นก้อน พวกเขายังคงปรากฏในการวิเคราะห์สเปกตรัม แต่พวกเขาไม่ได้ใช้งาน ดังนั้นตัวกรองจะได้รับการตำหนิโดยไม่คำนึงว่าความสามารถของ AF จะไม่เปลี่ยนแปลงหากคุณควรเปรียบเทียบน้ำมันทั้งสอง (น้ำมันที่มีตัวกรองที่มีประสิทธิภาพเทียบกับน้ำมันที่ไม่มีตัวกรองและนับอนุภาคสูง) วิธีง่ายๆในการใช้อะคริเลตเป็น AF แต่แน่นอนว่าสิ่งนี้แสดงให้เห็นในราคาตั๋ว และโปรดระวังไม่ว่าในกรณีใด ๆ อนุภาคที่น้อย��ว่าที่ระบุในมาตรฐาน (NAS หรือ ISO) จะไม่ถูกนับรวม คุณสามารถมีความสะอาดตกลงบนกระดาษ แต่ในชีวิตจริงน้ำมันเป็นสีดำสนิทเพียงน้ำมันเครื่องดีเซล นอกจากนี้ระวังว่าการวิเคราะห์ / นับอนุภาคเพียงครั้งเดียวแสดงให้เห็นถึงช่วงเวลา “ตัวกรองอนุภาคขนาดเล็กในช่วง 0.5 ไมครอนถึง 5.0 ไมครอนจะกรองสารเติมแต่งจากน้ำมันหล่อลื่นหรือไม่ถูกต้องหรือไม่ว่าสารเติมแต่งเหล่านี้ส่วนใหญ่ละลายได้ในน้ำมันและที่ไม่ได้มีขนาด 0.05 ไมครอนหรือน้อยกว่า ?

10 Ways to Reduce Costs and Boost Welding Productivity

Welding is a cost-effective manufacturing process. However, several factors can significantly increase or reduce the cost-effectiveness and productivity of a welding project. These range from operational efficiency to the use of consumables.

In this article, we will go through 10 ways to significantly reduce welding costs and boost the productivity of welding projects.

1. Avoid Overwelding

Overwelding occurs when a weld is larger than it needs to be. This is a common occurrence in the welding industry, especially with inexperienced welders. An overweld may result when there is no specified weld size in a design, when there is no fillet weld gauge, or when a big weld is created just to play it safe.

Overwelding is a significant resource drain; it uses more arc time, labor, shielding gas, and filler metal, which leads to higher costs. To put this waste into perspective, consider a 1/4″ overweld instead of a required 3/16″ weld: The overweld results in a 78% increase in both weld metal deposition and arc-on time. This goes up to 177% when the overweld is 5/16″.

Increased cost and time are not the only negative implications of overwelding. Bigger-than-required welds tend to distort more because of the increased heat input. Also, excessive convexity may increase the likelihood of a weld failing due to fatigue. In groove joints, excessive reinforcements do not create stronger welds compared to welds that are flush (or just above) the base material surface.

To save resources and time, stick to weld specifications in designs, make use of a fillet weld gauge, and avoid excessive reinforcements on groove joints. A change in wire diameter may also be used to avoid overwelding.

2. Employ Weld Automation

Weld automation is the use of equipment that automates part or all of the welding process. Human operators, no matter how skilled, are susceptible to fatigue. They can also make errors during welding or other related activities (e.g., positioning and handling pieces of the weldment). These factors, coupled with safety concerns, can affect the productivity of welding.

There are numerous types of automation equipment that can greatly increase productivity and save cost. However, different levels of automation can be applied in welding, and the term automation doesn’t necessarily mean robotic welding. For example, hard automation is the use of weld positioners, manipulators, and turning rolls to keep a weldment in place. There are also fully automated setups in which the actual welding is carried out by robotic arms—this is known as robotic welding.

The use of automation makes welding safer, faster, more productive, and more cost-effective. Compared to humans, machines are quicker, more consistent, and less prone to errors. Machines are also easily programmable, thus reducing the cost of hiring, managing, and training human workers.

3. Use the Right Welding Process

Weld aesthetics To effectively boost productivity, it is important to review all these factors before selecting a welding technique. For example, welding is more precise than metal inert gas (MIG) welding but requires more skill. If aesthetics is an important consideration, TIG should be used, as MIG would cause you to spend more time later on in finishing. There is no need to select the submerged arc welding (SAW) process, with its high deposition rate of , when your project only requires the 5 lb/hr deposition rate of stick welding.

To make sure that you are not consuming more resources than necessary you need to review all considerations. Also, selecting the wrong process may lead to the production of rejects.

4. Handle and Arrange Materials Properly

The proper handling of materials during welding is crucial to improving productivity. Valuable time is wasted when a welder has to stop a welding process, go somewhere else to look for (and procure) a needed welding accessory, return to the welding spot, and resume welding. Even more time is wasted when weldment pieces are scattered around the welding area. While these short interruptions may seem trivial, they add up to significant time-related costs.

Before welding begins, all consumables, welding accessories, and parts to be welded should be sorted out and arranged in proximity to the welder.

5. Properly Maintain All Welding Equipment

The importance of having equipment in excellent condition for productivity and cost savings can hardly be overemphasized, as faulty equipment may consume more resources while generating more waste.

Frayed cables and faulty appliances can lead to voltage losses, wire feeding problems, and erratic arcs. Likewise, faulty gas systems can lead to gas leakage. All these contribute to the potential inefficiency of welding operations.

There is also the problem of defective equipment producing poor-quality welds, which may lead to more rejects, compromised worker safety, and costly downtime.

Investing in a comprehensive preventive maintenance program reduces costs in the long run.

6. Prepare Joints and Gaps Properly

Adequate preparation of joints is required for a hitch-free welding process. To start, welding operators should carefully clean the surface of the base materials. This will help prevent contaminants, such as dirt and oil, from entering the weld puddle. Next, welding operators must ensure they have the right fit-up and no excessive gaps.

A poor fit-up can have numerous negative consequences. One example is the potential for distortion or burn through, which compromises the strength of welds. Poor fit-up also leads to overwelding, as gaps increase the size of weld required to achieve the same load-bearing capacity. For example, a 1/4″ fillet is required for a joint when there is no gap. A gap of 1/8″ in that same joint would require a new fillet size of 3/8″ to achieve the same strength. That amounts to a 124% increase in filler metal consumption.

7. Control the Use of Consumables

Consumables such as shielding gas, filler material, anti-splatter compounds, grinding wheels, back bars, and gun components account for a noteworthy portion of the total welding cost. As a result, their proper use is important in keeping costs low. Certain consumables should only be used when necessary.

Gas delivery systems should be checked regularly so that leaks can be identified and sealed off. Surge turbines and surge guards can be attached to the end of welding guns to measure gas surge and reduce pressure, respectively.

8. Boost Efficiency

Labor cost is the largest cost variable in any welding project. One way to reduce this cost and boost welding productivity is by ensuring efficiency in all operations. The following operations are all time-dependent activities that can be optimized:

Preparing the metal for welding

Preparing the joint

Assembling components

Preheating, if required

Tack welding components, if required

Positioning/repositioning , if required

Moving between welds

Interpass cooling, if applicable

Grinding spatter

Inspecting and testing for

Reworking/repairing of welds and subsequent

Postweld heat treating, if applicable

It is evident that a lapse in one operation can have a domino effect on the operations that follow it. For example, poorly prepared joints can lead to overwelding, which in turn can lead to avoidable grinding and polishing. Likewise, poor positioning may lead to reworking and repairing of welds.

While inefficiencies in operations may be difficult to track and measure, the rewards are worth the effort. An effective way to spot inefficiencies is as follows: If step 2 is a required process for step 3, then all is in order. However, if step 2 is carried out to correct or optimize step 1, then there are inefficiencies inherent in step 1.

Another way of boosting productivity is by using technology that enhances efficiency. One of which is with cable length compensation (CLC), adjust while welding (AWW), Auto-Line, and SuitCase wire feeder which delivers smooth wire feeding with accurate, consistent speed. These boost productivity and reduce labor time and cost.

9. Minimize Rejects and Reworks

When a reject is produced, 100% of the filler material, shielding gas, electricity, labor, and time used is wasted. This is terrible for cost savings. Reworks also result in wasted time, resources, and labor. Ensure that through skill and efficiency, rejects and reworks are eliminated.

10. Prioritize Welding Safety

While they do not directly contribute to welding costs, workplace accidents are never desirable nor do they contribute to the efficiency of any production environment. Worker safety should always be a top priority in any company.

Ensure that you take all necessary precautions and follow the pertinent guidelines and regulations to maintain the safety of welding operators throughout a welding project. High-quality safety gear and comprehensive safety plans help to prevent injuries and save costs in the long run.”

Conclusion

The 10 ideas we’ve presented here could greatly improve your welding profitability and productivity.”Further cost- and time-saving opportunities may be discovered by carefully analyzing your welding operations.

LAB VACUUM FURNACES

INTRODUCTION OF EXPERIMENTAL ELECTRIC FURNACE

The experimental electric furnace has many advantages in the course of operation, but some experimental electric furnaces have a certain influence on the work if they are used for a long time. This is also very important for the maintenance of the electric furnace. In the process of using the experimental electric furnace, do not stay in the tube area of the experimental electric furnace for a long time except for the test. Wear gloves when dealing with HF to avoid burning. If you accidentally touch HF, flush immediately, add 2% water with calcium gluconate and rub the abrasion area for 15 seconds. The experimental electric furnace steelmaking mainly uses arc heat, in the arc action area, the temperature is as high as 4000 degrees Celsius. Smelting process is generally divided into melting stage, oxidation stage and reduction stage, in the high temperature furnace can not only create an oxidation atmosphere, but also a reduction atmosphere, so the efficiency of dephosphorization and desulfurization is very high. We can add hot metal, pig iron, direct reduced iron, hot briquetting, etc. The smelting time is longer, generally at least two times of the converter smelting time. The arc zone temperature of the electric arc furnace is as high as 3000-6000 C and the furnace temperature is as high as 2016 C, which is much higher than the temperature needed for smelting general steel. It can be used to smelt alloy steel and stainless steel which can not be smelted by converter. It is a kind of high temperature heat treatment equipment. It can be used for long-term stability of the furnace. Therefore, it is widely used in alloy steel products, various metal parts normalizing, quenching, annealing, sintering, heat treatment ashing and so on. Applicable to all metal parts of alloy steel products, normalizing, quenching, annealing and other heat treatment, or diamond cutting blades, such as high temperature sintering furnace.

WHAT ARE THE CHARACTERISTICS OF THE EAF?

1. Powder spraying process of external material (SPCC) > 1.2 mm thick plate is formed by gathering silicon carbide or ceramic fiberboard inside. 2. Automatic controller and PID microcomputer calculus PV/SV display at the same time, the key; through heat treatment can adjust its mechanical properties of stainless steel, generally speaking, is a kind of hardening stainless steel. Typical brands are Cr13, such as 2Cr13,3Cr13,4Cr13. After quenching, the hardness is higher, and different tempering temperature has different strength and toughness combination. It is mainly used in steam turbine blades, tableware, surgical instruments. In many ways, there are different applications, these will have a huge relationship with our use, while its different uses and many different ways to classify the corresponding, these are one of its characteristics, and will be different from what we have. It is its work philosophy, but also closely related to the concept of life, life will provide a huge place to use.

THE OPERATION PROCEDURE OF THE LAB VACUUM FURNACES IS:

1. Check whether there are any obstacles in the track of the electric furnace before starting up. The wire rope, hoist, bracket and trolley must be in good condition and lubricated according to the regulations. 2, drivers must obey the command of furnace operators and cooperate closely. Lack of material placed at the bottom of the furnace, to use a steel ruler to insert three points (both ends and the middle), according to the size of the specified inspection, stove head corner of the lack of material to be fully stepped on to prevent wall burning salt. 3. The position of the furnace core should be determined accurately. The reaction box must be placed vertically, with a moderate height and a correct position. The distance between the two rows of boxes should be kept equidistant, and the width and dimension of the furnace core should be determined accurately. The four corners of the reaction chamber and the ends of the end walls are filled with paper. 4, when lifting the reaction box, the crane should be directed to the upright position and vertically lifted. Only when the box is fully allocated can the cart be lifted. It is strictly forbidden to lift the reaction box in the operation of the resistance electric furnace. Put the reaction box in order. The loader should place the removed four-chain hook in the box so as not to hang the outer edge of the box to make the box move or hurt the operator. 5. After each charging is finished, the hopper closer must be tightly closed. After charging, the waste material or graphite sprinkled on the end wall tie rod should be cleaned up. The winch trolley should be parked in a safe position, the top axle should be pressed up, and the cover should be well covered. The furnace number and the abnormal situation of the furnace should be filled in the process card, and the trolley should be transferred with the furnace. In order to avoid insulation failure, the dust in the machine room, the power cabinet and the induction coil with copper bars should be cleaned thoroughly under high temperature, high voltage and high current. We often check whether the cooling water and water pressure are normal. The screws and screw caps of each device should be tightened regularly to avoid contact failure and burn down devices. Regularly protect and maintain the shrinkage motor of water cooling system and the motor of hydraulic station, keep the hydraulic oil clean and ensure the normal water supply and oil supply of facilities. Regular implementation of the fixed voltage and current of the facility will avoid any effort to take care of the circuit.
