Seamless Steel Boiler Tubes: An Overview

A boiler is a closed device that heats fluid (usually water) within it. It does not steam the gas. The heated and vaporized fluid comes out of the boiler relying on Boiler tubes, cooking, and sanitation for use in different methods or heating applications such as water heating, central heating, power generation.

There are two major types of tube Boiler tubes:

· Water-tube Boiler Tubes

· Fire-tube Boiler Tubes

Water-tube Boiler tubes:

A boiler with a high-pressure water tube is a boiler in which water flows in the tubes externally heated by the gases. Within the furnace, fuel is burnt, stimulating hot gas that heats water in the tubes to produce steam. In smaller Boiler tubes, the furnace is isolated by external heating tubes, whereas larger service Boiler tubes depend on the water-filled tubes that insist the furnace walls produce steam.

Fire-tube Boiler tubes:

A fire-tube boiler is a type of boiler where heated gasses, generated from a flame, flows through one or more tubes and then flow through a sealed water tube. The heat of the gasses is transferred after thermal conduction through the tube walls, heating the water and eventually producing vapor. This kind of boiler has been used in the horizontal locomotive configuration on nearly all steam locomotives. The fire tube boiler has a tubular container that holds the fire tubes having an extension to fit the one-end firebox. This firebox has an open foundation to have a wide grate area that also stretches out to create a rectangular or tapered structure outside the cylindrical container.

Materials used for Manufacturing of Boiler Tubes:

A boiler tube is typically made of steel (or steel alloy) or traditionally produced from wrought iron. Due to corrosion, and stress corrosion cracking, stainless steel, particularly of the austenitic forms, is not used in moistened sections of Boiler tubes. However, ferritic stainless steel can be frequently found in overheated areas not meant for boiling water. Electrically heated, stainless steel seamless Boiler tubes are used for steam processing in sterilizers and disinfectors under the European “Pressure Device Guideline.”

Copper or brass is also in use to make live steam versions since it is cheaper to form smaller Boiler tubes from these metals. Traditionally, copper is often used in fireboxes because it delivers better formability and higher thermal conductivity. But, in more recent years, the copper prices have rendered this an economical option and then use the affordable alternatives (such as steel).

The only commodity used in boiler construction during most of the ancient “era of steam” was the lowest quality of wrought iron, having a mounting by riveting. This type of iron was mostly sourced from specialist ironworks known for the high nature of their rolled steel, which was particularly ideal for use in essential applications such as high-pressure Boiler tubes. Technology innovation in the 20th century shifted towards steel usage, of welded and seamless type of productions, which is safer and simpler, which can be crafted quicker and with less labor involved. Wrought iron Boiler tubes develop corrosion even more gradually than their counterparts in conventional steel. As a result, they are less prone to irregular pitting and stress corrosion. The longevity of older wrought-iron Boiler tubes is therefore far superior to that of welded steel Boiler tubes.

Here is the stainless-steel seamless boiler tubes ideal for use in high-pressure and low to medium pressure boiler tubes. This kind of tubing mainly includes ASTM A179, ASTM A106, and JIS G3454. As they are made of stainless steel, they have stronger resistance against corrosion than those tubes made of other metals. Since the boiler tubes deal with high pressure, they should withstand the pressure at their best. Seamless tubes and pipes devoid of any weld prove to be more trustworthy to handle pressure and resist pitting and breakage problems. Several steel boiler tube manufacturing companies in India specialize in producing seamless boiler tubes using the most advanced technologies. Ideally, these manufacturing units are also equipped with high-end quality testing machines that ensure the quality and longevity of the products detecting every minute defect in the first place.

Heat Treatment Process of Seamless Steel Pipe

Heat treatment is a controlled process used to alter the microstructure of metals and alloys such as steel and aluminium to impart properties which benefit the working life of a component, for example increased surface hardness, temperature resistance, ductility and strength.

Heat treatment processes include case hardening, tempering, solution and aging treatment, Specialty Stainless Steel Processes (S3P), annealing and normalising.In recent years, with the advancement of science and technology and its application, heat treatment process for seamlesssteel pipe is mainly reflected in the following aspects:

Clean the heat treatment

Heat treatment production waste water, waste gas, waste salt, dust, noise and electromagnetic radiation and so impact on the environment caused by pollution. Solve the heat treatment of environmental pollution problems, the implementation of clean heat treatment (or the green heat treatment) is one of the developed countries the direction of heat treatment technology development. To reduce SO2, CO, CO2, dust and cinder emissions, has basically put an end to the use of coal as a fuel, heavy oil use fewer, mostly switch to light oil, natural gas is still the best fuel. The burning furnace waste heat utilization has reached a high degree of, the burner structure optimization and empty – fuel ratio strictly controlled to ensure that under the premise of reasonable burning, reduce to a minimum the NOX and CO; gas carburizing, carbonitriding alternative salt treatment and vacuum heat treatment technology to reduce waste containing salts and CN-toxic water pollution; using water-soluble synthetic quenching oil instead of part of the quenching oil, using biodegradable vegetable oil instead of part of mineral oil to reduce oil pollution.

Precision heat treatment

Precision heat treatment has two meanings: the one hand, according to the requirements of the use of the parts, materials, structure size, physical metallurgy knowledge and state-of-the-art computer simulation and testing technology, to optimize the process parameters to achieve the desired performance or maximize material Another aspect of the potential; fully guarantee the stability of the optimization process to achieve product quality and degree of dispersion is small (or zero), and the heat distortion zero.

Energy-saving heat treatment

Scientific production and energy management is the most efficient use of energy has the potential factors, the establishment of a specialized heat treatment plant to ensure full capacity, give full play to the equipment capacity is the choice of the scientific management. Select energy structure in the heat treatment of primary energy; make full use of the waste heat, waste heat; using low-energy, short cycle process instead of a long cycle, energy consumption process.

Less non-oxidation heat treatment

Heated to precisely control the carbon potential protective atmosphere heating alternative oxidizing atmosphere, controlled atmosphere heated nitrogen potential, to improve the performance of the parts after heat treatment, heat treatment defects such as decarbonization, cracks, greatly reducing the heat after finishing stay reduced, improve the efficiency of material utilization and machining. Vacuum plus hot gas quenching, vacuum or low-pressure carburizing, nitriding, carbon permeation and boronizing can significantly improve the quality and reduce distortion, and increased life expectancy.

Color Codes in Pipes

Pipe color coding is important both for logistical and safety considerations. Color codes are, in some cases, applied on pipes and other piping materials (such as pipe fittings, flanges, and valves) to facilitate the identification, in the storage warehouse or on the field during project execution, of components manufactured in different materials. This is the case of complex plants using, at the same time, carbon, alloy, stainless steel piping products. When a piping system conveys fluids of different types, color codes are applied to distinguish the piping components by media.

The quality of heat treatment is directly related to subsequent processing quality and eventually affect the performance and life of the parts. Heat treatment of seamless steel pipes is also can be provided by leading steel pipe manufacturing companies which have integrated steel heat treatment plant. These companies facilitate with reliable, repeatable results. In these plants heat treatment operations are managed by some of the best engineers and technicians in the industry, with the experience and expertise to provide vital support and a real understanding of customer requirements for seamless tubes & pipes.
