These vital connectors provide stability, leak resistance, and ease of maintenance in piping systems. In this article, we will explore the different types of industrial flanges, their applications, and the benefits they offer. Types of Industrial Flanges Industrial flanges come in different types, each suited for specific applications and requirements. Let's explore some of the commonly used types: Weld Neck Flanges Weld neck flanges are highly reliable and popular in industries that require high-pressure and high-temperature applications. They have a long tapered hub, which gradually merges with the pipe, providing enhanced strength and reducing stress concentrations. Slip-On Flanges Slip-on flanges are easy to install and cost-effective. They slide over the pipe and are then welded in place. These flanges are ideal for low-pressure applications and non-critical systems. Socket Weld Flanges Socket weld flanges are similar to slip-on flanges but have a socket-like end for pipe insertion. Smaller pipe sizes and high-pressure systems commonly use them due to their excellent fatigue resistance. Blind Flanges Blind flanges are used to seal off the ends of pipes, valves, or pressure vessel openings. They are solid discs without a center hole and provide an effective closure for piping systems.

Different Types of Flanges Used in Piping Applications - Arcellors Controls

Flanges are an essential component in piping applications, connecting pipes and equipment to ensure the safe and efficient transfer of fluids. They are used to create a secure and leak-proof connection between pipes, valves, pumps, and other equipment, and are available in a wide range of types including, Weld Neck Flanges, Slip-On Flanges, Blind Flanges, Lap Joint Flanges, Threaded Flanges, and Socket Weld Flanges and materials like Stainless steel, Duplex & Super Duplex Steel, Carbon Steel, Low-Temperature Carbon Steel, Alloy Steel, Copper Alloy Steel Flange, and Nickel Alloy to meet different requirements.

In this blog post, we will discuss the different types of flanges used in piping applications, the materials used in their production, and the standards that govern their manufacture. 

We will also highlight the advantages of choosing Arcellor Controls India as your flange supplier, and answer some frequently asked questions about flanges.

Flanges and Their Importance in Piping Applications

Flanges are essentially flat, circular disks with holes for bolts, designed to connect pipes and equipment in a piping system. They serve several critical functions, including:

Allowing for easy assembly and disassembly of piping systems for maintenance and repair

Providing a secure seal to prevent leakage or loss of pressure

Supporting heavy loads and vibrations in piping systems

Different Types of Flanges Used in Piping Applications

Flanges are available in a wide range of types, each with its own unique features and benefits. Here are some of the most common types of flanges used in piping applications:

Weld Neck Flanges:

Weld neck flanges are designed to be butt-welded to the end of a pipe, creating a smooth transition from the pipe to the flange. They are used in high-pressure and high-temperature applications, where the weld neck provides additional strength and support.

Slip-On Flanges:

Slip-on flanges are designed to slide over the end of a pipe and are then welded in place. They are typically used in low-pressure applications, where the weld provides sufficient strength and support.

Blind Flanges:

Blind flanges are used to close the end of a pipe, valve, or other equipment, creating a seal that prevents the escape of fluids or gases. They are commonly used in pressure vessel applications, where they provide a secure and leak-proof closure.

Lap Joint Flanges:

Lap joint flanges are used in applications where frequent assembly and disassembly is required. They consist of two parts: a stub end and a backing flange, which are bolted together. The stub end is welded to the end of a pipe, while the backing flange provides the connection to the equipment.

Threaded Flanges:

Threaded flanges are used in applications where a secure and leak-proof connection is required, but welding is not feasible. They are designed to be screwed onto the end of a pipe, and can be easily assembled and disassembled.

Socket Weld Flanges:

Socket weld flanges are similar to slip-on flanges, but are designed to be welded to the end of a pipe using a socket weld connection. They are commonly used in small-diameter piping applications, where they provide a secure and leak-proof connection.

Types of face type flanges

At Arcellor Controls (India) we do also offer various types of face type flanges including:

Flate Face  (FF): 

Flat face flanges are a type of flange used in piping applications that require a flat sealing surface between two flanges. These flanges are typically used in low-pressure applications where metal-to-metal sealing is required.

Flat face flanges have a flat surface with no protrusions or lips. They are usually bolted together with another flat face flange or with a raised face flange using gaskets to prevent leaks. The gasket sits between the two flanges and compresses when the bolts are tightened, creating a seal.

Raised Face (RF):

Raised face flanges are another type of flange used in piping applications that require a sealing surface between two flanges. Unlike flat face flanges, raised face flanges have a raised surface around the bolt holes to provide additional surface area for sealing.

The raised surface creates a ridge around the bolt holes, which can help to center the gasket and prevent it from slipping out of place. This can help to create a more secure seal and reduce the risk of leaks.

Raised face flanges are typically used in higher pressure and temperature applications, where a more robust seal is required. They are often used in applications involving corrosive fluids, where the flange material needs to be resistant to corrosion.

Ring Type Joint (RTJ):

Ring Type Joint (RTJ) flanges are a type of flange used in high-pressure and high-temperature piping applications. These flanges have a groove around the perimeter of the flange face that is designed to accommodate a metal ring gasket.

RTJ flanges are typically used in applications where the pressure and temperature are too high for other types of flanges, such as raised face or flat face flanges. The metal ring gasket provides a secure and reliable seal, even under extreme conditions.

Standards Governing Flange Manufacture

At Arcellor Controls (India) Flanges are produced in accordance with various international standards to ensure their quality, safety, and compatibility with other components in the piping system. We do offer flanges in ASME/ANSI Standards for piping system;

ASME/ANSI

The American Society of Mechanical Engineers (ASME) and the American National Standards Institute (ANSI) have developed a range of standards governing the design, manufacture, and testing of flanges for use in high-pressure and high-temperature applications.

What is a Flange?

A flange is a mechanical device used to connect pipes, valves, or pumps together. It provides strength, seals, and easy disassembly of piping systems. Flanges are typically welded or screwed onto pipes and sealed with gaskets and bolts.

Types of Flanges and Their Applications

🔹 1. Blind Flange

What it is: A flange with no bore (no center hole)

Use: To seal the end of a piping system or pressure vessel

Common Applications: Testing pipe pressure, isolating pipe sections

Advantages: Easy to remove for inspection; strong seal under pressure

🔹 2. Weld Neck Flange

What it is: Flange with a long tapered hub welded to the pipe

Use: For high-pressure, high-temperature applications

Common Applications: Oil and gas pipelines, power plants

Advantages: Excellent strength; reduces stress concentration

🔹 3. Socket Weld Flange

What it is: Pipe inserted into flange socket and welded around

Use: Small-diameter high-pressure pipelines

Common Applications: Chemical and hydraulic pipelines

Advantages: Smooth bore flow; better fatigue strength than slip-on flanges

🔹 4. Lap Joint Flange

What it is: Flange used with a stub end; not welded to the pipe

Use: Systems requiring frequent dismantling

Common Applications: Low-pressure systems, food-grade pipelines

Advantages: Easy alignment; cost-saving for expensive pipe materials
