7 Types of Flanges Every Industrial Customer Should Know

Flanges are an integral component in many industrial applications, especially in the construction, petrochemical, and oilfield industries. They are used to connect pipes, valves, pumps, and other equipment in a piping system. A flange provides a secure and leak-proof joint, which is critical in applications where fluids or gases are transported at high pressures or temperatures. In this blog post, we will discuss the seven most common types of flanges used in industrial settings.

Blind Flange

A blind flange is a flat plate with bolt holes that is used to close the end of a piping system. It is commonly used in applications where future expansion or maintenance may be required. Blind flanges are also used to cap off pipes or valves that are not in use. They are available in a range of sizes and materials to suit different applications.

Weldneck Flange

A weldneck flange is a type of flange that has a long tapered hub and a neck that is welded to the pipe. The neck provides reinforcement to the pipe and allows for easy alignment during installation. Weldneck flanges are commonly used in high-pressure applications or in pipelines that carry corrosive fluids. They are available in various sizes and materials.

Slip on Flange

A slip-on flange is a flat plate with a bore that slips over the end of a pipe. The flange is then welded to the pipe, creating a secure and leak-proof joint. Slip-on flanges are commonly used in low-pressure applications or in pipelines that carry non-corrosive fluids. They are available in a range of sizes and materials.

Socket Weld Flange

A socket weld flange is a type of flange that is welded to the pipe using a socket weld connection. The socket weld connection provides a high-strength joint and allows for easy alignment during installation. Socket weld flanges are commonly used in high-pressure applications or in pipelines that carry corrosive fluids. They are available in various sizes and materials.

Threaded Flange

A threaded flange is a type of flange that has threads on the inside bore and outside diameter. The flange is screwed onto the pipe, creating a secure and leak-proof joint. Threaded flanges are commonly used in low-pressure applications or in pipelines that carry non-corrosive fluids. They are available in a range of sizes and materials.

Lap Joint Flange

A lap joint flange is a type of flange that is used with a stub end. The stub end is welded to the pipe, and the lap joint flange is bolted to the stub end. Lap joint flanges are commonly used in applications where frequent disassembly is required. They are available in various sizes and materials.

Long Weldneck Flange

A long weldneck flange is similar to a weldneck flange, but it has a longer neck. The longer neck provides additional reinforcement to the pipe and allows for easy alignment during installation. Long weldneck flanges are commonly used in high-pressure applications or in pipelines that carry corrosive fluids. They are available in various sizes and materials.

In conclusion, flanges are a critical component in industrial piping systems. Choosing the right type of flange for your application can ensure a secure and leak-proof joint, which is essential for maintaining the safety and efficiency of your operation.
