Steel Socket Weld Flange

Socket weld flanges, also known as SW flanges, have a recessed area (like a
shoulder) in the flange bore. This shoulder serves as a guide to set the depth
of the pipe that is inserted into the flange.

Socket weld flanges are a less common but equally effective connection for
flanges that require less overall available space than a traditional weld neck
flange, with a counterbore in the center to allow for a clean weld of pipe into
the socket.

The advantage of socket weld flanges is their simple design; they are well-
suited for small pipe size applications, and for non-critical applications,
e.g., non-hazardous systems; they are not suitable for highly erosive or
corrosive systems.

welding flanges (slip-on, weld neck, or blind flange).
Socket Weld Flanges Application:
Socket weld flanges are commonly used in high-pressure piping systems such as
chemical processing, petrochemical refining, oil and gas, and power generation
systems.

These flanges efficiently connect pipes to valves, fittings, and equipment
while offering high reliability and safety.

In some instances, socket weld flanges are used in small-bore piping systems
such as steam, air, water, and gas pipelines where high pressure and
temperatures exist.

Key Features:
Material: Manufactured using superior quality steel, offering high strength,
durability, and corrosion resistance.
Sizes: Available in diverse sizes to accommodate various pipe diameters. Custom
sizes also available on request.
Standards: Complies with ASME B16.5 and B16.47 standards, ensuring high-quality
and compatibility with a wide range of pipe fittings.
Design: The recessed design of the socket weld flange allows for precise
alignment of the pipe and flange, reducing the risk of leakage.
Applications: Perfect for high-pressure applications and smaller pipe sizes.
Widely used in industries such as oil & gas, chemical processing, power
generation, and more.

Socket Weld Flange vs Slip On Flange
Socket welded flange shape is similar to slip on flange, differently it has a
shoulder at the inner bore.

Slip On Flange – No shoulder at inner bore.

Socket weld flange static strength is equal to slip on flange, but it’s
fatigue strength is 50% higher than the double welded slip on flange.
