Socket Weld Flanges Manufacturer
SOCKET WELD FLANGES
Socket Weld Flanges (SWRF) are counter-bored i.e. the bore of the Flange and pipe, both are same, thereby providing a good ow of the product through the pipe. Initially used for small-sized high-pressure pipes, our SMO 254 Socket Weld Flanges are now used in high-pressure systems too. Our Stainless Steel Socket Weld Flanges are oxidation resistant and promote better weldability and fabricability. We seek to offer ANSI B16.5 Carbon Steel Socket Weld Flanges that have excellent stress corrosion cracking resistance to the LNG, seawater and mining industry.

Frequently Asked Questions About Socket Weld Flanges
Why is an expansion gap required when welding Socket Weld Flanges?
When installing a Socket Weld flange, the pipe is inserted into the socket until it bottoms out, and then backed off slightly to create an expansion gap (typically 1/16 inch or 1.6 mm) before welding. This gap allows for thermal expansion of the pipe and prevents bottoming out stresses that could cause the weld to crack under load or thermal cycling.
Frequently Asked Questions
What pressure classes are available for your Socket Weld Flanges?We manufacture forged socket weld flanges strictly adhering to ASME B16.5 dimension standards, available in 150#, 300#, 600#, 900#, 1500#, and 2500# pressure classes. These high-pressure ratings are ideal for critical, leak-free pipeline configurations.
What is the benefit of using Socket Weld connections?Socket weld flanges feature a recessed area where the pipe is inserted before welding. This eliminates the need for complex pipe beveling and ensures precise alignment, making them the preferred choice for smaller diameter pipelines (typically NPS 2 or smaller) in high-pressure systems.
Which material grades do you stock for Socket Weld Flanges?We stock and supply forged flanges in a comprehensive range of materials, including Stainless Steel (ASTM A182 F304/F304L, F316/F316L), Carbon Steel (ASTM A105), Alloy Steel, and Duplex steel, ensuring chemical compatibility with any industrial fluid.
Are your Socket Weld Flanges tested for high-pressure applications?Yes. All Gandhi Metal India forged flanges undergo rigorous testing to ensure there are no micro-cracks before they are shipped to refineries or EPC projects.
