socket weld flange / SWRF flange

About socket weld flange / SWRF flange

Socket Weld Flanges (SWRF) are designed for small-diameter, high-pressure pipelines, ensuring strong and leak-proof connections. The pipe is inserted into the socket end and fillet-welded around the hub, providing a smooth bore with better flow characteristics. Induskart offers forged SWRF flanges in Carbon Steel, Mild Steel, and Stainless Steel, manufactured to ANSI B16.5 standards for dimensional accuracy and performance reliability.
