High Quality A182 F304 Flanges We Can Supply

304L is a low-carbon version of 304 stainless steel, offering excellent corrosion resistance and improved weldability, particularly in preventing intergranular corrosion after welding. Weld neck flanges are suitable for high-pressure and high-temperature piping systems, connected to pipes by butt-welding to ensure consistent strength between the pipe and the flange. The raised face design enhances the sealing between the flange and the gasket.

Our range of A182 F304L encompasses various types:

Types : Weld Neck (WN), Long Weld Neck (LWN), Slip-On (SO), Blind, Lap Joint, Socket Weld (SW), Threaded, and Other Products
Size: 1/2″ – 48″
