HGFF Group Co., Ltd. (HGFF), the ISO enterprise known for its innovative products in China and abroad, specializing in on – time delivery. We deliver our premium quality products to all our valued customers in the shortest time span. 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.
