Description
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 Titanium Socket Weld Flanges are oxidation resistant and promote better weldability and fabricability. We offer ANSI B16.5 titanium Socket Weld Flanges that have excellent stress corrosion cracking resistance to the LNG, seawater and mining industry. Baoji QiYueXin Metal Materials Co., Ltd. (QYX), deliver our premium quality products to all our valued customers in the shortest time span.
