Product Details

Stainless Steel Stub Ends

Stainless steel stub end, also known as stainless steel lap joints and stainless steel flare laps, is a pipe fitting used in place of welded flanges where rotating back up flanges are desired. A rotating back up flange seats itself against the back surface of the stub end. The seal is made by the gasket surface of the stub end alone, the flange only provides the clamping pressure on the joint. There are two main types of stainless stub ends: seamless stainless steel stub end and welded stainless steel stub end. Different production processes are adopted according to different types. We always use press forming to produce seamless stainless stub end and argon arc welding to form welded stainless stub end. The size of stainless stub end we manufacture ranges from DN15 to DN1200. This is just the start instead of the completion of our service when products are delivered to you. We offer you most comprehensive after sales service and ensure best operational performance of our products. For metal, we are serious.
