ASME B16.9 Buttweld Pipe Fittings , ASTM A403 WP304 Stainless Steel Lap Joint Stud Ends
A stub end is a short piece of pipe with a flange on one end and a lap joint on the other. It is designed to be used with a matching lap joint flange and allows for easy disassembly for maintenance or inspection. Ensure that the steel stub end material matches the piping system in terms of corrosion resistance and mechanical properties. Typically made of carbon steel, alloy steel, stainless steel, or other materials to match the piping system's requirements.
