Steelage Alloys manufactures and supplies high-quality Stainless Steel Stub Ends, an essential component in piping systems designed for Lap Joint Flanges. Stub ends are used where quick disassembly and frequent inspection are required, making them a preferred choice in industries that demand hygiene, flexibility, or corrosion resistance.
Made from corrosion-resistant stainless steel, our stub ends offer excellent mechanical strength, precise dimensions, and smooth finishes. Available in short and long pattern designs, they reduce flange costs in large-diameter, high-pressure pipelines by allowing repeated reuse of the backing flange.

A stub end is used with a lap joint flange assembly and provides the sealing face while allowing the backing flange to rotate for alignment.
The stub end is welded to the pipe, and the backing flange fits over it and can rotate for bolt-hole alignment. The assembly must meet the piping specification.
Confirm grade, pipe size, schedule, lap-joint dimensions, end preparation, standard and quantity.
