LAP JOINT STUB ENDS

A Lap Joint Stub End is a short piece of pipe or fitting welded directly to the end of a pipeline, featuring a flanged collar face on one end and a straight welding spigot on the other. It is used in tandem with a loose backing flange (such as an EN 1092-1 Type 02 or ASME lap joint flange) to create a movable, rotating flange connection.

Key Features

• 360° Rotational Alignment: Allows the backing flange to rotate freely during assembly, eliminating bolt-hole alignment issues.
• Cost Optimization: Only the stub end contacts the process fluid, allowing expensive stainless steel or alloy stub ends to be paired with economical carbon steel backing flanges.
• Easy Maintenance: Simplifies joint disassembly and gasket replacement in systems requiring frequent cleaning.

Applications

• Corrosive Chemical Lines: Stainless steel and alloy piping systems handling aggressive media.
• Pulp & Paper Processing: Slurry, chemical recovery, and bleaching lines.
• Water Treatment Plants: Large-diameter low-pressure utility lines and filter manifolds.
