A lap-joint stub end is used in conjunction with a loose-fitting (lap-joint) flange; the welded end connects to the piping, while the flanged end provides the sealing surface. The loose flange can rotate freely to facilitate bolt-hole alignment. This configuration is suitable for systems requiring frequent disassembly or the use of corrosion-resistant piping materials.

Reference Standards: ASME B16.9 for butt-weld lap joint stub ends; MSS SP-43-2026 for low-pressure, corrosion-resistant, thin-wall systems.
Configuration: Long or short pattern stub ends; specifications include NPS/DN, wall thickness, barrel length, lap outside diameter, lap thickness, and fillet radius.
Connection: Butt-weld at the barrel end; lap end mates with a lap joint flange and gasket.
Materials: Carbon steel, stainless steel, or alloy steel; lap material must be compatible with the process medium.
Pressure Rating: Determined by the combination of fitting wall thickness, material, lap joint flange, and gasket system.
Ordering/Acceptance: Confirm pattern (long/short), nominal size, wall thickness, barrel length, lap dimensions, fillet radius, and material; ensure compatibility with the mating lap joint flange, gasket, and bolting system.
