Stub ends form part of lap-joint flange connections. Explore the neck and lap details, then specify the material, dimensions and flange arrangement your project requires.
Sizes & dimensional standards ↓The stub end is one component in a flange assembly. Confirm its fit with the backing flange, gasket and adjoining piping.
The tubular end is welded to the pipe. Specify the pipe dimensions, wall thickness and end preparation required by the project.
The lap provides the face used in the joint, while the backing flange provides the bolted connection. Their mating geometry must be compatible.
Specify whether your enquiry is for stub ends only or a complete assembly. A stub end enquiry does not by itself define the backing flange, gasket or bolting supply.
Use the applicable standard or approved drawing to identify the exact configuration.
State the required pattern and overall length. Installation space, welding access and the project specification determine which dimensions are required.
Include the stub end type where specified, lap diameter, thickness and radius requirements. Provide the mating flange details for review.
Explore the material families, then confirm the grade and availability for your requirement.

A stub end is used as part of a lap-joint flange arrangement. Its neck joins to the pipe, and its lap works with the backing flange and the mating joint components.
State the supply scope in your enquiry. If the backing flange, gasket or bolting is required, specify those components separately so the quotation can identify what is included.
The patterns differ in length. Specify the required pattern and dimensions according to the applicable standard or approved drawing, including the space needed for installation and welding.
No. Include wall thickness, material, length, lap geometry and the mating flange details. Those requirements need to be reviewed together for the intended assembly.
