Weld End Expansion Joints
Weld end expansion joints are equipped with carbon steel or stainless steel pipe connections, welded directly into the pipeline. Primarily used for axial movement, though a universal type is recommended if lateral movement is the main requirement. Available with limit rods, liners, covers, rods, hinges, or gimbals, and can be supplied with a double bellows design for higher lateral movement absorption. Bellows are calculated to the latest EJMA standards.
