Series 1500 Laminated Bellows Expansion Joints

Series 1500 Laminated Bellows Expansion Joints are designed for installations where the principal movement is axial. Standard designs are 2” through 14” NPS with 2” or 3”axial compression. Service conditions are 150 PSIG or 300 PSIG to 500°F.

The bellows element is integrated into the design to provide the minimum effective area and resulting pressure thrust. The laminated construction results in the optimum cycle life and lowest possible spring constant. A stainless steel flow liner is standard with negligible reduction of flow area and resulting flow interference. Standard Series 1500 Laminated Bellows Expansion Joints are available from stock, and they have a Five Year Full Replacement Warranty.



Series 8500 Expansion Compensators are comparable products that are available in smaller diameters. Steel pipe and copper tube configurations available.

Series 3500 Externally Pressurized Expansion Joints are comparable products with greater travel. Standard designs are available through 24”.

Series 9500 Alignment Guides are designed to maintain the alignment of the pipe adjacent to expansion joints, and as intermediate guides throughout the pipe run.
