Series 3500 External Pressure Bellows Expansion Joints

Series 3500 Externally Pressurized Expansion Joints are designed for installations where the principal movement is axial. Standard single and dual designs are available 2” through 24” NPS with 4” through 16” axial compression. Service conditions are 150 and 300 psig to 500°F. Welded and flanged end connections are standard, with grooved ends optional.

Standard in-line pressure balanced configurations are available 2” through 24” NPS with 4”, 6” & 8” axial travel rated for 150 & 300 psig to 500°F.
