Expansion Joints

U.S. Bellows, Inc. has been designing and manufacturing engineered pipe and duct expansion joints for the industry since 1960.

Engineering and designing is done per EJMA equations as well as per the latest revisions of the ASME B31.3, ASME B31.1, and ASME Section 8, Division 1. U.S. Bellows designs are performed using in-house developed design software and calculations further checked using hand calculations. U.S. Bellows also has full in-house finite element analysis capabilities and we often use this methodology to prove designs
