 Pipe Expansion Joint Design & Manufacturing
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.
