 Expansion Joint Engineering
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/PT&P designs are performed using
in-house developed design software and calculations further checked
using hand calculations. U.S. Bellows/PT&P also has full in-house
finite element analysis capabilities and we often use this
methodology to prove designs.
