U.S Bellows, Inc, the expansion joint division of Piping Technology & Products, Inc., recently designed and fabricated three elbow pressure balanced expansion joints for a power station in Canada. These joints are designed at 150 PSIG and 450ºF to allow lateral and axial movements in a 42″ steam line. Expansion joints were designed and fabricated per EJMA and B31.1 code. The expansion joints were hydro-tested at 225 PSIG and 75ºF. In order to detect any leaks in the weld, prior to and following forming, bellows long seam welds and attachment welds were 100% dye-penetrant tested.
