The toroidal shape gives the bellow the unique ability to carry high pressures; conversely, it also permits modest deflection ability. The expansion joint was designed for 400 PSIG at 500° F and an extension stroke of 5/16″ and the bellow’s element was fabricated from .060″ Inconel® 600 with A-516 gr 70 weld ends. The 92-inch toroidal expansion joint was also designed per ASME Sec. VIII rules as well as the Expansion Joint Manufacturer EJMA Standards. Upon fabrication completion, a hydro test was conducted at 600 PSIG to detect leaks.
