U.S. Bellows, Inc. designed and fabricated this refractory lined universal expansion joint for an FFC Unit in India. This is a 70″, outside diameter, tied refractory-lined universal expansion joint with two-ply Inconel® 625 LCF bellows, A516 weld ends and spool, and a 4″ thick refractory lining per UOP specifications. This joint was designed at 51 PSIG and 1400 degrees F. Bellows long seam welds were 100% x-rayed and 100% dye-penetrant before and after forming. It was also pneumatic tested at 57 PSIG the refractory lining was dried out per UOP specifications.
