U.S. Bellows, Inc. refurbished a rectangular metal expansion joint on an emergency basis for a local chemical plant. Upon arrival, the expansion joint was acid washed and dye-penetrant examined for any cracks in the metal. The expansion joint bellows were then repaired, retested and sent back to the customer in a matter of two days. The expansion joint measures 21″ x 26″ x 36-3/8″. The bellows are fabricated from Inconel® 625 LCF material. The rest of the assembly is fabricated from Inconel® 600 material. The design temperature is 660°F and the design pressure is 20 PSIG. The expansion joint was soap-air bubble tested and dye-penetrant examined before being returned.
