U.S. Bellows, Inc. custom-designed thick wall flanged and flued head expansion joints for large diameter piping in a heat exchanger application. The expansion joints, including the liners, are fabricated from 316 stainless steel. The first unit is 60″ O.D. x 84″ O.D., the second unit is 36″ O.D. x 60″, and both units have a 1/4″ nominal thickness. They were designed for 4.4 psig at 210°F with a 122″ water column. A dye penetrant exam on the circumferential welds was conducted prior to shipping.
