U.S. Bellows, Inc. designed and fabricated two 78″ I.D. x 110″ O.D. and two 36″ I.D. x 68″ O.D. thick wall flanged and flued head expansion joints. All four expansion joints were fabricated from 1/4″ thick ASTM A516 grade 70 carbon steel plate. The expansion joints were cold-formed and heat-treated to customer requirements. The external surface of the expansion joint was painted with one coat of shop primer. The weld ends of the expansion joint are beveled, and drainage plugs are installed in the crest of the bellows. The bellows long weld seams were 100% dye-penetrant and 100% x-ray tested. U.S. Bellows provides 100% customer satisfaction in terms of quality and delivery.
