These rectangular metal bellows are fabricated entirely from ASTM A-240 type 304 stainless steel. The larger bellows measures 240″ x 80″. The smaller bellows measures 157″ x 65″. The design conditions were 1 PSIG at 1,000°F. Both metal bellows are designed with three convolutions with round corners. The metal bellows welds were 100% dye-penetrant examined and soap and air tested prior to shipment. These bellows are designed to be installed at the ductwork connection to a large steam boiler.
