December 9th, 2012 Comments off

U.S. Bellows, Inc. fabricated this 28″ dia., 109″ long universal expansion joint with 1″ thick AA-22 abrasion resistant refractory lining and pantographic linkage for a FCC unit in an oil refinery. The entire assembly is fabricated from 304H stainless steel with carbon steel pantographs. This expansion joint has two-ply testable bellows with wire mesh strip between the plies. It is designed for an axial movement of 5″, a lateral movement of 5-1/2″ at 1425°F and 45 psig. This unit was 100% dye penetrant tested, all pressure retaining welds were 100% radiographed and the unit was pneumatic tested prior to shipping to Oklahoma.
