U.S. Bellows, Inc. custom-designed a pressure balanced tee universal expansion joint for a boiler feed pump turbine exhaust. The expansion joint is 96” diameter and 288” OAL and is designed for 2″ axial movement at 315°F and 15 psig. The bellows, liner, and turning vanes are 304 stainless steel. The remainder of the assembly is fabricated from carbon steel. The expansion joint was dye penetrant examined, and a chemical cleaning of the interior surfaces was performed to remove any oil and grease. U.S. Bellows also conducted a stress analysis and a pneumatic test at 23 psig.
