This pressure balanced tee expansion joint was custom designed for a boiler feed pump turbine exhaust in a power plant. It is 96" Dia. x 288" OAL and fabricated from carbon steel with 304 stainless steel bellows, turning vanes and liners. It is designed for 2" axial movement at 315°F and 15 psig. 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 performed a pneumatic test at 23 psig.
