Type: Single Expansion Joints Size: 42″ ID | 24″Face-To-Face Material: Inconel 600 | 304 Stainless Steel | Carbon Steel Design: 350°F Operating Temp. @ 100 psig | 0.75″ Lateral Testing: Hydro-tested These single expansion joints were custom designed by U.S. Bellows for an exhaust duct application at a gas turbine facility in Indiana. The units have a 42” ID and are 27” face-to-face. The bellows were fabricated from Inconel 600, the liners from 304 stainless steel, and the cover, rods, and hardware from carbon steel with red oxide primer on all exposed carbon steel. They are designed for an operating temperature of 350°F at 100 psig, 0.625” of axial compression and 0.75” of lateral deflection. The expansion joints were hydro-tested prior to shipment
