This elbow pressure balanced expansion joint was designed for a chemical processing plant to aid the nitrogen oxide process for compound fertilizers. It is 18″ diameter with a face of weld-end to centerline of elbow length of 83- 3/8″. The body of the assembly, the pipe, covers and tie-rods were fabricated from 304L stainless steel, the bellows and liners from 321 stainless. This unit was designed for 1/2″ compression and 4-1/8″ lateral movement with an operating temperature of 600°F at 125 psig. The assembly was dye penetrant tested and hydro-tested at 190 psig prior to shipment.
