This 42″ dia., 118″ long universal expansion joint was designed with pantographic linkage and slotted hinges for flue gas application in a Columbian refinery. The redundant two-ply testable bellows are fabricated from Inconel 625 LCF and the remainder of the assembly was fabricated with refractory lined carbon steel. It is designed for an axial movement of 1.3″ at 1,000°F and 50 PSIG. All welds were 100% dye penetrant examined, the bellows longitudinal seam and pipe seams were 100% X-ray examined. The complete assembly was pneumatically tested to 50 PSIG.
