These expansion joints were designed at 170 PSIG and 450 degrees F. to absorb lateral movements and tested per B31.3. They were made with Inconel® 625LCF bellows and A105 300 lb. RFSO flanges. The entire assembly was hydro-tested at 255 PSIG and held under pressure for four hours. In order to detect any leaks, each expansion joint and its welds were subjected to the dye penetrant-test and the X-ray test, each of which were 100%, prior to and following forming.
