The high pressure expansion joint above is a single four convolution SB-443 INCO 625LCF bellow with 3 equalizing rings, 2 neck bands, 1 internal liner and 2 weld ends all fabricated from SA-240 type 347 stainless steel. The equalizing rings enable the joint to withstand a maximum allowable pressure of 1,170 psig at 815°F. The equalizing rings allow the use of a thinner more compact and flexible bellow thereby saving space and increasing the expansion joint cycle life. This expansion joint is 14.25″ long with a calculated cycle life of 772 cycles.
