These single reinforced expansion joints with equalizing rings are used in heat exchangers. The bellows are fabricated from ASTM B 443 Inconel 625 LCF. The weld ends and the reinforcing rings/root rings are carbon steel. The expansion joints are 52” and 57” diameter with an overall length of 15 ½” and 16 ½”. They are capable of moving 0.6” in extension at 158 PSIG at 300°F. The expansion joints were fabricated to ASME Section VIII. The bellows and pipe longitudinal weld seams were 100% X-Rayed. In addition, the expansion joints were 100% dye-penetrate examined and hydro tested to 205 PSIG for quality and performance assurance.
