31" I.D. Custom Turbine Expansion Joint

A custom fabricated 31″ I.D. turbine expansion joint was designed and fabricated to be placed in service for a company in Texas. The expansion joint unit was reverse engineered, from the previous unit, with improvements to the current design. It is fabricated from 321 stainless steel with Inconel 625 bellows. The turbine expansion joint is 36″ long and is designed for 70 PSIG at 450 deg. F and axial travel of 4″. The expansion joint was 100% dye-penetrant examined and hydro-tested prior to being shipped to the customer.

Custom Thick Wall Flanged and Flued Head Expansion Joints for Heat Exchangers in California

Various sizes of thick wall flanged and flued head expansion joints were custom designed for heat exchangers in California. Two are 30″ in diameter and two are 18″ in diameter. They were designed for 1″ axial extension and 14 psig at 300°F. All four expansion joints were fabricated from ASTM A-516 Gr. 70 carbon steel material. A dye penetrant exam was conducted prior to shipping.

14 Single Reinforced Metal Expansion Joints for a Construction Company in Israel

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 hydrotested to 205 PSIG for quality and performance assurance.
