The externally pressurized expansion joints are 37.5" in diameter and 36" face-to-face. The bellows are 304 stainless steel, and the flange and ring are carbon steel. This expansion joint is rated for 232 psig with 5" axial compression and temperatures up to 189°F. All bellows longitudinal welds were 100% x-rayed, all carbon steel welds were dye penetrant examined and each unit was hydro-tested to 348 psig. A total of 56 units were fabricated for a cooling system in a new university for women in the middle east.
