U.S. Bellows custom designed 8 of these 335″ long universal expansion joints for a vacuum ducting service, exposed to high velocity steam and condensate for an ACC unit in New York. The bellows were completely fabricated from 304 stainless steel, with the weld-ends and hardware from carbon steel. The units are 127″ in diameter and 335″ in length. They are designed for an operating pressure at full vacuum to 15 psi at -10 to 250°F and 7.25″ of lateral deflection. The units were vacuum tested at 28.5″ of mercury, 100% dye-penetrant examined, and X-ray long seam bellows.
