US Bellows recently refurbished a 3″ O.A.L. single bellow with flanges for a marine vessel in Texas. Within a two-day span, the replacement bellows were fabricated, welded to the existing 5/8″ flanges, and shipped to the marine vessel to resume operation. The replacement bellows, fabricated from 321 stainless steel, was designed for 150 PSIG and 800° F with 0.66″ of axial movement. To ensure quality, a 100% dye-penetrant test and a soap leak test were performed prior to delivery.
