This rectangular metallic expansion joint measures 22″ x 84″ x 11″ face-to-face and is fabricated from 316 stainless steel bellows and carbon steel flanges. This expansion joint is designed to absorb axial compression in a hot air duct system to a fan inlet. The bellows have three convolutions with mitered corners. The expansion joint was 100% dye-penetrant examined and soap and air tested prior to being shipped to a power plant.
