A tied universal expansion joint was custom designed for service in an acid regeneration plant in Louisiana. It is 48″ in diameter, 141″ in overall length and designed for 1″ axial movement, 2-1/2″ lateral movement and .33° angular rotation. The expansion joint is fabricated with 310 stainless steel bellows, and 301 SS liner, duct, flanges, transition duct and covers. It was designed for 10 psig at 1150°F, and was dye penetrant examined, hydro-tested at 15 psig, and the bellows and pipe longitudinal weld seams were 100% x-rayed.
This 30 foot long tied universal thick wall expansion joint is fabricated from carbon steel with 316 stainless steel bellows. The bellows are fabricated from 1/4″ thick flanged and flued heads. It is designed for an axial movement rate of 1/2″ with a lateral movement rate of 1-13/16″. The expansion joint was 100% x-ray tested and air & soap bubble tested prior to shipping.
