62" Fabric, 42" Hinged and 42" Tied Universal Expansion Joints and Duct Work Designed for an Acid Plant

U.S. Bellows custom designed two 42″ tied universal expansion joints, a 42″ hinged expansion joint and a 62″ fabric expansion joint in ductwork for an acid plant in Louisiana. The assemblies had flanged and flued head bellows fabricated from 304H stainless steel. The rest of the assemblies were made from carbon steel with operating temperatures of 700°F at 10 psig. The expansion joints were dye penetrant and x-ray tested prior to shipment.

54" Dia. Refurbished Custom Crossover Expansion Joint

U.S. Bellows refurbished a 54″ dia. custom crossover expansion joint for a power plant in Kansas. The flow end and balancing end bellows were replaced. The pressure balanced expansion joint was designed for 1″ axial movement at 700°F and 150 psig. The bellows longitudinal weld seams were 100% x-rayed and the assembly was hydro-tested at 180 psig prior to shipment. The refurbishment was completed in three weeks to meet the customer’s outage requirements.

One of U.S. Bellows’ customer’s existing expansion joint failed and caused a plant shut down. They required an immediate replacement joint. This universal expansion joint order was placed, designed and fabricated in just one day. The order came in at 8:30 am on Saturday, Labor Day weekend and was shipped at 4:00 pm, which minimized the time of the plant shut down. This universal expansion joint is 96″ in overall length, 20″ inside diameter and can absorb 3.25″ lateral movement. A 100% dye-penetration test and a hydro-test were performed to ensure quality.

Within a three day span, U.S. Bellows, Inc., fabricated a 40″ I.D., single coded, clam shell expansion joint for a chemical plant in Beaumont, Texas. The chemical company utilized U.S. Bellows’ 24 x 7 Quick Turn/Emergency service. After the representative from the chemical plant completed the online form, the U.S Bellows’ on-call team was immediately paged. Three days later the bellows had been successfully fabricated, welded to an A516-70 heat exchanger shell and shipped to the chemical plant to resume operation. The bellows was fabricated from A240 tp 321 SS and designed at 50 PSIG and 750°F. In order to detect any leaks in the weld, the bellow’s long seam weld was 100% x-rayed and its attachment weld was 100% dye-penetrant.
