This 42″ dia. x 13-3/4″ OAL single expansion joint was refurbished for a chemical plant. The bellows were replaced with 304 stainless steel and the flanges were sand blasted and painted. The expansion joint was designed for a spring rate of 4,253 lb./in., 5/8″ axial movement at 222°F and 50 psig. A dye penetrant examination and air soap and bubble test was conducted prior to shipping.

Listen to in-depth explanations on how to choose the type of expansion joint that will best suit your system. Learn about the bellows movements throughout the piping system due to thermal changes of mechanical motion. Increase your understanding of the different types of expansion joints and value-added services offered by U.S. Bellows.
U.S. Bellows, Inc., a division of PT&P, has more than 50 years of experience designing and manufacturing expansion joints, along with replacement and repair services.
This elbow pressure balanced expansion joint was designed for a chemical processing plant to aid the nitrogen oxide process for compound fertilizers. It is 18″ diameter with a face of weld-end to centerline of elbow length of 83- 3/8″. The body of the assembly, the pipe, covers and tie-rods were fabricated from 304L stainless steel, the bellows and liners from 321 stainless. This unit was designed for 1/2″ compression and 4-1/8″ lateral movement with an operating temperature of 600°F at 125 psig. The assembly was dye penetrant tested and hydro-tested at 190 psig prior to shipment.

This webinar was created to explain the basic principles of expansion joints in the simplest way possible. The presentation will introduce you to expansion joints and concentrate on metallic and fabric expansion joints. It will explain the various designs, applications and details of each expansion joint using simple terms and a lot of visual aids. The presentation will conclude with general guidelines of the maintenance and ordering process.
This 153″ x 55″ x 21″ fabric expansion joint was custom designed for an exhaust application in a gas turbine facility overseas. It is fabricated from carbon steel with a painted frame and liner. The fabric belt is reinforced neoprene, and it’s designed for +/- 100″ water column with a temperature of -20°F to 600°F. A dye penetrant examination and paint thickness test was conducted on the assembly before being shipped.
U.S. Bellows designed and manufactured this universal expansion joint in accordance with ASME section VIII for an oil and gas refinery in Europe. A U2A- form was furnished as part of the units’ documentation. The expansion joint has a 24″ diameter and 103″ overall length. The bellows, liners and covers are fabricated from 316 stainless steel, and the flanges, tie-rods and pipe are carbon steel. The unit is designed for an operating temperature of 181°F at 101 psig and 1″ axial movement with a 3″ lateral offset. The bellows and pipe longitudinal weld seams were x-rayed, dye-penetrant and hydro- tested prior to shipment.
These fabric expansion joints were custom designed for an exhaust duct in a gas turbine facility in Europe. The 81″ x 18″ x 16″ face to face expansion joints have a integral stainless steel frame and liner with a reinforced red silicone fabric belt. The assemblies were manufactured for a 400°F operating temperature at +/-100 inches of water column pressure. The expansion joints were 100% dye pen tested before being shipped to the customer.

This presentation will briefly touch on the basics of fabric expansion joints; however, is mainly focused on the various designs, material details, and applications. Learn how fabric expansion joints are engineered and fabricated for various applications and the many factors that influence those designs. View the abundance of materials used, including Fluoroplastic and Fluoroelastomer, and their respective capabilities. Take a journey through a Fossil Fired Power Plant and see exactly where fabric expansion joints are required.
This 60″ dia. x 20′ OAL elbow pressure balanced expansion joint was refurbished by U.S. Bellows in 3 weeks for a power generation plant in Wisconsin. The bellows are fabricated from Inconel 625 and the duct, elbow, cover and liner of carbon steel. The expansion joint was designed for 1″ axial movement at 715°F and 185 psig. The bellows longitudinal seams were 100% x-rayed prior to forming. After replacing the bellows, the expansion joint was dye penetrant tested and hydro tested at 185 psig.
This duct work and expansion joint assembly was custom designed by U.S. Bellows for an oil refinery in California. The project consists of 36″ x 48″ 304 stainless steel oval shaped duct work with a thick wall expansion joint and 30″ x 16″ carbon steel round shaped duct work. It is designed for 900°F at 13.2 psig, and the entire assembly was dye penetrant examined and 100% x-rayed prior to shipment.
