U.S. Bellows, Inc. provided rubber expansion joints for an 8″ pipeline. This single open arch rubber expansion joint is fabricated from EPDM rubber and the retaining rings are galvanized A36 carbon steel and powder coated orange. The expansion joints were designed for an operating pressure of 250 psig with a 30″ vacuum, 1.75″ compression, 0.88″ extension, and 1″ lateral offset. Rubber pipe expansion joints are often used to compensate for minor misalignment and offset. Each unit was hydro-tested at 250°F at 75 psig. An advantage of a rubber expansion joint (also called an elastomer joint) over the metallic is the ability to prevent the transmission of vibration and to do this without significant harm to the joint. They can be utilized for pump inlets and discharges solely to stop vibration and noise from the pump. They have an integrally flanged design where no gaskets are required. Metal reinforcing rings can also be added to help resist pressure and flexing during operation. Fabric reinforcement within the rubber can also be added for applications to take the load of fluid pressure. At U.S. Bellows, our engineers are professionally trained and qualified to both design and manufacture units specifically for your application per expansion joint manufacturing association (EJMA).
