U.S. Bellows customized single-ply X-Flex bellows for the world’s largest manufacturer and supplier of flooring products with locations throughout the U.S. Flooring products such as carpet, ceramic tile, natural stone, laminate, vinyl, and hardwood require many of the same piping systems as traditional indoor plants for the automotive, food processing, semiconductor, textile, and pulp & paper industries. Plants that manufacture flooring are usually quite large requiring large tracks of land. As a result, the “pipe runs” can extend hundreds of feet requiring various types of expansion joints to accommodate the movement of the pipe while also relieving stresses in the piping system. Externally pressurized expansion joints are especially suited for piping systems that require large amounts of axial compression or extension. In externally pressurized pipe expansion joints, the bellows elements are arranged so that the media flow is on the external surface of the bellows. Externally pressurizing the bellows eliminates pressure instability as a limitation to the design and permits the absorption of large amounts of axial expansion. These expansion joints are fabricated with 304 stainless steel bellows, flanges, and pipe. They are designed for 300°F at 14.7 psig with an 8″ extension. The units are 3″ pipe x 40″ long, and 4″ pipe x 40″ long. The expansion joints were hydro-tested and underwent NDE quality control inspection tests such as liquid penetrate inspection (LPI) before shipment.

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.
