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.

Expansion Joint Application and Design
Our Expansion Joint course was developed for the following disciplines…
- Piping system designers that may decide to use expansion joints
- Expansion joint designers use the information provided by piping system designers to determine the best design to meet the requirements.
- Designers that use modern software systems to evaluate different options
- Engineers / Managers: field, maintenance, process, operations, construction, surveyors
