Single Flanged Expansion Joint

The single flanged metallic expansion joint was manufactured from 304 stainless steel bellows with carbon steel flanges. It has a diameter of 20″ and an overall length of 15″. It will be used in an exhaust duct application in a power plant. A hydro-test was performed prior to shipping to Orlando, Florida.

U.S. Bellows, Inc., a subsidiary of PT&P, has recently supplied four 72-inch expansion joints required for the piping system of a power plant being built in Zhuhai, China. These large expansion joints will carry the exhaust from the plant’s boiler feed pump turbines.
