Product Profile of Externally Pressurized Expansion Joint

Externally Pressurized Expansion Joint takes pressure from the outside of the bellows element rather than on the inside as in a conventional expansion joint. The Joint consists of a heavy outer pipe which contains the pressure and serves as a shroud to protect the bellows and also functions as pipe-guide. The Joint is easy to insulate and steam tracing can be used to maintain the temperature of the medium flowing through it. The Externally Pressurized Expansion Joint provides low turbulence to the flowing medium due to the fact that the internal surface of the pipeline itself works as the liner for this expansion joint.
