Figure: 670 - 678
Designed for use with insulated or non-insulated pipe lines to direct the axial expansion and contraction of the pipe. The use of two or more guides on both sides of the expansion joint is recommended to avoid a pivoting effect. The first pipe guide should be placed a maximum of 4 pipe diameters from an expansion joint. Pipe guides are not designed to support any of the piping system’s weight therefore additional supports are required. The maximum operating temperature should not exceed 750°F (399° C).
Designed to be welded directly to the pipe to allow for support from below and allow for horizontal movement with a low coefficient of friction. The assembly consists of a carbon steel tee with a polished stainless bottom which rests on a PTFE (glass filled teflon) plate, bonded to a carbon steel plate. The base plate configuration will vary with the Type selected.
