The most efficient piping system is the shortest and most directly routed system, however materials expand and contract with thermal change. In piping systems, these dimensional changes exert stress on the piping system.

To abate the dimension changes in the piping system itself, as well as fixed points where the piping system connects to a wide range of equipment (i.e. dampers), the overall system must have flexibility “Engineered” into the overall design.

A practical and cost effective means of achieving flexibility in a piping design is through the application of expansion joints. Expansion joints provide an excellent solution for isolation of settlement, seismic deflection, mechanical vibration and sound attenuation transmission produced by a range of equipment.
