The article discusses methods provided by grooved mechanical pipe-joining systems which allow various types of piping movements caused by thermal expansion and contraction. Thermal movement is considered when a pipe expands when heated. The four methods to accommodate thermal movement are the utilization of flexible grooved couplings for linear movement and deflection, provision of expansion joint, provision of expansion loop, and the application of free-floating system.
