Ceramic lined pipe expansion joints are designed to safely absorb the dimensional changes of pipework systems and ducts caused by heat induced expansion and contraction.
Metallic expansion joints are designed to safely absorb the dimensional changes of pipework systems and ducts caused by heat induced expansion and contraction. They are essential in pipework systems that are used to convey substances of a high temperature, such as steam, heated water or exhaust gases.
Expansion joints can also be designed for other applications, such as noise and vibration caused by reciprocating machinery, building settlement and in some extreme environments earthquake movement. Expansion joints are very important components with in a pipework system as they not only solve the problems associated with pipework movement but offer such advantages as reducing stresses and loads to connecting equipment such as pumps and steam turbines.
