In accordance with EJMA standards, the proper installation of Anchors and Guides are essential to restraining your piping systems and ensuring your expansion joints and compensators will function properly, as designed. Main anchors are necessary at the end of each pipe run, with guides installed to prevent the line from bowing, buckling or becoming misaligned because of thermal expansion or internal pressures. Pipe hangers and rollers are not considered to be adequate as guides. The main anchors must restrain the ends of the pipe so that all expansion is directed into the compensator. The main anchors must also withstand the end thrust force of the internal pressure. This force is shown in the Thrust Force Data Table. Compensators should not be subjected to hydrostatic pressure tests beyond their rated working pressures. If a higher pressure test is required, the factory should be advised. The inside of all piping must be clean before installing and testing compensators. Before the pipe lines are hydrostatically tested, all anchors and pipe guides must be secured. The contractor installing sweat end type compensators is advised to use a soft solder. Excessive heat used to make the solder joint may have a detrimental effect on the compensator. Soldered joints should be washed thoroughly so as to neutralize or remove acids used in solder fluxes.
