Description
The HMP™ Expansion joint is a custom designed piece of equipment that is designed to allow for contraction and expansion in vertical, inclined and horizontal installed piping.
There are two types of HMP™ Expansion joints, the first with jacking bolt arrangement. The jacking bolt arrangement simplifies installation and prevents the expansion joint from pulling apart. The second type has no jacking bolt arrangement. Should this type of expansion joint be used, extra care needs to be taken in the design of the piping system in order to prevent to expansion joint from pulling apart. The HMP™ Expansion joint can be produced in a double acting expansion joint with an anchor point in the middle.
