Inline pressure balanced expansion joints are designed to absorb externally imposed axial movement without imposing the pressure loading on the system.
This is accomplished by using two bellows both at line pressure tied to gether and acting in opposite directions. while the joint balances out the pressure forces, the force required to move the joint itself is not balanced
Both the flows of bellows and balancing bellows must be compressed or elongated in operation and the combined axial spring force acts on the piping equipment.

These joints are usually installed at any change of direction. The complexity of the inline pressure balanced expansion joint makes it an expensive unit. It can be justified economically only those cases where the problems created by the pressure loading would be even more expensive
