Pressure balanced type metal joints

Metal expansion joints
Pressure balanced type metal joints


Construction: A pressure balanced design uses an additional bellows to provide an equal and opposite reaction force to the pressure thrust; typically used to allow axial movement but not subject the piping system to the pressure thrust force.

Selection Criteria: A pressure balanced joint is used when other expansion solutions cannot be employed.

Main applications: Power plants, Refineries – inlet and outlet to turbo machinery.
