Type MPB-I
Product information
A pressure-relieved expansion joint is capable of absorbing axial and lateral movement, while at the same time neutralising the forces due to pressure. This is achieved by incorporating an additional bellows into the unit. It works in the opposite direction to the primary bellows and provides a force that ensures that no compressive forces are generated at the ends.
The Type MPB-I (in-line pressure balanced) is installed in a straight pipe system without change of direction.
The pressure-relieved expansion joints are installed in similar piping systems to the lateral and axial expansion joints with the great advantage that they do not transmit forces due to pressure to turbines or other sensitive equipment. The only force to be considered is the adjustment force to move the bellows.
