Product Description

Pressure balanced bellows expansion joint is a special type of compensator designed to compensate for axial displacement in a system while balancing internal pressure thrust, ensuring the safe operation of pipeline systems. This compensator effectively absorbs axial deformation through its special structure and mechanism, while achieving balance of internal and external pressure through internal structural adjustment, thereby reducing impact on pipeline systems and other connecting equipment.
