Inline Pressure Balance Expansion Joints (IPBEJ) absorb axial and lateral movement in piping systems without transferring pressure thrust loads to sensitive equipment like turbines or pumps. They consist of two bellows?a flow bellow and a balancing bellow?connected by tie rods to neutralize pressure forces, making them ideal when main anchors are not feasible.
Key Features and Description
Pressure Balancing: The joint uses a balance chamber to create a pressure thrust that opposes the force generated by the line pressure, eliminating pressure loading on connected equipment.
Structure: Typically designed with a large flow bellows (matches pipe diameter) and a larger balancing bellows connected to the same tie rods.
Movement: Engineered to handle large axial movements (thermal expansion/contraction) and small amounts of lateral movement.
Components: Components usually include bellows, pipe-ends, flanges, and tie rods.
