In-line Pressure Balanced Pipe Expansion Joint
When axial deflections exist, and anchoring is impractical for structural or economic reasons, such as high in the air or short straight pipe runs between two large vessels, the in-line pressure balanced pipe expansion joint is a powerful solution to a difficult design problem. The principle of this type of unit is essentially the same as the pressure balanced elbow type, in that the axial pressure thrust is reacted by the pressure acting on a cross-sectional area equal to the area of the working or primary bellows.

- Simple to manufacture
- Stable at high pressures
- Absorbs small amounts of axial and lateral movement
- Eliminates change in pressure
- No main anchors required
- Conserves space
