Pressure Balanced Bellows Expansion Joint

PRESSURE BALANCED BELLOWS EXPANSION JOINT

The pressure thrust imposed on the system piping anchors is nearly eliminated with the pressure balanced expansion joint design. Triad Bellows designs and manufactures both the 90-degree elbow style (shown) and the inline pressure balanced style. When space limitations prevent sturdy enough anchor designs this metal expansion joint comes to the rescue.

Tied Universal Metal Bellows Expansion Joints

Tied Universal Metal Bellows Expansion Joints

The tied universal expansion joint design has large lateral offset capabilities. This double bellows style expansion joint can also be engineered for large amounts of axial compression or a combination of both. Tie rods are designed to absorb the full pressure thrust of the bellows eliminating the need for anchors when used for lateral offset only.
