Metal Bellows and Expansion Joints Manufactured for Excellence


PRESSURE BALANCED BELLOWS EXPANSION JOINTThe pressure thrust imposed on the system piping anchors
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. Let our design engineers help you determine the right expansion joint for your piping system.

Tied Universal Metal Bellows Expansion JointsThe Tied Universal Expansion Joint design has large
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. The universal expansion joint can be used in a wide variety of applications from engine exhaust piping systems, steam piping and even for seismic isolation. The design team at Triad Bellows Design and Manufacturing is always ready to assist with your next project.
