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.

How Metal Bellows are Made

By | October 1st, 2016|

How Metal Bellows Are Made BELLOWS DESIGN Metal bellows and bellows expansion joints are placed in piping systems to absorb the thermal growth of the pipe. Each time the piping system heats up and cools down the bellows goes through 1 complete cycle.  The manufacturing of a metal bellows starts with the design process. The desired life cycle of the bellows or expansion joint must be determined in order to [...]
