Triad Expansion Joints: Ready to Install

A Metal Bellows Expansion Joint is created when fittings are welded to a formed Metal Bellows. Depending on your requirement, the connection to your existing piping system can be joined by standard pipe weld ends, standard ANSI B16.5 (150#, 300#, and 600#) flanges, or by custom made, alloy specific flanges.
