Metal bellows expansion joints are designed to compensate for thermal movement of piping systems and take up far less space than piping bends and expansion loops require.
Custom-engineered single- and dual-bellows designs are made from 18-8 stainless steel alloy 321 as well as special alloys including Monel, Inconel, and Hastelloy. Options for metal expansion joints include PTFE-lined, universally-tied, in-line pressure-balanced, externally-pressurized, Gimbal, and hinged, among other configurations.
With a wide range of metals, Kadant Unaflex metal bellows expansion joints can be designed to operate up to 300 psi and with temperatures up to 1,500°F in sizes from 2” up to 144”.
