Metal Bellows Expansion Joints
Custom-engineered single- and dual-bellows metal expansion joints for piping thermal movement, up to 300 psi and 1,500°F.
Description
Metal bellows expansion joints compensate for thermal movement of piping systems and take up far less space than piping bends and expansion loops. 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.
