Expansion Joints

Universal Expansion Joint -- Hinged / Gimbal SS321

Universal expansion joints with two sets of SS321 bellows connected by a centre pipe and restrained by hinge or gimbal hardware that absorbs large angular movements in single or multiple planes. Hinge restraints allow angular movement in one plane only, while gimbal hardware permits angular movement in any plane. Tie rods absorb pressure thrust, eliminating the need for main anchors. Ideal for high-temperature steam headers, turbine exhaust ducting, and complex piping layouts with multiple direction changes.
