Axial metal bellows
An axial metal bellows uses a metallic bellows element to accommodate length change along the pipe axis. The title establishes no movement amount, cycle life, bellows material, or restraint arrangement, and torsion should not be imposed. Pressure, temperature, movement, spring rate, anchors, and guides require coordinated design.
Application and duty
Axial pipe-movement accommodation within an engineered anchors-and-guides system
