Expansion Joints - Type Two Ply | Macoga

The bellows, as the most critical part of the Expansion Joint, can be single ply, multiply, redundant ply or reinforced. In two ply testable bellows each ply is designed for the full operating conditions (pressure, temperature and movements). If a hole or stress crack develops in the inner ply during service, the outer ply takes over without exposing...

Expansion Joints - Type MWC | Macoga

Gimbal Expansion Joints are designed to allow angular movement in any plane by the use of two pairs of hinges affixed to a common floating gimbal ring. The gimbal ring, hinged and pins are designed to restrain the pressure thrust due to internal pressure and shear forces. A gimbal ring is either round or square. For round gimbals the torsional moment...
