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...

Expansion Joints - Type MRR | Macoga

This model is used in cases of high internal pressures and/or equalizing the movement among all the corrugations. The system involves the use of reinforcement or equalizing rings located around the outside of the convolution thus preventing the bellows being forced out of shape due to the high pressures. Equalizing and Reinforcing Rings are devices used...

Expansion Joints - Type MPBI Inline pressure balanced | Macoga

A pressure balanced expansion joint accommodates axial and lateral movements and counteracts the bellows pressure thrust. An additional bellows is incorporated into the unit and is subject to the line pressure to generate a force equal and opposite to that on the main bellows. Tying these bellows together neutralises the pressure load on the unit. The...
