Elbow Pressure Balanced Expansion Joint

We are instrumental in providing Elbow Pressure Balanced Expansion Joint which is really a combination of several types. Its purpose is to retain and balance the pressure thrust so that main anchoring of the pipe or adjacent equipment is not required, and forces and movements on attachment flanges of delicate equipment, such as turbines, are kept to acceptably low levels.

Briefly, the deflections to be accepted are handled by the proper type of expansion joint, which normally, and as shown in the above sketch, is a tied universal type to accept lateral movements. However, the pressure balanced elbow is usually required because axial deflections are also present. In order to accept these movements, a bellows is added beyond the elbow with the same cross-sectional area as the ones in the universal section.
Widely appreciated by our clients, these Elbow Pressure Balanced Expansion Joints are available at most reasonable prices.
