Bend Pressure Balanced Bellows Expansion Joint, this type of expansion joint 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. 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.  Â
This balancing bellows is connected by the tie rods to the pipe
beyond the universal section; in this way the pressure thrust is
contained as tension in the tie rods. The section of the expansion
joint between the tie rods, which includes the elbow, is now free
to move axially, with the only resistance being a function of the
spring rates of the bellows. Because of their arrangement, however,
the spring rate of the entire expansion joint is the sum of the
spring rates of the balancing and the universal bellows. This is a
constant volume system, in that when the universal end compresses,
the balancing end extends the same amount. All of the lateral
deflection is absorbed by the universal end, and there is no
lateral deflection imposed on the balancing end. Therefore, the
balancing bellows is almost always a single bellows type.
1. Absorbs axial and lateral movements
2. Eliminates main anchors
3. Minimum guiding required
4. Pressure forces remain in balance
5. No volume change
6. Balance pressure thrust remains constant
