Elbow pressure balanced expansion joint is a type of pressure balanced expansion joints which are used in the piping system and where the pressure thrust is required or changing the direction of the flow needed to be changed. It is also known as corner relief expansion joints.

Manufacturing this type of pipe expansion joint bellow is really a combination of several metal expansion jointtypes. The objective is to maintain and stabilize the pressure thrust so that main anchoring of the pipe or alongside equipment is not needed, forces and movements on attachment flanges of a gentle machine, like turbines, are kept to acceptably low levels. The deflections to be accepted are controlled by the proper type of flexible pipe expansion joint, which normally is a tied universal joint type to accept lateral movements. However, the pressure balanced elbow joint 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.

• Simple to manufacture
• Stable at high pressures
• Absorbs small amounts of axial and lateral movement
• Eliminates change in pressure
• No main anchors required
• Conserves space

This balancing stainless steel bellow is joined 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 segment of the flexible 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 pattern, however, the spring rate of the entire expansion joint is the sum of the spring rates of the balancing and the universal expansion joints bellows. This is a fixed 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 essentially always a singular bellow.

Pliant bellows provide high-quality elbow pressure balanced expansion joints dealer, and always supply flexible bellows at best rate.
