Product description
The principle of this type of unit is essentially the same as the pressure balanced elbow type, in that the axial pressure thrust is reacted by the pressure acting on a cross-sectional area equal to the area of the working or primary bellows.
Advabtages
This type of expansion joints consist of two working bellows located at the ends, one balanced bellow located in the middle, tie rod, the end plate and some other components. The effective area of balanced bellows is twice of the working bellows. So the lateral axial thrust caused by working bellows’ Internal Pressure is canceled out by another thrust coming from the opposite direction caused by the balanced bellows’ Internal Pressure through the tie rod. Therefore the axial thrust doesn’t output, which means the piping and the equipment only carry the rigid counter-force caused by the movements of expansion joints instead of the axial thrust caused by Internal Pressure. Compared with the blinding plate force, rigid counter-force is dozens of times smaller. So fixing the equipment and pipes becomes easier and available. But this type of expansion joints can only absorb axial movements.

Application in corrugated expansion joint equipment
The bending force balance type bellows expansion joint is used for the connection between equipment and equipment. Its function is to compensate the thermal expansion of the pipeline between the two equipment, reduce the force generated by the installation error on the equipment, and facilitate the installation.It adopts the bending force balance-type corrugated expansion energy-saving to make the equipment not affected by the blind plate force caused by the internal pressure, which improves the force condition of the equipment and makes the equipment easy to fix.Corrugated expansion joints are used as pump couplings on pump inlet and outlet pipes.A universal (ie universal) expansion joint installed on the pump's inlet and outlet pipelines to compensate for the thermal expansion of the pipeline, reduce the thrust of the pipeline's thermal expansion on the pump, or absorb the vibration generated by the pump operation.
