Product Description

Balanced Expansion Joint

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.
