It is divided into single bypass pressure balanced bellows expansion joint and compound bypass pressure balanced bellows expansion joint. The bellows of the same specification are used, with small volume, low cost, good guidance and good stability. It is mainly used to absorb the axial displacement and balance the pressure and thrust of the bellows. The internal pressure and thrust load is balanced and borne by its own components. It is used in the occasions where large thrust is not allowed. |
It is mainly used in the occasions where there is no need to set a fixed support, which can effectively protect the equipment and pipelines from deformation. |
