Universal hinge compensator

In order to reduce the self-excitation of medium, the axial compensator has an inner sleeve in the product, which limits the radial compensation ability to a great extent. Therefore, it is generally only used to absorb or compensate the axial displacement of the pipeline (if a small amount of radial displacement is needed in the pipeline system, it can also absorb the groups of axial, angular and arbitrary displacements). Hinge compensator (also known as angular compensator), which is used in combination with two or three compensators (single use of hinge compensator has no compensating capacity), is used to absorb transverse deformation in a single plane; universal hinge (angular) compensator, which is used in combination with two or three compensators, can absorb deformation in three-dimensional direction.
