Gimbal Expansion Joint

The gimbal type corrugated expansion joint is a flexible part composed of a corrugated pipe, a balance ring and two pairs of hinge plates connected with the balance ring and the end pipe. Generally, two universal hinge types or two universal hinge types are used together with a single hinge. It is suitable for "L" type and "Z" type piping systems. It mainly compensates for multi-plane bending by angular deflection. Composite displacement of the pipe segment. Since the balance ring, pin shaft and hinge plate can withstand the action of pressure thrust and other additional external forces, the expansion joint itself absorbs the internal pressure thrust and will not generate external force on the pipeline, so the setting of the pipeline support can be simplified. In order to ensure that the customer's products will be free from defects in the future, the thickness of the hinge plates and gimbal rings of all universal hinge products manufactured by our company absolutely meets the safety requirements to ensure that they can withstand the major pipeline pressure and thrust caused by the future work process.

The gimbal expansion joint realizes the angular displacement of the pipeline in any plane through the action of a universal shaft and a pin shaft. The pin can also function as a limit to a certain extent to avoid damage to the bellows. And the structure is reasonable and the operation is stable, which greatly reduces the later maintenance of the pipeline. The universal joint compensator mainly compensates the synthetic displacement of the multi-planar curved pipe section in the way of angular deflection. Because the balance ring, pin shaft and hinge plate can withstand the action of pressure thrust and other additional external forces, absorb the internal pressure thrust by themselves, and will not generate external force on the pipeline, so the setting of pipeline support can be simplified. Universal hinged corrugated compensator can compensate for any upward angular displacement of the pipeline. The difference between the universal hinge type compensator and the hinge type is that it has a universal ring, and there are two pairs of mutually perpendicular hinge structures in the circumferential direction of the universal ring, so it can absorb the angular displacement of any plane, and also absorb the lateral displacement. Two or three combinations are required.
