Performance characteristics of external pressure corrugated pipe expansion joints:
The external pressure corrugated pipe expansion joint is composed of an inner cylinder, a corrugated pipe, an outer cylinder, and auxiliary components. Bellows are subjected to external pressure, have good sealing and bending resistance, and can absorb large displacement. It can be made into single, double, bidirectional and other forms. The axial outward pressure bellows expansion joint mainly absorbs axial displacement and has advantages such as large compensation, good insulation performance, and reduced residual medium.
The pressure and thrust of the external pressure bellows expansion joint are due to the force generated by the pressure applied to the bellows. This force is obtained by multiplying the system pressure by the corrugated pipe area. If there is no expansion joint, the pipeline system will be affected by pressure, and the system will not move due to the fact that the pipeline and tension are in the opposite direction. When an unconstrained expansion joint is applied to a pipeline system, the force in the pipeline will be absorbed by the expansion joint without affecting the pipeline system itself. This pressure and thrust includes the main fixed bracket or controlled expansion joint to withstand the load of pressure and thrust. This main fixed bracket can withstand pressure thrust and a small amount of force caused by the deviation of the corrugated pipe.
