The corrugated expansion joint is used for the connection between the equipment and the equipment, its role is to compensate for the thermal expansion of the pipeline between the two equipments, to reduce the installation error on the equipment generated by the force, easy to install. The use of bending force-balanced corrugated expansion joints save energy so that the equipment is not subject to internal pressure generated by the role of the blind force, improve the stress condition of the equipment, equipment is easy to fix.
The corrugated expansion joint is used as a soft coupling pipe for pumps in the inlet and outlet pipelines of pumps. In the pump inlet and outlet pipe installed on the universal (i.e., universal) expansion joints to compensate for thermal expansion of the pipeline, reduce the thermal expansion of the pipeline on the pump thrust, or absorb the vibration generated by the pump operation.
