Good sealing performance

Special sealing structure, the gland presses the wedge-shaped sealing ring to ensure good sealing effect when compensating for the displacement of the pipeline within the expansion range

Adjustment function

It can accurately control the flow of the medium in the pipeline to achieve the functions of fluid guidance, cutoff, throttling, check, diversion or overflow pressure relief

Limiting function

The double flange limit expansion joint can effectively limit the displacement of the pipeline by setting a limit device to ensure the stability and safety of the pipeline system

Expansion function

The double flange limit expansion joint can freely expand and contract with the expansion and contraction of the pipeline. This expansion function effectively reduces the stress of the pipeline, thereby extending the service life of the pipeline and improving its performance
