Papua New Guinea Capping type limit loose sleeve retractor
Product Description
After the gland-type limit expansion device is installed on the pipeline, tighten the nut elastic sealing ring, and under the action of the nut gland, rely on the mutual slope, tightly press on the outer ring of the pipe for sealing and connection. When the temperature changes, the pipe can freely expand and contract in the middle of the joint. When the foundation sinks, the pipe can deflect and ensure that the seal has no leakage, thus achieving the purpose of automatic compensation.
The gland-type limit expansion device is based on the original loose sleeve expansion joint, and is equipped with components such as limit short pipes. The maximum expansion amount is locked by double nuts, which can absorb the axial displacement of the pipeline in the allowable direction and bear the pressure and thrust in the pipeline.
