Construction Method and Product Performance of CPVC Power Pipe

CPVC power pipe introduction 1. Construction method (1) CPVC power pipe pipe laying installation CPVC power casing standard length is 6 meters, each pipe needs to be equipped with 3 pipe pillows, pipe pillow spacing is set to 2.0m, pipe pillow from the joint distance is 0.5m. CPVC power sheath tube under the tube operation can be done manually, ground personnel will transfer the pipe to the bottom of the groove construction personnel, it is strictly forbidden to roll the pipe from the edge of the groove into the groove. If you need to adjust the length of CPVC power sheath tube, you can use mechanical tools to cut. The cutting incision should be perpendicular to the axis of the pipe pillow, and the incision should be smooth and flat. (2) CPVC power sheath tube connection CPVC power sheath tube connection method using socket or interface connection. The surface of the CPVC power jacket is marked with a mark of the insertion length. After the pipe is inserted into the socket, it is necessary to confirm whether the insertion mark is accurate and in place. Before the connection of the CPVC power jacket, the soil or other attachments on the outside of the pipe socket and the inside of the rubber ring should be removed to facilitate the connection and prevent water leakage. (3) Backfill soil Trench compounding should be carried out in time after the acceptance of the pipeline concealed engineering to avoid losses caused by long-term exposure of the pipeline. The compactness of the backfill around the CPVC power jacket must meet the design requirements. The backfill should be filled into the groove manually, and mechanical backfill is strictly prohibited. The quality of the backfill must meet the compactness requirements specified in the design. 2.
