5. Repair of pipe lining

The whole process of pipeline lining repair is composite hose lining (Inserted, IH) trenchless repair technology, which is to line a high-pressure continuous composite hose into the original metal pipeline to form a "pipe-in-pipe" composite structure. Under working conditions, the hose is close to the metal pipe.

Features and applicability:

Corrosion resistance-Non-metallic corrosion resistance;

Self-pressure-Bare tube pressure 1.6 MPa, blasting pressure 4.8MPa;

construction fast-Construction speed 300-400 m/h;

Over elbow-One pass through R5D elbow (90 °);

wide caliber-Repair the pipeline DN50-DN1200;

Distance long-- According to the needs of the project, the maximum distance of one construction straight line is 5km.

Main applications: oil field high-pressure corrosion pipeline repair, municipal water supply pipeline renewal, thermal pipeline renewal, industrial and mining water supply pipeline repair, gas pipeline repair or boost transformation.
