sanitary sewer UV CIPP Lining underground pipe trenchless repair DN200-1650

UV CIPP cure liner for underground pipe sewer trenchless repair from DN200-1650

DAO UV cure liner is designed for underground pipeline sewer trenchless repair using CIPP technology. It is good to use LED cure system or High voltage Mercury lamp cure system.

Glass fiber composite felt, plastic film, resin, defoamer, coupling agent, curing agent, thickener and knife scraping cloth as raw materials, the UV cure liner is produced through the processes of discharging, folding, coating, receiving, mixing, pouring glue, rolling, wrapping knife scraping cloth, receiving and packing, placing auxiliary materials and so on.

UV cure liner material

1. The repaired pipeline structure meets or exceeds the strength, stability, and deformation requirements

2. After repair, the pipeline is smooth and meets the requirements of overcurrent capacity

3. The service life of the repaired pipeline is more than 50 years

4. Good ductility and fit the pipe wall

5. The material has good stability. If the curing is interrupted in the middle, it will not affect the curing effect if it is restarted.

6. High performance compared with other materials

7. Compared with imported materials, the curing speed is fast 2m/min.
