Necessary product for underground pipeline repair construction work of CIPP UV

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 flow 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 midway, the curing effect will not be affected if it is restarted
6. high-cost performance compared with imported materials
7. compared with imported materials, the curing speed is faster, up to 2m/min

Daoyunai Energy Saving Technology Limited has been committed to manufacturing trenchless CIPP UV cure systems with liners and CCTV inspection crawlers for underground pipelines to service customers all over the world.

The product range covers four series and more than 20 models in the underground pipeline trenchless repair industry:

1. UV curing and repair integrated system D919: LED lamp curing and high-voltage mercury lamp curing.

2. UV cure liner: from diameter DN200 up to DN1800

3. Hot water cure liner: impregnated liner to invert by water gravity and cure by hot water

4. Pipeline inspection robots crawler D18 and D18s: CCTV video inspection of pipeline defects

5. Pipeline periscope D16S: quickly  view the internal defects of the pipeline

Headquartered in Shanghai, Daoyunai has a number of independent intellectual property rights and also has a manufacturing base and R&D and testing center in Suqian City, Jiangsu Province, covering an area of more than 35000 square meters, which fully implements the international quality management system.
