Lining material for pipe renewal and renovation via CIPP trenchless technology

UV lining material characteristics

1. After repair, there is no joint in the pipe, the overall thickness is uniform, the surface is free of damage, large-area folds, and bubbles, and the inner wall surface is smooth, effectively improving the water passing capacity of the pipe.

2. the whole pipe has no interface and can adapt to non-circular sections and curved pipes.

3. Various pipe materials have strict requirements for pipeline repair pretreatment. No sundries and ponding are allowed in the pipeline to be repaired.

4. the construction period is short, and the fastest curing speed can reach 2m/ min.

5. The construction is convenient, and the material can react after being irradiated by light without preheating; The service life shall not be less than 30 years according to the design requirements, and the longest service life can be up to 50 years.

6. The materials are pulled into the pipeline in advance, and the construction steps are simplified. 7. the construction is safe. The whole reaction process of materials is carried out in the pipeline without personnel going down the well. The whole construction process is not limited by seasonal areas.

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.
