Cured-In-Place-Pipe UV Cured CIPP Services DN1200 Sewers Renewal Construction

Raw material for sewers renewal construction by the trenchless technology

Notes on construction:

In some pipelines, there will be accumulated water that cannot be treated cleanly.

The material head must be padded higher to ensure that there is no water in the prepreg layer and the inner membrane layer at the opening of the material head. The water inflow material in the prepreg layer will turn white and will not solidify, and the water inflow in the inner membrane will greatly increase the solidification.

It will not solidify when the time is serious. The waterproof performance of Daoyu energy-saving technology material is excellent, and there will be no water in other places except at the openings at both ends.

In addition, according to different pipe diameters, the size of the binding head is also different. If conditions permit, the binding head below DN600 can be installed on the ground.

For those below DN600, which are basically larger than the manhole diameter, tie heads at both ends shall be installed at the pipe bottom.

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.
