UV lining materials for trenchless curing sewers in the municipal department

Classification:

The second type is divided into local repair and overall repair according to the repair length.

Local repair refers to the repair of short-distance pipes, generally with a longitudinal length of less than 500mm.

Overall repair is to repair one pipe section at a time, that is, the pipeline from one inspection well to another inspection well. Sometimes it can even cross multiple inspection wells continuously. The length of one-time repair varies from 20 meters to 50 meters to 100 meters, or even 300 meters.

The overall repair can be divided into semi-structural repair and full structural repair, which are calculated and determined based on the comprehensive consideration of the original pipeline damage status: long-term modulus, long-term bending strength, Poisson's ratio, groundwater load, water buoyancy coefficient, soil load, soil density, and other factors.

The trenchless repair technology of the CIPP UV curing pipeline belongs to integral and full structural repair, which is suitable for both rescue projects and preventive urban operation and maintenance. It is widely used all over the world because of its wide application range, fast construction speed, and excellent repair results.

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.
