Construction material used for international city pipes repair w/o digging

The UV curing overall repair lining material is made of unsaturated polyester resin, which has the characteristics of convenient curing, strong adhesion, and low shrinkage. The lining material is made of high-strength glass fiber, which can significantly reduce the wall thickness, greatly reduce the weight of the overall lining material, save the installation cost, and provide a stronger ring direction tensile performance for resistance to pressure.

Scope of application:

1. it can match various pipe geometric sections, including round, square, horseshoe, etc.

2. Is suitable for rain and sewage drainage pipes made of reinforced concrete, cement, metal, and various plastic materials It can repair the structural defects of the pipeline: fracture, deformation, dislocation, disconnection, leakage, corrosion, etc.

• it is applicable to repair local sand holes, exposed stones, spalling and other diseases on the inner wall of the pipeline
• It is applicable to the preventive repair when the pipeline-interface is in the leakage omen period or critical state.
• Applicable pipe diameter range: DN200-DN1600.

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.
