Underground UV Cured CIPP Equipment Cured Lining Fiberglass Saturated Resin Installation

Fiberglass saturated resin installation for underground pipelines by no excavation

UV CIPP trenchless construction for sewer repair

At the same time as pulling the liner, the operator at the bottom of the inspection well shall be in place to assist the hose at all times to ensure that it is always at the bottom of the pipe without touching the top of the pipe.

If the material diameter is greater than or equal to DN600, it is recommended to apply grease or detergent water at the bottom of the material or above the bottom film to reduce friction.

At the same time, pay attention to the flatness of the material at all times to ensure that it is not knotted or bent. Otherwise, once the material enters the pipeline, it will be difficult to fully expand in case of winding, resulting in waste and economic losses.

At the end of the manhole section, the person responsible for dragging the bottom film and hose should use a hoist, which requires 3-5 tons.

Always pay attention to the safety of operators at the bottom of the manhole.

For the pipes below DN600, the lamp chain shall be used for curing, and the installation of the stainless steel tie at one end and the assembly of the lamp chain shall be completed on the ground.

For pipelines above DN600, the lamp holder shall be used for curing. If the manhole or wellhead is too small, the installation of stainless steel binding head and the assembly of the lamp holder shall be completed inside the pipeline.

When the hose is still 5 meters long, stop dragging and start to install stainless steel ties.

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.
