Pipe CCTV Inspection

Step 1: Plug-release the crew and gas pipelines, water blocked tube after pumping out the water.
Step 2: Using high-pressure water jetting machine inside the tubes Choi, washing their basic hardware is not covered by the sludge.
Step 3: will be on display at the camera inside the tubes of CCTV cameras were installed in the sewer Tractor progress, the use of thrust or power in the pipeline to detect movement in the pipeline.
Step 4:: operator observation & Records entered the pipeline when the cameras after images were transmitted to the ground clearly on the screen and then, operators will be recorded pipeline E internal structural deficiencies, and the camera recorded the pipeline path and see pipeline situation.

With the development of economy and urbanization, many old underground pipelines have been broken due to the activity from the surface for a long period of time. So these pipes need to be repaired or be totally replaced. Usually it is quite impossible for maintenance workers to dig a large hole and replace the old pipe with a new one in the downtown area. And if we do so, it may take up too much space, time, destroy green field, cause the traffic jam and may affect the other underground facilities. We can use Trenchless Rehabilitation Method to solve this problem. These technology are imported from overseas, we also have various options for customers such as Spiral Wound Lining, Spot Rehabilitation, CIPP (Cured In Place Pipe), Pipe Bursting methods and so on.

Spot Rehabilitation

Guided by the CCTV camera system vehicle, we use the self-invented rehabilitation device to repair the partial defection to restore the lining. It is suitable for pipe with diameter of 800mm and below which is impossible for man to go down.

CIPP (Cured In Place Pipe) rehabilitation technique consisting of the insertion of a flexible tube of fibrous matrix, which is filled by an thermosetting resin, into a water main, which produces a structural pipe when cured.

Pipe Bursting

Pipe bursting is a technique for replacing pipes by breaking them open from within, at the same time a new pipe is pulled in behind the bursting tool. This can be applied to replace the old ceramic, concrete, eternit, plastic or cast iron pipelines. We can replace the existing old pipe to the same diameter or 150% larger.
