The in-situ repair of non excavated pipelines (CIPP) ultraviolet light curing technology refers to the use of UV-CIPP lined hoses pulled into the pipeline to be repaired from the wellhead, tied at both ends of the hose, and then compressed air is injected to support the hose and make it tightly adhere to the inner wall of the pipeline. Through ultraviolet irradiation, the inner lining of the pipeline is rapidly cured and shaped, forming a non excavation pipeline repair technology called "pipe in pipe". Partial repair is possible, and non excavation saves labor costs, time costs, and longer pipeline service life. After pipeline repair, there is no need for manual cleaning and normal drainage can be achieved.

Ergou Optoelectronics UV Curing UV-CIPP Repair Technology is suitable for pipes with a diameter of 150-1600mm. After connecting the inner lining to the pipeline, air is filled to support it and stick it tightly to the inner wall of the pipeline. Then, a UV fixing lamp is placed, and the lamp chain can irradiate the pipe wall 360 degrees when moving inside the pipe, quickly curing and shaping it. The molded lining can be used normally without manual cleaning. The repaired pipeline has a long service life and is highly efficient and cost-effective compared to traditional excavation techniques.

The UV curing machine is fully equipped and has a wide range of applications: the wire speed is 0.05-4m/min, suitable for pipe diameters of DN150-1600, with a built-in 160m high-temperature resistant light curing cable, which can withstand high temperatures of 150 ℃ and work continuously for a long time, and has strong environmental adaptability. The construction site does not require a water source, the equipment operation is simple, and the construction efficiency is extremely high. The head of the light chain is equipped with a camera, which can transmit images to the monitor in real time, and the operator can control the solidification situation inside the tube in real time.
