UV curing repair process for UV CIPP lining in pipelines

Pipeline UV curing repair CIPP-UV lining processCIPP non excavation pipeline UV curing repair pipeline UV curing repair: UV-CIPP lining method is suitable for underground rainwater, sewage pipelines or ditches. A reliable drainage pipeline repair plan. Currently in Germany, CIPP pipeline UV curing repair can produce hoses up to 500M in length in one go. Even if there are changes in the size of a section of the pipeline or if the pipeline has a curvature of less than 30 °, wrinkle free repair can be performed. Flexible hoses are suitable for various types of pipelines, including circular, elliptical, egg shaped, square, and other special shapes. The range of inner lining repair is from DN150 to DN1200, and the inner lining wall thickness ranges from 3mm to 12mm. With flexible, diverse, fast, and highly innovative capabilities, as well as short response times and effective problem-solving methods, the UV curing CIPP inner lining repair process and device save a lot of resources in the planning and construction stages of urban pipe network repair.

Pipeline UV curing repair CIPP-UV lining processDue to the fact that pipeline UV curing repair is completed by ester injection in the factory, it can be stored at a temperature of 5-30 degrees for 6 months or more. If the storage conditions are appropriate, the following characteristics of pipeline UV curing repair materials are:

Due to the completion of ester injection in the factory, construction can be carried out directly on the construction site, greatly reducing the construction time

2. Due to the use of ultraviolet light for curing, the repair speed is particularly fast, usually taking 3-4 hours to complete all the work. Compared to the 12-30 hour flipping time of CIPP, it greatly saves construction time and has a huge advantage for crowded areas such as commercial districts and city centers.

3. The quality of pipeline repair is stable. Due to the use of automated methods in the factory, UV curing repair of pipelines involves immersing resin into fiberglass fibers and then winding them together to form pipes, without the need for on-site manual injection of resin, resulting in relatively stable quality. For CIPP flipping, it is necessary to manually inject resin each time, and the different resin production batches result in significant differences in product quality. This is why the quality of CIPP flipping engineering is unstable.

4. UV cured repair materials for pipelines can be transported remotely, while CIPP flipping materials need to be transported to the construction site by refrigerated trucks after resin injection, which greatly limits the transportation capacity of CIPP flipping materials and also greatly increases costs.
