UV curing repair of pipelines

CIPP ultraviolet curing repair method for in-situ integral lining of pipelines,Pipeline non excavation UV curing repair, CIPP. UV pipeline UV curing repair technology provided, municipal pipeline non excavation repair, using CIPP UV curing lining repair. The non excavation repair technology for pipelines applies UV curing repair, and Jiangsu Nanpai Municipal Pipeline Non excavation Repair Engineering Co., Ltd. applies UV curing repair technology and CIPP-UV lined UV curing resin repair method.

Jiangsu Nanpai Municipal Government has mastered new ultraviolet light repair methods, CIPP flipping in-situ curing method, point local resin curing method and other repair technologies, which can quickly solve problems such as pipeline deformation, rupture, disconnection, collapse, tree roots, etc. Pipeline light curing in-situ CIPP lining repair, pipeline non excavation repair - pipeline ultraviolet light curing - spiral winding repair - CIPP in-situ curing - pipeline cleaning CCTV robot detection Due to some narrow streets in the old city area and shallow foundations of residential houses along the streets, sewage pipes cannot be installed on sidewalks. Since last year, the urban water project has been implemented to further improve the water quality of urban areas from "good water" to "clean water" and "beautiful water". As of now, the sewage pipe network construction and repair projects included in this year's practical projects have exceeded the annual targets.

Introduction to the construction of UV-CIPP pipeline UV curing repair in Nanpai City, Jiangsu Province,CIPP-UV ultraviolet curing repair method for in-situ lining of pipelines without excavationUV-CIPP pipeline UV curing repair technology is one of the in-situ curing methods for non excavation repair. The industry standard "Technical Regulations for Non excavation Repair and Renewal Engineering of Urban Drainage Pipelines" (CJJ/T210-2014) issued by the Ministry of Housing and Urban Rural Development defines in-situ curing method as the repair method of using flipping or pulling to place the impregnated resin lining pipe into the original pipeline, and curing it to form the pipeline lining.

UV light curing technology is an in-situ curing method in which glass fibers are woven into flexible tubes and impregnated with resin, and then pulled into the original pipeline for inflation and expansion, tightly adhering to the original pipeline. Under the action of ultraviolet light, the resin is cured to form an inner lining tube with a certain strength. Due 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:

adoptPipeline non excavation CIPP-UV in-situ lining methodUV light curing has a particularly fast repair speed, usually taking 3-4 hours to complete all the work. Compared to the 12-30 hours of cipp flipping, it greatly saves construction time and has a huge advantage for crowded areas such as commercial districts and city centers.
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 batches of resin production each time result in significant differences in product quality. This is why the quality of cipp flipping engineering is unstable. 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 conveying capacity of cipp flipping materials and increases costs.
The main business of Jiangsu Nanpai Municipal Government includes non excavation ultraviolet curing repair (UV cipp), local resin curing, stainless steel double expansion ring, pipeline inspection well spraying method, UV cipp pipeline UV curing repair. To meet the needs of different customers for non excavation pipeline repair, Jiangsu Nanpai Municipal Government has introduced two sets of German UV cipp repair equipment, three sets of hot steam curing repair equipment, several sets of HDPE lining equipment, as well as related technologies and equipment such as local cipp method, stainless steel double expansion ring method, spraying method, stainless steel lining method, fractured pipe method, spiral winding method, etc. It is committed to building a diversified and comprehensive pipeline non excavation repair technology service. Various non excavation repair techniques such as polyurethane spraying, HDPE short pipe lining method, pipe crushing method, cipp flipping method, cipp thermosetting method, spiral winding method, etc.
