Application of UV curing technology in underground pipeline repair——Beijing Pro-line Pipeline Technology Co., Ltd. will hold Beijing International Underground Pipeline Exhibition in September

Established in January 2015, Beijing Pro-line Pipeline Technology Co., Ltd. is a high-tech enterprise specializing in the R & D, production and sales of uv-cipp lined hose and UV curing equipment. It is also the first enterprise in China to industrialize the production of uv-cipp lined hose.

As a kind of CIPP trenchless repair, UV curing pipeline in-situ repair technology uses pull in method to pull rolled glass fiber hose into the old pipeline to be repaired, and solidifies by UV light, eliminating the links of erection, turnover and water consumption, realizing the advantages of environmental protection, saving, low cost and 100% trenchless repair, Has been recognized and used by our customers.

Technological advantages

(1) It has little influence on traffic. True 100% trenchless lining repair, no excavation work pit.

(2) Good controllability and short construction period. Pull in positioning is adopted, without overturning, and CCTV monitoring is solidified in the whole process; The construction of each section does not consider the cleaning of the pipe wall, and the pulling in and curing can be completed in only 3 to 4 hours.

(3) Energy saving and high security. UV curing has low energy demand, no water or steam curing at the construction site, and no toxic gas or other harmful substances are produced. It is very beneficial to ensure the safety of construction personnel and nearby personnel and protect the environment.

(4) The lined hose has good sealing effect, strong corrosion resistance and service life of 50 years.

(5) The loss of current carrying capacity is low. Compared with felt and other lining materials, pro liner hose can achieve the same strength as polyester felt lining with thinner wall thickness (3 to 15mm), thus reducing the inner diameter of the pipe.

(6) Has higher elastic modulus, bending strength and tensile strength. Compared with the traditional lined hose made of synthetic fiber such as polyester felt, the pro liner hose is made of reinforced glass fiber composite material, which can bear much higher load than the traditional lined hose made of synthetic fiber.

Based on the introduction of German advanced uv-cipp hose production patent technology and the integration of foreign senior hose production line design force, Pro-line has built a hose production rubber mill and supporting facilities on the basis of the existing German production line, making Pro-line hose production line reach the world-class process level. The shape, diameter and wall thickness range of the hose have reached the world leading level. In terms of curing equipment, combined with the unique construction environment of domestic underground pipelines, Pro-line has developed ultraviolet hose curing equipment with independent intellectual property rights, which can meet the curing construction requirements of different pipe diameters. At the same time, Pro-line has German uv-cipp hose and UV curing machine technical expert team, local R & D team and professional after-sales service team to provide customers with timely and comprehensive technical support and other professional services.
