How to efficiently and environmentally repair aging pipelines in modern infrastructure maintenance? UV-CIPP, as the core material of non excavation repair technology, is becoming a "repair tool" in municipal, industrial and other fields due to its fast curing, high strength and environmental advantages. This article will provide you with a comprehensive understanding of the structure, performance, and application scenarios of this innovative product.
Product Introduction
UV cured hose is a composite polymer material hose reinforced with glass fiber or polyester fiber, which undergoes resin curing reaction through UV irradiation to form a high-strength inner lining pipeline. Its core advantages include:
Quick construction: curing can be completed in 2-4 hours, greatly reducing the construction period;
Zero excavation repair: No need to damage the road surface, reducing social costs;
Ultra long service life: corrosion resistance, anti-aging, service life of more than 50 years;
Green and environmentally friendly: No wastewater or exhaust emissions, with a styrene residue rate of less than 2%.
Product Structure and Raw Material Function
As a "black technology" for modern non excavation pipeline repair, the performance of UV cured hoses directly determines the service life and safety of the repaired pipeline. In technical parameters, short-term bending strength, short-term bending modulus of elasticity, and tensile strength are the three core indicators. Short term bending strength: reflects the ability of the hose to resist external bending deformation after solidification. The higher the value, the more it can prevent the pipeline from bending and breaking in complex geological environments; Short term bending modulus of elasticity: represents the rigidity of the material. The larger the modulus, the less likely the hose is to deform due to soil pressure or external compression after solidification; Tensile strength: measures the ultimate bearing capacity of a material under tension, ensuring that the repaired pipeline can withstand long-term tensile forces such as groundwater seepage and vehicle loads. These three indicators together form the "strength triangle" of pipeline repair, providing scientific guarantees for the safe operation of underground pipelines. The long-term bending modulus of elasticity is a core parameter for measuring the ability of UV cured liner to resist bending deformation under continuous stress. Simply put, the long-term bending modulus of elasticity is like the "bending resistance value" of a hose, which reflects whether the lining can maintain its "flexibility and controllable deformation" characteristics when subjected to repeated bending or pressure for a long time. If the long-term bending elastic modulus is too low, the material is prone to fatigue relaxation and even permanent bending deformation due to repeated stress. The bending modulus of elasticity of the lining tube extrapolated to 50 years later still far exceeds the national standard acceptance requirements, ensuring its long-term service life.

Why choose UV cured hoses? ·Efficient and environmentally friendly, convenient construction Traditional excavation and repair methods have long construction periods and high costs, while UV curing technology uses non excavation methods to insert resin impregnated hoses into old pipelines, which can be quickly cured by UV irradiation (usually completed in 1-4 hours), greatly reducing the construction period and eliminating harmful gas emissions, in line with the concept of green construction. ·Excellent mechanical performance The cured hose has excellent short-term bending strength and tensile strength, and can resist underground soil pressure, vehicle loads, and water flow impact; Short term bending elastic modulus is high, ensuring that the pipeline maintains a stable shape in the long term, avoiding collapse and deformation, especially suitable for complex geological or heavily trafficked areas. ·Long lifespan, once and for all The material has strong corrosion resistance and can resist chemical media such as sewage, acid and alkali erosion. Its service life is over 50 years, avoiding the trouble of repeated maintenance. Meanwhile, a smooth inner wall can improve water delivery efficiency and reduce energy loss. ·Strong adaptability and wide application Whether it is municipal drainage pipes, industrial pipelines, or narrow and curved branch pipes, UV cured hoses can be customized to match different pipe diameters and working conditions, providing reliable guarantees for the "longevity and rejuvenation" of urban underground pipelines. As the "invisible guardian" in the field of non excavation restoration, UV cured hoses reshape urban underground lifelines with the power of technology.
