As a leading manufacturer with over a decade of experience, Qingdao Yongke Machinery Co., Ltd. specializes in providing advanced trenchless pipeline rehabilitation solutions. Our Industrial UV Cured CIPP Liner System represents a significant leap forward in high-pressure pipe repair technology. Engineered for durability and efficiency, this system offers a robust, cost-effective alternative to traditional excavation methods, minimizing disruption and maximizing pipeline lifespan. We combine our extensive manufacturing capabilities from our 10,000-30,000 square meter facility with stringent quality controls to deliver a product trusted by clients across North America, South America, Europe, Asia, and beyond.
Core Technology & Process: Our system utilizes the proven Cured-in-Place Pipe (CIPP) method, enhanced with state-of-the-art Ultraviolet (UV) light curing. A flexible, resin-impregnated liner is inverted or pulled into the damaged host pipe. Subsequently, UV light trains are deployed to cure the liner rapidly, forming a jointless, structural "pipe-within-a-pipe." This UV curing process offers precise control, resulting in a liner with consistent mechanical properties and superior bond strength.
Key Product Features & Advantages:
Trenchless & Non-Disruptive: Eliminates the need for extensive digging, preserving landscapes, roadways, and infrastructure. This drastically reduces restoration costs and project timelines.
Superior Structural Integrity: The UV-cured liner forms a rigid, continuous new pipe with high flexural and tensile strength, capable of withstanding significant internal and external pressures.
Corrosion & Chemical Resistance: The inert polymer composition provides excellent resistance to a wide range of corrosive chemicals, acids, and abrasives, extending service life in aggressive industrial environments.
Hydraulic Efficiency: The smooth interior surface of the cured liner reduces friction loss (Hazen-Williams C-factor >150), often improving flow capacity compared to the original pipe.
Rapid Installation & Curing: UV curing is significantly faster than traditional thermal or steam curing methods, allowing for quicker return-to-service, sometimes within hours.
Long-Term Seal: Effectively seals cracks, joints, and leaks, preventing groundwater infiltration and exfiltration, which protects soil and groundwater quality.
Design Flexibility: Systems can be engineered for various pressures, diameters, and service conditions, including potable water, industrial effluent, and pressure pipelines.

Frequently Asked Questions (FAQ)
Q: What types of pipes can this UV Cured CIPP system repair?
A: It is suitable for rehabilitating a wide range of pressurized pipelines, including those made of concrete, clay, cast iron, ductile iron, and steel, commonly used for potable water, industrial process lines, and force mains.Q: How does UV curing compare to traditional steam curing for CIPP?
A: UV curing is typically faster, more energy-efficient, and offers superior control over the curing process, leading to more consistent mechanical properties and reduced risk of incomplete curing in longer runs.Q: Can the system handle bends or changes in pipe diameter?
A: Yes, the flexible liner can navigate standard bends (typically up to 90 degrees with proper radius) and can be designed to accommodate diameter changes, though specific engineering assessment is required.Q: What is the maximum pressure this rehabilitated pipe can withstand?
A: The final pressure rating depends on the original host pipe condition, liner thickness, and design. Our engineers perform detailed calculations based on ASTM standards to ensure the rehabilitated line meets or exceeds the required operating pressure.Q: Is the cured liner safe for potable water applications?
A: Yes, we can supply liners and resins that are certified to relevant international standards for potable water contact (e.g., NSF/ANSI 61). Certification documentation is available upon request.Q: What is the typical installation timeline for a project?
A: While it varies with length and diameter, a typical installation—including cleaning, liner insertion, UV curing, and reinstatement of service connections—can often be completed within 1-2 days for several hundred meters.Q: Do you provide training or technical support for the installation?
A: We offer comprehensive technical documentation, installation guidelines, and can arrange on-site or remote technical support to ensure proper installation by qualified contractors.Q: How do I determine the right liner thickness for my project?
A> We provide a project assessment questionnaire. By providing details like pipe diameter, depth, soil conditions, and operating pressure, our engineering team will recommend the optimal design.
