As a leading manufacturer with over a decade of experience, Qingdao Yongke Machinery Co., Ltd. is proud to introduce our Precision-Engineered UV Cured CIPP Liner. Engineered for the complex challenges of modern pipeline networks, this solution represents a significant advancement in trenchless rehabilitation technology. Operating from our expansive 10,000-30,000 square meter facility, we combine rigorous manufacturing processes, certified under ISO9001, ISO14000, and OHSAS18001, with deep industry knowledge to deliver a product that restores structural integrity with minimal disruption. Our UV Cured CIPP Liner is designed specifically for intricate pipeline systems, offering a reliable, efficient, and structurally sound method for municipalities and industrial clients worldwide to address aging infrastructure.
Core Product Advantages & Technical Specifications:
This liner transforms pipeline restoration by utilizing advanced ultraviolet light curing technology. Unlike traditional steam-cured methods, UV curing offers superior control, consistency, and energy efficiency. The process involves inserting a flexible, resin-impregnated tube into the host pipe, which is then inflated and cured into a hard, jointless "pipe-within-a-pipe" using high-intensity UV lamps.
- Superior Structural Performance: The UV curing process allows for precise control over the polymer's cross-linking, resulting in a liner with enhanced mechanical properties, including high flexural strength and excellent chemical resistance.
- Adaptability to Complex Networks: Perfect for rehabilitating pipelines with bends, diameter changes, and difficult access points. The flexibility of the uncured liner allows it to navigate these complexities before being set into a rigid, seamless new pipe.
- Rapid, Energy-Efficient Installation: UV curing is significantly faster than thermal methods for many applications, reducing project timelines. It also consumes less energy, lowering operational costs and environmental impact.
- Minimal Site Disruption: As a trenchless technology, it eliminates the need for extensive excavation, preserving landscapes, reducing traffic delays, and lowering restoration costs.
- Long-Term Corrosion Resistance: The cured liner acts as a barrier, protecting the host pipe from corrosive elements in wastewater and industrial effluents, thereby extending the asset's lifespan.
Key Technical Parameters:
The following table outlines typical specifications. All parameters can be customized based on project requirements.
| Parameter | Specification Range / Detail |
| Host Pipe Diameter Range | 100 mm to 1200 mm (customizable beyond) |
| Standard Liner Thickness | 3 mm to 12 mm (project-specific) |
| Curing Mechanism | Ultraviolet (UV) Light |
| Primary Material Composition | Fiberglass or Polyester Felt + UV-Curable Resin |
| Typical Curing Speed | Varies with diameter, thickness, and lamp power |
| Chemical Resistance | High resistance to acids, alkalis, and hydrocarbons |
| Application Temperature Range | Suitable for most municipal and industrial conditions |
Benefits for Your Project:
- Cost-Effective Solution: Reduces total project cost by minimizing excavation, traffic management, and post-installation restoration expenses.
- Enhanced Flow Capacity: The smooth interior surface of the cured liner often improves hydraulic flow compared to the original corroded pipe.
- Non-Disruptive: Ideal for use under roads, buildings, and environmentally sensitive areas where open-cut methods are impractical or prohibited.
- Durability & Longevity: Designed to meet or exceed the design life of a new pipe, providing a permanent rehabilitation solution.

Frequently Asked Questions (FAQ)
-
Q: How does UV curing compare to traditional steam curing for CIPP?
A: UV curing provides more precise control over the hardening process, leading to more consistent material properties. It is often faster, uses less energy, and can be better suited for certain resin systems, resulting in a liner with excellent mechanical strength and chemical resistance. -
Q: Can this liner be used for pipes with multiple bends?
A: Yes, one of its primary advantages is handling complex geometries. The flexible, uncured liner can be inverted or pulled through pipes with bends and laterals before it is cured into a rigid shape. -
Q: What is the typical service life of a UV-cured CIPP liner?
A: When installed correctly, a UV-cured CIPP liner is designed as a permanent rehabilitation, often with a service life exceeding 50 years, depending on the specific environmental and operational conditions. -
Q: Is the installation process disruptive to daily operations?
A: Minimally. The trenchless nature of the technology means most work occurs at access points (manholes). Traffic and business disruptions are significantly reduced compared to open-cut excavation. -
Q: What pipe materials can be rehabilitated using this method?
A: It is effective for a wide range of host pipes including vitrified clay, concrete, cast iron, ductile iron, PVC, and some types of steel, provided the pipe is structurally sound enough to act as a mold. -
Q: How do you determine the required liner thickness for a project?
A: Thickness is engineered based on the host pipe's condition, diameter, depth, soil loading, and required long-term performance. Our technical team can assist with these calculations based on your project data. -
Q: Are there any limitations on the diameter or length of pipe that can be rehabilitated?
A: While standard projects cover diameters from 100mm to 1200mm, both larger and smaller diameters can be accommodated. Lengths are typically limited by the distance between access points and the capabilities of the installation equipment. -
Q: What certifications does your manufacturing process hold?
A: Our production is managed under integrated management systems certified to ISO9001 (Quality), ISO14000 (Environment), and OHSAS18001 (Occupational Health & Safety), ensuring a controlled and reliable manufacturing environment.
