As a leading manufacturer in trenchless technology since 2010, Qingdao Yongke Machinery is proud to introduce our advanced No-Dig Pipe Repair System with Fast UV Curing for precise spot rehabilitation. Engineered in our 10,000-30,000 sqm facility, this system represents a significant leap in efficient pipeline maintenance, designed to address localized defects without the need for extensive excavation. It delivers a fast, reliable, and structurally sound repair, minimizing downtime and community disruption for municipalities and utility contractors worldwide.
This innovative system is specifically engineered for the targeted rehabilitation of isolated pipeline defects such as cracks, joint failures, or localized corrosion. By combining a robust, resin-impregnated liner with a high-intensity UV light curing train, we offer a solution that sets quickly to form a durable, jointless "pipe-within-a-pipe." This method is not only cost-effective compared to full-length pipe replacement but also dramatically reduces environmental impact and restores service in a fraction of the time.
Core Product Features & Technical Advantages:
High-Speed UV Curing: Our system utilizes a specialized UV light train that triggers a rapid photochemical reaction in the liner's resin. This process cures the material in a matter of minutes, not hours, allowing for quick return-to-service and high daily productivity on repair projects.
Precision Spot Repair: The system is optimized for pinpoint accuracy, enabling contractors to rehabilitate only the damaged section of pipe. This targeted approach conserves materials and reduces overall project costs while effectively restoring structural integrity.
Robust Structural Liner: The felt liner is impregnated with a high-grade, UV-curable resin. Once cured, it forms a rigid, corrosion-resistant composite that is independent of the host pipe, capable of withstanding internal pressures and external loads.
Minimal Operational Footprint: As a true no-dig solution, it requires only small access pits at manholes. This eliminates the need for open trenches, preserving landscapes, roadways, and reducing traffic congestion and safety hazards.
Versatile Application Range: The system can be configured to repair pipes from 100mm (4 inches) to 1200mm (48 inches) in diameter, covering a wide range of municipal sewer, stormwater, and some industrial pressure piping applications.
Integrated Control System: A centralized control unit allows for precise monitoring and management of the UV curing process, including light intensity, exposure time, and train movement, ensuring consistent, high-quality results every time.

| Power Requirement | 380V/50Hz or 440V/60Hz (Configurable) |
| Control System | PLC-based with Touchscreen HMI for process control |
| Air Supply Requirement | Integrated or external air compressor (7-10 bar) |
Benefits for Your Operations:
Reduced Project Timelines: Fast curing translates directly into more repairs completed per day, optimizing crew efficiency and meeting tight municipal schedules.
Lower Total Cost: Eliminates expensive excavation, backfill, and surface restoration costs. The precision of spot repair also minimizes material usage.
Enhanced Safety: Significantly reduces risks associated with deep trenching, such as collapses, utility strikes, and worker injuries.
Long-Term Performance: The cured liner is highly resistant to chemical attack from sewer gases and wastewater, providing a durable, long-lasting repair that can extend pipe life by decades.
Environmental Stewardship: Drastically reduces carbon footprint by avoiding heavy machinery use for excavation and minimizing waste material sent to landfills.
Backed by over a decade of manufacturing expertise and a commitment to international quality standards, Qingdao Yongke Machinery delivers reliable trenchless solutions. Our systems, developed by a team of 51-100 skilled professionals, are trusted across global markets from North America and Europe to Southeast Asia and Oceania, with an annual export value reflecting consistent customer confidence.

Frequently Asked Questions (FAQ)
Q: What types of pipe defects is this spot repair system best suited for?
A: This system is ideal for localized issues such as circumferential cracks, leaking joints, localized corrosion, or minor root intrusions. It is designed for structurally sound pipes that have isolated defects, not for pipes that have completely collapsed or have widespread degradation.Q: How does the UV curing time compare to traditional steam or hot water curing for CIPP?
A: UV curing is significantly faster. While traditional methods can take several hours, our UV system typically cures the liner in minutes per meter. This rapid process allows for multiple spot repairs in a single work shift.Q: Is the cured liner resistant to chemicals commonly found in sewers?
A: Yes. The UV-cured resin matrix forms a highly cross-linked polymer that provides excellent resistance to sulfuric acid (from H2S gas), hydrocarbons, and other aggressive substances typically found in sewer environments.Q: Can the system navigate bends or repair defects near junctions?
A: The flexibility of the uninflated liner and the design of the UV train allow it to pass through gradual bends. For repairs very close to junctions or sharp bends, a site assessment is recommended to determine the optimal installation approach.Q: What is the typical service life of a UV-cured spot repair?
A: When installed correctly, a UV-cured spot rehabilitation can restore the structural integrity of the pipe section for 50 years or more, effectively creating a new pipe within the old one at the defect location.Q: What training and support do you provide with the system?
A: We provide comprehensive operational training, either at our facility in Qingdao or on-site at your location. This includes hands-on instruction for your crew, along with detailed technical manuals and ongoing remote support.Q: Are custom liner diameters and lengths available?
A: Absolutely. As a manufacturer, we specialize in customizing the liner dimensions (diameter and length) to match your specific project requirements, ensuring a precise fit for any spot repair need.Q: What are the main power and utility requirements on-site?
A: The system typically requires a standard three-phase power connection (configurable to local standards) and a source of compressed air. All requirements will be detailed in the technical datasheet provided with your equipment.
