As a leading manufacturer established in 2010, Qingdao Yongke Machinery Co., Ltd specializes in providing robust and efficient solutions for modern infrastructure renewal. Our UV CIPP Liner Production Equipment is engineered specifically for the demanding requirements of large-diameter pipeline rehabilitation projects. With over a decade of experience and a sprawling factory spanning 10,000-30,000 square meters, we understand the critical need for reliable, high-throughput machinery that ensures project timelines are met without compromising on the quality of the rehabilitated pipeline. This equipment represents our commitment to advancing trenchless technology, offering municipal authorities and contracting companies a powerful tool to extend asset life, reduce environmental disruption, and achieve significant cost savings compared to traditional dig-and-replace methods.
Our equipment is designed to transform resin-impregnated felt or fiberglass liners into structurally sound, corrosion-resistant new pipe walls inside existing host pipes. The core of this process is precise UV light curing, which offers distinct advantages over traditional thermal or steam curing methods.
- Superior Curing Control: The system utilizes high-intensity UV lamps arranged in a configurable array to ensure uniform light exposure across the entire circumference and length of the large-diameter liner. This controlled curing prevents under-cured or over-cured sections, resulting in a consistent mechanical performance.
- Enhanced Material Properties: UV curing initiates a rapid photopolymerization reaction in the resin. This process typically yields a finished liner with excellent chemical resistance, high structural strength (often exceeding the host pipe), and a smooth interior surface that improves hydraulic flow.
- Operational Efficiency: Curing cycles with UV technology are significantly faster than thermal methods. This drastically reduces the on-site project time for each pipeline segment, allowing contractors to rehabilitate more linear feet per day and complete projects ahead of schedule.
- Energy and Environmental Benefits: The system consumes less energy than large steam boilers or heaters. It also produces minimal volatile organic compound (VOC) emissions during the curing process, making it a more environmentally friendly choice, especially important for projects in sensitive areas.
The equipment is built with a modular and scalable architecture to handle the large scales involved. Key technical specifications and configurations are outlined below:
| Component/Parameter | Description & Features |
|---|---|
| UV Curing Chamber | Engineered for large diameters; features reflective interior for optimal light distribution; access doors for maintenance; insulated for operator safety. |
| UV Lamp Array | Custom-configurable array of medium-pressure mercury vapor UV lamps; individual lamp monitoring; adjustable intensity settings for different resin chemistries. |
| Tensioning & Inversion System | Integrated or compatible system for precise liner positioning and inversion into the host pipe, ensuring wrinkle-free installation before curing. |
| Control Panel | Centralized PLC-based control with a user-friendly HMI (Human-Machine Interface); programmable curing profiles; real-time monitoring of UV intensity, temperature, and curing time. |
| Cooling & Ventilation | Active cooling system to manage heat from UV lamps; integrated ventilation to maintain a safe working environment. |
| Power Requirements | Designed to be customizable based on regional electrical standards (e.g., 380V/50Hz or 480V/60Hz); available upon request. |

Frequently Asked Questions (FAQ)
-
Q: What is the typical diameter range this equipment can handle?
A: Our equipment is designed for large-diameter applications. The specific range is customizable based on your project focus. We engineer the curing chamber and UV array to suit diameters commonly encountered in municipal and industrial mainline rehabilitation. Please contact us with your target diameter for a detailed proposal. -
Q: How does UV curing compare to steam curing in terms of final liner strength?
A: UV-cured liners generally achieve excellent mechanical properties, often matching or exceeding those from steam curing. The rapid, controlled reaction can lead to a more uniform polymer structure. The specific strength depends on the resin and felt used, but UV curing is a proven method for creating structurally independent, high-strength pipe liners. -
Q: Is the equipment mobile or trailer-mounted for easy transport between job sites?
A: The system can be configured based on your operational needs. We offer skid-mounted modules that can be easily transported on flatbed trucks and positioned at the job site, as well as more permanent containerized or trailer-mounted solutions for maximum mobility. -
Q: What kind of training and technical support do you provide?
A: We provide comprehensive on-site commissioning and operator training with the purchase of the equipment. Our technical support team is also available remotely for troubleshooting. Detailed operation and maintenance manuals are supplied in English. -
Q: Can the system be adapted for different UV-curable resins from various suppliers?
A: Yes. The PLC control system allows for creating and storing multiple custom curing profiles. Parameters like UV intensity, exposure time, and rotation speed can be adjusted to optimize the cure for different resin types and thicknesses recommended by liner manufacturers. -
Q: What are the main safety features incorporated into the design?
A: Safety is paramount. Features include interlocked access doors that shut off UV power when opened, UV-blocking viewing windows, emergency stop buttons, ground fault protection, and continuous monitoring systems for temperature and electrical parameters. -
Q: What is the typical lead time for manufacturing and delivery?
A: Lead time varies based on the project's complexity and customization level. For a standard large-diameter configuration, typical production time is in the range of 90-120 days after order confirmation, excluding shipping time from Qingdao port. -
Q: Do you offer spare parts and long-term maintenance support?
A: Absolutely. As the manufacturer, we maintain an inventory of critical spare parts like UV lamps, ballasts, and sensors. We offer maintenance contracts and are committed to supporting the long-term operational life of your equipment.
