Core Technologies Displayed at Booth P4
Modern municipal drainage networks require fast, reliable repair methods that eliminate the high costs and surface destruction of conventional open-cut trenching. At Booth P4, Daoyunai Energy Saving Technology Limited highlighted three core technology portfolios designed for trenchless rehabilitation:
- UV CIPP Liners: Resin-impregnated flexible lining tubes engineered to form a continuous structural inner pipe inside damaged underground sewers and storm drains.
- UV & LED Curing Systems: Advanced light sources designed for rapid photopolymerization of liner resins, ensuring controlled curing rates without heating large volumes of water or steam.
- CCTV Pipeline Inspection: High-definition inspection crawler systems built to navigate subterranean pipes, capturing real-time video footage of cracks, joint displacement, corrosion, and structural anomalies.

Frontline Market Insights & Technical Workflows
Discussions with municipal contractors during the Istanbul event highlighted increasing demand for integrated diagnostic-and-repair solutions. Urban density in historical and commercial districts limits the feasibility of excavation. Utilizing UV CIPP equipment in combination with CCTV crawlers provides an end-to-end workflow:
1. Diagnostic Assessment: CCTV inspection crawlers are deployed prior to rehabilitation to determine exact defect positions, clean pipe geometry, and assess structural integrity.
2. Liner Installation: The UV CIPP liner is pulled into the target pipe section using low-friction protective glide films to shield the outer membrane from internal wall abrasions.
3. Light Curing Execution: Once pressurized and inflated, UV or LED light heads travel through the liner length at regulated speeds, triggering rapid resin curing.
4. Quality Verification: Post-curing CCTV video inspections confirm wall thickness uniformity, surface smoothness, and complete sealing along the rehabilitated section.
Daoyunai Energy Saving Technology Limited remains committed to supporting global partners with robust trenchless rehabilitation equipment and high-definition pipeline inspection crawlers.
