Daoyunai-Leading Manufacturer of Trenchless Pipe Inspection and Rehabilitation
Daoyunai specializes in the research, development, and manufacturing of advanced sewer pipeline inspection and trenchless rehabilitation equipment and materials for underground municipal drainage systems.
Our CCTV pipe inspection systems utilize high-definition video technology and intelligent robotics. These inspection robots navigate through pipelines, transmitting real-time data to the control unit. The system captures detailed visual and structural information of the pipe interior, enabling accurate condition assessment and comprehensive reporting.
Our trenchless UV curing rehabilitation equipment integrates all core components into a single compact system, including a smart control unit, cable reels, multiple pipe diameter light rigs, advanced LED and high-pressure mercury UV lamp technology, high-capacity air compressors, and Japanese-made generators. The system ensures stable operation and efficient UV light penetration for reliable in-situ pipe lining.
We also provide high-performance CIPP (cured-in-place pipe) liner materials, composed of fiberglass fabric and resin-impregnated flexible liners, fully customizable in length, thickness, and diameter to meet a wide range of project requirements.
As of 2025, Daoyunai has sold over 350 kilometers of liner materials, more than 20 sets of UV curing systems, and over 400 sets of video pipe inspection devices—serving municipalities and contractors worldwide with reliable trenchless technology solutions.
