Product Description
Trenchless Sewer Rehabilitation with Daoyunai UV Liner ranging DN100-DN2000
The Daoyunai UV Liner is an advanced trenchless technology designed to rehabilitate aging or damaged sewer pipelines without the need for traditional excavation. It utilizes ultraviolet (UV) light-cured-in-place pipe (CIPP) technology, offering a fast, efficient, and environmentally friendly method of pipe repair. This technique suits urban environments where surface disruption must be minimized.
Constructed from high-strength fiberglass and UV-reactive resin, the Daoyunai UV Liner is engineered for durability, chemical resistance, and long-term performance. Once inserted into the pipeline, the liner is inflated to fit the interior of the existing pipe and then cured using UV light. This process significantly reduces curing time compared to traditional steam or hot water methods, allowing for rapid installation — often within a few hours.
One key advantage of the Daoyunai UV Liner is its seamless, jointless structure, which eliminates points of failure like leaks or root intrusion. It also improves hydraulic performance by restoring the pipe's structural integrity and smooth internal surface.
This solution is ideal for municipal, industrial, and commercial applications, offering a cost-effective and low-disruption alternative to full pipe replacement. With a service life exceeding 50 years, the Daoyunai UV Liner represents a smart investment in infrastructure longevity, sustainability, and operational efficiency for modern sewer systems.
