Daoyunai 2025 Sales Soar: A Testament to Leadership in Trenchless Pipeline Rehabilitation

Daoyunai, a premier manufacturer and supplier of advanced trenchless pipeline rehabilitation technologies, today announces a year of remarkable sales growth and market expansion for 2025. The company's performance, marked by significant increases across its core product lines, underscores its pivotal role in supporting global infrastructure maintenance and sustainable urban development. With a strong backlog of current orders, Daoyunai enters 2026 with robust momentum and heightened confidence.

The 2025 fiscal year has been exceptional for Daoyunai, demonstrating accelerating demand for its high-quality, non-disruptive pipeline repair solutions. The company's success is quantified by impressive figures that speak to both volume and capability:

• Cured-In-Place Pipe (CIPP) Rehabilitation Materials: Daoyunai supplied its state-of-the-art UV-cured liners for pipes ranging from DN150 to DN2000, covering a total length exceeding 320 kilometers. This substantial output facilitated efficient, long-lasting repairs for municipal and industrial networks worldwide. Furthermore, a 13-kilometer order is currently in production, highlighting continuous demand.
• UV Curing Equipment: Sales of Daoyunai's reliable and efficient light-curing units reached 32 systems in 2025, with 10 units currently in the delivery pipeline. This equipment is essential for the fast and effective installation of CIPP liners.
• Pipeline Inspection Crawlers: The company sold 350 advanced video inspection robots, crucial for accurate pipeline condition assessment. With 23 robots yet to be delivered from current orders, Daoyunai remains a trusted partner for diagnostic precision.

Daoyunai's success is built on a comprehensive portfolio designed to address the entire pipeline rehabilitation workflow.

1. CIPP Liner Materials for Large Diameters: Specializing in diameters up to DN2000, Daoyunai's liners offer structural strength, corrosion resistance, and long design life. The ability to handle such a wide range, including large-diameter pipes, positions the company as a #1 supplier for complex municipal and industrial projects.
2. Integrated UV Curing Technology: Daoyunai's curing devices are engineered for reliability, uniform curing, and user-friendly operation. Their synergy with Daoyunai liner materials ensures optimal performance, reducing project time and risk for contractors.
3. High-Resolution Inspection Crawlers: Before any repair, accurate diagnosis is key. Daoyunai's crawlers provide clear, locatable defect identification, enabling targeted rehabilitation strategies and maximizing the return on infrastructure investment.

The current backlog—13km of liners, 10 curing units, and 23 inspection crawlers—is a powerful indicator of sustained market trust and projected growth. This pipeline of active orders not only reflects Daoyunai's production capacity but also the industry's growing preference for trenchless methods championed by the company. It demonstrates that clients consistently choose Daoyunai for critical infrastructure projects.
