Project Background This key provincial long-distance water diversion project of Fujian in 2026 applies DN2800 extra-large-diameter pipelines to optimize regional water resource allocation. The buried pipeline crosses hills and river crossings with complicated landforms for high-flow water conveyance. Ultra-high-grade anti-corrosion system is required to secure full-life-cycle safe operation of this huge water-conveyance pipeline.
Customer Pain Points Extra-large-diameter pipes own huge coating area, putting strict requirements on powder batch consistency and spraying uniformity. Alternating humidity and temperature along long-distance complex routes may trigger coating peeling and aging. As a major national water-conservancy project, it demands full traceable quality certificates and long-term weather-resistance data for acceptance.
Our Solution We provided high-weather-resistance full-life anti-corrosion epoxy powder dedicated for super-large water-conveyance pipelines. It features favorable low-temperature leveling, uniform film thickness and superior adhesion, perfectly fitting spraying of extra-large-diameter pipes. Optimized anti-aging and anti-peeling formula adapts to long-term service across diverse terrains. Full-process batch traceability reports and third-party test reports are offered to meet strict acceptance standards for key water-conservancy projects.
Project Results A total of 36 tons of special anti-corrosion epoxy powder was delivered. Uniform and defect-free coating meets design requirements for long-distance high-flow water delivery. The project successfully passed quality acceptance. We are appointed as designated anti-corrosion material supplier for follow-up supporting pipe-network works.
