Project Background Carried out in Jiangchuan District, Yunnan in 2026, this key urban-rural water-supply upgrading project includes water-plant renovation and replacement of aged township pipe networks (DN200-DN1000). Located in subtropical humid zones, pipelines are buried in weakly-acidic moist soil, calling for safe and durable drinking-water-grade anti-corrosion materials.
Customer Pain Points Year-round humid-rainy climate and weakly-acidic soil easily cause electrochemical corrosion to buried pipelines. Ordinary coatings tend to blister and peel under long-term humid conditions. Scattered construction sites and tight schedules demand stable batch supply, fast delivery and complete drinking-water-safety certification for livelihood-project filing.
Our Solution We customized humid-climate-resistant drinking-water-grade epoxy powder for subtropical corrosive environments, with enhanced acid-resistance, moisture-resistance and anti-blistering performance. Stable curing property ensures good constructability for multi-site scattered construction. Flexible phased batch delivery matches tight project schedules. Complete hygiene test reports and national-standard qualification documents are provided for filing and acceptance.
