The Classic Case
Badanjilin Desert Drinking Water Project: Faced with complex geomorphology and undulating pipeline engineering, Donghong Pipeline Industry expertly designed the project to solve the pressure discrepancies and connection challenges of different pipelines. By leading the installation and acceptance phases, we achieved a 30% cost saving. From water source to end supply, we ensured the strontium-rich 'healthiest water' quality remained unchanged, benefiting 300,000 residents in the desert with safe, eco-friendly, and healthy water.
Pipe for Yangzhou Shipyard Ship
Reinforced Polyethylene Pipe in Shipbuilding: Our PE pipes, with attributes like light weight, high strength, corrosion resistance, and non-toxic hygiene, have become indispensable in shipbuilding. They are ideal for drinking water, ballast water, air permeability, and domestic wastewater systems due to their easy and quick installation, excellent sealing performance, and leak-free operation.
Urban and Rural Water Supply Integration Project.
This ambitious project, with an investment of hundreds of millions of dollars, secures the drinking water safety for hundreds of thousands. By providing a comprehensive solution for village and town water coverage, we significantly improved rural drinking water quality standards and achieved a 100% water penetration rate. Donghong Pipeline was chosen as the project leader due to our robust 20-year track record and thousands of successful cases. Our commitment to quality and social responsibility makes us the ideal choice.
