The Classic Case
Badanjilin Desert Drinking Water Project: Navigating the complex geomorphology and engineering challenges, Donghong Pipeline Industry expertly participated in the project design. We successfully addressed varying pipeline pressures and corresponding connection models, leading the pipeline installation and acceptance process. Our solutions saved 30% of the project cost. From the source of water diversion to the final water supply, we ensured that the 'healthiest water (strontium-rich)' quality remained unchanged, enabling 300,000 desert inhabitants to access safe, environmentally friendly, and healthy water.
Pipe for Yangzhou Shipyard Ship
Reinforced Polyethylene Pipe for Shipbuilding: As shipbuilding evolves, reinforced polyethylene pipes have become indispensable. PE pipes boast light weight, high strength, corrosion resistance, and non-toxic hygiene. Their ease of installation and excellent sealing ensure no leaks, making them ideal for various ship systems, including drinking water, ballast water, air permeability, and domestic wastewater systems (both black and gray water).
Urban and Rural Water Supply Integration Project.
Urban and Rural Water Supply Integration Project: With an investment of up to hundreds of millions of dollars, this project is crucial to the drinking water safety of hundreds of thousands of people. It comprehensively addresses drinking water needs across villages and towns. The project establishes a robust management and maintenance system, significantly enhancing rural drinking water quality standards and achieving a 100% penetration rate. The government selected Donghong Pipeline for its formidable strength, over 20 years of experience, and numerous successful case studies, underscored by our mission to 'uphold the quality and responsibility of social security pipelines.'
High-Standard Farmland Project: Donghong provides stable, supportive irrigation pipeline systems tailored to local conditions, aiding in the construction of high-standard farmland. This ensures that fertile land yields more and better quality grain, boosting new agricultural initiatives.
