The Classic Case
Badanjilin Desert Drinking Water Project: Addressing intricate geomorphological challenges with unparalleled engineering prowess, Donghong Pipeline Industry was indispensable in the project's design. We adeptly managed the varying pipeline pressures and their intricate connections. Spearheading the pipeline installation and acceptance, we realized an impressive 30% cost reduction. From water diversion to end supply, our commitment ensured the delivery of 'healthiest water (strontium-rich)' remained pristine, providing safe, eco-friendly, and healthful water to 300,000 desert inhabitants.
Pipe for Yangzhou Shipyard Ship
Reinforced polyethylene pipes are revolutionizing shipbuilding. Renowned for their lightweight, high strength, corrosion resistance, non-toxicity, hygiene, ease of installation, and superior sealing performance, these pipes ensure zero leakage. These exceptional characteristics make them ideal for various shipbuilding piping systems, including drinking water, ballast water, air permeability, and domestic wastewater (black and gray water) systems.
Urban and Rural Water Supply Integration Project
This transformative project, boasting investments in the hundreds of millions of dollars, is vital for the drinking water safety of hundreds of thousands. It delivers a holistic solution to the drinking water needs of villages and towns, establishing an efficient management and maintenance framework. The project's success markedly elevated rural drinking water quality standards, achieving 100% water penetration. The government selected Donghong Pipeline as the project leader, lauding our substantial expertise, over 20 years of experience, and a multitude of successful cases. Our guiding mission, 'Adhering to quality and the responsibility of social security pipeline,' propels us forward.
