The Classic Case
Badanjilin Desert Drinking Water Project: Tackling complex geomorphology with engineering expertise, Donghong Pipeline Industry played a crucial role in designing the project, solving the pressure challenges of varying pipeline pressures and their corresponding connections. Leading the pipeline installation and acceptance, we achieved a 30% cost savings. From water diversion to end supply, we ensured the 'healthiest water (strontium-rich)' remained unchanged, bringing safe, eco-friendly, and healthy water to 300,000 desert residents.
Pipe for Yangzhou Shipyard Ship
Reinforced polyethylene pipe is being increasingly integrated into shipbuilding. PE pipes boast attributes like light weight, high strength, corrosion resistance, non-toxicity, hygiene, ease of installation, and excellent sealing performance, ensuring no leakage. These qualities align perfectly with 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 monumental project, with investments in the hundreds of millions of dollars, is pivotal for the drinking water safety of hundreds of thousands of people. It provides a comprehensive solution for the drinking water needs of villages and towns, establishing an efficient management and maintenance mechanism. The project's success significantly raised rural drinking water quality standards and achieved 100% water penetration. The government selected Donghong Pipeline as the project leader, recognizing our formidable strength, 20+ years of experience, and thousands of successful cases. Our mission, 'Adhering to quality and the responsibility of social security pipeline,' drives us.
