The Classic Case
Badanjilin Desert Drinking Water Project: Navigating the complex geomorphology with engineering expertise, Donghong Pipeline Industry took part in the project design, successfully addressing the engineering pressures of varying pipeline systems and developing compatible connection methods. We led the pipeline installation and acceptance process, achieving a 30% cost saving. From the source of water diversion to the endpoint of water supply, Donghong ensured that the 'healthiest water (strontium-rich)' quality remained unchanged, providing safe, environmentally friendly, and healthy water to 300,000 desert residents.
Pipe for Yangzhou Shipyard Ship
Reinforced Polyethylene Pipe: A Revolutionary Choice in Shipbuilding. This type of pipe offers numerous advantages such as lightweight, high strength, corrosion resistance, non-toxic hygiene, and easy, quick installation. The exceptional sealing performance of the piping system ensures no leakage. Its superior attributes make it the ideal choice for various piping systems in shipbuilding, including drinking water, ballast water, air permeability, and domestic wastewater (both black and gray water) systems.
Urban and Rural Water Supply Integration Project
With an investment reaching hundreds of millions of dollars, this project significantly impacts the drinking water safety of hundreds of thousands of people. It offers a comprehensive solution for drinking water across villages and towns, establishing robust management and maintenance mechanisms. The quality standard rate of rural drinking water has drastically improved, with a water penetration rate of 100%. The government chose Donghong Pipeline as the project leader, recognizing our strong capabilities, over 20 years of industry experience, and thousands of successful cases. At Donghong, we are driven by our mission to 'adhere to quality and uphold the responsibility of social security pipelines.'
High-Standard Farmland Project: Donghong delivers a reliable and stable irrigation pipeline system tailored to local conditions, supporting the construction of high-standard farmland. Our solutions help foster new agricultural practices, enabling fertile land to yield more and better-quality crops.
