The Classic Case
Badanjilin Desert Drinking Water Project: In this project, Donghong Pipeline Industry overcame the complexities of the desert's geomorphology, tackling the challenges of varied pipeline pressures and developing appropriate connection solutions. Our involvement spanned from the design phase to installation and acceptance, ultimately saving 30% of the project's cost. Ensuring that the strontium-rich, healthiest water quality remained unchanged from source to supply, we provided 300,000 desert residents with access to safe, environmentally friendly, and healthy drinking water.
Pipe for Yangzhou Shipyard Ship
Reinforced polyethylene pipes are increasingly favored in shipbuilding for their outstanding properties. These PE pipes boast light weight, high strength, corrosion resistance, non-toxicity, and hygienic benefits. They also feature easy and quick installation with excellent sealing performance, ensuring no leakage. Such attributes make them highly suitable for various shipboard systems, 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 running into hundreds of millions of dollars, this project is pivotal for ensuring the drinking water safety of hundreds of thousands of residents. By delivering a comprehensive solution for water supply across villages and towns, we significantly improved rural drinking water quality standards. Achieving 100% water penetration, this project underscores its immense importance. The government selected Donghong Pipeline as the project leader, recognizing our robust capabilities, 20+ years of expertise, and our unwavering commitment to the quality and social security of pipelines.
