The Classic Case
Badanjilin Desert Drinking Water Project, complex geomorphology, engineering pipeline ups and downs, Donghong Pipeline Industry participated in the project design, successfully solved the pipeline engineering pressure of different pressure pipeline and the corresponding connection mode supporting program, and led the pipeline installation and acceptance, saving 30% of the project cost. From the source of water diversion to the end of the water supply, to ensure that the "healthiest water (strontium-rich)" water quality has not changed, so that 300,000 people in the desert area to drink safe, environmentally friendly, healthy water.
Pipe for Yangzhou shipyard ship
Reinforced polyethylene pipe is gradually used in shipbuilding.PE pipe has the advantages of light weight, high strength, corrosion resistance, non-toxic hygiene, easy and quick installation, good sealing performance of piping system, no leakage, etc. Its performance is in line with the more piping systems in shipbuilding, such as drinking water system, ballast water system, air permeability system, domestic wastewater (black water and gray water) system.
Urban and Rural Water Supply Integration Project.
This project investment of up to hundreds of millions of dollars, the relationship between hundreds of thousands of people's drinking water safety, a complete solution to the people's drinking water within the coverage of the villages and towns; the establishment of a sound operation of a sound management and maintenance mechanism; the rural drinking water quality standard rate increased significantly; the rate of water penetration to reach 100%, which is of great significance, the government can choose Donghong Pipeline as the project leader, looking at Donghong Pipeline's strong strength, more than 20 years and thousands of case experience, and Donghong people "adhere to the quality of social security pipeline responsibility" the origin of the mission. Case experience, and Donghong people "adhere to the quality, adhere to the responsibility of social security pipeline," the origin of the mission.
