"One Belt and One Road" Pakistan Thar Coalfield.
Demonstrating the international service capabilities of Donghong Pipeline.
Pakistan's Thar Coalfield is a priority project of the "China-Pakistan Economic Corridor Energy Planning" and a key project of the countries along the "Belt and Road". Donghong's plastic-coated and weighted anti-corrosion steel pipes were screened at all levels and finally selected into the Thar Open-pit Coal Field. As the vanguard of the "One Belt, One Road" initiative, Donghong Pipe Industry supports China's national strategy with practical actions.
The Han-to-Wei River Diversion Project.
This project is an overall water resource allocation project in Shaanxi Province and a key national promotion project from 2020 to 2022. Using Φ3448mm anti-corrosion steel pipes from Donghong Co., Ltd., after the completion of the project, the water shortage situation in the water-receiving areas of Shaanxi Province has been significantly improved, and the beneficiary population will reach 14 million. Through the support of high-quality water conservancy development, it not only enriches the healthy life of thousands of households, but also provides a source of power for cities to improve river water quality and help ecological restoration.
Hubei Province Xiaogan Urban Water Supply System Raw Water Relocation Project.
The total investment of this project is 1.317 billion yuan. It is a short-term project to improve urban infrastructure and a livelihood project to ensure the safety of drinking water for local residents. The project uses Donghong's DN1600mm plastic-coated steel pipes. Once completed, it will further improve Xiaogan's water resource carrying capacity for high-quality development and provide a strong guarantee for building an important node city in the Wuhan metropolitan area.
Nishan World Civilization Forum supporting facilities project.
This project mainly uses the Si River main stream reservoir and gate dam to adjust and store water to replenish the Nishan Reservoir) and regulate the ecological environment. Nishan Reservoir is a reservoir mainly for flood control, but also for comprehensive utilization such as irrigation and breeding. Due to dry weather, upstream interception and other reasons, its ability to regulate and store water has gradually weakened. The implementation of this project can effectively control the water volume of the downstream river, restore the water surface of the reservoir, form a water system landscape, transport water from the Si River to the reservoir area, optimize and regulate the ecological environment, provide a good environment for the Nishan World Cultural Forum, and have a positive impact on the ecology of the tourist city Regional regulation is of great significance.
