Rubber joint is composed of fabric reinforced rubber parts and loose metal flange, which is used for pipeline vibration and noise reduction, compensation displacement joint. It is a kind of pipeline joint with high elasticity, high airtightness, media resistance and weather resistance. Dongli strictly in accordance with the standards and quality requirements of raw materials, to eliminate the phenomenon of cutting corners, ~ standard that the raw materials of the products not only need new materials, but also need to ~ level of new materials.

Product Case

Application of single sphere limit rubber joint in Anyang eighth water plant

The installation of single sphere restriction rubber joints produced by Gongyi Dongli in Anyang Eighth Water Plant provides a strong guarantee for the stability of the construction of the project.On the morning of December 12, the foundation laying ceremony of the Eighth Water Plant in Anyang City, Henan Province was successfully held at the project site. Our people's livelihood projects, its groundbreaking is the city to promote the construction of urban public infrastructure, the implementation of water to benefit the people of a major initiative of the strategy. Construction of the eighth water plant, the rational use of the South-to-North Water Diversion water source, both work tasks, but also political responsibility, the work of the current generation, the benefits in the autumn. Relevant departments at all levels to take practical and effective measures to vigorously promote the construction of the eighth water plant, and strive to make the city's people drink sweet and tasty Danjiang water as soon as possible.

Tang Xiantai asked, the city's relevant functional departments to form a high degree of consensus, with a strong sense of responsibility, and make every effort to provide convenient services for the construction of the project. To think of the project, to help the project needs, to solve the project's difficulties, streamline procedures, to provide strong protection for the construction of the project, dedicated support for the project construction, and strive to create a favorable construction environment, and strive to complete the project and put it into operation in 2016.

It is understood that, as the city's South-to-North Water Diversion supporting projects of the eighth water plant is located in the South-to-North Water Diversion Main Canal No. 38 east of the mouth of the gate, west of the Beijing-Guangzhou Railway, the total design scale of 200,000 cubic meters / day, a project design scale of 100,000 cubic meters / day, covering an area of 80 acres, with a total investment of 320 million yuan. The city's eighth water plant is an important basic facility for safeguarding and improving the livelihood of our people, and its construction is of great significance to further enhance the city's public water supply capacity, expand the scope of water supply, safeguard the safety of urban water supply, and promote the city's sustainable economic and social development. Gongyi Dongli, as the main supplier of single sphere restriction rubber joints for pipeline fittings of this project, is proud and honored to participate in the construction of this important project which benefits six million people.
