Warmly congratulate our company

On October 25, 2019, the "New Large Diameter Insulating Joint" project developed by our company won the third prize of China Machinery Industry Science and Technology Progress Award jointly issued by China Machinery Industry Federation and China Mechanical Engineering Society.

According to the quality status of domestic insulation joints and the needs of the development of national pipeline engineering, our company has carried out the development and engineering application of "new large-diameter insulation joint products". The results have filled the gaps in the systematic research of domestic large-diameter insulation joints, formed new product standards, promoted the manufacturing level of the industry, and solved the problem of unstable performance of domestic large-diameter insulation joints.

The project has completed the appraisal of scientific and technological achievements of new products with representative specifications of 1.2 meters and 1.4 meters. A reliable and economical design and calculation method has been developed, and large-diameter, low-temperature (-45 ℃) fluorine rubber seals have been developed to meet the requirements of the product in low-temperature environment, making the product performance index and ultimate bearing capacity exceed those of foreign products and equivalent pipelines; at the same time, through the development and verification of special equipment to improve the manufacturing, quality assurance and mass production capacity of insulation joints, to achieve engineering applications, and achieved good product operation performance.
