KDF flange type rubber joint is an improved version of KXT single ball rubber joint according to the needs of users, which can withstand relatively large displacements and pressures. More importantly, the pull-out condition of the single-ball rubber joint under excessive pressure was improved. The improved large flanged rubber joint sealing surface is consistent with the outer diameter of the flat welding flange, and the sealing surface is also drilled. The rubber joint is connected with the pipeline as a whole, thereby improving the stability of the use of the rubber joint. The product has high internal density, can withstand high pressure, and has good elastic deformation effect.
KDF flanging rubber joints are made of fabric-reinforced rubber parts and flat unions, which are used to reduce vibration and reduce noise in pipes and compensate displacement. It is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. In strict accordance with international standards and raw material quality requirements, to eliminate the phenomenon of cutting corners, environmental protection standards that product raw materials not only need new materials, but also environmentally friendly new materials.

The rubber joint is connected with the pipeline as a whole, thereby improving the stability of the use of the rubber joint. The product has high internal density, can withstand high pressure, and has good elastic deformation effect. Rubber joints are made of fabric-reinforced rubber parts and loose metal flanges, which are used for pipe vibration isolation, noise reduction and compensation for displacement. It is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. Gongyi Xinli strictly abides by international standards and quality requirements of raw materials, and eliminates the phenomenon of cutting corners. The environmental protection standard means that the raw materials of the product not only need new materials, but also environmentally-friendly new materials.
The cooperation project between Gongyi Xinli and Jilin Chemical Industrial Park's flanged single-sphere rubber joint was officially launched yesterday. Five chemical projects, including a long-chain dibasic acid with a total investment of 11.3 billion yuan, officially entered the Jilin Chemical Industry Park on January 24 and became a new member of this family. Among these new projects, the big highlight is the construction project of biochemical park. This project uses abundant paraffin products and the complete chemical industry system in the park as resources to build a 15,000 tons / year long chain dibasic acid project, a 120,000 tons / year engineering plastics project, and hot melt adhesives, musk, and advanced powder coatings. Chain binary acid deep processing series project. The first-phase project planned to start in March will mainly build two long-chain dibasic acid production lines. Downstream projects will start construction after the long-chain dibasic acid is reached. After the biochemical park project is completed and put into operation, the annual output value is expected to reach 20 billion yuan. In addition, after the completion of the 400,000-ton / year ABS expansion project of Jilin Petrochemical, the production capacity will reach 580,000 tons. Relying on sufficient ABS raw materials, the investor intends to build a deep processing project in Jilin Province with an annual output of 200,000 sets of automotive plastic parts, 200,000 sets of televisions and 100,000 sets of washing machine casing plastics, which will effectively extend the ABS industry chain. to satisfy the market's needs.
It is understood that the construction of five chemical projects in Jilin Chemical Park signed a contract with Gongyi Xinli for a flanging single-sphere rubber joint of 60,000 yuan. Gongyi Xinli has won many tenders with its excellent product performance and strong enterprise strength. Among them, I believe that in the near future, it will be a new star in the pipe fittings industry.
