    product description

    KDF-F flanging rubber soft joint is an improved version of KXT single ball rubber joint according to user needs, 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 modified large flanged rubber joint has the same sealing surface as 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 pipeline operation.

    Product advantages

    It is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. High internal density, can withstand high pressure, and good elastic deformation effect.
    Soft rubber joints are composed of fabric-reinforced rubber parts and loose metal flanges, which are used to reduce vibration and noise in pipes and compensate displacement. 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. Rubber joints are also known as flexible rubber joints, pipe shock absorbers, shock absorbers, and soft joints.

    Due to the good comprehensive performance of flexible rubber flexible joints, it is mainly used for the lifting and transportation of raw water and sewage, feed water and cooling circulating water for thermal power plants, metallurgy industry, condensate water, pipeline transportation of chemicals in chemical industry, petrochemical Cooling, dilution and flexible connections between long and short distance pipelines in other industries. Because rubber has high abrasion resistance, it is also suitable for the transportation of granular and powdery materials and vapors in all industries.

    Classic Case

    Application of Flanged Single-Sphere Limit Rubber Joints in Zhundong Industrial Belt Project

    The use of flanged single-sphere limit rubber joints has played an important role in the construction of the Zhundong Industrial Zone project, and has provided an excellent supporting role for the development of the Zhundong Industrial Zone. The person in charge of the Xinjiang Changji Prefecture Coal Chemical Industry Office introduced that five special sub-plans including water supply and drainage, transportation logistics, power grid structure, land use, and greening supporting the functional layout of the industrial zone have passed approval. The first phase of the infrastructure was completed in 2009, with a total investment of 3.5 billion yuan. The 138-kilometer Zhundong Highway has been completed and opened to traffic, and a circular transport corridor for the industrial zone has been formed. The railway from Urumqi North Station to Zhundong has also been put into operation, with an annual freight capacity of 15 million tons.

    It is understood that this year is the construction year of the Zhundong Industrial Belt Project in Changji Prefecture, Xinjiang. It is planned to start 12 projects. Among them, there are 4 coal mine projects and strive to exceed 30 million tons of coal output; 3 coal power projects, construction of 2 600 MW thermal power plants, and 1.2 million kW thermal power plants; 5 coal chemical projects, completion of construction of 1.3 billion cubic meters of coal Natural gas project, three 4 billion cubic meters of coal-to-natural gas project, 300,000 tons of coal tar to diesel engineering project. It is believed that in the near future, the figure of Xinli flanging single-sphere limit rubber joint will appear in more pipeline projects, providing more efficient pipeline compensation for more projects. Welcome everyone to come to buy.
