Rubber joints are often used in petroleum, chemical, smelting and other pipeline lines and pump valve pipelines. This product compensates for displacement in the axial, transverse and angular directions of the pipeline through its own good elastic deformation, and has a large amount of compensation per unit area. Good bearing pressure, aging resistance, long service life and so on, and the installation of rubber joint can alleviate the bad influence caused by axial thrust of pipe, furthmore, the installation of rubber joint can effectively reduce the construction difficulty of pipe connection, Thus perfectly realized the effective docking of the pipeline.

As a professional manufacturer of rubber joints, Gongyi Xinli has been studying rubber joints for more than 20 years, and has a deep understanding of the development of rubber joints industry. Today, this article discusses the rubber joint industry history of several more significant production changes detailed.

The early rubber joint sphere was made of multiple flaps of rubber joints that were vulcanized as a whole. This is what we commonly call the Ying Mo production process, which is a complex production method. The pressure bearing property is also limited to a relatively small range. The biggest characteristic of this production process is that the inner wall of the rubber joint will have striped lines, which is the biggest appearance characteristic of the Ying Mo production process. This type of production process is now used only for larger size pipes. Later, the appearance of gas blowing mould production technology realized the development of rubber joint industry by leaps and bounds, and all the comprehensive properties of the products were realized very well. Large improvements, especially in pressure-bearing performance, basically improved by 20% to 30%, thus expanding the application of the product. After the rubber joint industry appeared the golden stage of development, the rubber joint production specifications, materials, limiting devices and sealing surface changes are to provide an important driving force for the long-term development of the entire industry.
