The purpose and common classification of high pressure tubing joints

　　First, the use of high-pressure tubing joints

　　 high pressure oil pipe joints are widely used in the coal industry and petroleum industry. In recent years, in the coal industry, some traditional steel wire braided hoses cannot meet the development of the industry well, which has given birth to the widespread use of high-pressure oil pipe joints in the coal industry. At the same time, high-pressure oil pipe joints have better safety and make people more assured . In the petroleum industry, long-distance oil pipelines are required, and the high-pressure oil pipe joints have good sealing properties, so they are favored by the petroleum industry.

　　Second, classification of high-pressure steel wire wound tubing joints

This kind of joint is composed of inner, middle and outer three layers of glue, and there are 2 to 6 layers of steel wire winding. The three layers of glue can protect the steel wire well and have enough strong support capacity, and it is not easy to be corroded. . It is generally used in scenarios such as mine hydraulic supports and oilfield development, and it is also common in some engineering manufacturing.

　　 Third, classification of high-pressure steel wire braided tubing joints

The biggest difference between this type of joint and the previous type is the manufacturing process of the tubing joint. In terms of structure, it also has a three-layer inner, middle and outer layer composed of synthetic rubber, which protects the medium, is corrosion-resistant, and has a certain supporting effect. It has three braided layers of steel wire, and the steel wire is used differently. This type of tubing joint is often used in the manufacture of some mining equipment and machine tools. It can be used normally in the temperature range of minus thirty degrees to fifty degrees above zero.
