What is the impact of the card sleeve joint on modern industry? The simple comparison of the domestic and foreign card sleeve joint also makes a simple introduction for you. About the impact of the card sleeve joint on modern industry and the comparison, the small series table will sort out the relevant content for you.
Jacket joints affect modern industry
With the rapid development of petroleum, chemical industry, natural gas, oil refining and other industries, the product quality requirements are increasingly strict today, control facilities for the quality of these liquid and gaseous products play a crucial role, the appearance of bayonet joint makes the product sealing performance greatly improved. There is no need for welding when the bayonet joint is connected with the steel pipe, which is conducive to fire prevention, explosion protection and aerial work, and can eliminate the disadvantages caused by careless welding. Therefore, it is a relatively advanced connecting piece in the pipeline of automatic control devices of oil refining, chemical industry, petroleum, natural gas, food, pharmaceutical, instrument and instrument systems.
卡套式接头国外一般分为低压、中压和高压LL,L,S三个系列(分别为1 OMPa,10一25MPa, 25一63MPa。卡套式管接头属硬管管接头，按照卡套结构形式，目前国外产品主要有单卡套系列和双卡套系列，其中单卡套系列分为单刃口卡套和渐进式多刃卡套;按卡套的密封形式分，有传统卡套接头的硬密封方式和新式的卡套连接加弹性密封方式。
Comparison of domestic and foreign products of bayonet joint
Bayonet connectors are generally divided into low pressure, medium pressure and high pressure LL,L,S series abroad (respectively 1 OMPa,10 a 25MPa, 25 a 63MPa). Bayonet type pipe joint belongs to hard pipe joint. According to the structure of bayonet type, at present, foreign products mainly include single bayonet type series and double bayonet type series, among which single bayonet type series is divided into
single-blade bayonet type and progressive multi-blade bayonet type. According to the sealing form of the card sleeve, there are the hard sealing way of the traditional card sleeve joint and the elastic sealing way of the new card sleeve joint.
The leakproof of bayonet type joint is closely related to the manufacturing quality (especially the design of bayonet and the inherent quality of bayonet), the precision of steel pipe and the assembly quality, which requires good cooperation between the manufacturer and the user. Foreign countries generally have dedicated end processor, chamferer and preloader, control tightening torque, high assembly quality, to the
greatest extent to avoid the leakage problem caused by the human factors of clip sleeve pipe joint.
