管接头是管道与管道之间的连接工具，是元件和管道之间可以拆装的连接点。在管件中充当着不可或缺的重要角色，它是液压管道的两个主要构成部分之一。管接头用于仪表等直线连接，连接形式有承插焊或螺纹连接。主要用于小口径的低压管线，用于需经常装拆的部位、或作为使用螺纹管件管路的最终调整之用。相关产品快易优均有收录，结构形式宜采用金属面接触密封结构，垫片密封的结构形式通常用于输送水、油、空气等一般管路上，采用可锻铸铁材料制造。此外，使用要求与价格等也是选用时考虑的因素。
Pipe joint is the connecting tool between pipe and pipe. It is the connection point between components and pipes that can be disassembled and disassembled. It plays an indispensable role in the pipe fittings, which is one of the two main components of the hydraulic pipe. The pipe joint is used for linear connection of instruments, and the connection form includes socket welding or thread connection. It is mainly used for small diameter low-pressure pipeline, for the parts which need to be installed and disassembled frequently, or used as the final adjustment of threaded pipe fittings. The quick and easy excellent products are included. The structure should be metal contact sealing structure. The gasket sealing structure is usually used for conveying water, oil, air and other general pipelines. It is made of malleable cast iron. In addition, use requirements and price are also factors to be considered when selecting.
