管道配件中橡胶接头，橡胶软连接是需要带配对的，是否带配对是由管件的连接方式决定的。

比如橡胶软连接将两个管口连接起来，在左边的管口上焊接一片，参数要和橡胶软连接的参数相同，以方便对接，在管子上焊接的就是配对。不用配对的就需要焊接。

焊接有一个弊端那就是不易拆卸，因为与管子焊接在一起一旦需要拆卸就要把焊管的部分割开，才能取掉打开。

9299百瑞彩票安装这种油管接头，比较关键的是要控制好是管子端部的扩口。

否则如果扩口过大，就会影响到密封效果，甚至有可能产生裂纹。

具体来说这种接头的安装，是需要大家注意在拧紧管接头螺母时，紧固力矩要适度，拧紧时必须用力矩扳手。

Rubber joints and rubber soft connections in pipe fittings need to be paired. Whether to pair or not is determined by the connection mode of pipe fittings.

9299百瑞彩票For example, the rubber soft connection connects two nozzles, and one piece is welded on the left nozzle. The parameters should be the same as those of the rubber soft connection to facilitate docking. What is welded on the pipe is pairing. Those that do not need to be paired need to be welded.

9299百瑞彩票One disadvantage of welding is that it is not easy to disassemble, because once it is welded with the pipe, the part of the welded pipe must be cut off before it can be removed and opened.

9299百瑞彩票The key to installing this kind of tubing joint is to control the flaring at the end of the pipe.

Otherwise, if the flare is too large, it will affect the sealing effect and even crack.

9299百瑞彩票Specifically, for the installation of this kind of joint, we should first pay attention to the appropriate tightening torque when tightening the pipe joint nut, and the torque wrench must be used when tightening.

The second is to try to operate well at one time. If the copper pipe is disassembled and reassembled, it must be replaced with a new copper pipe, flared again and then installed.
