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.
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.
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.
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.
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.
