![]() ![]() Excessive lateral force may cause loose sealing.ĭ. When connecting the pipeline, it should be done at one time and avoid multiple disassembly, otherwise the sealing performance will be deteriorated.Ģ. installing a compression fitting on copper pipeĪ: According to the requirements, the pipes that need pickling should be pickled first ī: Use a sawing machine or a special pipe cutting machine to cut the pipe according to the required length. ![]() As a result, the sealant is flushed into the hydraulic system, causing malfunctions such as clogging of the internal holes of the hydraulic components.ī: When connecting the pipeline, make sure that the pipe has enough deformation margin to avoid stretching the pipe.Ĭ: When connecting pipelines, avoid lateral force. In order to obtain a better sealing effect, some people apply sealant on the ferrule. If the ferrule is severely deformed during pre-assembly, the sealing effect will be lost.Ī: It is forbidden to add packing such as sealant. ![]() The tightening force of ф6-1 ferrule is 64-115N, ф16mm is 259N, and ф18mm is 450N. When the pipeline is connected, it is assembled according to the specified tightening force. If the pipe deflection is too large, the seal will fail.ĭ: The preloading force should not be too large so that the inner blade of the ferrule just fits into the outer wall of the pipe, and the ferrule should not be significantly deformed. After the pipe is sawn, it should be smoothed on a grinding wheel and other tools, and the burrs should be removed, cleaned and blown with high-pressure air before use.Ĭ: When pre-installing, try to maintain the coaxiality between the pipe and the joint body. The correct way is to use what kind of joint body to connect one end of the pipe, and the corresponding connection end is pre-assembled with the same type of joint, so as to avoid leakage problems to the greatest extent.ī: The end of the pipe should be flush. We found that even if it is a batch of goods from the same manufacturer, the depth of the tapered holes on these types of joint bodies are often different, resulting in leakage, and this problem is often overlooked. There are mainly ferrule-type straight-through pipe joints, ferrule-end straight-through connectors, ferrule-type three-way pipe joints, etc. The specific method is to use a joint as the mother body to press the nut and ferrule onto the pipe. Small pipe diameter compression fitting sizes can be pre-assembled on the vise. A special pre-device is generally required. This article mainly elaborates on the two most important aspects of compression fitting for galvanized pipe to avoid leakage, as well as precautions。Ī: The most important part of the pre-installation of the fitting compression joints directly affects the reliability of the seal. ![]()
