Card sleeve type pipe joint installation method and instructions

1. Saw a suitable length of seamless steel pipe to remove burrs at the port. The end face of the pipe should be perpendicular to the axis with an angular tolerance of no more than 0.5°. If the pipe needs to be bent, the length of the straight section from the end face of the pipe to the curved portion must not be less than three times the length of the nut. Put the nut and the ferrule on the seamless steel pipe. Pay attention to the direction of the nut and the ferrule. Do not reverse it. Apply lubricant to the pre-assembled joint body threads and ferrules, insert the tube into the joint body (the tube must be inserted all the way) and tighten the nut by hand. Tighten the nut until the ferrule catches the tube. This turning point can be felt (pressure point) by the increase in tightening torque. After reaching the pressure point, tighten the compression nut 1/2 turn. Remove the pre-assembled joint body and check the embedding of the ferrule edge. The visible protruding strip must fill the space of the ferrule end face. The ferrule can be rotated slightly but not axially. In the final installation, apply the lubricating oil and the compression nut to the thread of the joint body in the actual installation until the sensible tightening force increases, and then tighten the 1/2 turn to complete the installation.

Second, the card sleeve joint installation instructions: the card sleeve joints should be cleaned inside and outside the joint interface with the ferrule joints at the installation, the nozzle must be polished flat, the surface can not have burrs and bumps. Moreover, the joint between the take-over and the ferrule joint should not be bent, otherwise the joint between the ferrule joint and the steel pipe may be leaked. The steel pipe at both ends of the connected ferrule joint is preferably made of a uniform material pipe to prevent leakage. After the steel pipe is embedded in the ferrule joint body, the strength of starting the fastening of the ferrule should not be too large. The ferrule should be screwed to the end of the thread or 2/3, and the ferrule should be fastened with a wrench.

Summary: The above is about how to install the ferrule connector and the ferrule connector installation needs to know those places, if it will not be installed for the first time, slowly, it will always succeed. There are also engineers who like to use the ferrule joint because it is very strong, and the ferrule joint has better sealing performance. Generally, the ferrule joints are used in refining, light industry, national defense, etc., and even mechanical engineering and machine tool equipment are also useful for ferrule joints. Finally, make sure the ferrule fittings are securely installed.
