When installing the ferrule joint, the internal and external parts of the pipe joint connected with the ferrule joint must be cleaned. The pipe joint must be polished and smooth, and the surface must be free of burrs and uneven surfaces. Moreover, the embedding part of the nozzle and the ferrule joint should not be bent, otherwise it will cause leakage at the joint between the ferrule joint and the steel pipe. The steel pipes at both ends of the connected ferrule joint should be of uniform material, which can effectively prevent leakage.

After the steel pipe is inserted into the ferrule joint body, the force of tightening the ferrule should not be too strong. The ferrule should be tightened to the end of the thread or 2/3 gradually, and the ferrule can be tightened with a wrench.

Card sleeve type pipe joints-suitable for medium: oil, water, gas and other non-corrosive or corrosive media. Sealed pipe joints, equipped with aluminum-plastic pipes, have flexible specifications. After being connected to the pipeline, they have a firm and sealed connection It has good performance and other characteristics, so it is widely used in oil refining, chemical industry, light industry, textile, national defense, metallurgy, aviation, shipbuilding and other systems; it is also suitable for various hydraulic transmission pipelines such as mechanical engineering and machine tool equipment.
