Why does the pipe joint leak?
Answer:
The steel pipe does not top to the edge of the positioning edge of the joint body, resulting in insufficient steel pipe cutting into the jacket, and no sealing line is formed
Workers do not install according to the provisions: for example, the end face of the steel pipe is not vertical, and there are burrs on the surface of the steel pipe.
In the installation process, the steel pipe skew leads to the non-uniform cutting of the jacket, resulting in part not forming enough sealing line
The size of steel pipe is small and the quality of steel pipe is not high.
Answer:
in the installation process, the skew of the steel pipe leads to uneven cutting of the jacket, resulting in greater tangential friction
Do not apply oil in the specified place
Labor saving method: put a little oil on the thread part of the joint body, and put a little oil on the contact surface of the sleeve and the 24 degree cone, and the contact surface of the sleeve and the compression nut.
