Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pipe connection, more particularly to a sealing sleeve and pipeline. BACKGROUND

[0002] The current traditional composite pipe (such as PE pipe) sealing method mainly adopts sealing ring sealing to prevent rust caused by direct contact with water after cutting production, and although the sealing ring sealing can meet the basic requirement of sealing, its limitations cannot be ignored. Specifically, after sealing with the sealing ring, the inner wall of the pipe is often rough and uneven during the welding forming process, and burrs are easily generated. More importantly, after the pipe is connected, the outer wall will have a curling protrusion that is obviously higher than the pipe wall. This protrusion not only affects the appearance of the pipe, but also may affect the sealing performance of the pipe. In order to solve this problem, special turning processing is required to remove the excess HDPE curling, and this additional process not only thins the fusion layer, but also may cause the problem of water stringing and expansion of the reinforcing layer of the pipe, reducing the strength and durability of the pipe, and increasing the operation process, reducing the overall construction efficiency.
