Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to a polyethylene pipeline butt joint tool. Background Art

[0002] Polyethylene pipe, referred to as PE pipe, is a pipe with polyethylene resin as the main raw material. Polyethylene pipe is made by extrusion molding process. It is widely used, mainly for indoor and outdoor low-temperature water supply pipes, buried pipes and thermoplastic plastic round pipes without internal pressure. Polyethylene pipe is widely used in various fields due to its excellent chemical corrosion resistance, good mechanical properties and durability.

[0003] When processing polyethylene pipes, it is often necessary to butt-join two sections of pipes. Workers heat and melt the butt ends of the pipes, butt-join and press the pipes, and complete the butt-joining function after cooling and shaping. When welding large polyethylene pipes, manual operation is difficult due to the large size of the pipes, and the natural cooling after welding takes a long time, resulting in low processing efficiency. Therefore, we propose a polyethylene pipe butt-joining tool. Utility Model Content
