Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of setting device, concretely relates to the ultra high molecular pipe reducing diameter setting device. BACKGROUND

[0002] Ultra high molecular pipe, full name is ultra high molecular weight polyethylene pipe, is a kind of high-performance pipe material made of ultra high molecular weight polyethylene (UHMW-PE). Ultra high molecular weight polyethylene is a kind of thermoplastic engineering plastics, and its average molecular weight is usually above 1.5 million, and some can reach 3-6 million. This high molecular weight endows the pipe with many excellent properties.

[0003] The wear resistance of ultra high molecular pipe is extremely outstanding, and its wear resistance is 4-7 times that of steel pipe, 6 times that of nylon 66 and 5 times that of polytetrafluoroethylene. This is because the ultra high molecular weight polyethylene molecular chain is intertwined, and the structure is compact, so the molecular chain is not easy to be damaged when subjected to friction. In material conveying, the use of ultra high molecular pipe can greatly prolong the service life of the pipeline and reduce the cost and time loss caused by frequent replacement of the pipeline.

[0004] When using ultra high molecular pipe, the adjacent pipe sections need to be connected, which requires one end of the ultra high molecular pipe to be reduced in diameter. Since the ultra high molecular pipe is a thermoplastic, it has typical thermoplastic characteristics, and will soften and melt when heated.
