Thermoplastic large-pipe-diameter polytetrafluoroethylene thin-wall pipe

Abstract

Disclosed is a thermoplastic large-pipe-diameter polytetrafluoroethylene thin-wall pipe which comprises a thin-wall pipe body. The thermoplastic large-pipe-diameter polytetrafluoroethylene thin-wall pipe is characterized in that the inner diameter of the thin-wall pipe body is 50-1000mm, and the wall thickness is 0.5-3mm. The thermoplastic large-pipe-diameter polytetrafluoroethylene thin-wall pipe has the advantages that requirements in use of large-pipe-diameter pipes with the inner diameters of 50-1000mm, thermal composite rollers or rollers for printing and the like can be met, performance of the large-pipe-diameter pipes, the thermal composite rollers or the rollers for printing can be improved, using cost of the thermoplastic large-pipe-diameter polytetrafluoroethylene thin-wall pipe can be effectively lowered, and the service life of the thermoplastic large-pipe-diameter polytetrafluoroethylene thin-wall pipe can be prolonged. The thermoplastic large-pipe-diameter polytetrafluoroethylene thin-wall pipe can be applied to industries like chemical engineering and machinery.

Description

technical field [0001] The invention relates to a thermoplastic polytetrafluoroethylene pipe, in particular to a thermoplastic polytetrafluoroethylene thin-wall pipe with a large diameter. Background technique [0002] Because PTFE has excellent chemical stability, corrosion resistance, sealing, high lubrication and non-stickiness, electrical insulation and good aging resistance, high temperature and low temperature resistance, it can be used at temperatures from -250°C to +260°C Under the long-term work, it has been used in many fields such as chemical industry and machinery. In particular, PTFE has heat resistance and chemical resistance, and can be lined in pipelines that transport corrosive gases or liquids under high temperature conditions. For this reason, the inner wall of the pipeline is lined with PTFE tubes, and its service life. However, although there are many manufacturers of PTFE pipes in China at present, the maximum inner diameter of PTFE pipes can only be ...

AI Technical Summary

Problems solved by technology

However, although there are many manufacturers of PTFE pipes in China at present, the maximum inner diameter of PTFE pipes can only be about 30mm, and there is no product with a large diameter, that is, an inner diameter of 50mm or more. The thickness of the PTFE pipe wall increases with the increase of the inner diameter of the pipe. The wall thickness of the pipe with an inner diameter of 15mm-30mm is generally 1.5mm-2mm, which increases the cost of use and is also limited by the scope of application. rather than meeting the needs of the market
