[0002] Steel-lined PTFE pipe is made of ordinary carbon steel pipe as the matrix, lined with thermoplastic polytetrafluoroethylene plastic with excellent chemical stability, and processed by molding process. It is mainly used to transport highly corrosive media such as strong acids, strong alkalis, industrial salts and highly corrosive gases. It is an ideal pipeline for high-temperature and highly corrosive media.

[0003] At present, when manually installing lined polytetrafluoroethylene pipes, there are problems such as difficulty in flanging the flange sealing surfaces on both sides of the carbon steel pipe, low efficiency and unstable flanging quality, which seriously restricts the installation progress of lined polytetrafluoroethylene pipes.
