Description

Technical Field

[0001] The utility model relates to the technical field of polytetrafluoroethylene pipe processing, in particular to a steel-lined polytetrafluoroethylene pipe flanging device. Background Art

[0002] PTFE tube is a tubular material made of polytetrafluoroethylene. It is usually used for fluid medium transportation in the fields of chemical, petroleum, pharmaceutical, food, aerospace, environmental protection, etc. PTFE tube has high temperature resistance and pressure resistance, and can be used for a long time in the temperature range of -190℃~260℃. The friction coefficient of the fluid in the tube is low, and the transportation process is smooth. In addition, it has excellent flame retardant and insulation properties, and is suitable for various chemicals such as acids, alkalis, salts, strong oxidants and organic solvents.

[0003] Steel-lined PTFE pipe is a pipe with a special structure, usually composed of two parts: the outer layer is a steel pipe (usually stainless steel), and the inner layer is lined with PTFE material. PTFE material is a high-temperature, corrosion-resistant plastic, also known as polytetrafluoroethylene (PTFE), which has excellent chemical stability and lubricity. The design structure of this pipe gives it the strength and pressure resistance of steel pipe, while the PTFE material in the inner layer provides corrosion resistance and non-stick properties. This combination makes steel-lined PTFE pipe perform well in some special industrial fields, especially in the chemical industry and high temperature and high pressure environments.

[0004] In order to enhance the mechanical properties of the steel-lined polytetrafluoroethylene pipe end, prevent damage and leakage of the pipe and facilitate the installation of the pipe, the polytetrafluoroethylene pipe needs to be flanging.
