Description

Technical Field

[0001] The invention relates to the technical field of steel lined fluorine pipe production, and more specifically to a molding device and a process thereof for steel lined fluorine pipes. Background Art

[0002] Steel-lined PTFE pipes, steel-lined polytetrafluoroethylene PTFE pipes and accessories enjoy the reputation of "plastic king" and have excellent temperature resistance and corrosion resistance. They are ideal conveying equipment for highly corrosive media such as nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine, aqua regia, mixed acid, bromide and other organic solvents. Steel-lined PTFE pipes and accessories that can operate stably under high temperature (within 150°C) extreme negative pressure conditions for a long time solve the shortcomings of steel-lined PTFE pipes and accessories that cannot withstand negative pressure in the past. They have been widely used in many high-temperature and high-negative pressure systems such as distillation. In the production process, steel-lined fluorine pipes usually need to be manufactured using a molding process. First, put the rubber tube into the pipe, then manually evenly fill the PTFE powder, and then use tools to press the PTFE powder down to make it more compact. Finally, seal the pipe, use high-pressure water to shape the PTFE powder, and finally sinter to complete the manufacturing.

[0003] Regarding the above-mentioned related technologies, although the manufacture of steel-lined fluorine pipes can be realized at present, in the actual operation process, since the PTFE powder is manually loaded, it is difficult to ensure the uniformity of the powder between the pipe and the rubber sleeve. After the loading is completed, it is manually hammered using a stick tool. Although the loading can be completed, it is easy to cause uneven and insufficient loading of the powder, which leads to different densities in different positions after the subsequent hammering of the PTFE powder, thereby affecting the sintering quality of the fluorine pipe. For this reason, we propose a molding device and process for steel-lined fluorine pipes. Summary of the invention
