Description

Technical Field

[0001] The utility model relates to the technical field of steel-lined pipes, in particular to steel-lined polytetrafluoroethylene pipes. Background Art

[0002] Chemical product transportation pipelines generally use steel-lined PTFE pipes to transport chemical liquids. Steel-lined PTFE pipes are made of high-quality plunger-extruded pipes. A special processing technology is used to tightly combine the steel pipe and the plastic pipe. Steel-lined PTFE pipes have excellent temperature resistance and corrosion resistance. They are ideal for conveying highly corrosive media such as nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine, aqua regia, mixed acid, bromide and other organic solvents.

[0003] According to a Chinese patent with the publication number "CN221424136U", a steel-lined polytetrafluoroethylene pipe is disclosed, which includes a steel liner, a polytetrafluoroethylene pipe body is arranged inside the steel liner, a buffer pad is arranged inside the polytetrafluoroethylene pipe body, a steel pipe is arranged inside the buffer pad, an inner layer pipe is inserted into the steel pipe, the inner layer pipe includes an antistatic layer, and a metal layer is arranged inside the antistatic layer. The annular drainage column of the utility model has a deceleration effect, which can reduce the liquid flow rate and reduce the noise generation. The sound insulation layer further reduces the noise, ensuring the maximum noise reduction effect. When connecting two pipe bodies, the insert pipe cooperates with the slot, which can be positioned when the two pipes are connected, and the insert pipe and the slot cooperate with several rubber rings to form a double sealing structure, which improves the sealing of the connection between the two pipe bodies. The corrosion-resistant layer completely covers the inner surface of the polytetrafluoroethylene plate, further improving the corrosion resistance of the inner pipe, and increasing the service life of the pipe. When in use, the pipe is exposed to the outside and is easily damaged by external impact, so it is necessary to protect the pipe. Therefore, a steel-lined polytetrafluoroethylene pipe is proposed to solve the above-mentioned problems. Utility Model Content
