Abstract
The utility model relates to a fluorine-lined steel pipe which comprises a pipe body (1), wherein a polytetrafluoroethylene coating (2) is lined on the inner wall of the pipe body. By adopting the structure, novel material polytetrafluoroethylene is lined on the surface where the steel pipe is contacted with media, and the polytetrafluoroethylene is totally invariable in media of weak acid, strong acid, weak base, strong base and organic solvent, so that the fluorine-lined steel pipe has excellent decay resistance and is prolonged in service life. The using temperature range of polytetrafluoroethylene is -268 DEG C to 232 DEG C. Therefore, the using range of the steel pipe is increased.
Description
Technical field
The utility model relates to a kind of lining fluorine steel pipe.
Background technique
Pipeline is the device of the fluid that is used for conveying gas, liquid or band solid particle that is connected into pipe, pipe coupling and valve etc.Pipeline mainly is used in feedwater, draining, heat supply, gives gas, grows in distances oil and natural gas, agricultural irrigation, hydraulic engineering and the various commercial plant.Develop by leaps and bounds along with industrialized, existing pipeline can not satisfy the requirement of special operation condition, and the use occasion of heavy corrosion property property medium such as sulfuric acid, phosphoric acid, highly basic, chlorine etc. is particularly arranged.
Summary of the invention
The purpose of the utility model is exactly the problem for the steel pipe corrosion-resistant.
The technological scheme that the utility model adopts is: a kind of lining fluorine steel pipe, comprise body, and the inwall of said body is lined with polytetrafluorethylecoatings coatings.
The beneficial effect that the utility model adopts is: after adopting this structure; The surface that this steel pipe contacts with medium is lining new material teflon all; Teflon can not change in weak acid, strong acid, weak base, highly basic, organic solvent medium fully; Have good rotproofness, prolonged steel pipe working life.Teflon serviceability temperature scope is-268 ℃ to 232 ℃.Thereby improved the using scope of this steel pipe.
Description of drawings
Fig. 1 is the utility model schematic representation.
Embodiment
As shown in Figure 1, a kind of lining fluorine steel pipe comprises body 1, and the inwall of said body is lined with polytetrafluorethylecoatings coatings 2.After adopting this structure; The surface that this steel pipe contacts with medium is lining new material teflon all; Teflon can not change in weak acid, strong acid, weak base, highly basic, organic solvent medium fully, has good rotproofness, has prolonged steel pipe working life.Teflon serviceability temperature scope-268 is ℃ to 232 ℃.Thereby improved the using scope of this steel pipe.
