Abstract
The utility model relates to a polytetrafluoroethylene and steel wire five-layered compact lining composite steel tube which is mainly used for solving the problems of low strength, poor stability and short service life of the existing composite tube. The composite tube comprises a tube body, wherein the two ends of the tube body are respectively provided with a flange, the inner part of the tube is provided with a lining layer, and the lining layer sequentially comprises a first polytetrafluoroethylene layer, a steel wire layer and a second polytetrafluoroethylene layer which are matched with one another from the inside to the outside. The lining layer of the composite tube adopts a mode that the winding steel wire is led into the polytetrafluoroethylene layers, so that the strength of the tube is effectively improved; and the lining layer is effectively controlled to freely stretch, so the cold flow influence is eliminated, the rigidity of the lining tube is increased, the strength of the lining layer is improved, and the negative pressure prevention capability can be effectively improved, so that the service life of the tube can be prolonged.
Description
Technical field
The utility model relates to a kind of steel pipe, refers in particular to a kind of teflon and adds five layers of compound tight lined steel pipe of steel wire.
Background technique
Composite pipe is made up of steel pipe and inboard backing layer, and it is teflon that backing layer comprises innermost layer, and teflon has high chemical stability, the deep-etching chemical substance commonly used that its ability is nearly all; Also having resistant to elevated temperatures characteristics simultaneously, is desirable corrosion material, but in use, because Influence of Temperature; Backing layer very easily damages, and when temperature raise, backing layer produced bubbling or blocked the medium circulation because of profound; When temperature descended, backing layer shrank excessive, can the flange rotation angle position drawing crack of flange two ends be leaked; Thereby had a strong impact on its extensive influence, and when MEDIA FLOW during through steel pipe and since backing layer intensity a little less than; Bear the negative pressure ability, backing layer is damaged easily, thereby causes reduce its life-span in life-span.
Summary of the invention
In order to overcome deficiency and the defective in the background technique, the utility model provides a kind of teflon to add five layers of compound tight lined steel pipe of steel wire, solve existing composite pipe exist low, the stable difference of intensity and working life short problem.
The technological scheme of the utility model is: a kind of teflon adds five layers of compound tight lined steel pipe of steel wire; Comprise body; Described body inboard is provided with backing layer, and said backing layer is followed successively by first polytetrafluoroethylene floor, steel wire floor and second polytetrafluoroethylene floor that fits from the inside to the outside.
Said perfluoroethylene-propylene layer, glass of outwards being fitted successively by second polytetrafluoroethylene floor knitted layer and high-temperature resin glue-line, and described high-temperature resin glue-line and inboard wall of tube body fit.
Said steel wire floor is a stainless steel material.
Said body is a steel pipe, and the two ends of said steel pipe are provided with flange.
Compared with prior art, the utlity model has following beneficial effect: because the backing layer of this composite pipe adopts winding steel wire is introduced the teflon coating interior, thereby make that the intensity of this pipe fitting is effectively improved; Effectively the control backing layer freely stretches; Eliminate the influence of cold flow properties, strengthened the rigidity of internal lining pipe, improved the intensity of backing layer; Make that anti-negative pressure ability is effectively improved, thereby make and obtain its working life prolonging.
Description of drawings
Fig. 1 is the partial sectional view of the utility model.
Fig. 2 is the structural representation of backing layer in the utility model.
Among the figure, body 1, backing layer 2, the first polytetrafluoroethylene floors 21, steel wire floor 22, the second polytetrafluoroethylene floors 23, perfluoroethylene-propylene layer 24, glass are knitted layer 25, high-temperature resin glue-line 26, flange 3.
Embodiment
Be described further to the embodiment of accompanying drawing below the utility model:
Shown in figure, this teflon adds five layers of compound tight lined steel pipe of steel wire, comprises body 1; Said body 1 is a steel pipe; The two ends of said body 1 are provided with flange 3, and described body 1 inboard is provided with backing layer 2, and said backing layer 2 is followed successively by first polytetrafluoroethylene floor 21, steel wire floor 22 and second polytetrafluoroethylene floor 23 that fits from the inside to the outside; Said steel wire floor 22 is a stainless steel material, will twine the Stainless Steel Wire layer that forms through winding working procedure and be incorporated in the teflon.According to such scheme, because the backing layer of this composite pipe adopts winding steel wire is introduced the teflon coating interior, thereby make that the intensity of this pipe fitting is effectively improved; Effectively the control backing layer freely stretches; Eliminate the influence of cold flow properties, strengthened the rigidity of internal lining pipe, improved the intensity of backing layer; Make that anti-negative pressure ability is effectively improved, thereby make and obtain its working life prolonging.
In the utility model, said perfluoroethylene-propylene layer 24, glass of outwards being fitted successively by second polytetrafluoroethylene floor 23 knitted layer 25 and high-temperature resin glue-line 26, and described high-temperature resin glue-line 26 fits with body 1 inwall.This backing layer is followed successively by first polytetrafluoroethylene floor 21, steel wire floor 22 and second polytetrafluoroethylene floor 23, perfluoroethylene-propylene layer 24 from the inside to the outside, glass is knitted layer 25 and high-temperature resin glue-line 26; The backing layer that adopts above-mentioned material to form; Make it in use; Advantage with corrosion-resistant, high tenacity, good stability and long service life, practicability is high.
Embodiment should not be regarded as the restriction to model utility, but any improvement of doing based on the spirit of the utility model, all should be within the protection domain of the utility model.
