Description
Technical field
The present invention relates to anti-corrosion pipe technical field, especially a kind of polyfluortetraethylecomposite composite pipe.
Background technology
Polytetrafluoroethylene (PTFE)（Polytetrafluoroethylene, it is abbreviated as PTFE）, commonly referred to as " non-sticking lining " or
" material easy to clean.This material has antiacid alkali resistant, resists the characteristics of various organic solvents, is practically insoluble in all solvents.Institute
Using anticorrosive coat that can be polytetrafluoroethylene spray in the outer surface of metallic conduit as metallic conduit, due to polytetrafluoroethylene (PTFE) material
Very hard, the adhesive force on metallic conduit is very small, and the polytetrafluoroethylene floor after spraying is easy to come off, so as to lead to not
To the anti-corrosion to metallic conduit.
The content of the invention
The technical problem to be solved in the present invention is：Polytetrafluoroethylene (PTFE) material is hard in order to solve, the attachment on metallic conduit
The problem of power is very small, and the polytetrafluoroethylene floor after spraying is easy to come off, the invention provides a kind of polytetrafluoroethylene (PTFE) is compound
Pipe, by being provided with groove on the lateral wall of polytetrafluoroethylplastic plastic pipe, rubber ring is caught in groove, prevents rubber ring poly-
Ptfe plastic pipe slides, and is contacted by rubber ring with metal tube, because the elasticity of rubber ring is fine, in the case of crushing
It can be good at being attached on metal tube, so as to being fixed on the inside of metal tube steadily by polytetrafluoroethylplastic plastic pipe, so as to have
Effect prevents the slippage of polyfluortetraethylene pipe, ensure that antiseptic effect.
The technical solution adopted for the present invention to solve the technical problems is：A kind of polyfluortetraethylecomposite composite pipe, including metal
Manage and be arranged on the polytetrafluoroethylplastic plastic pipe in metal tube, in addition to several annular rubber rings, the polytetrafluoroethylene (PTFE)
The lateral wall of plastic tube is circumferentially with the annular groove matched with rubber ring, when rubber ring is fixed in groove, rubber ring
Outer surface be higher than polytetrafluoroethylplastic plastic pipe outer surface so that the outer surface of rubber ring and the inner surface of metal tube closely connect
Touch.
In order to increase the adhesive force of metal tube and rubber ring, the outer surface of the rubber ring is higher by polytetrafluoroethylplastic plastic pipe
Outer surface 10mm-15mm.
In order to ensure the antiseptic effect on the outside of metal tube, the lateral surface of the metal tube is provided with the preserving timber bed of material.
Specifically, the anti-corrosion material paints for poly- corrosion resistance.
Specifically, the rubber ring is provided with anti-skid bulge, can further increase adhesive force.
The beneficial effects of the invention are as follows：The invention provides a kind of polyfluortetraethylecomposite composite pipe, by polytetrafluoroethylene (PTFE)
The lateral wall of plastic tube is provided with groove, and rubber ring is caught in groove, can effectively prevent rubber ring in polytetrafluoroethylene (PTFE)
Plastic tube slides, fixed with rubber ring so as to which polytetrafluoroethylene (PTFE) be moulded, and is contacted by rubber ring outer surface with metal tube, by
It is fine in the elasticity of rubber ring, it can be good at being attached on metal tube in the case of crushing, so as to which polytetrafluoroethylene (PTFE) be moulded
Expects pipe being fixed on the inside of metal tube steadily, effectively prevent the slippage of polyfluortetraethylene pipe, and serve on the inside of metal tube
Antiseptic effect, and polytetrafluoroethylplastic plastic pipe is fixedly connected with metal tube by rubber ring, polytetrafluoroethylplastic plastic pipe
There can be gap between metal tube, the effect of heat-insulation and heat-preservation can be played.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural representation of polyfluortetraethylecomposite composite pipe of the present invention.
Embodiment
