Abstract
The utility model relates to an antistatic anticorrosion pipeline. The antistatic anticorrosion pipeline comprises a steel pipe shell, wherein a fluoroplastic graphite lining pipe is lined on the inner wall of the steel pipe shell; and the fluoroplastic graphite lining pipe is optimally a polytetrafluoroethylene graphite lining pipe, and is made from polytetrafluoroethylene resin and a certain proportion of graphite powder. The anticorrosion pipeline is suitable for conveying non-conducting combustible liquid media such as petroleum, and can prevent the accidents of combustible liquid combustion explosion caused by static electricity.
Description
Technical field
The utility model relates to a kind of anti-corrosion pipeline, relates in particular to a kind of antistatic anti-corrosion pipeline.
Background technique
Anti-corrosion pipeline has been widely used in essential industry production departments such as chemical industry, petrochemical industry, metallurgy, nuclear energy and military project and has carried corrosive liquid medium.The anti-corrosion pipeline of existing non-metallic liner scarcely has anti-static function, as runs into oil or other nonconducting liquid medium conveying, and both frictions can produce static, set off an explosion easily, have serious accident hidden danger.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of antistatic anti-corrosion pipeline, to overcome the problem that existing anti-corrosion pipeline in use can not prevent static.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of antistatic anti-corrosion pipeline comprises the steel pipe shell, lining dress fluoroplastic graphite internal lining pipe on the inwall of described steel pipe shell.Described fluoroplastic graphite internal lining pipe is preferably teflon graphite internal lining pipe, is made by polyflon and a certain proportion of powdered graphite.
The utlity model has following beneficial effect: fluoroplastic graphite internal lining pipe, teflon graphite internal lining pipe had especially not only had the antiseptic property of fluoroplastic but also had had the electric conductivity of graphite.Its lining is contained in the steel pipe shell, when running into the nonconducting liquid medium of oil or other and carry, both frictions can not produce electrostatic effect, as produce static and just can discharge to the steel pipe shell of outside charge transfer by electrically conductive graphite, thereby avoid causing because of static the generation of combustable liquid combustion explosion accident.The utility model is applicable to such as nonconducting combustable liquid medium transport such as oil.
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments.
Description of drawings
Fig. 1 is a kind of embodiment of the utility model, the overall structure schematic representation of antistatic anti-corrosion pipeline.
Drawing explanation: 1, fluoroplastic graphite internal lining pipe, 2, the steel pipe shell, 3, steel flange, 4, the internal lining pipe flange.
Embodiment
Embodiment as shown in Figure 1, a kind of antistatic anti-corrosion pipeline, comprise that steel pipe shell 2 and lining are loaded on the fluoroplastic graphite internal lining pipe 1 on the steel pipe outer casing inner wall, fluoroplastic graphite internal lining pipe 1 is made by fluoroplastics resin (preferably polytetrafluoroethylene resin) and a certain proportion of powdered graphite.The granularity of powdered graphite and can select according to the granule size of different trade mark fluoroplastics resins with the ratio that fluoroplastics resin mixes.Preferred version is: the granularity of powdered graphite is 30-100 microns, and powdered graphite mixes with fluoroplastics resin with the ratio of 10-30%.
Below be example with the polyflon, the manufacture method of this antistatic anti-corrosion pipeline is described, this manufacture method comprises:
(1), graphite is pulverized, making it become granularity is 30-100 microns graphite fine powder, and look the granule size of different trade mark polyflons, mix with polyflon and stir with the ratio of 10-30%, to reach its excellent conducting performance;
(2), with the polyflon that stirs and the mixture of graphite, place in the punching block, be pressed into blank piece material with the pressure of 200～300kg/ cm2 at press, after the demoulding, blank piece material is placed in the sintering furnace sinter molding under 380 ℃ of high temperature;
(3), cooling back takes out, and the blank piece truck of sinter molding is whittled into thick 0.1mm, the teflon strip of wide about 30mm;
(4), with multi-lay winding integral sintered technology, strip is wound to desired thickness back and forth on mould, and tightly ties up outside it with resistant to elevated temperatures glass fiber tape, whole work-piece is put into sinter molding in the sintering furnace and is become teflon graphite internal lining pipe;
(5), teflon graphite internal lining pipe lining is contained in the steel pipe shell that adapts to it, the two ends flange namely becomes the antistatic anti-corrosion pipeline product that can not cause the static blast.
Claims (2)
1. an antistatic anti-corrosion pipeline comprises the steel pipe shell, it is characterized in that: lining dress fluoroplastic graphite internal lining pipe on the inwall of described steel pipe shell.
2. antistatic anti-corrosion pipeline according to claim 1, it is characterized in that: described fluoroplastic graphite internal lining pipe is teflon graphite internal lining pipe.
