Abstract
The invention discloses a steel lining polytef composite pipe which comprises a pipe body. A plastic pipe is arranged on the inner periphery of the pipe body and fixedly arranged in the pipe body, and a passage is arranged circumferentially in the pipe wall of the plastic pipe and filled with liquid. The passage is arranged circumferentially in the pipe wall of the plastic pipe and filled with the liquid, so that when the steel lining polytef composite pipe is in use, the liquid plays a role in supporting the plastic pipe, the plastic pipe can be protected well, and remarkable effect on aspects like pressure resistance is realized. In addition, the liquid accounts for two thirds of size of the passage, so that strength of the steel lining polytef composite pipe is further improved, and high pressure resistance of the steel lining polytef composite pipe is effectively improved.
Description
Technical field
The present invention relates to a kind of tubing, particularly a kind of Novel steel lining teflon composite pipe fitting.
Background technique
Steel lining composite pipe, is using normal carbon steel pipe as matrix, and the thermoplastic pipes that liner chemical stability is good, through cold drawn compound or rotationally molding.The mechanical property of its existing steel pipe, has again the corrosion-resistant of plastic tube, slow fouling, and the feature of difficult growth microorganism, is the ideal conduit of transport acid, alkali, salt, the media such as gas that are corrosive.Be widely used in medium transport and the environment-friendly disposal system of the industries such as chemical industry, electric power, metallurgy, food.Along with industrialized fast development, steel lining composite pipe has more and more stricter requirement for the aspect such as high pressure resistant, corrosion-resistant, high temperature resistant.
Summary of the invention
The object of the invention is in order to overcome above deficiency, a kind of steel lining polyfluortetraethylecomposite composite pipe part is provided, promote the performance such as high pressure resistant, corrosion-resistant, high temperature resistant, ageing-resistant of tubing, improve its using effect.
Object of the present invention realizes like this:
A kind of steel lining polyfluortetraethylecomposite composite pipe of the present invention part, comprises body, in described body, week is provided with plastic tube, and described plastic tube is fixedly installed in described body, wherein, in described plastic tube wall, along being circumferentially with passage, in described passage, is filled with liquid.
Above-mentioned steel lining polyfluortetraethylecomposite composite pipe part, wherein, described channel width is 3mm.
Above-mentioned steel lining polyfluortetraethylecomposite composite pipe part, wherein, described liquid accounts for 2/3 of described channel volume.
Compared with prior art, the present invention has the following advantages:
Due in described plastic tube wall along being circumferentially with passage, in described passage, be filled with liquid, when use, liquid plays supporting effect to plastic tube, can play good protection plastic tube, and there is to remarkable effect the aspect such as withstand voltage.And because described liquid accounts for 2/3 of described channel volume., further improve the intensity of tubing, effectively improve its high voltage performance.
Brief description of the drawings
Fig. 1 is plan view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of steel lining polyfluortetraethylecomposite composite pipe of the present invention part, comprise body 1, described interior week of body 1 is provided with plastic tube 2, described plastic tube 2 is fixedly installed in described body 1, in described plastic tube 2 tube walls, along being circumferentially with passage 3, in described passage 3, is filled with liquid, liquid can be water, also can be other and have the liquid of antisepsis.Passage 3 is arranged on described plastic tube 2 tube wall position of center line places, and described channel width is 3mm, and described liquid accounts for 2/3 of described channel volume.
The performance data of the prepared withstand voltage polytetrafluoroethyltubing tubing of table 1 the present invention
| Test event | Unit | Index |
| The highest malleation of bearing | Mpa | 1.7 |
| The highest negative pressure of bearing | Kpa | 110 |
| Medium operating temperature | ℃ | -110-253 |
Above embodiment is only used to further illustrate the present invention; can not be interpreted as limiting the scope of the invention, some nonessential improvement that those skilled in the art's foregoing according to the present invention is made and adjustment all belong to protection scope of the present invention.
Claims (2)
