Abstract
The utility model relates to a plastic lining steel pipe, relating to a steel pipe for conveying fluid, particularly for conveying corrosive fluid. The inner wall of the steel pipe is lined with a layer of anticorrosive thermosetting or thermoplastic material layer, and the plastic layer extends to the end surface of the outer flange of the steel pipe end. The utility model combines the advantages of pressure resistance and high strength of the steel pipe and wash resistance and corrosion resistance to acid and alkali of the plastic pipe, and has convenient connection and long service life, so the utility model is particularly suitable to be used as the pipelines fro conveying corrosive fluid in the industries of chemical industry, petroleum, medicine, etc.
Description
The utility model relates to a kind of conveyance fluid that is used for, especially for the pipeline of carrying corrosive fluid.
In chemical industry, oil, medicine and other fields, often to utilize various pipelines to carry various fluids.In the prior art, the most frequently used fluid-transporting tubing is steel pipe and various plastic tube.Therefore advantages such as steel pipe has the intensity height, and is withstand voltage, but the poor-performing of its acid-alkali-corrosive-resisting, when being used to carry corrosive fluid, its working life is shorter, is easy to be corroded and causes corrosive fluid to leak.Though plastic tube have anti-ly wash away, advantage such as acid-alkali-corrosive-resisting, its intensity is lower, withstand voltage properties is relatively poor, should not use separately under the pressure condition with higher.Obviously, if can obtain a kind of fluid-transporting tubing that has both length concurrently, then can expand its using scope greatly, prolong its working life.
The purpose of this utility model just is being to obtain a kind ofly to have that steel strength height, withstand voltage and plastic tube anti-ly wash away, the fluid-transporting tubing of corrosion-resistant advantage concurrently.
To achieve these goals, the utility model covers the end face that serves as a contrast corrosion resistant thermosetting property of one deck or thermoplastic plastic layer and make it to extend to adpting flange outside the steel pipe port at the inwall of steel pipe, thereby obtains a kind of line plastic-steel tube.Be described in further detail below in conjunction with the technical characteristics of specific embodiment the utility model line plastic-steel tube.
Accompanying drawing 1 is the structural representation of the utility model line plastic-steel tube.
With reference to the accompanying drawings 1, the utility model line plastic-steel tube is made of steel pipe 1 and plastic layer 2, and plastic layer 2 can be thermosetting plastics or thermoplastic, adopts suitable technology to cover lining on steel pipe 1 inwall and extend to the end face of adpting flange 3 outside the steel pipe port.
The utility model has the advantage of steel strength height, withstand voltage and plastic tube resistance to erosion, acid-alkali-corrosive-resisting concurrently, and easy to connect, long service life. Therefore, the utility model is particularly suitable for being used as the pipeline of carrying corrosive fluid in chemical industry, oil, medicine and other fields.
Claims (1)
1, a kind of conveyance fluid that is used for, especially for the steel pipe of carrying corrosive fluid, its end has adpting flange; Of the present utility modelly be characterised in that described steel pipe inwall covers and be lined with corrosion resistant thermosetting property or thermoplastic plastic layer that plastic layer extends to steel pipe port outward flange end face.
