Description

Galvanized welded pipe
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of welded tube, especially a kind of galvanized welded pipe.
Background technique
For the corrosion resistance for improving steel pipe, general steel pipe is carried out zinc-plated.Old house largely be all zinc-plated weldering Pipe, that iron pipe of coal gas, heating is also galvanized welded pipe, and galvanized welded pipe is as water pipe, after several years, manages interior generate largely Rust deposite, the yellow water of outflow not only pollute sanitary ware, but also are mingled with the bacterium that rough inner wall is bred, and corrosion causes heavy metal in water Too high levels seriously endanger the health of human body.
Coating steel pipe is divided to hot galvanizing and two kinds of electrogalvanizing.Hot galvanized steel pipe be widely used in building, machinery, coal mine, chemical industry, Electric power, rail truck, auto industry, highway, bridge, container, sports equipment, agricultural machinery, petroleum machinery, mine locating machinery etc. Process industry.Galvanized welded pipe: there is the welded still pipe of hot-dip or electro-galvanized layer on surface.The zinc-plated anticorrosive energy for increasing steel pipe Power prolongs the service life.Galvanized welded pipe has many uses, except the line pipe for making the general low-pressure fluid such as water delivery, coal gas, oil Outside, oil well pipe, the petroleum pipeline of petroleum industry especially marine oil field are also served as, the oil heater of chemical industry coker, condensation are cold But device, coal evaporate washing oil exchanger pipe and trestle tubular pole, the support rack pipe in mine tunnel etc..But common galvanized welded pipe It is only zinc-plated in steel pipe, therefore its intensity is inadequate, and the wall thickness of general galvanized welded pipe is all thicker, heavier-weight.
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes that a kind of structural strength is high and matter Measure lighter galvanized welded pipe.
The purpose of this utility model can be realized by the following technical scheme: galvanized welded pipe, including internal layer and outer layer, institute The lateral wall for the outer layer stated uniformly is coated with zinc coat, which is characterized in that carbon is equipped between the internal layer and the outer layer Fibrous layer, the inner sidewall of the internal layer are coated with one layer of anti-corrosion layer, the lateral wall of the internal layer be uniformly provided with it is parallel its The inner sidewall of the positioning convex body of axis setting, the outer layer has the positioning groove to match with the positioning convex body and institute The positioning convex body stated is in corresponding positioning groove.
Due to being equipped with carbon fiber layer between internal layer and outer layer, the intensity of this galvanized welded pipe is increased, due to the inside of internal layer Wall is coated with one layer of anti-corrosion layer, improves the corrosion resistance of internal layer, since the positioning convex body on the lateral wall of internal layer is embedded in fixed In the groove of position, the intensity of this galvanized welded pipe is enhanced, since the lateral wall of outer layer is uniformly coated with zinc coat, is had preferable resistance to Corrosive effect.
In above-mentioned galvanized welded pipe, the lateral wall of the outer layer is equipped with carburized layer, and the zinc coat is located at described Carburized layer lateral wall.The lateral wall of outer layer is equipped with carburized layer, improves the intensity of outer layer, has preferable protection effect.
In above-mentioned galvanized welded pipe, the carburized layer with a thickness of 1.2mm-2.4mm.
In above-mentioned galvanized welded pipe, the lateral wall of the positioning convex body be arc-shaped and the positioning groove it is interior Side wall is arc-shaped, and the lateral wall of the positioning convex body sticks on the inner sidewall of the positioning groove.Arc-shaped determines Position convex body sticks in corresponding positioning groove, has preferable locating effect and avoids stress concentration, has and preferably connect Connect effect.
In above-mentioned galvanized welded pipe, the quantity of the positioning convex body be 6-20 and with the axis of the internal layer be Center is uniformly arranged.
In above-mentioned galvanized welded pipe, the anti-corrosion layer be carburized layer two and the carburized layer two with a thickness of 1.2mm-2.4mm。
In above-mentioned galvanized welded pipe, the carbon fiber layer with a thickness of 0.2mm to 0.6mm.The thickness of carbon fiber layer For 0.2mm to 0.6mm, make this galvanized welded pipe intensity with higher.
Compared with prior art, this galvanized welded pipe has the advantage that
1, due to being equipped with carbon fiber layer between internal layer and outer layer, the intensity of this galvanized welded pipe is increased, due in internal layer Side wall is coated with one layer of anti-corrosion layer, improves the corrosion resistance of internal layer;
2, since the positioning convex body on the lateral wall of internal layer is in positioning groove, the intensity of this galvanized welded pipe is enhanced, Since the lateral wall of outer layer is uniformly coated with zinc coat, there is preferable anticorrosion effect;
3, the lateral wall of outer layer is equipped with carburized layer, improves the intensity of outer layer, has preferable protection effect;
4, carbon fiber layer with a thickness of 0.2mm to 0.6mm, make this galvanized welded pipe intensity with higher.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of this galvanized welded pipe.
In figure, 1, internal layer;2, outer layer;3, carbon fiber layer;4, zinc coat;5, anti-corrosion layer;6, positioning convex body;7, it positions recessed Slot;8, carburized layer.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these examples.
As shown in Figure 1, galvanized welded pipe, including internal layer 1 and outer layer 2, the lateral wall of outer layer 2 are uniformly coated with zinc coat 4, Between internal layer 1 and outer layer 2 be equipped with carbon fiber layer 3, carbon fiber layer 3 with a thickness of 0.2mm to 0.6mm.
