Abstract
The utility model relates to the technical field of steel pipes, in particular to a corrosion-resistant steel pipe. The corrosion-resistant steel pipe comprises a steel pipe body, wherein the outer surface of the steel pipe body is coated with an adhesive; the exterior of the adhesive is coated with an epoxy powder coating layer; the exterior of the epoxy powder coating layer is coated with a polyethylene coating layer. According to the adopted technical scheme, the corrosion-resistant steel pipe has the beneficial effects of good corrosion resistance effect, simplicity in manufacturing and low cost; epoxy coal pitch serving as a corrosion-resistant layer has the characteristics of quickness in drying, good adhesion, high flexibility, acid resistance, alkali resistance, salt resistance and water resistance; the corrosion-resistant epoxy powder coating layer has the advantages of simplicity and convenience in coating operation, no pollution, excellent impact resistance and bending resistance, high-temperature resistance and the like.
Description
Technical field
The utility model relates to technique of pipe field, especially a kind of anti-corrosive steel pipe.
Background technique
Anti-corrosive steel tube refers to that processing is processed through anticorrosion process, can effectively prevent or slow down the steel pipe that chemistry or electrochemical reaction generation corrosion phenomenon occur in transport and using process.According to China's Statistical data, annual domestic pipe corrosion direct economic loss more than 2,800 hundred million, the whole world is every year because steel pipe corrosion loss is up to 5,000 hundred million dollars at present.Anti-corrosive steel tube can prevent or slowing down corrosion effectively.
Traditional metal to comb because long buried under, especially easily rust corrosion, even cause wear, the serious problems such as obstruction.And existing corrosion protection pipeline cost of production is high, anticorrosion ability is not good, working life is short, and user cost is high.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of anti-corrosive steel pipe is provided.
For solving the problems of the technologies described above, the technological scheme that this practicality adopts is as follows:
A kind of anti-corrosive steel pipe, comprises steel pipe, and described steel pipe surface scribbles adhesive, and described adhesive scribbles one deck FBE outward, and described FBE scribbles layer of polyethylene coating outward.
Further, the size of grain of described epoxy powder is 120～150 μ m.
Further, described polyethylene layer also scribbles second layer polyethylene layer outward.
Further, it is epoxide coal bituminous that described second layer polyethylene layer also has one deck outward.
Adopt the beneficial effect of the technical solution of the utility model to be: anti-corrosive steel pipe favorable anti-corrosion effect of the present utility model, make simple, cost is low, adopt epoxide coal bituminous as corrosion-resistant coating have dry rapidly, the feature that adhesion is good, pliability is good, and the epoxide coal bituminous feature with acidproof, alkaline-resisting, salt tolerant, water-fast, salt tolerant, epoxy powder anti-corrosion coating has the advantages such as apply easy and simple to handle, pollution-free, coating impact resistance and bending resistance is good, high temperature resistant.
Brief description of the drawings
Fig. 1 is the structural representation of anti-corrosive steel pipe of the present utility model.
In figure, 1 is steel pipe, and 2 is adhesive, and 3 is FBE, and 4 is polyethylene coating, and 5 is second layer polyethylene layer, and 6 is epoxide coal bituminous.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, anti-corrosive steel pipe of the present utility model, comprises steel pipe 1, and described steel pipe 1 appearance scribbles adhesive 2, the outer one deck FBE 3 that scribbles of described adhesive 2, the outer layer of polyethylene coating 4 that scribbles of described FBE 3.The size of grain of described epoxy powder is 120～150 μ m.The outer second layer polyethylene layer 5 that also scribbles of described polyethylene layer 4.5 layers of outer one deck epoxide coal bituminous 6 in addition of described second layer polyethylene.
