Abstract
The invention discloses a steel pipe for a drinking water pipeline. The steep pipe comprises a steel pipe body, a first corrosion resistant coating, an anti-freezing protection layer, a second corrosion resistant coating, a first anti-bacterial layer, and a second anti-bacterial layer. An outer surface of the steel pipe body is provided with the first corrosion resistant coating and the anti-freezing protection layer in order from inside to outside, while an inner surface of the steel pipe body is provided with the second corrosion resistant coating, the first anti-bacterial layer and the second anti-bacterial layer in order from outside to inside. In such a way, the steel pipe for the drinking water pipeline has an anti-bacterial function and excellent corrosion resistance, and the outer wall thereof also has a freeze protection function.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of steel pipe for drinking water pipeline.
Background technology
Steel pipe is the strip steel of a kind of hollow, a large amount of pipelines being used as conveyance fluid, such as oil, natural gas, water, coal gas, steam etc., it addition, when doing curved, torsional strength and being identical, lighter in weight, so being also widely used in manufacture machine components and engineering structure.
Steel pipe can be divided into two big classes by production method: seamless steel pipe and seamed steel pipe, seamed steel pipe is referred to as steel pipes with straight.Seamless steel pipe can be divided into by production method: hot seamless tube, drawn tube, precision tube, hot-expanding pipe, cold spinning pipe and extruded tube etc..Seamless steel pipe Fine Steel Casting iron or steel alloy are made, have hot rolling, cold rolling (pulling out) point.Seamless steel pipe can be used for liquid air-pressure duct and the gas pipeline etc. of various industry.Welded pipe line can be used for aqueduct, gas piping, caliduct, electrical equipment pipeline etc..
But, the inwall of the steel pipe being currently used for drinking water pipeline does not have antibacterial functions, and Corrosion Protection is the best, and does not the most have anti-freezing function on outer wall.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of steel pipe for drinking water pipeline, and inwall has antibacterial functions, and Corrosion Protection is good, and also has anti-freezing function on outer wall.
For solving above-mentioned technical problem; the technical scheme that the present invention uses is: provide a kind of steel pipe for drinking water pipeline; including: steel pipe body, the first corrosion-inhibiting coating, anti-freezing protective layer, the second corrosion-inhibiting coating, the first antibiotic layer and the second antibiotic layer; the appearance of described steel pipe body is disposed with the first described corrosion-inhibiting coating and described anti-freezing protective layer outward from interior, and the interior table of described steel pipe body is disposed with the second described corrosion-inhibiting coating, the first described antibiotic layer and the second described antibiotic layer inside from outward.
In a preferred embodiment of the present invention, the first described corrosion-inhibiting coating is modification acrylate anticorrosive metal paint layer.
In a preferred embodiment of the present invention, the thickness of described anti-freezing protective layer is 1 ~ 2mm.
In a preferred embodiment of the present invention, the first described antibiotic layer is nano silicon Ag-carried antibacterial dope layer.
The invention has the beneficial effects as follows: inwall of the present invention has antibacterial functions, Corrosion Protection is good, and also has anti-freezing function on outer wall.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the present invention structural representation for steel pipe one preferred embodiment of drinking water pipeline；
In accompanying drawing, the labelling of each parts is as follows: 1, steel pipe body, the 2, first corrosion-inhibiting coating, and 3, anti-freezing protective layer, the 4, second corrosion-inhibiting coating, the 5, first antibiotic layer, the 6, second antibiotic layer.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of steel pipe for drinking water pipeline; including: steel pipe body the 1, first corrosion-inhibiting coating 2, anti-freezing protective layer the 3, second corrosion-inhibiting coating the 4, first antibiotic layer 5 and the second antibiotic layer 6; the appearance of described steel pipe body 1 is disposed with the first described corrosion-inhibiting coating 2 and described anti-freezing protective layer 3 outward from interior, and the interior table of described steel pipe body 1 is disposed with the second described corrosion-inhibiting coating 4, the first described antibiotic layer 5 and the second described antibiotic layer 6 inside from outward.
In the present invention, the first described corrosion-inhibiting coating 2 is modification acrylate anticorrosive metal paint layer.
In the present invention, the thickness of described anti-freezing protective layer 3 is 1 ~ 2mm.
In the present invention, the first described antibiotic layer 5 is nano silicon Ag-carried antibacterial dope layer.
The present invention provides the benefit that for the steel pipe of drinking water pipeline: inwall of the present invention has antibacterial functions, and Corrosion Protection is good, and also has anti-freezing function on outer wall.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in the scope of patent protection of the present invention.
