Abstract
The invention discloses a water conservancy seamless steel tube which comprises a steel tube body, an antifreeze protecting layer, anti-shock pressure resistance layer, an anti-incrustation and antifouling layer, a first weather-proof anti-corrosion protective layer and a second weather-proof anti-corrosion protective layer. The inner wall of the steel tube body is sequentially provided with the anti-shock pressure resistance layer and the anti-incrustation and antifouling layer, and the outer wall of the steel tube body is sequentially provided with the antifreeze protecting layer, the first weather-proof anti-corrosion protective layer and the second weather-proof anti-corrosion protective layer. Through above mode, the water conservancy seamless steel tube is good in anti-shock pressure resistance performance, incrustation can not be generated on the inner wall of the steel tube, a water source can not be polluted easily, the water conservancy seamless steel tube is suitable for being used in winter with low temperatures, the weather-proof anti-corrosion performance is good, and the service life of the steel tube is effectively prolonged.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of water conservancy seamless steel pipe.
Background technique
Seamless steel pipe is that one has hollow section, periphery does not have jointed rectangular steel.Steel pipe has hollow section, and a large amount of pipelines as carrying fluid, as the pipeline of transfer oil, rock gas, coal gas, water and some solid material etc.Steel pipe is compared with the solid steel such as round steel, in the time that bending resistance twisting strength is identical, weight is lighter, is a kind of Economic Section steel, be widely used in manufacturing structure part and mechanical parts, as steel scaffold of using in oil drill rocker, truck drive shaft, bicycle frame and construction etc.Manufacture ring-shaped work pieces with steel pipe, can improve stock utilization, simplify manufacturing process, save material and machining period, as rolling bearing lasso, very heavy top cover etc., extensively manufacture with steel pipe at present.Steel pipe or the indispensable material of various conventional weapon, gun barrel, gun barrel etc. is all wanted steel pipe manufacture.Steel pipe can be divided into pipe and steel tubing in different shapes by the difference of cross-section area shape.
But, now water conservancy is poor with seamless steel pipe shock resistance withstand voltage properties, and steel pipe inner wall of long duration easily has incrustation scale polluted source, easily freezes steel pipe is frozen in the winter that temperature is lower, weather-proof Corrosion Protection is also poor, and these situations have all shortened the working life of steel pipe.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of water conservancy seamless steel pipe, shock resistance good pressure-resistant performance, steel pipe inner wall of long duration is also difficult for having the incrustation scale can polluted source, is applicable to the winter that temperature is lower, weather-proof Corrosion Protection is good, has effectively extended the working life of steel pipe.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of water conservancy seamless steel pipe is provided, comprise: steel pipe body, anti-frost protection layer, shock resistance Withstand voltage layer, water resistant dirt stain-proofing layer, the first weather-proof anti-corrosion protection layer and the second weather-proof anti-corrosion protection layer, on the inwall of described steel pipe body, be disposed with described shock resistance Withstand voltage layer and described water resistant dirt stain-proofing layer, on the outer wall of described steel pipe body, be disposed with described anti-frost protection layer, the first described weather-proof anti-corrosion protection layer and the second described weather-proof anti-corrosion protection layer.
In a preferred embodiment of the present invention, described water resistant dirt stain-proofing layer is nanometer titanium dioxide coating.
In a preferred embodiment of the present invention, the first described weather-proof anti-corrosion protection layer is acrylic resin modified anticorrosive coating.
In a preferred embodiment of the present invention, the second described weather-proof anti-corrosion protection layer is Weather-resistant epoxy polyurethane anticorrosive paint.
The invention has the beneficial effects as follows: shock resistance good pressure-resistant performance of the present invention, steel pipe inner wall of long duration is also difficult for having the incrustation scale can polluted source, is applicable to the winter that temperature is lower, and weather-proof Corrosion Protection is good, has effectively extended the working life of steel pipe.
Embodiment
To the technological scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of water conservancy seamless steel pipe; comprise: steel pipe body, anti-frost protection layer, shock resistance Withstand voltage layer, water resistant dirt stain-proofing layer, the first weather-proof anti-corrosion protection layer and the second weather-proof anti-corrosion protection layer; on the inwall of described steel pipe body, be disposed with described shock resistance Withstand voltage layer and described water resistant dirt stain-proofing layer, the anti-frost protection layer described in being disposed with on the outer wall of described steel pipe body, the first described weather-proof anti-corrosion protection layer and the second described weather-proof anti-corrosion protection layer.
Preferably, described water resistant dirt stain-proofing layer is nanometer titanium dioxide coating.
Preferably, the first described weather-proof anti-corrosion protection layer is acrylic resin modified anticorrosive coating.
Preferably, the second described weather-proof anti-corrosion protection layer is Weather-resistant epoxy polyurethane anticorrosive paint.
Water conservancy of the present invention with the beneficial effect of seamless steel pipe is: shock resistance good pressure-resistant performance of the present invention, steel pipe inner wall of long duration is also difficult for having the incrustation scale can polluted source, be applicable to the winter that temperature is lower, weather-proof Corrosion Protection is good, has effectively extended the working life of steel pipe.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
