Abstract
The invention discloses a steel pipe for a guardrail. The steel pipe comprises a steel pipe body, a first impact-resisting layer, a castor oil modified epoxy polyurethane anti-corrosion coating layer, a second impact-resisting layer and a high-temperature-resisting epoxy modified organosilicone polyurethane anti-corrosion coating; the first impact-resisting layer and the castor oil modified epoxy polyurethane anti-corrosion coating layer are sequentially arranged on the outer surface of the steel pipe body from inside to outside, and the second impact-resisting layer and the high-temperature-resisting epoxy modified organosilicone polyurethane anti-corrosion coating are sequentially arranged on the inner surface of the steel pipe body from outside to inside; and through the above manner, the steel pipe is good in impact-resisting performance and corrosion-resisting performance, and the service life is effectively prolonged.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of steel pipe for guardrail.
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 anti-collision performance of the steel pipe being currently used for guardrail is poor, and decay resistance is the best, and service life is short.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of steel pipe for guardrail, and anti-collision performance is good, and decay resistance is good, effectively extends service life.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of steel pipe for guardrail, including: steel pipe body, first impact resistance layer, castor oil modified epoxy polyurethane anticorrosive coating layer, second impact resistance layer and fire resistant epoxy modified organic silicon polyurethane anticorrosive coating, the appearance of described steel pipe body is disposed with the first described impact resistance layer and described castor oil modified epoxy polyurethane anticorrosive coating layer outward from interior, the interior table of described steel pipe body is disposed with the second described impact resistance layer and fire resistant epoxy modified organic silicon polyurethane anticorrosive coating inside from outward.
In a preferred embodiment of the present invention, the first described impact resistance layer is TC4 fiber reinforcement aluminium composite material layer.
In a preferred embodiment of the present invention, the thickness of described castor oil modified epoxy polyurethane anticorrosive coating layer is 0.5 ~ 1mm.
In a preferred embodiment of the present invention, the thickness of described fire resistant epoxy modified organic silicon polyurethane anticorrosive coating is 0.8 ~ 1.5mm.
The invention has the beneficial effects as follows: anti-collision performance of the present invention is good, and decay resistance is good, effectively extend service life.
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 guardrail；
In accompanying drawing, the labelling of each parts is as follows: 1, steel pipe body, the 2, first impact resistance layer, and 3, castor oil modified epoxy polyurethane anticorrosive coating layer, the 4, second impact resistance layer, 5, fire resistant epoxy modified organic silicon polyurethane anticorrosive coating 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 guardrail, including: steel pipe body the 1, first impact resistance layer 2, castor oil modified epoxy polyurethane anticorrosive coating layer the 3, second impact resistance layer 4 and fire resistant epoxy modified organic silicon polyurethane anticorrosive coating layer 5, the appearance of described steel pipe body 1 is disposed with the first described impact resistance layer 2 and described castor oil modified epoxy polyurethane anticorrosive coating layer 3 outward from interior, and the interior table of described steel pipe body 1 is disposed with the second described impact resistance layer 4 and fire resistant epoxy modified organic silicon polyurethane anticorrosive coating layer 5 inside from outward.
In the present invention, the first described impact resistance layer 2 is TC4 fiber reinforcement aluminium composite material layer.
In the present invention, the thickness of described castor oil modified epoxy polyurethane anticorrosive coating layer 3 is 0.5 ~ 1mm.
In the present invention, the thickness of described fire resistant epoxy modified organic silicon polyurethane anticorrosive coating layer 5 is 0.8 ~ 1.5mm.
The present invention provides the benefit that for the steel pipe of guardrail: anti-collision performance of the present invention is good, and decay resistance is good, effectively extends service life.
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.
