Description
Technical field
The present invention relates to seamless steel pipe field.
Background technique
Along with the high speed development of national economic development and the gradual perfection of urban infrastructure, the demand of various types of steel is increasing, and seamless steel pipe is widely used in fields such as industrial production, urban construction.Seamless 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.Due under the equal condition of girth, the area of a circle is maximum, with circular pipe, can carry more fluid.In addition, ring cross-section is when bearing inside or outer radial pressure, stressed more even.But pipe also has certain narrow limitation, as being subject under the condition of plane bending, pipe is just not so good as side, rectangular tube resistance to flexure is large.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of seamless steel pipe of pressure-resistant corrosion-resisting, can overcome the deficiencies in the prior art, and pressure resistance is not yielding, and corrosion-resistant, fully meets the demand of every profession and trade to seamless steel pipe.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is:
A kind of seamless steel pipe of pressure-resistant corrosion-resisting is provided, comprise: steel pipe body, the first corrosion-inhibiting coating, the second corrosion-inhibiting coating and outer steel plate, the inwall of described steel pipe body scribbles the first corrosion-inhibiting coating, the outer wall of described steel pipe body scribbles the second corrosion-inhibiting coating, described outer steel plate is shaped as equilateral triangle on steel pipe body cross section, three faces of outer steel plate all contact with steel pipe body, and steel pipe body is wrapped in wherein.
Further, the material of the first corrosion-inhibiting coating on the seamless steel pipe of described pressure-resistant corrosion-resisting and the second corrosion-inhibiting coating is epoxy resin.
Further, the outer wall of the outside outer steel plate surrounding of the seamless steel pipe of described pressure-resistant corrosion-resisting is provided with zinc coat.
Further, the thickness of the first described corrosion-inhibiting coating and the second corrosion-inhibiting coating is 1mm ~ 3mm.
The invention has the beneficial effects as follows:
The seamless steel pipe that a kind of pressure-resistant corrosion-resisting is provided, comprising: steel pipe body, the first corrosion-inhibiting coating, the second corrosion-inhibiting coating and outer steel plate, and the inwall of steel pipe body scribbles the first corrosion-inhibiting coating, and the outer wall of steel pipe body scribbles the second corrosion-inhibiting coating.The first corrosion-inhibiting coating and the second corrosion-inhibiting coating have effectively increased the antiseptic power of steel pipe.Described outer steel plate is shaped as equilateral triangle on steel pipe body cross section, and three faces of outer steel plate all contact with steel pipe body, and steel pipe body is wrapped in wherein.Equilateral triangle is stable structure, and steel pipe body is wrapped in the anti-pressure ability that wherein can strengthen steel pipe, makes it not easy-rupturing, not yielding, increases the service life of steel pipe.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, steel pipe body, the 2, first corrosion-inhibiting coating, the 3, second corrosion-inhibiting coating, 4, outer steel plate.
