Abstract
The invention discloses a kind of combined precision steel pipes, it include: steel pipe body, the first resistance to compression layer, microporous calcium silicate layer, the second resistance to compression layer, aluminium foil reflecting layer and corrosion-resistant coating, the inner surface of the steel pipe body is disposed with the second resistance to compression layer, the aluminium foil reflecting layer and the corrosion-resistant coating from interior from the first resistance to compression layer and the microporous calcium silicate layer, the outer surface of the steel pipe body is disposed with inside outside outward.By the above-mentioned means, the advantages of present invention is hardly damaged with intensity height, and construction and maintenance are easy, long service life.
Description
Technical field
The present invention relates to steel pipe fields, more particularly to a kind of combined precision steel pipe.
Background technique
Precision tube is a kind of tube material high-accuracy by one kind after cold-drawn or hot rolling treatment.Due to precision tube
Inside and outside wall non-oxidation layer bears indeformable high-pressure non-leakage, high-precision, best bright finish, clod wash, flaring, flattens free from flaw etc. to have
Point, so the product for being mainly used to produce pneumatically or hydraulically element can be seamless pipe, also there is welded pipe such as cylinder or oil cylinder.
The chemical component of precision tube has carbon C, silicon Si, manganese Mn, sulphur S, phosphorus P, chromium Cr.
However, precision tube intensity used at present is not high, easy to damage, construction and maintenance are not easy, and service life is short.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of combined precision steel pipes, have intensity high, are hardly damaged, apply
The advantages of work maintenance is easy, long service life.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of combined precision steel pipe is provided, is wrapped
It includes: steel pipe body, the first resistance to compression layer, microporous calcium silicate layer, the second resistance to compression layer, aluminium foil reflecting layer and corrosion-resistant coating, the steel
The inner surface of tube body from being disposed with the first resistance to compression layer and the microporous calcium silicate layer, the steel inside outside
The outer surface of tube body is disposed with the second resistance to compression layer, the aluminium foil reflecting layer and the anti-corrosion from interior outward
Lose layer.
In a preferred embodiment of the present invention, the first resistance to compression layer is the cementing paste filling material layer of iron milltailings.
In a preferred embodiment of the present invention, the second resistance to compression layer is plant fiber foam material layer.
In a preferred embodiment of the present invention, the thickness of the second resistance to compression layer is greater than the first resistance to compression layer
Thickness.
The beneficial effects of the present invention are: the present invention has intensity high, it is hardly damaged, construction and maintenance are easy, long service life
The advantages of.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for

It encloses.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of combined precision steel pipe, comprising: steel pipe body 1, the first resistance to compression layer 2, microporous calcium silicate layer 3, the second resistance to compression layer
4, aluminium foil reflecting layer 5 and corrosion-resistant coating 6, the inner surface of the steel pipe body 1 from being disposed with described first inside outside
Resistance to compression layer 2 and the microporous calcium silicate layer 3, the outer surface of the steel pipe body 1 from it is interior be disposed with outward it is described
Second resistance to compression layer 4, the aluminium foil reflecting layer 5 and the corrosion-resistant coating 6.
In the present invention, the first resistance to compression layer 2 is the cementing paste filling material layer of iron milltailings.
In the present invention, the second resistance to compression layer 4 is plant fiber foam material layer.
In the present invention, the thickness of the second resistance to compression layer 4 is greater than the thickness of the first resistance to compression layer 2.
The beneficial effect of combined precision steel pipe of the present invention is: the present invention has intensity high, is hardly damaged, construction and maintenance letter
Just, the advantages of long service life.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
