Abstract
The invention discloses a composite precise steel pipe. The steel pipe comprises a steel pipe body, a first compression resistance layer, a micro-porous calcium silicate layer, a second compression resistance layer, an aluminum foil reflection layer and an anti-corrosion layer; the first compression resistance layer and the micro-porous calcium silicate layer are sequentially arranged on the inner surface of the steel pipe body from outside to inside, and the second compression resistance layer, the aluminum foil reflection layer and the anti-corrosion layer are sequentially arranged on the outer surface of the steel pipe body from inside to outside; and through the above manner, the steel pipe has the beneficial effects of being high in strength, not prone to being damaged, easy and convenient to construct and overhaul and long in service life.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of combined precision steel pipe.
Background technology
Precision tube is a kind of by a kind of high-accuracy tube material after cold-drawn or hot rolling process.Due to precision tube inside and outside wall non-oxidation layer, bear high-pressure non-leakage, in high precision, best bright finish, clod wash be indeformable, enlarging, flattening free from flaw etc. a little, so being mainly used to produce the product of pneumatically or hydraulically element, such as cylinder or oil cylinder, can be seamless pipe, also have welded pipe.The chemical composition of precision tube has carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
But, currently used precision tube intensity is the highest, and fragile, Construction and Maintenance are the easiest, and service life is short.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of combined precision steel pipe, has intensity high, is hardly damaged, and Construction and Maintenance are easy, service life length advantage.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of combined precision steel pipe, including: 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 described steel pipe body is disposed with the first described resistance to compression layer and described microporous calcium silicate layer inside from outward, and the outer surface of described steel pipe body is disposed with the second described resistance to compression layer, described aluminium foil reflecting layer and described corrosion-resistant coating outward from interior.
In a preferred embodiment of the present invention, the first described resistance to compression layer is iron milltailings cementing paste filling material layer.
In a preferred embodiment of the present invention, the second described resistance to compression layer is plant fiber foam material layer.
In a preferred embodiment of the present invention, the thickness of the second described resistance to compression layer is more than the thickness of the first described resistance to compression layer.
The invention has the beneficial effects as follows: it is high that the present invention has intensity, is hardly damaged, Construction and Maintenance are easy, service life length advantage.
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 structural representation of combined precision steel pipe one of the present invention preferred embodiment；
In accompanying drawing, the labelling of each parts is as follows: 1, steel pipe body, the 2, first resistance to compression layer, and 3, microporous calcium silicate layer, the 4, second resistance to compression layer, 5, aluminium foil reflecting layer, 6, corrosion-resistant coating.
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 combined precision steel pipe, including: steel pipe body the 1, first resistance to compression layer 2, microporous calcium silicate layer the 3, second resistance to compression layer 4, aluminium foil reflecting layer 5 and corrosion-resistant coating 6, the inner surface of described steel pipe body 1 is disposed with the first described resistance to compression layer 2 and described microporous calcium silicate layer 3 inside from outward, and the outer surface of described steel pipe body 1 is disposed with the second described resistance to compression layer 4, described aluminium foil reflecting layer 5 and described corrosion-resistant coating 6 outward from interior.
In the present invention, the first described resistance to compression layer 2 is iron milltailings cementing paste filling material layer.
In the present invention, the second described resistance to compression layer 4 is plant fiber foam material layer.
In the present invention, the thickness of the second described resistance to compression layer 4 is more than the thickness of the first described resistance to compression layer 2.
Combined precision steel pipe of the present invention provides the benefit that: it is high that the present invention has intensity, is hardly damaged, and Construction and Maintenance are easy, service life length advantage.
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.
