Abstract
The invention discloses a large-diameter precision steel pipe comprising a steel pipe body, a first nano composite plated layer, a first corrosion resistant alloy layer, a second nano composite plated layer, and a second corrosion resistant alloy layer. An inner surface of the steel pipe body is covered with the first nano composite plated layer and the first corrosion resistant alloy layer in order from outside to inside, while an outer surface of the steel pipe body is covered with the second nano composite plated layer and the second corrosion resistant alloy layer in order from inside to outside. In such a way, the large-diameter precision steel pipe is good in corrosion resistance and not easy to damage in a highly corrosive environment, and has a long service life.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of heavy caliber precision tube.
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 heavy caliber precision tube poor corrosion resistance, fragile in the environment that corrosivity is strong, service life is short.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of heavy caliber precision tube, corrosion resistance and good, is hardly damaged in the environment that corrosivity is strong, and service life is long.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of heavy caliber precision tube, including: steel pipe body, the first nano-composite plate, the first corrosion resisting alloy layer, the second nano-composite plate and the second corrosion resisting alloy layer, the inner surface of described steel pipe body be disposed with the first described nano-composite plate and the first described corrosion resisting alloy layer inside from outward, the outer surface of described steel pipe body be disposed with the second described nano-composite plate and the second described corrosion resisting alloy layer outward from interior.
In a preferred embodiment of the present invention, the first described nano-composite plate is Ni-P-nanometer ZrO2Chemical composite plating.
In a preferred embodiment of the present invention, the second described nano-composite plate is Ni-La2O3Nano-composite plate.
In a preferred embodiment of the present invention, the first described corrosion resisting alloy layer is Fe-Cr-Mo-C-B alloy-layer.
The invention has the beneficial effects as follows: corrosion resistance and good of the present invention, being hardly damaged in the environment that corrosivity is strong, service life is long.

Referring to Fig. 1, the embodiment of the present invention includes:
A kind of heavy caliber precision tube, including: steel pipe body the 1, first nano-composite plate the 2, first corrosion resisting alloy layer the 3, second nano-composite plate 4 and the second corrosion resisting alloy layer 5, the inner surface of described steel pipe body 1 be disposed with the first described nano-composite plate 2 and the first described corrosion resisting alloy layer 3 inside from outward, the outer surface of described steel pipe body 1 be disposed with the second described nano-composite plate 4 and the second described corrosion resisting alloy layer 5 outward from interior.
In the present invention, the first described nano-composite plate 2 is Ni-P-nanometer ZrO2Chemical composite plating.
In the present invention, the second described nano-composite plate 4 is Ni-La2O3Nano-composite plate.
In the present invention, the first described corrosion resisting alloy layer 3 is Fe-Cr-Mo-C-B alloy-layer.
Heavy caliber precision tube of the present invention provides the benefit that: corrosion resistance and good of the present invention, is hardly damaged in the environment that corrosivity is strong, and service life is long.
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.
