Abstract
The invention discloses a steel pipe for a hydraulic supporting column. The steel pipe comprises a steel pipe body, a first expansion-resisting composite material layer, a nickel-based high-temperature alloy layer, a second expansion-resisting composite material layer and a Nb-Ti-C-B system niobium-based composite material layer; the first expansion-resisting composite material layer and the nickel-based high-temperature alloy layer are sequentially arranged on the outer surface of the steel pipe body from inside to outside, and the second expansion-resisting composite material layer and the Nb-Ti-C-B system niobium-based composite material layer are sequentially arranged on the inner surface of the steel pipe body from outside to inside; and according to the above manner, the steel pipe is good in high-temperature-expansion-resistant property and pressure resistance and long in service life.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of steel pipe for hydraulic prop.
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 steel pipe high temperature resistance expansion character being currently used for hydraulic prop is poor, and compressive resistance poor performance, 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 hydraulic prop, and high temperature resistance expansion character is good, and compressive resistance performance is good, and service life is long.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of steel pipe for hydraulic prop, including: steel pipe body, first anti-expansion composite layer, nickel base superalloy layer, second anti-expansion composite layer and Nb-Ti-C-B system niobio composite layer, the appearance of described steel pipe body is disposed with described first anti-expansion composite layer and described nickel base superalloy layer outward from interior, the interior table of described steel pipe body is disposed with described second anti-expansion composite layer and described Nb-Ti-C-B system niobio composite layer inside from outward.
In a preferred embodiment of the present invention, the first described anti-expansion composite layer is Zr2P2WO12/ Ni composite layer.
In a preferred embodiment of the present invention, the thickness of the first described anti-expansion composite layer is identical with the thickness of the described second anti-expansion composite layer.
In a preferred embodiment of the present invention, the thickness of the first described anti-expansion composite layer is more than the thickness of the second described anti-expansion composite layer.
The invention has the beneficial effects as follows: high temperature resistance expansion character of the present invention is good, and compressive resistance performance is good, and service life is long.
Accompanying drawing explanation

Referring to Fig. 1, the embodiment of the present invention includes:
A kind of steel pipe for hydraulic prop, including: steel pipe body the 1, first anti-expansion composite layer 2, nickel base superalloy layer the 3, second anti-expansion composite layer 4 and Nb-Ti-C-B system niobio composite layer 5, the appearance of described steel pipe body 1 is disposed with described first anti-expansion composite layer 2 and described nickel base superalloy layer 3 outward from interior, and the interior table of described steel pipe body 1 is disposed with described second anti-expansion composite layer 4 and described Nb-Ti-C-B system niobio composite layer 5 inside from outward.
In the present invention, the first described anti-expansion composite layer 2 is Zr2P2WO12/ Ni composite layer.
In the present invention, the thickness of the first described anti-expansion composite layer 2 is identical with the thickness of the described second anti-expansion composite layer 4.
In the present invention, the thickness of the first described anti-expansion composite layer 2 is more than the thickness of the second described anti-expansion composite layer 4.
The present invention provides the benefit that for the steel pipe of hydraulic prop: high temperature resistance expansion character of the present invention is good, and compressive resistance performance is good, 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.
