Description
Technical field
The utility model relates to steel pipe field, particularly relates to a kind of seamless steel pipe for hydropneumatic steel cylinder.
Background technique
Seamless steel pipe is that one has hollow section, periphery does not have jointed rectangular steel.Steel pipe has hollow section, and a large amount of pipeline being used as conveying fluid, as the pipeline etc. of transfer oil, rock gas, coal gas, water and some solid material.Steel pipe is compared with the solid steel such as round steel, when bending resistance twisting strength is identical, lighter in weight is a kind of economic section steel products, be widely used in manufacturing structure part and mechanical parts, as the steel scaffold etc. in oil drill rocker, truck drive shaft, bicycle frame and construction.Manufacture ring-shaped work pieces with steel pipe, can improve stock utilization, simplify manufacturing process, save material and machining period, as rolling bearing lasso, very heavy top cover etc., extensive steel pipe manufactures at present.Steel pipe or the indispensable material of various conventional weapon, gun barrel, gun barrel etc. are all wanted steel pipe to manufacture.
But the seamless steel pipe wear-resisting property now for hydropneumatic steel cylinder is poor, and working life is short, and accuracy of manufacturing is low.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of seamless steel pipe for hydropneumatic steel cylinder, has wear-resisting property good, long service life, the advantage that accuracy of manufacturing is high.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of seamless steel pipe for hydropneumatic steel cylinder, comprise: steel pipe body, heat resistance nanometer Antifriction Composites layer, carbon-fibre reinforced epoxy resin layer, Ni-Mn-Ga polymer matrix composites layer and metal tantalum coating, the outer surface of described steel pipe body is enclosed with described heat resistance nanometer Antifriction Composites layer, the internal surface of described steel pipe body is coated with described metal tantalum coating, the internal surface of described metal tantalum coating is disposed with described carbon-fibre reinforced epoxy resin layer and described Ni-Mn-Ga polymer matrix composites layer.
In the utility model preferred embodiment, the wall thickness of described steel pipe body is 0.5 ~ 16mm.
In the utility model preferred embodiment, the thickness of described heat resistance nanometer Antifriction Composites layer is 0.3 ~ 1mm.
In the utility model preferred embodiment, the thickness of described metal tantalum coating is 0.05 ~ 0.1mm.
The beneficial effects of the utility model are: the utility model is provided with multilayer functional material layer on the body of steel pipe, have wear-resisting property good, long service life, the advantage that accuracy of manufacturing is high.
