Description
Technical field
The utility model relates to a kind of cold roll seamless steel tubing in different shapes.
Background technique
Seamless steel pipe has hollow section, 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, it 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 manufactures ring-shaped work pieces with steel pipe, stock utilization can be improved, simplify manufacturing process, save material and machining period, as rolling bearing lasso, very heavy top cover etc., extensive steel pipe manufactures.
The production technology of general seamless steel pipe can be divided into cold-drawn and hot rolling two kinds, the wall thickness of cold rolling seamless steel is generally little than hotrolling seamless pipe, but surface seems brighter than thick-walled seamless steel pipes, surface does not have too many coarse, and bore does not have too many burr yet.
But there is following problem in current steel pipe: comprehensive mechanical performance is poor, and intensity is low, and oxidation resistance is poor, and wear-corrosion resistance is poor.
Model utility content
In order to overcome the problems referred to above, it is good that the utility model provides a kind of comprehensive mechanical performance, and intensity is high, the cold roll seamless steel tubing in different shapes that oxidation resistance is good and wear-corrosion resistance is good.
The technological scheme that the utility model is adopted for achieving the above object is:
A kind of cold roll seamless steel tubing in different shapes, comprises steel pipe body, and described steel pipe body cross-section outside is square, and inside is circular; Described steel pipe inner body wall is provided with graphite layer, and the outer wall of steel pipe body is provided with plating tungsten layer, and described plating tungsten layer outside is provided with anticorrosive coat.
Described anticorrosive coat is epoxy coating.
The wall thickness of described steel pipe body is 20 ~ 28mm.
Described plating tungsten layer thickness is 3 ~ 8mm.
The thickness of described graphite layer is 5mm ~ 8mm.
The thickness of described epoxy coating is 2mm ~ 5mm.
Described steel pipe body material is selected from the one in WB36, Cr5Mo, 15Mo3, T91, P91.
the beneficial effect of model utility:
Comprehensive mechanical performance is good, and intensity is high, and oxidation resistance is good and wear-corrosion resistance is good, and adopt the design of square-outside and round-inside, while making steel pipe have good bending performance, fluid is little at pipe internal friction, increases circulation area.
Accompanying drawing explanation
Fig. 1 is the anti-structural representation of the utility model.
In figure, 1, steel pipe body; 2, graphite layer; 3, tungsten layer is plated; 4, anticorrosive coat.
