Abstract
The utility model discloses a composite pipe, which includes a carbon steel base pipe covered by a stainless steel sleeve, wherein the wall thicknesses of the carbon steel base pipe and the stainless steel sleeve are 1.2mm and 0.3 to 0.5mm respectively. The composite pipe is applicable to the pipes of the outdoor body-building apparatus, the vertical pipes of the bicycle/motorcycle handlebars and the saddle pipes, has high strength, excellent bearing capability and long service life, and can ensure rust-preventing and corrosive-resistant excellent performances under the condition that the electroplating or the spray coating technologies are not used.
Description
Technical field
The utility model relates to a kind of composite pipe, concrete relates to a kind of composite pipe that is used for outdoor fitness equipments tubing, bicycle/motorcycle handle riser and seatpillar.
Background technique
At present; Employed tubing all is to be material with carbon steel in existing outdoor fitness equipments tubing, bicycle/motorcycle handle riser and the seatpillar; Make needed shape through bent tube technique then, after methods such as electroplating surface or spraying are carried out surface treatment, make final required product at last again.Carbon steel have advantages such as structural strength height, bearing capacity are strong, but exist the overlay coating weatherability poor, come off and shortcoming such as working life is short easily.And the plating of being adopted among the preparation process, spraying coating process can be to the bigger pollutions of environment generation.
The model utility content
For overcoming the problems of the prior art, the purpose of the utility model is to provide a kind of composite pipe, and this composite pipe not only has the high and strong advantage of bearing capacity of carbon steel structural strength, tube surfaces non-corrosive, corrosion-resistant, long service life simultaneously.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the utility model has adopted following technological scheme:
A kind of composite pipe, it comprises a carbon steel parent tube, said carbon steel parent tube is coated with the stainless steel pipe box.
Preferably, the wall thickness of said carbon steel parent tube is 1.2mm.
Preferably, the wall thickness of said stainless steel pipe box is 0.3-0.5mm.
Compared with prior art the utlity model has following advantage:
The composite pipe of the utility model is applicable to employed tubing in outdoor fitness equipments tubing, bicycle/motorcycle handle riser and the seatpillar; Have intensity height, good, the long service life of bearing capacity, and under the situation that need not pass through plating or spraying coating process, just can guarantee non-corrosive, corrosion resistant premium properties.
Above-mentioned explanation only is the general introduction of the utility model technological scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the sectional view of the composite pipe of the utility model.
Label declaration among the figure: 1, carbon steel parent tube, 2, the stainless steel pipe box.
Embodiment
Below in conjunction with accompanying drawing and embodiment the technological scheme of the utility model is further explained.
Referring to shown in Figure 1, a kind of composite pipe, it comprises a carbon steel parent tube 1, and said carbon steel parent tube 1 is coated with stainless steel pipe box 2, and the wall thickness of said carbon steel parent tube 1 is 1.2mm, and the wall thickness of said stainless steel pipe box 2 is 0.3-0.5mm.
The composite pipe skin of this enforcement is the SUS304 stainless steel; Internal layer is a SPHC carbon steel; Both proofread and correct, polish prepared such as grinding, scalable pipe and form through volume circle, high frequency welding, coating, argon arc welding, the full circle of special-purpose tube producer, and the same inside with stainless steel of the product appearance that finally makes has the premium properties of carbon steel, and The comprehensive performance is improved; And cost of production has reduced by 30% with respect to existing technology.
The foregoing description is technical conceive and the characteristics for the utility model is described just, its objective is to be the content that lets the one of ordinary skilled in the art can understand the utility model and to implement according to this, can not limit the protection domain of the utility model with this.The variation or the modification of every equivalence of having done according to the essence of the utility model content all should be encompassed in the protection domain of the utility model.
