Abstract
The utility model relates to a modular nonrust steel pipe, including the seamless body of stainless steel that has hollow structure, install the carbon steel body on the inner wall of the seamless body of stainless steel, install anticorrosion inside lining body on the inner wall of carbon steel body, for the interference fit installation between the seamless body of carbon steel body and stainless steel, also install for interference fit between anticorrosion inside lining body and the carbon steel body. The utility model relates to a rationally, simple structure, temperature resistance behavior be good, low in manufacturing cost, and have characteristics such as the rigidity is good, corrosion resisting property is good, mechanical strength height.
Description
Technical field
The utility model relates to not metal pipe technical field, specifically refers to a kind of Stainless Steel Tube, particularly relates to a kind of assembled steel pipe.
Background technique
Stainless-steel pipe is a kind of rectangular circular steel of hollow, is mainly widely used in industrial transportation pipe line and the machine structural parts etc. such as oil, chemical industry, medical treatment, food, light industry, machinery instrument.In addition, when bending, twisting strength are identical, lighter in weight, so be also widely used in manufacturing machine part and engineering structure.Stainless Steel Tube is normally manufactured by cold rolling and cold-drawing method, needs one end of Stainless Steel Tube to break into microcephaly, being convenient to Stainless Steel Tube to be inserted mould and carrying out cold-drawn, excising the end head through beaing after cold-drawn again during cold-drawn.
It is reasonable not that Stainless Steel Tube of the prior art also exists design, heat resistance is poor, cost is high, the technical problems such as rigidity is low, and through walls, buried character is poor, when at some special flowing medium environment, under etching condition as various acid, alkali, salt, need there is higher requirement to the material of steel pipe, and at the bottom of its rigidity, bad mechanical strength.
Model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of assembled steel pipe.
The utility model is achieved in that
A kind of assembled steel pipe, comprise the stainless steel jointless body with hollow structure, the inwall of described stainless steel jointless body is provided with carbon steel body, the inwall of described carbon steel body is provided with corrosion protection liner body, for interference fit is installed between described carbon steel body and stainless steel jointless body, also for interference fit is installed between described corrosion protection liner body and carbon steel body.
Further, the thickness of described stainless steel jointless body, carbon steel body and corrosion protection liner body successively decreases successively.
Further, the thickness of described stainless steel jointless body is 3mm-4mm.
Further, the thickness of described carbon steel body is 2mm-3mm.
Further, the thickness of described corrosion protection liner body is 1mm-2mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, structure is simple, heat resistance is good, low cost of manufacture, and has good rigidly, corrosion resistance and good, mechanical strength high.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model;
Fig. 2 is sectional view of the present utility model.
In figure: 10-stainless steel jointless body; 20-carbon steel body; 30-corrosion protection liner body.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1 and Fig. 2, Fig. 1 is sectional view of the present utility model, and Fig. 2 is sectional view of the present utility model.
Described a kind of assembled steel pipe, comprise the stainless steel jointless body 10 with hollow structure, the inwall inwall of described stainless steel jointless body 10 being provided with carbon steel body 20 described in carbon steel body 20 is provided with corrosion protection liner body 30, for interference fit is installed between described carbon steel body 20 and stainless steel jointless body 10, also for interference fit is installed between described corrosion protection liner body 30 and carbon steel body 20.By being provided with corrosion protection liner body 30, can be used in various industry in practice, especially under the etching condition of various acid, alkali, salt, there is good corrosivity.
The thickness of described stainless steel jointless body 10, carbon steel body 20 and corrosion protection liner body 30 successively decreases successively, further, the thickness of described stainless steel jointless body 10 is 3mm-4mm, the thickness of described carbon steel body 20 is 2mm-3mm, and the thickness of described corrosion protection liner body 30 is 1mm-2mm.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
