Abstract
The utility model belongs to the technical field of pipelines and particularly relates to a stainless steel composite steel pipe. The utility model aims to solve the technical problem that the design is not reasonable enough in the prior art. The stainless steel composite steel pipe comprises a pipe body and is characterized in that the pipe body comprises an inner pipe body, a middle pipe body and an outer pipe body, wherein the inner pipe body is made of stainless steel; the middle pipe body is made of carbon steel; the outer pipe body is made of the stainless steel; and the inner pipe body, the middle pipe body and the outer pipe body are sheathed in sequence to be fixed together. Compared with the prior art, the stainless steel composite steel pipe has the advantages that the design is reasonable, the structure is simple, the mechanical strength is high, and the service life is long.
Description
Technical field
The utility model belongs to the pipe technology field, especially relates to a kind of stainless steel composite pipe.
Background technique
Stainless Steel Tube is a kind of rectangular circular steel of hollow, mainly is widely used in industrial conveyance conduit such as oil, chemical industry, medical treatment, food, light industry, machinery instrument and machine structural parts etc.In addition, in bending, when twisting strength is identical, weight is lighter, so also be widely used in manufacturing machine part and engineering structure.
For example; The Chinese patent document discloses a kind of Stainless Steel Tube [application number: CN98229473.5]; As outer tube, its transverse section is circular, oval, rectangle or abnormity with Stainless Steel Tube, its pipe is inboard be provided with one fit with its inwall, be the internal lining pipe that material is processed by plastics or iron sheet.It has the exterior decorative effect identical with the common stainless steel pipe, and cheap characteristics are arranged, and is applicable to the occasion of plastics or iron sheet at the tube fluid medium, more shows its superiority.
Though such scheme has solved the partial technical problems that existing technology exists, it is reasonable inadequately still to exist design, and heat resistance is relatively poor, the cost height, and rigidity is low, technical problems such as through walls, buried character difference.In addition, existing technology is paid attention to the improvement of inboard wall of tube body usually, but has ignored outside antiseptic and rustproof performance.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of reasonable in design, simple in structure, stable and reliable for performance, the stainless steel composite pipe of long service life.
For achieving the above object; The utility model has adopted following technical proposal: this stainless steel composite pipe; Comprise body; It is characterized in that described body comprises the interior tube body processed by stainless steel, the middle body of being processed by carbon steel and the outer tube body of being processed by stainless steel, described interior tube body, middle body and outer tube body socket successively are fixed together.
In above-mentioned stainless steel composite pipe, the thickness ratio of described interior tube body, middle body and outer tube body is 1: 4: 1.
Compared with prior art, the advantage of this stainless steel composite pipe is: reasonable in design, simple in structure, mechanical strength is high, long service life.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Among the figure, body 1, interior tube body 11, middle body 12, outer tube body 13.
Embodiment
As shown in Figure 1; This stainless steel composite pipe comprises body 1; This body 1 comprises the interior tube body 11 processed by stainless steel, the middle body of being processed by carbon steel 12 and the outer tube body of being processed by stainless steel 13, and described interior tube body 11, middle body 12 and outer tube body 13 socket successively are fixed together.The thickness ratio of interior tube body 11, middle body 12 and outer tube body 13 is 1: 4: 1.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as body 1, interior tube body 11, middle body 12, outer tube body 13 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
