Abstract
The utility model belongs to the technical field of machinery, relating to tubing and in particular to a novel stainless steel tube. The stainless steel tube comprises a hollow tube body and is characterized in that an inner layer made of plastic is attached on the inner wall of the tube body; an anti-rust coating is attached on the outer wall of the tube body; and both the thickness of the inner layer and the thickness of the anti-rust coating are no more than 2.0mm. Compared with the prior art, the stainless steel tube has the advantages that firstly, the stainless steel tube is reasonable in design, simple in structure and easy to manufacture; secondly, since plastic has good corrosion resistance, the inner layer can effectively prevent the stainless steel inner wall of the tube from contacting with the outside, thus avoiding damages; thirdly, the anti-rust coating has high mechanical strength and can avoid damages of the stainless steel outer wall of the tube, thus effectively protecting the stainless steel tube; and fourthly, a colored layer can effectively improve the visual effect and at the same time can protect a passivation layer, thereby further prolonging the service life of the stainless steel tube.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to tubing, especially relates to a kind of novel stainless steel pipe.
Background technique
Metal can react with the oxygen in the atmosphere, forms patina on the surface.But the iron oxide that forms on Ordinary Steel can be proceeded oxidation, and corrosion is constantly enlarged, and finally forms hole.In the practice, can utilize paint or sludge proof metal, for example, zinc, nickel and chromium are electroplated and are protected steel surface.But this protection only is a kind of film.If protective layer is destroyed, just following steel begins corrosion.Stainless steel is the steel of chemical etching dielectric corrosions such as weak aggressive medium such as a kind of anti-air, steam, water and acid, alkali, salt.Stainless Steel Tube is a kind of rectangular steel of hollow, is used as the pipeline of conveyance fluid in a large number, as oil, rock gas, water, coal gas, steam etc.In addition, in bending resistance, when twisting strength is identical, weight is lighter, so also be widely used in manufacturing machine part and engineering structure.Also be commonly used for and produce various conventional weapons, gun barrel, shell etc.Stainless Steel Tube is safe and reliable, hygienic environment-protecting, economic and practical, the thin-walled property of pipeline and novel reliably, the succeeding in developing of connecting means simply and easily, make it have the irreplaceable advantage of more other tubing, application in engineering can get more and more, using can be more and more universal, promise well.
Although Stainless Steel Tube has above-mentioned superior function, still exist some shortcomings.For example, general Stainless Steel Tube has been grown internal layer also can get rusty service time.For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of two multiple Stainless Steel Tube [application number: application number: 99226952.0], and it comprises fastened to each other three layers, and wherein internal layer and skin are Stainless Steel Tubes, and the mesosphere is plastics.This two multiple Stainless Steel Tube mechanical strength height, good seal performance, long service life.But its stainless steel material remains and is exposed to outward, and for this reason, the someone adopts the mode of carrying out passivation at stainless steel surfaces to produce protective layer, but usually after the passivation color and luster relatively poor, influence attractive in appearance.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of reasonable in design, simple in structure, has both possessed higher physicochemical property, the novel stainless steel pipe that manufacture cost is lower again.
For achieving the above object, the utility model has adopted following technical proposal: this novel stainless steel pipe, comprise hollow tube body, it is characterized in that, described inboard wall of tube body is attached with the internal layer that is made of plastics, described tube wall is attached with resin layer, and the thickness of described internal layer and resin layer all is not more than 2.0mm.
Because plastics have higher Corrosion Protection, therefore can effectively avoid causing damage with extraneous the contact because of the stainless steel inwall.In addition, resin layer has higher mechanical strength, can not cause the stainless steel outer wall destroyed, effectively plays a protective role.
In above-mentioned novel stainless steel pipe, described internal layer is fixed on the inwall of body by injection moulding or plastic-blasting mode.
In above-mentioned novel stainless steel pipe, described resin layer is the passivating layer that is connected as a single entity with body.
In above-mentioned novel stainless steel pipe, the outer surface of described resin layer also is attached with coloration layer.
Compared with prior art, the advantage of this novel stainless steel pipe is: 1, reasonable in design, simple in structure, be easy to manufacturing.2,, therefore can effectively avoid causing damage with extraneous the contact because of the stainless steel inwall because plastics have higher Corrosion Protection.3, resin layer has higher mechanical strength, can not cause the stainless steel outer wall destroyed, effectively plays a protective role.4, coloration layer can improve visual effect effectively, also can protect passivating layer simultaneously, further increases the service life.
Description of drawings
Fig. 1 is the main TV structure schematic representation that the utility model provides.
Fig. 2 is the sectional structure schematic representation that the utility model provides.
Among the figure, body 1, internal layer 11, resin layer 12, coloration layer 13.
Embodiment
As illustrated in fig. 1 and 2, the novel stainless steel pipe comprises hollow tube body 1, and body 1 inwall is attached with the internal layer 11 that is made of plastics, and body 1 outer wall is attached with resin layer 12, and the thickness of internal layer 11 and resin layer 12 all is not more than 2.0mm.Internal layer 11 is fixed on the inwall of body 1 by injection moulding or plastic-blasting mode.Resin layer 12 is the passivating layer that is connected as a single entity with body 1.The outer surface of resin layer 12 also is attached with coloration layer 13.
The internal layer 11 that plastics are made has higher Corrosion Protection, therefore can effectively avoid causing damage because of the stainless steel inwall with extraneous the contact.Resin layer 12 has higher mechanical strength, can not cause the stainless steel outer wall destroyed, effectively plays a protective role.Coloration layer 13 can improve visual effect effectively, also can protect passivating layer simultaneously, further increases the service life.
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 spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as body 1, internal layer 11, resin layer 12, coloration layer 13 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
