Abstract

The invention provides a stainless steel composite pipe. The stainless steel composite pipe comprises a hollow stainless steel pipe, a carbon steel pipe and a plastic pipe, wherein the hollow stainless steel pipe is sleeved with the carbon steel pipe, the carbon steel pipe is sleeved with the plastic pipe, and an anti-corrosion coating is arranged in the hollow stainless steel pipe. The stainless steel composite pipe has the following technical advantages that the stainless steel inner wall cannot be corroded through the anti-corrosion coating, the rigidity of the stainless steel pipe is improved through the carbon steel pipe, and the stainless steel pipe is protected through the plastic pipe.

Description

A kind of stainless steel composite pipe
Technical field
the present invention relates to a kind of stainless steel composite pipe, belong to Stainless Steel Products technical field.
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, in the time that bending, twisting strength are identical, weight is lighter, so be also widely used in manufacturing machine part and engineering structure.Also be commonly used for and produce various conventional weapons, gun barrel, shell etc.
Existing stainless-steel pipe, inwall is easily corroded, and maintenance load is large.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of stainless steel composite pipe is provided.
Stainless steel composite pipe of the present invention, comprises hollow Stainless Steel Tube, is enclosed within the carbon steel tubing on hollow Stainless Steel Tube and is enclosed within the plastic tube on carbon steel tubing, in described hollow Stainless Steel Tube, is provided with corrosion resistant coating.
The shape of cross section of described hollow Stainless Steel Tube, carbon steel tubing and plastic tube is identical, is circle, square or irregular shape.
Stainless steel composite pipe of the present invention, has following technique effect: 1) corrosion resistant coating makes stainless steel inner wall anti-corrosive; 2) carbon steel tubing increases Stainless Steel Tube rigidity; 3) plastic tube plays the effect of protection Stainless Steel Tube.
Brief description of the drawings
Fig. 1 is the sectional view of stainless steel composite pipe of the present invention.
Wherein, 1 is hollow Stainless Steel Tube, and 2 is carbon steel tubing, and 3 is plastic tube, and 4 is corrosion resistant coating.
Embodiment
As shown in Figure 1, stainless steel composite pipe of the present invention, comprises hollow Stainless Steel Tube 1, is enclosed within the carbon steel tubing 2 on hollow Stainless Steel Tube 1 and is enclosed within the plastic tube 3 on carbon steel tubing 2, in described hollow Stainless Steel Tube 1, is provided with corrosion resistant coating 4.Described hollow Stainless Steel Tube 1, carbon steel tubing 2 are identical with the shape of cross section of plastic tube 3, are circle, square or irregular shape.
By reference to the accompanying drawings embodiments of the present invention are described in detail above, but the invention is not restricted to above-mentioned mode of execution, in the ken possessing at affiliated technical field those of ordinary skill, can also under the prerequisite that does not depart from aim of the present invention, make a variety of changes.
