Abstract
The invention discloses a composite metal tube, which comprises an interlayer with a stainless steel tube as a substrate, a brass tube lining arranged on the inner wall of the stainless steel tube, and a carbon steel tube arranged on the surface of the stainless steel tube. The method employs the harmless, corrosion resistant and high pressure resistant brass as the tube surface in contact with drink, and is helpful for ensuring the safety and health when users have a drink. Besides, the brass amount is small, and the cost is low. The stainless steel tube covered on the exterior of the brass tube is used for stabilizing the shape of the brass tube, so as to prevent the brass tube from damage, while the external carbon steel tube protects the stainless steel tube and the brass tube from being corroded or damaged to a certain degree.
Description
Technical field
The present invention relates to a kind of metal pipe, be specifically related to a kind of composite metal pipe.
Background technique
At present in factories such as milk, beer, beverages, to the delivery pipe on the delivery line of raw materials such as milk, beer, beverage and product, use be copper pipe.The raw material and the product of the pipeline transporting milk that couples together with copper pipe, beer, beverage; Do not contain harmful impurity though can make in raw material and the product of conveying, the raw material that has guaranteed to carry and the quality of product are because the raw material of copper is more and more nervous; Price is handed over costliness again; And mechanical strength is lower, and is when raw material when coming processings such as transporting milk, beer, beverage with the delivery line of copper pipe and product, also not satisfactory.
To carrying the running water pipe of tap water; What generally use is the carbon steel tubing that is coated with the zinc layer on the inner tube wall; Because metallic zinc is harmful, also be unfavorable with the carbon steel tubing that is coated with the zinc layer on the inner tube wall as the delivery pipe of tap water, after long-term the use unavoidably corrosion can appear; Influence the quality of potable water, thus infringement people's physical and mental health.For this reason, people have designed a kind of plastic-aluminum pipe that adopts metal and plastics to be composited, and attempt to substitute present widely used galvanized pipe with this.Though this aluminium-plastic composite pipe has effectively solved the corrosion problem in the galvanized pipe, because its manufacture cost is higher, accessory such as its joint all need manufacture and design again in addition, so very difficultly at present promote the use of in large area.
Conveyance conduit of today also exists various etching problems, and this has also increased freight to a certain extent.
Summary of the invention
The object of the present invention is to provide the composite metal pipe pipe of a kind of resistant to rust, safety and sanitary.
Technological scheme of the present invention is: a kind of composite metal pipe, described composite metal pipe comprise with the Stainless Steel Tube being the mesosphere of matrix, and stainless steel inside pipe wall is provided with the brass tube liner, is provided with carbon steel tubing at stainless steel pipe surface.
In preferred embodiment of the present invention, the thickness of described Stainless Steel Tube is 0.1 millimeter-1 millimeter.
In preferred embodiment of the present invention, the thickness of described brass tube is 0.05 millimeter-0.5 millimeter.
In preferred embodiment of the present invention, described Stainless Steel Tube, brass tube and carbon steel tubing are under molten state, to fit together.
According to the invention is a kind of composite metal pipe, adopts harmless, corrosion-resistant, high voltage bearing brass to process the contact tube face of beverage, helps the safety and sanitary that guarantee that the user drinks; In addition, the brass consumption is few, and is with low cost; The outside shape that adopts Stainless Steel Tube to stablize brass tube of brass tube; Prevent that brass tube from damaging, outer field carbon steel tubing has then played the certain protection effect, the corrosion and the damage of protection stainless steel and brass tube.
Description of drawings
Fig. 1 is the structural representation of this composite metal pipe in composite metal pipe one preferred embodiment of the present invention;
Each annex mark is following among the figure: 1, Stainless Steel Tube, 2, brass tube, 3, carbon steel tubing.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
According to the invention is a kind of composite metal pipe; As shown in Figure 1: according to the invention is a kind of composite metal pipe; This composite metal pipe comprises that with Stainless Steel Tube 1 be the mesosphere of matrix, and Stainless Steel Tube 1 inwall is provided with brass tube 2 liners, is provided with carbon steel tubing 3 on Stainless Steel Tube 1 surface.The thickness of used Stainless Steel Tube 1 is best results between 0.1 millimeter-1 millimeter, and the thickness of brass tube 2 is best between 0.05 millimeter-0.5 millimeter, and the thickness of carbon steel tubing 3 is seen landform is required thickness is adjusted.Stainless Steel Tube 1, brass tube 2 and carbon steel tubing 3 make through specialized mould processing, and under molten state, Stainless Steel Tube 1, brass tube 2 and carbon steel tubing 3 are fit together, thus the condensed state that is integral.
According to the invention is a kind of composite metal pipe, adopts harmless, corrosion-resistant, high voltage bearing brass to process the contact tube face of beverage, helps the safety and sanitary that guarantee that the user drinks; In addition, the brass consumption is few, and is with low cost; The outside shape that adopts Stainless Steel Tube to stablize brass tube of brass tube; Prevent that brass tube from damaging, outer field carbon steel tubing has then played the certain protection effect, the corrosion and the damage of protection stainless steel and brass tube.
The above is merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed; Variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
