Abstract

The utility model relates to a metal composite pipe with a layer-shaped structure. One layer or multiple layers of composite material tubes are combined in and out of a metal base material tube with the materials of low carbon steel, carbon steel, or stainless steel. The composite material tubes adopts a copper tube, an aluminum tube, a nickel tube, a titanium tube, a niobium tube, an alloy tube, or a stainless steel tube. Two or more than two kinds of metal tubes are abutted together in the method of extruding, rolling, drawing, reducing a diameter, or expanding a diameter with a tapered core head through an inner hole of a tube. The utility model has different characteristics of base materials and composite materials, and has higher performance and higher price ratio.

Description

Making laminated composite metal pipe

The utility model relates to a kind of metal composite pipe with stratiform structure.

Existing metal pipe is generally single-layer metal, is difficult to satisfy simultaneously and requirement that price low beautiful to the strength of materials, corrosion resistance or outward appearance in the engineering.

The utility model purpose is according to material different qualities and the different requirements of use, selects to have the processing method of maximum combined face and least cost, and a kind of different materials of engineering demands and the type metal composite pipe of class are provided.

The utility model project organization is: a kind of making laminated composite metal pipe, in the base material pipe of low-carbon steel or carbon steel, stainless steel or outside be combined with one or more layers multiple material pipe.Multiple material pipe can adopt copper pipe, aluminum pipe, nickel pipe, titanium pipe, zirconium pipe, niobium pipe, tantalum pipe, Stainless Steel Tube or other alloy pipe.Fit together between base material pipe and the composite pipe.

The utility model adopts two or more tubular metals, by extruding, rolling, drawing undergauge or with the taper core print by the bloated routing method of pipe orifice, two-layer or two-layer above tubular metal fitted tightly together and obtain.Adopt cheap ferrous metal pipe to make base material, adopt coloured, rare metal or the stainless steel material of writing in reply, it thereby have base material concurrently and the composite wood different qualities, have superior performance price ratio, can be widely applicable for different industries and field.

Accompanying drawing is the utility model structural representation.

Embodiment 1: the stratiform composite pipe selects base material mainly with cheap and to have the intensity and the favorable manufacturability that can satisfy usage requirement can be foundation, so generally select Low Carbon Steel Pipe, carbon steel tubing or Stainless Steel Tube in the ferrous metal pipe.Selecting multiple material serves as according to compound with base material to satisfy different Environmental Conditions with different usage requirements mainly.So multiple material adopts nonferrous metal tube, rare metal pipe or Stainless Steel Tube again, specifically as steel pipe, aluminum pipe, nickel pipe, titanium pipe, zirconium pipe, niobium pipe, tantalum pipe and alloy pipe thereof etc.Select the composite pipe of rational base material pipe and multiple material pipe manufacturer can carry out bending, flange, welding or further plastic working, can layering, cracking, produce the crape folding, can satisfy tension, the compressive strength of usage requirement.The processing method of composite metal pipe is elastic modulus difference and the processibility according to base material Guan Yufu material pipe, and multiple material is in difference interior or outside, select undergauge processing or the footpath processing of expanding, when the Young's modulus of material is less than base material again, multiple material is at skin, then need expand and directly process, when internal layer, then need undergauge processing.Take drawing or pressing method to produce the pipe of thick composite bed earlier, take to subtract wall method rolling or drawing again and make tube wall total thickness attenuate, to make thin composite bed composite pipe.Making laminated composite metal pipe can manufacture the pipe of all size and the steel tubing in different shapes of different section shape, its radial dimension 10～600mm, and the thinnest composite bed thickness 〉=0.2mm, length can reach processing and be equipped with all lengths that allows.

Claims

1, a kind of making laminated composite metal pipe, it is characterized in that in the base material pipe of low-carbon steel or carbon steel, stainless steel or outside be combined with one or more layers multiple material pipe.

2,, it is characterized in that multiple material pipe can adopt copper pipe, aluminum pipe, nickel pipe, titanium pipe, zirconium pipe, niobium pipe, tantalum pipe, Stainless Steel Tube or other alloy pipe according to the layered metal composite pipe of claim 1.

3, making laminated composite metal pipe according to claim 1 is characterized in that fitting together between base material pipe and the composite pipe.
