Abstract

The utility model discloses a metallurgy type bimetal composite pipe, which resolves the problem of high temperature delivery of corrosive media and simultaneously resolves the problem that a base pipe and a lining pipe are easy to be bulged or separated when pipelines are required to be bent or punched. The metallurgy type bimetal composite pipe is characterized in that a carbon steel pipe is connected with a stainless steel pipe in a metallurgy mode, generally, means of high temperature, high pressure and the like are adopted, a metallurgical interface is formed between base metal and lining metal, atoms of the interface between the base pipe and the lining pipe can be diffused mutually, and connection strength is higher. A stainless steel joint is exposed on the end surface of the pipe and has corrosion resistant ability. In addition, the metallurgy type bimetal composite pipe is widely applicable to the fields of petroleum, chemical engineering and the like.

Description

Metallurgical formula composite bimetal pipe
Affiliated technical field
The utility model designs a kind of conveyance conduit, belongs to metallurgical formula composite bimetal pipe.
Background technique
Existing conveyance conduit kind is a lot, when conveying has Korrosionsmedium, all adopts carbon steel and rustless steel double-metal composite pipe.What use on the market now is the mechanical double metal composite pipe basically, advantage with its low cost of manufacture, in low temperature, long-distance transport pipes, obtained using comparatively widely, but under high-temperature condition or pipeline need the next meetings of situation such as bending, perforate phenomenons such as bulge, separations of base lining to occur, cause decay resistance decline.
The model utility content
The purpose of this utility model is exactly in order to need to provide under the situations such as bending, perforate a kind of metallurgical formula composite bimetal pipe in high temperature conveying or pipeline.
The utility model reaches by the following technical programs: metallurgical formula composite bimetal pipe, form by carbon steel tube and Stainless Steel Tube, it is characterized in that: the metallurgical connection between carbon steel tube and the Stainless Steel Tube, the Stainless Steel Tube two ends are connected with stainless joint, stainless joint and carbon steel tube and Stainless Steel Tube all by the weld seam welding, can be provided with screw thread on the stainless joint.
The beneficial effects of the utility model are:
This metallurgy formula composite bimetal pipe, owing to link together by metallurgical mode between carbon steel tube and the Stainless Steel Tube, generally adopt means such as High Temperature High Pressure, thereby form metallurgical interface between the basic lining metal, atom interdiffusion mutually between the interface of parent tube and bushing pipe, its join strength is higher.What the pipeline end face was exposed is stainless joint, has corrosion resistance.When high temperature was carried, perhaps pipeline needed under the crooked situation, and phenomenons such as bulge, the separation of base lining can not appear in this kind composite pipe, can guarantee the overall corrosion resistance energy of pipeline.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among Fig. 1,1. stainless joint, 2. carbon steel tube, 3. Stainless Steel Tube, 4. weld seam, 5. screw thread, 6. weld seam.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
By shown in Figure 1, metallurgical formula composite bimetal pipe, form by carbon steel tube 2 and Stainless Steel Tube 3, the metallurgical connection between carbon steel tube 2 and the Stainless Steel Tube 3, Stainless Steel Tube 3 two ends are connected with stainless joint 1, stainless joint 1 welds by weld seam 4 with carbon steel tube 2, welds by weld seam 6 with Stainless Steel Tube 3, can be provided with screw thread 5 on the stainless joint 1.
