Description
Technical field
The invention belongs to stainless steels and carbon steel composite tube technology of preparing neighborhood, and in particular to it is a kind of it is easy welding apply side it is stainless
The preparation method of steel and carbon steel composite tube.
Background technology
Stainless steel and carbon steel composite tube are a kind of widely used composite bimetal pipes, and giving full play to, base tube carbon steel layer is excellent
The feature for covering that pipe stainless steel layer is corrosion-resistant, wear-resisting and specious is remained while good mechanical mechanics property, is saved
Material.Space is had a wide range of applications in oil, petrochemical industry and the stronger environment of marine corrosive.
Stainless steel and carbon steel composite tube in actual use, the connectivity problem of bimetal tube is always current skill
Art problem.Especially pipeline of the diameter between 100mm-200mm causes existing since the ingredient properties of two kinds of metals are different
Welding technique it is difficult to ensure that welding quality.Application No. is 201210408747.1 patent applications to disclose a kind of stainless steel
Combined Welding takes over and its manufacturing method, is first to weld middle layer using protection weldering, then use stainless steel electrode in its patent document
Stainless steel cladding welding is welded out in a manner of argon arc welding welding, is then used carbon steel to exchange submerged arc welding and is gone out carbon steel weldering
Seam.This technology is when welding two pieces unlike material, very airplane crash.And production efficiency is low, and cost increases.
Existing composite tube welding technology, different-metal material welding base, transition zone, coating use different welding methods, make
Increase at the welding difficulty increase of stainless steel composite pipe, inefficiency, cost.
Invention content
It is an object of the present invention to provide the preparation methods that the stainless steel composite pipe on side is applied in a kind of easy welding, can be efficiently against both
There is disadvantage present in technology.
The invention is realized in this way, it is characterised in that implementation is as follows：
（1）Using application No. is a kind of 201610078667.2, entitled " manufactures of the easy deposited side stainless steel clad plate of welding
The stainless steel of method " manufacture makees blank with carbon steel composite board；
（2）The surrounding of above-mentioned stainless steel and carbon steel composite board is applied into side milling and goes out the welding groove that angle α is 45 ° -60 °, sand is used in combination
The impurity such as wheel polishing removal iron scale, make surfacing, as shown in Figure 1；
（3）It is detected a flaw with carbon steel composite board to above-mentioned stainless steel using ultrasonic wave, the JCO methods of forming is used on bend pipe shaping apparatus
The tubulose of opening is bent to stainless steel clad plate, and composite plate both ends stainless steel of the same race is made to apply the groove opening on side after bending
Distance d is 10-15mm, as shown in Figure 2；
（4）Using welding methods such as argon arc welding or agitating friction welderings along the stainless steel of stainless steel after bending and carbon steel composite tube base
It is welded on deposited side；
（5）Machinery expanding：Soldered stainless steel composite pipe is heated to 1050 DEG C -1150 DEG C, it is enterprising in diagonal rolling expanding pipe
Row oblique milling thermal expansion, expanding relative quantity are 50% -70%；
（6）Carry out subsequent heat treatment and tube surfaces polishing.
Advantage of the present invention and good effect：
With advantages of the present invention compared with conventional method：The present invention solves current double layer of metal multiple tube difficulty welding, efficiency
Low problem.The double layer composite board that steel plate both ends are high strength stainless steel materials of the same race is produced first, is then bent to stainless
Steel pipe, and be welded to connect, this method is more advantageous to the welding between multiple tube.To simplified two layers of multiple tube
Welding procedure improves production efficiency.
