Background technology
The application that belongs to multiple tube is mainly based on economy and aim of saving, and the specific use on various device.For example, require to possess the pressure vessel, pipeline of resistance to corrosion etc., adopting the stainless steel tube manufacturing more reasonable, but the cost height; If adopt the same pressure vessel of normal carbon steel pipe and the compound multiple tube manufacturing that makes of stainless steel tube, pipeline etc., the thickness of stainless steel tube only integral thickness 2～10%, so not only satisfy the corrosion resistance and the sufficiently high intensity of container, and reduced cost greatly.In addition, some has the metal material of superior heat resistance, corrosion-resistant and conduction, heat conductivility, as copper, manganese, titanium or chromium etc., the problem that has scarcity of resources, if adopt bilayer or multi-layered composite pipe, not only help saving resource, also can satisfy the special requirement in a lot of engineerings.
At present, metal composite pipe mainly is to adopt mechanical complex method processing and manufacturing, as hydraulic pressure composite algorithm, drawing composite algorithm etc., or adopting the welding composite algorithm etc. of clad steel plate bending welding, the shortcoming that the multiple tube that hydraulic pressure composite algorithm and drawing composite algorithm are produced exists is: the back poor processability of processing cost height, multiple tube (can not bend, processing such as folding, weldering, pressure); The shortcoming that the multiple tube that the welding composite algorithm is produced exists is: because there is the osmosis between the different metal element in the welding of composite bed end face, influence the serviceability of multiple tube.
Summary of the invention
The object of the present invention is to provide a kind of new method of making multiple tube in the metal, it is lower to utilize in the cold rolling continuous welding metal of this method preparation multiple tube to have a cost, and cycling processability is good, of many uses.
The object of the present invention is achieved like this: the manufacture method of multiple tube in a kind of cold rolling continuous welding metal, may further comprise the steps successively: (1) determines the size of metal coil tape, and described metal coil tape is meant the brazing hot rolled metal coiled composite that adopts the separated outer layer parent metal roll coil of strip and the internal layer plied timber roll coil of strip or formed by the outer parent metal roll coil of strip and the internal layer plied timber roll coil of strip; (2) uncoiling; (3) cold rolling moulding in the tubulation unit; (4) be welded into pipe; (5) cut after the finishing; Wherein: step (3) is that fixed expander in 2～3 roads is housed in the tubulation unit, makes internal layer plied timber band 1～3mm outside seam after outer parent metal band becomes pipe is stretched out on the two side seams limits of Cheng Guanhou by calendering during cold rolling moulding.
The outer parent metal roll coil of strip of the present invention comprises the carbon steel roll coil of strip or the steel alloy roll coil of strip, and the described internal layer plied timber roll coil of strip comprises the stainless steel roll coil of strip, copper strips volume or titanium strip coil etc.
Step of the present invention (4) should be selected 1～2 welding according to the thickness of tube wall, to guarantee welding effect.
The invention provides the technology of multiple tube in the metal that a kind of technology is simple, production cost is low, by multiple tube in the cold rolling continuous welding metal of the inventive method production, its mechanical performance, Corrosion Protection and cycling processability are good, have solved metal composite pipe and have welded different element infiltration problems; Metal composite pipe is widely used industrial, can produces huge economic benefit and social benefit.
