Abstract
The utility model discloses a kind of overall titanium-steel pipe cold exchange device, formed by titanium-steel pipe plate and titanium-steel pipe, be characterized in that titanium pipe is after all base tubes and Tube-sheet Welding, carry out again entirety compound, by the exterior angle automatic TIG Welding Machine of base tube and tube sheet, strengthen the intensity of the attachment weld of heat exchanger tube and tube sheet, avoid base tube welding to produce high temperature local titanium has been caused to oxidation, titanium pipe and clad tubesheet titanium layer carry out seal welding by titanium ring, ensure to be titanium layer with medium contact face, prevent corrosion.The serviceability of a kind of overall titanium-steel pipe cold exchange device of the utility model is higher.
Description
Technical field
The utility model relates to one and is applied to the industries such as oil, chemical industry, metallurgy, electric power, completes thermal medium condensation or cooling equipment, specifically a kind of overall titanium-steel pipe cold exchange device.
Background technology
The cold exchange device using in petroleum chemical industry, because processing medium contains a large amount of H
2s, C0
2, Cl
-deng corrosive medium, therefore the feature of tubing used is except having higher-strength and rigidity, also should have the ability of resistance to above-mentioned dielectric corrosion.The heat exchanger tube that current most of cold exchange device adopts is multiple tube, can address the above problem.The technique of current known production multiple tube has mechanical drawing, mechanical stitch, hydraulic expanding-forming, Aeroform method etc.But current known process is to be mainly used in transport line or pipeline seamless steel pipe.What adopt through the full titanium composite corrosion resistant heat exchanger of patent searching CN 201277833Y is that a kind of titanium-steel pipe is as heat exchange element; after adopting titanium protective layer flange, coating direct and titanium composite plate welds; because base tube and tube sheet weld; the intensity that cannot ensure tube head weld seam is not suitable for bearing device, has the different of internal from the scope of application of the present utility model.
Utility model content
The technical problem that the utility model solves is: be to provide a kind of manufacturing process convenient, improve the welding quality at tube head weld seam titanium pipe position, guarantee the cold exchange device of tube head weld strength.The utility model can be used for the two-chamber such as shell-and-tube heat exchanger, air cooling heat exchanger bearing device.
Process of the present utility model is: 1. first base tube is penetrated to composite ti pipe plate and position, adopt the groove place of basic unit of tungsten electrode argonaut welding base tube morning and tube sheet to weld, carry out butt welded seam and carry out Non-Destructive Testing after having welded.2. coating titanium pipe is penetrated in base tube, titanium pipe stretches out base tube length 3～6mm.All heat exchanger tubes are carried out to entirety compound.3. after all heat exchanger tube composite testings, carry out argon arc seal welding at the coating groove place of titanium tube and tube plate.
The advantage of a kind of overall titanium-steel pipe cold exchange device of the utility model is: known multiple tube generally adopts single tube compound, be usually used in transport line or pipeline seamless steel pipe, and on cold exchange device, for guaranteeing the intensity of multiple tube and tube sheet attachment weld, base tube must carry out intensity welding with tube sheet, if multiple tube is first carried out after compound welding again, the high temperature producing due to base tube and tubesheet intensity welding can cause the oxidation of local titanium, thereby reduces the decay resistance of titanium.Therefore, the serviceability of a kind of overall titanium-steel pipe cold exchange device of the utility model is higher.
Brief description of the drawings
Fig. 1 is the schematic diagram of a kind of overall titanium-steel pipe heat exchanger tube of the utility model.
Fig. 2 is the welding schematic diagram of a kind of overall titanium-steel pipe cold exchange device heat exchanger tube of the utility model and tube sheet.
Detailed description of the invention
In accompanying drawing 1, a kind of overall titanium-steel pipe heat exchanger tube is made up of titanium-steel pipe plate 1, titanium-steel pipe 2, deflection plate 3.According to the difference of tube bank specification, the quantity of heat exchanger tube is not consistent yet.
Accompanying drawing 2 is welding schematic diagrames of a kind of overall titanium-steel pipe cold exchange device heat exchanger tube of the utility model and tube sheet, after 3 welding of base tube (carbon steel or steel alloy) 2-2 and titanium-steel pipe plate, by titanium pipe 2-1 penetrate in base tube 2-2, carry out compound.Because titanium and steel can not direct molten welderings, because liquid lower titanium can produce intermetallic compound and seriously embrittlement with steel.Therefore between titanium-steel pipe plate 3 and titanium pipe 2-1, a titanium ring 4 is set, titanium pipe 2-1 and titanium ring 4 and titanium-steel pipe plate 3 carry out seal welding, make to connect reliable, sealing is tight, ensure to be titanium layer with medium contact face simultaneously, prevent corrosion, improve the whole service life of equipment.
The utility model is compared with known common cold exchange device, as heat exchanger composite steel tube, except it should have certain intensity and corrosion resistance, the contact interface of its two-layer steel pipe should reach complete metallurgical binding, in the hope of good thermal conductivity, both can save precious metal, can reduce investment outlay again.Therefore composite steel tube uses and will be subject to the extensive use of domestic petroleum, chemical industry, machine industry on cold exchange device as a kind of cheap and good-quality new structural material.
The utility model technique advanced person, reliable, manufacture simple, Yi Hang, show by practical experience, can effectively prevent all kinds of defects of multiple tube in assembling and welding process, particularly effectively avoided the high temperature being produced by base tube and Tube-sheet Welding to cause the problem of oxidation of titanium pipe.A kind of overall titanium-steel cold exchange device multiple tube cold exchange device can, for the two-chamber such as shell-and-tube heat exchanger, air cooling heat exchanger bearing device, can be applied to the field such as oil, chemical industry.
