Abstract
The utility model discloses a titanium the compound finned air cooler of steel, by tub case and titanium the compound finned tube of steel is constituteed, are its characteristics that the titanium pipe is at all fin parent tube and titanium steel clad tubesheet welding finishing back, adopt the bloated shape method of hydraulic pressure to carry out whole complex again, through fin parent tube and titanium the intensity welding of steel clad tubesheet, strengthened fin parent tube and titanium the intensity of the attachment weld of steel clad tubesheet, avoid the parent tube welding to produce high temperature and led to the fact the oxidation to local titanium, titanium pipe and titanium steel clad tubesheet titanium layer encircles through the titanium and carries out seal welded, guarantee to be the titanium layer with the medium contact surface, corrosion prevention. The utility model relates to a titanium the performance under corrosion -resistant operating mode is higher for the compound finned air cooler of steel.
Description
Technical field
This utility model belongs to a kind of for oil, chemical industry, the air cooling equipment of coal chemical technology, a kind of is mainly used in the air cooler that petrochemical industry medium contains the corrosive mediums such as H2S, C02, Cl-.
Background technology
The air cooler used in petroleum chemical industry, owing to some processes medium contains the corrosive mediums such as substantial amounts of H2S, C02, Cl-, therefore the feature of tubing used is in addition to have outside higher-strength and rigidity, also should have the ability of resistance to above-mentioned dielectric corrosion.The heat exchanger tube that major part cold exchange device is used at present is multiple tube, it is possible to resolve the problems referred to above.The technique of currently known production multiple tube has mechanical pull, mechanical stitch, hydraulic expanding-forming, Aeroform method etc..But currently known process is mainly used in transport line or pipeline seamless steel pipe.A kind of titanium-steel pipe is used as heat exchange element through the full titanium composite corrosion resistant heat exchanger of patent searching CN 201277833Y; directly weld with the coating of titanium composite panel after using titanium protective layer flange; owing to base tube welds with tube sheet; cannot ensure that the intensity of tube head weld seam is not suitable for bearing device, have the different of internal from range of the present utility model.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of titanium-steel composite fin tube air cooler, improves the corrosion resistance of finned tube, it is ensured that the air cooler of tube head weld seam titanium pipe position welding quality.
For achieving the above object, a kind of titanium-steel composite fin tube air cooler that this utility model provides is made up of bobbin carriage, titanium-steel composite fin tube, and feature is provided with titanium pipe in being fin base tube, improves the corrosion resistance of finned tube.Being penetrated into by titanium pipe in fin base tube, titanium pipe stretches out fin base tube length 3～6mm, uses hydraulic expanding-forming method to carry out all fin base tubes overall compound after titanium pipe welds with titanium-steel pipe plate.
The advantage of a kind of titanium of this utility model-steel composite fin tube air cooler is: known multiple tube typically uses single tube to be combined, it is usually used in transport line or pipeline seamless steel pipe, and on air cooler, for guaranteeing the intensity of titanium-steel composite fin tube and titanium-steel pipe plate attachment weld, fin base tube must carry out strength solder joints with titanium-steel pipe plate, if welded again after first carrying out being combined to multiple tube, owing to the high temperature of fin base tube with titanium-steel pipe plate strength solder joints generation can cause the oxidation of local titanium, thus reduce the decay resistance of titanium.Therefore, the serviceability of a kind of titanium of this utility model-steel composite fin tube air cooler is higher.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of titanium of this utility model-steel composite fin tube air cooler；
Fig. 2 is that a kind of titanium of this utility model-steel composite fin tube air cooler titanium-steel composite fin tube welds schematic diagram with titanium-steel pipe plate；
Detailed description of the invention
In accompanying drawing 1, a kind of titanium-steel composite fin tube air cooler is made up of bobbin carriage 1, titanium-steel composite fin tube 2.According to the difference of air cooler specification, the quantity of finned tube is the most consistent.
Accompanying drawing 2 is that this utility model one titanium-steel composite fin tube air cooler titanium-steel composite fin tube welds schematic diagram with titanium-steel pipe plate, after fin base tube (carbon steel or steel alloy) 2-2 welds with titanium-steel pipe plate 3, titanium pipe 2-1 is penetrated in fin base tube 2-2 and carry out overall being combined.Due to titanium and steel can not direct molten weldering because titanium and steel can produce intermetallic compound and serious embrittlement under liquid.Therefore arranging one piece of titanacycle 4 between titanium-steel pipe plate 3 and titanium pipe 2-1, titanium pipe 2-1 carries out sealing and welds with titanacycle 4 and titanium-steel pipe plate 3, makes connection reliable, seal tight, ensure to be titanium layer with medium contact surface simultaneously, prevent corrosion, improve the whole service life of equipment.
This utility model is compared with known common air cooler, as air cooler composite fin tube, in addition to 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 preferable heat conductivity, both can save precious metal, can reduce investment outlay again.Therefore composite fin tube uses by domestic petroleum, chemical industry, the extensive application of machine industry on air cooler as a kind of cheap and good-quality new structural material.
This utility model technique is advanced, reliable, be simple to manufacture, easy, shown by practical experience, can effectively prevent the titanium-steel composite fin tube all kinds of defects in assembling and welding process, particularly effectively prevent and welded the high temperature of generation with titanium-steel pipe plate by fin base tube and cause the problem of oxidation of titanium pipe.A kind of titanium-steel composite fin tube air cooler can be widely applied to the field such as oil, chemical industry.
