Abstract
The utility model belongs to the field of heat exchangers in the industry of petrochemical industry and discloses a steel-aluminum compound pipe. The steel-aluminum compound pipe comprises an inner pipe and an outer pipe compounded on the outer surface of the inner pipe, wherein the inner pipe is a carbon steel pipe; the outer pipe is an aluminum pipe; and the outer surface of the outer pipe is a smooth surface, or a ladder-shaped or arc groove is uniformly formed on the outer surface of the outer pipe. By the steel-aluminum compound pipe, problems that the conventional water cooler is easily corroded and short in service life, the conventional air cooler is easily blocked, high in water consumption, the conventional evaporator is easily corroded and has a bad heat transmission effect and the like are solved; and the steel-aluminum compound pipe can be used for a long time and is high in heat transmission efficiency, the waste of resources is effectively reduced, the using cost is reduced, and frequent overhauling is not required.
Description
Technical field
The utility model relates to a kind of steel aluminium composite pipe, specifically belongs to the field of heat exchangers in the petrochemical industry.
Background technology
The cooler of petrochemical industry use at present mainly adopts following several: (1), employing ordinary carbon steel formula shell water cooler, and water is walked in the pipe, and (or being cooled) medium that is condensed is walked outside the pipe.Advantage is low price, draw materials easily, but when if (or being cooled) medium that is condensed contains the corrosion thing, the tube bank perforation that easily is corroded, and the life-span is very short, and causes the large amount of sewage discharging, and how therefore contaminated environment replaced by air cooler at present; (2), fountain finned tube wet air cooler, heat-transfer effect is better, but this air cooler has two fatal shortcomings: (a), since the fin gap very little, dust storm, foreign material and incrustation scale are easy to stop up fin, but heat-transfer effect descends, (b), water sprays into by side direction, is difficult for penetrating finned-tube bundle.Therefore along with causing lengthen service time, water consumption rolls up; (3), ordinary carbon steel formula baudelot evaporator, this is a kind of optical surface spray air cooler., it overcomes some shortcomings of finned tube wet air cooler, and compact conformation, thermal effect are better.But carbon steel tube bank corrosion under the water and air effect is very fast, causes thermal resistance to strengthen, and heat-transfer effect descends.Have no alternative but to strengthen injection flow rate.The long-term use, tube bank also can be corroded and penetrate.Service life is also only about 1.5-2.If adopt stainless steel tube or other senior anticorrosive material, the cost of tube bank increases a lot.
Summary of the invention
Problems such as the purpose of this utility model provides a kind of steel aluminium composite pipe simple in structure, ingenious, rational, and is short service life with cooler pipeline in the solution prior art, and heat-transfer effect is poor, perishable.
The technical scheme that provides according to the utility model: a kind of steel aluminium composite pipe, pipe and be compound in outer tube on the inner tube outer surface in comprising, described in pipe be carbon steel pipe, outer tube is aluminum pipe, it is characterized in that: the outer surface of described outer tube is shiny surface or is provided with groove.
As further improvement of the utility model, above-mentioned groove is distributed on the outer tube outer surface.
As further improvement of the utility model, above-mentioned groove is trapezoidal shape or circular shape.
As further improvement of the utility model, the thickness of above-mentioned aluminum pipe is 0.2 ~ 0.8mm.
The utility model is to solve the problems that exist of existing water cooler, air cooler, evaporimeter, and, the life-span perishable as water cooler lacks, and air cooler easily stops up, water consumption is big, problems such as evaporimeter is perishable, heat-transfer effect difference.This steel aluminium composite pipe life-span is long, can use for a long time, and the heat transfer efficiency height, the waste that effectively reduces resource has reduced use cost simultaneously and has not needed frequent maintenance.
Description of drawings
The structural representation that Fig. 1 is shiny surface for outer tube-surface of the present utility model.
The structural representation that Fig. 2 is trapezoidal groove for outer tube-surface of the present utility model.
The structural representation that Fig. 3 is arc groove for outer tube-surface of the present utility model.
Fig. 4 is used for the use state diagram of steel aluminium composite cooler for the utility model.
Fig. 5 is steel aluminium composite pipe contour structures schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As Fig. 1 ~ shown in Figure 5, pipe 1, outer tube 2, groove 3, steel aluminium composite pipe 4 etc. in comprising.
As Fig. 1 ~ shown in Figure 5, the utility model is a kind of steel aluminium composite pipe, comprise interior pipe 1 and be compound in interior outer tube 2 of managing on 1 outer surface, described interior pipe 1 is carbon steel pipe, proof strength, the carbon steel pipe inner surface generally adopts shiny surface, outer tube 2 is aluminum pipe, and the thinner thickness of aluminum pipe is between 0.2 ~ 0.8mm, mainly play corrosion-resisting function, the outer surface of described outer tube 2 is shiny surface or is provided with groove 3.
The groove 3 that arranges is distributed on the outer surface of outer tube 2.
Groove 3 can be set to trapezoidal or circular arc, so that strengthen heat-transfer effect.
As shown in Figure 4, steel aluminium composite cooler comprises above-mentioned steel aluminium composite pipe 4, and simultaneously, the steel aluminium composite pipe that is applied to steel aluminium composite cooler usually is processed into snakelike tubulose in production application, is beneficial to increase the heat radiation heat transfer area; Usually by circle or rectangle tube sheet above-mentioned steel aluminium composite pipe is assembled into one, directly adopts the mode that connects or weld that rises that both are fixed together at tube sheet and steel aluminium composite pipe junction.
This steel aluminium composite pipe life-span is long, can use for a long time, and the heat transfer efficiency height, the waste that effectively reduces resource has reduced use cost simultaneously and has not needed frequent maintenance.
Pipe and outer tube can be made cylindrical tube or oval pipe and other non-circular shapes according to producing needs in of the present utility model, all fall in the protection domain of the present utility model.
