Abstract
The utility model belongs to a heat-exchanging unit, which specifically is a carbon steel calorisation heat exchanger, comprising a heat exchange tube arranged on a baffle board and a tube plate, the utility model is characterized in that both the inner surface and outer surface of the heat exchanger are processed with a carbon steel calorisation alloy layer. Compared with the prior art, the utility model employs a structural style of carbon steel calorisation alloy layer of comparatively low price in the processing of the inner surface and outer surface of common tubular products, the carbon steel aluminizing alloy layer has the same erosion resistance as expensive high alloy resistant materials, the costs of the heat exchange tube of the same unit reduces in a vast scale, thereby the utility model has the advantages of low manufacturing costs and good erosion-resisting characteristics.
Description
The utility model belongs to heat exchanger-type, specifically is a kind of carbon steel tube heat exchanger.
Development along with the China's oil chemical engineering industry, the needed equipment supporting with it and the specific (special) requirements of parts are also got more and more, corrosion resistance promptly is one of topmost specific (special) requirements of each petrochemical equipment, the heat exchanger of the prior art heat exchanger tubes that adopt expensive high alloy resistant material to make more, and heat exchanger tube is the critical piece in the heat transmission equipment, so not only the cost height of heat exchanger tube, machined difficulty are big, increase manufacturing, the use cost of equipment, also strengthened the cost of final products virtually.
The purpose of this utility model is to provide a kind of low cost of manufacture, the carbon steel tube heat exchanger that corrosion resistance is good.
The utility model is achieved through the following technical solutions:
Be a kind of carbon steel tube heat exchanger, comprise the heat exchanger tube that is installed on deflection plate and the tube sheet, it is characterized in that the inside and outside surface of heat exchanger tube all is processed with the carbon steel tube alloy-layer.
The carbon steel tube alloy layer thickness on the inside and outside surface of above-mentioned heat exchanger tube is 0.1～0.2mm, and this heat exchanger tube can adopt general common tubing.
The utility model compared with prior art, adopted the version of the carbon steel tube alloy-layer of relative low price on the inside and outside Surface Machining of common tubing, the carbon steel tube alloy-layer has and the same resistance to corrosion of expensive high alloy resistant material, but the manufacturing of heat exchanger tube and machined are realized easily, the cost of same units heat exchanger tube reduces significantly, thereby has reduced manufacturing, the use cost of equipment greatly.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model heat exchanger tube embodiment schematic cross-section.
Fig. 2: the utility model example structure schematic diagram.
As shown in Figure 1, this carbon steel tube heat exchanger comprises the heat exchanger tube 2 that is installed on deflection plate 5 and the tube sheet 4, it is characterized in that the inside and outside surface of heat exchanger tube 2 all is processed with carbon steel tube alloy- layer 1,3.
Carbon steel tube alloy- layer 1,3 thickness on the inside and outside surface of above-mentioned heat exchanger tube 2 are 0.1～0.2mm, and this heat exchanger tube 2 can adopt general common tubing.
As shown in Figure 2, there is the tubing of carbon steel tube alloy- layer 1,3 to be assembled into one in inside and outside Surface Machining shown in Figure 1 by tube sheet 4 and deflection plate 5, promptly constituted a heat-exchanging tube bundle, then this heat-exchanging tube bundle is assembled, used and get final product as other heat exchanger tube, the highly corrosive of materials such as carbon steel tube alloy- layer 1,3 can high temperature resistance sulphur, hydrogen sulfide and high-temperature naphthenic acid, the tubing that is processed with carbon steel tube alloy- layer 1,3 can be widely used in the shell-and-tube heat exchanger of various models.
