Factors Affecting Selection of Tubes of Heat Exchanger

Selecting appropriate materials for heat exchangers are included in the duties of designer and manufacturer engineers of heat exchangers. In this paper, various alloys which are used in producing tubes of heat exchangers have been studied and the water effects on them have been discussed. The operation and maintenance effects on the tubes with different alloys and the factors affecting heat exchangers design have been also presented. Further, the most appropriate selection of tube material and sheet have been introduced which is obtained with regard to these factors. The best and most suitable tube material and sheet as well as fluid optimum speed in the tube or converters shell can be selected through information presented in this article.
