Synopses & Reviews
This book guides through general and fundamental problems of pressure vessel design. It moreover considers also problems which seem to be of lower importance but which turn out to be crucial in the design phase. The basic approach is rigorously scientific with a complete theoretical development of the topics treated, but the analysis is always pushed so far as to offer concrete and precise calculation criteria that can be immediately applied to actual designs. This is accomplished through appropriate algorithms that lead to final equations or to characteristic parameters defined through mathematical equations.
The first chapter describes how to achieve verification criteria, the second analyzes a few general problems, such as stresses of the membrane in revolution solids and edge effects. The third chapter deals with cylinders under pressure from the inside, while the fourth focuses on cylinders under pressure from the outside. The fifth chapter covers spheres, and the sixth is about all types of heads. Chapter seven discusses different components of particular shape as well as pipes, with special attention to flanges. The eighth chapter discusses the influence of holes, while the ninth is devoted to the influence of supports. Finally, chapter ten illustrates the fundamental criteria regarding fatigue analysis.
Besides the unique approach to the entire work, original contributions can be found in most chapters, thanks to the author's numerous publications on the topic and to studies performed ad hoc for this book.
1 Industrial Sectors Interested in Pressure Vessels Pressure vessels are probably the most widespread machines within the di?erentindustrialsectors.Infact, thereisnofactorywithoutpressurevessels, steam boilers, tanks, autoclaves, collectors, heat exchangers, pipes, etc. More speci?cally, pressure vessels represent fundamental components in sectors of enormous industrial importance, such as the nuclear, oil, petrochemical, and chemical sectors. There are periodic international symposia on the problems related to the veri?cation of pressure vessels. FormanyyearsanISOcommitteewasdedicatedtopressurevesselsdesign. There is also a technical committee of the EU speci?cally assigned to this ?eld. All the industrialized countries have a code relative to pressure vessels design.However, evenwhenthecodeincludesspeci?cregulationstodetermine the thickness of the di?erent components, typically not all issues facing the designer are discussed. Finally, it is worth noting that a few regulations cause some perplexity. In Italy, a speci?c area of ISPESL regulations (VSR collection) is devoted to pressure vessels. 2 Current Know-How with Regard to Resistance Veri?cation A pressure vessel is not an easy machinery in terms of resistance veri?cation. A layman can easily make the mistake of considering somewhat simple str- turalformsthatareinfactquitedi?culttoanalyze, especiallyifonewouldlike to apply the most modern criteria of veri?cation (elastoplasticity, self-limiting stresses, etc.). Regardless of the enormous interest in the topic and numerous e?orts, many problems have not been studied in-depth, and there is still no agr- ment among scholars and the institutions of the various countries that de?ne VI Preface regulations. In addition, economical reasons and technical progress constantly present new challenges in connection with new forms and solutions, the necessity to reduce thickness to a minimum, etc."
