Book Description
The susceptibility of six stainless steels to stress corrosion has been determined by exposing self-stressed specimens indoors and outdoors at ambient temperatures and also at 550 F (56l K). The salt-coated stainless steels were resistant to stress corrosion cracking at 550 F (56l K) for exposures from 4000 to 10,000 hours. Specimens of AM-350 DA and AM-367 stainless steel were found to be very susceptible to stress-corrosion cracking with exposures less than 5000 hours in both the indoor (with a salt coating) and outdoor (with and without a salt coating) environments, while the AM-350 CRT, AISI 501, PH l5-7 Mo, and PH 14-8 Mo displayed excellent resistance. In general, the stainless steels with higher austenite contents appeared to have better resistance to the corrosive effects of salt, both at rooni temperature and at 550 F (56l K).

Book Description
The susceptibility of austenitic 304 stainless steel to aqueous or dilute acid attack at ambient and elevated temperatures has been investigated. It is found that, unlike aluminum alloys, this material under the conditions investigated is not embrittled by pre-exposure to water vapour and it is concluded that this is due to the inability of hydrogen to permeate the oxide surface film during static testing. Slow strain rate testing in dilute acid, under free corrosion or cathodic potential, has shown that hydrogen embrittlement is an important factor in the intergranular stress corrosion cracking of austenitic stainless steel. Cathodic charging of thin foils with hydrogen was found to promote the formation on martensite and intergranular cracks. (Author).

Book Description
“Process Plant Equipment Book is another great publication from Wiley as a reference book for final year students as well as those who will work or are working in chemical production plants and refinery...” -Associate Prof. Dr. Ramli Mat, Deputy Dean (Academic), Faculty of Chemical Engineering, Universiti Teknologi Malaysia “...give[s] readers access to both fundamental information on process plant equipment and to practical ideas, best practices and experiences of highly successful engineers from around the world... The book is illustrated throughout with numerous black & white photos and diagrams and also contains case studies demonstrating how actual process plants have implemented the tools and techniques discussed in the book. An extensive list of references enables readers to explore each individual topic in greater depth...” –Stainless Steel World and Valve World, November 2012 Discover how to optimize process plant equipment, from selection to operation to troubleshooting From energy to pharmaceuticals to food, the world depends on processing plants to manufacture the products that enable people to survive and flourish. With this book as their guide, readers have the information and practical guidelines needed to select, operate, maintain, control, and troubleshoot process plant equipment so that it is efficient, cost-effective, and reliable throughout its lifetime. Following the authors' careful explanations and instructions, readers will find that they are better able to reduce downtime and unscheduled shutdowns, streamline operations, and maximize the service life of processing equipment. Process Plant Equipment: Operation, Control, and Reliability is divided into three sections: Section One: Process Equipment Operations covers such key equipment as valves, pumps, cooling towers, conveyors, and storage tanks Section Two: Process Plant Reliability sets forth a variety of tested and proven tools and methods to assess and ensure the reliability and mechanical integrity of process equipment, including failure analysis, Fitness-for-Service assessment, engineering economics for chemical processes, and process component function and performance criteria Section Three: Process Measurement, Control, and Modeling examines flow meters, process control, and process modeling and simulation Throughout the book, numerous photos and diagrams illustrate the operation and control of key process equipment. There are also case studies demonstrating how actual process plants have implemented the tools and techniques discussed in the book. At the end of each chapter, an extensive list of references enables readers to explore each individual topic in greater depth. In summary, this text offers students, process engineers, and plant managers the expertise and technical support needed to streamline and optimize the operation of process plant equipment, from its initial selection to operations to troubleshooting.
