This essential new volume provides background information, historical perspective, and expert commentary on the ASME B31.1 Code requirements for power piping design and construction. It provides the most complete coverage of the Code that is available today and is packed with additional information useful to those responsible for the design and mechanical integrity of power piping. The author, Dr. Becht, is a long-serving member of ASME piping code committees and is the author of the highly successful book, Process Piping: The Complete Guide to ASME B31.3, also published by ASME Press and now in its third edition. Dr. Becht explains the principal intentions of the Code, covering the content of each of the Code's chapters. Book inserts cover special topics such as spring design, design for vibration, welding processes and bonding processes. Appendices in the book include useful information for pressure design and flexibility analysis as well as guidelines for computer flexibility analysis and design of piping systems with expansion joints. From the new designer wanting to know how to size a pipe wall thickness or design a spring to the expert piping engineer wanting to understand some nuance or intent of the Code, everyone whose career involves process piping will find this to be a valuable reference.
