![]() The discussion is heavily weighted to the stress analysis of piping systems in nuclear power plants, since this type of piping has the most stringent requirements. This chapter discusses several aspects of piping stress analysis. B5) based on the selected locations and types and the applied loads. The piping supports are then designed (Chap. Possible support locations and types must be iterated until all stress requirements are satisfied and other piping allowables (e.g., nozzle loads, valve accelerations, and piping movements) are met. Once the piping layout is finalized, the piping support system must be determined. If necessary, layout solutions should be iterated until a satisfactory balance between stresses and layout efficiency is achieved. The layout of the piping system should be performed with the requirements of piping stress and pipe supports in mind (i.e., sufficient flexibility for thermal expansion proper pipe routing so that simple and economical pipe supports can be constructed and piping materials and section properties commensurate with the intended service, temperatures, pressures, and anticipated loadings). Senior Engineering Specialist Bechtel Power Corporation Frederick, Maryland Piping stress analysis is a discipline which is highly interrelated with piping layout (Chap.
