Abstract
Nowadays, time saving in piping stress analysis is a major concern among consultant engineering companies in power and process plants. In this paper, we are going to have a quantity review between some important parameters such as sustained, occasional and expanding stresses with total length and nozzle load of a real case according to ASME B31.3. Most of the times, piping stress designers try different and more flexible piping routes completely arbitrary. Longer piping route means greater mass, and it means a big trouble in earthquake time especially for allowable nozzle loading, on the other hand shorter piping route increases thermal nozzle loading and operating stresses. We will try to find a relationship among mentioned parameters to have an optimal piping route in order to save time and material. Finally, different routes will be analyzed using Caesar II to plot related parameters and find optimum criterion.
