Pipe Stress Analysis

-
Image
 Pipe Stress Analysis: The purpose of pipe stress analysis is to ensure the safe operation of piping systems by verifying their structural and pressure retaining integrity under the loading conditions expected to occur during the life time of the piping in the plant. This is accomplished by calculation of stress in the pipe wall, piping expansion movements, equipments, nozzle loads and system natural frequencies and comparing these values to the permissible values.   The stress analyst is also responsible for determining the design support loads to ensure that the supports are adequately designed to take the piping loads. Considerations: The requirements of piping stress analysis are laid out in the piping code ASME B31. For the purpose of stress analysis, piping systems are typically divided in to two main categories and then further divided into sub categories.  Basically they are classified as HOT and COLD systems . Hot lines are those with a design temperature of...
