Pipe Stress Analysis

   We know that some pipes are subjected to high pressure & high temperature. Also pipes carry the load of the flowing fluid.

·         We need to check & confirm that the pipe is not going to fail with these loads.

·         This process of checking the stress developed in the piping due to various loading is called Pipe Stress Analysis/Flexibility analysis.

·         In the process of analysis we apply various postulated loading on the pipe & find out the stress resulted from these loading.

·         Then we check with governing codes if those stresses generated are acceptable or not.

·         We check support load & movement for various loading condition.

·         We also check out the terminal point loading generated from pipe to the equipment connected to the pipe. This loading is to be within acceptable limits of the equipment suggested by the vendors.

·         We also find out the pipe growth due to change in temperature & need to keep the movement of pipe within acceptable limits.

·         Pipe stress analysis is an Interactive & Iterative process. Each step is checked.

·         If check fails we have to go back, modify the layout & restart the analysis.
