Piping Engineering and its equipments lead for 25% of total investment in all chemical, process, LPG/ CNG Plant, oil and pharmaceutical plants.

After the plant layout design the Pipe stress analysis engineers play a vital role in finalizing what the piping engineers have designed. The piping engineers get the approval of the pipe stress analysis team and then only proceed with the detailing.

Selection criteria for lines subject to comprehensive stress analysis, Design temperature, Environmental temperature, Design pressure, Vibration, Loads, Bending moment on valves, flanges and mechanical joints, Flexible joints, Cold springing, Spring supports, Loads from piping systems on equipment are all explained in detail in this Pipe stress analysis course module.
