Pipe Stress Analysis

Definition and Purpose

In the past, when industry developed, many plants were constructed, many problems with piping system, many scientists and engineers had to research to find out the reason and write into standards or codes.

For a long time, now, human have had codes which are appropriate for each country, each area.

Pipe Stress Analysis is the last step before approving the design for fabricate, and work in construction.

Pipe Stress Analysis is the way to ensure your plants, your piping systems safety, economic and effective.

Developing together with computer technology and numerical methods, especially, finite element method. Nowadays, technical programs could do a simulation, a calculation, a result presentation in a short time. This is helpful for a analysis quickly and accurate.

Pipe Stress Analysis included:

• Calculate stresses in a piping system and compare them with code allowable
• Evaluate the loads on rotating equipment nozzles and casting
• Evaluate the loads on nozzles on heat exchangers, pressure vessels or tank
• Evaluate the loads on structural anchors
• Evaluate the loads on pipe supports
• Evaluate piping movements from thermal expansion or contraction
• Evaluate the effects of wind loads on the piping system and attached equipment
• Evaluate the effects earthquake loads on the piping system and attached equipment
• Evaluate the effects of wave loads on the piping system and attached equipment
• Evaluate the effects of soil resistance to piping system movements and stresses
• Evaluate the effects of changes in temperature, pressure, and weight on flanged connections to identify possible flange leakages
