Pipe stress analysis calculates the stress in a piping system subject to normal operating loads such as
pressure, weight, and thermal expansion, and occasional loads such as wind, earthquake, and water
hammer. Because all piping systems are connected to equipment such as vessels, tanks, pumps, turbines,
and compressors, the piping stress analysis also involves evaluation of the effect of the piping
forces and moments to the connecting equipment. As the piping stress is controlled by the arrangement
of the supports and restraints, the scope of piping stress includes also pipe supports.
