STRENGTH VERIFICATION OF PIPING SYSTEM EXPOSED TO HARMONIC EXCITATION

Piping systems, which are connected to equipment with rotational parts are, beside normal operating conditions, additionally exposed to harmonic excitation qualified as occasional load and which occurs due to different reasons. This paper presents a completely newly designed piping system connected to gas turbine casing and thus exposed to harmonic excitation caused by the casing's vibrations. Calculation is performed to evaluate and verify if this new piping system is properly designed to be able to take over such additional occasional loads.
