FAILURE ANALYSIS OF TUBE SIDE INTERCONNECTING
NOZZLES
A Finite Element Analysis (FEA) was performed in support of a
failure analysis of the cracks/failure of the tube side interconnecting
nozzles using brick elements. The Finite Element Model (FEM) consisted
of nozzles, saddles, tube-sheets, body flanges, tubes, relevant
tube side heads, shells and inlet channels. A transient thermal
stress analysis was performed to determine the transient state
of stresses. The state of stresses was used in determination of
the fatigue life of the area of concern.
