Engineering Specialties Used:
Radiant section tubes in a large heater were deforming
excessively near the returns and there was a concern for tube
rupture. Multiple changes had been made to the system during the
last turnaround, so there was more than one likely candidate
for the observed behavior. There was a need to understand
the cause of the deformations, a prediction regarding
expected future deformations and a remediation action plan.
Operating Heater Internals
Finite Element Model of the Heater Tubes
By understanding the cause of the observed deformation, and expected future behavior, the heater was able to remain in operation, thus preventing an unscheduled shut down. Argos Engineers is ready to partner with your operations personnel. Only shut down when needed and continue operating safely, and with confidence, when possible. Our personnel have been performing fitness-for-service evaluations of critical systems for over twenty years. Let us provide the analysis input needed for confident decision making.
