SUMMARY
The discussion centers on the recertification requirements for a pressure vessel originally certified to ASME Section VIII, Div 1, designed for 100 psi at 200°F, now operating at 30 psi and 260°F. Key considerations include whether the vessel has been in service, the presence of lethal substances, the ability to obtain wall thickness measurements, and the allowable stress of the construction material at the new temperature. It is concluded that recertification is likely unnecessary if compliance with ASME code calculations is demonstrated for the new operating conditions.
