HRSG P91 T91 Piping weld Inspection Recommendations
HRSG P91 T91 Piping weld Inspection Recommendations
(OP)
I am interested in any information that involves the lifetime of HRSG welds in high energy piping or how often these welds should be inspected. The piping uses P91 and T91 steel and in the HP sections of the HRSG temps of over 1000 F and pressures of over 900 psi. More specifically I am interested in the life of the welds and when the welds should periodically be inspected. I have been searching and have not came across any good information, although I have learned a lot about the subject.
If you can help in any way, it would be greatly appreciated.
Thanks
