A 335 P23 vs P91 at 567oC
(OP)
Do you have any experience with comparing P23 and P91 for steam lines connecting boiler to turbine (400 t/h, 130 bar abs at 567oC)? Is P23 already used in certain extent? Any idea of their costs in USA or Europe or Japan($/kg)?
Thanks a lot

P23 was anyway a better choice than P91 or P92? Can you tell me why?

In terms of tubing, I have been involved in their selection and recommended T23 where tube replacement would occur with greater frequency. This would enable the Owner to replace tubes without PWHT and thereby reduce maintenance costs not to mention initial fabrication costs.
