SFRC factor for 250000 h - problem in finding the design stress
SFRC factor for 250000 h - problem in finding the design stress
(OP)
Hello,
How can i find the design stress in the creep range for a superheated steam pipeline that exceeded 200000h of operation?
I have the mean value of creep rupture strength (SRTt)at 250000h operating time (given by the material norm), but EN 13480 gives no factor for finding the design stress for pipelines that worked over 200000h.
Thanks,
Codrut

US standards (ASME, API) only go as far as 100000h of lifetime. I think that says allot about equipment working over 200000h (in my case).
