Failure of Carbon steel pipes at high temperature
Failure of Carbon steel pipes at high temperature
(OP)
What type of failure occurs when the temperature of fluid though a carbon steel pipe goes up?
Say above 800 F or 400 C?

What exactly is your question ?
Plain carbon steel piping can provide many. many years of service at 400F and very short service, ending with catastrophic failure at 800 C.
Most piping codes limit carbon steel usage to a maximum continuous service temperature of about 775F (~412C)
At 800C (1472F) a phenom known as graphitization quickly occurs.
This has been discussed many times on this forum in the past.....

I messed up the units. Actually I meant 400 C (~800F).
@MJCronin,
Can you please explain why do "most piping codes limit carbon steel usage to a maximum continuous service temperature of about 775F (~412C)"?
What type of failure is observed at temperature higher than this?
