Hello all,

Does anybody know which pipe grade can be used for equivalent of ASTM A335 P36?
We need to change the grade with alternative one because of market unavailability.

Main important thing is pipe will work under 400 celcius degree and 250-300 bar.

Equivalent grades can be also in European norms but it should not be 1.6368 grade, because this is not also available at market.

Thanks

Suggest that you repost in the "Pipelines, piping and Fluid Mechanic's" forum

Cuz....

"Main important thing is pipe will work under 400 celcius degree and 250-300 bar."

As the high-energy piping design engineer, you are responsible for this .... not a bunch of strangers from the internet

@mjcronin i was not responsible for piping design, i am only in a position need to submit alternative grade to piping engineer due to required material grade unavailability in the market. Still thanks for your message.

You need to go back to the designer; we don't know why it was selected.
It may be strength, weldability, creep, or some other characteristic.
There are many similar grades, but unless you know the constraints you can't make a selection.
