Piping classes
(OP)
Hello everybody!
Can anyone tell me why the primary rating are:
150#
300#
400#
600#
900#
1500#
2500#?
Why there is not 200# or 1000# or any other number...?
How did we get these numbers?
I'm sure there is an explanation like for the ND of pipes (coming from Renard series).
Thanks a lot!

Just to say I have found other information on another forum:
Just go to "Piping and fluid mechanical forum" and tape: "Piping classes origin", you will find an interesting discussion...
See you!

RE: Piping classes
why spend the extra money installing pipe that can never be utilized fully. Same is true especially with 304SS, no need in sch40 when sch10 will work.
