Hi, first thanks for reply mi post, second you don’t misunderstand my post… We have been using # for pipes but then I try to look for the thickness os a pipe based on ASME ANSI and API and trying… then I wasn’t able to mach # with and schedule, I can follow for fitting set a pressure and then look for a schedule…
But that is why im not sure that it is correct if I say 6” 150# there is no and schedule ore thinness specificated, and as far as I see is no correct if you are using those specifications…

But I’m asking because im not sure, if im wrong please write the steps using the specifications for matching a # pipe whit and schedule.

Sorry for my English…
