Hello Experts
I am designing a fitting which is 1/8" nps size.
I used the formula for calculation: Sch=1000P/S
Working pressure is 2000 psi and allowable stress is 13,300psi.
I got 150sch (i used 160sch# based on table 2).
But when i checked the dimensions in table 5, class 2000 and 3000 are the same.
Please explain to me the difference between these two classes.
Thank you for your answers.
