Wrought Steel Pipes - Bursting Pressures vs. Size
Theoretical bursting and working pressure of wrought steel standard, extra strong and double extra strong pipes.
The bursting pressures are based on Barlow's formula. The working pressures are based on factor 8.
Dimensions according ASME/ANSI B36.10/19.
