1) STD (standard) = schedule 40

2) XS (extra strong) = schedule 80

The calculations of allowable pressure in the table above are made with the ANSI/ASME Piping Code B31.1 equation:

P = 2 SE (tm - A) / (Do - 2 y (tm - A))                        (1)

where

P = allowable pressure (psi)

SE = maximum allowable stress in pipe wall (psi)

tm = wall thickness (in)

A = additional thickness depending of type of pipe (in) (A = 0 for the calculations above)

y = a coefficient depending on material and temperature range (y = 0.4 for the calculations above)

Do = outside diameter (in)
