You can see the pipe schedule calculation formula as below; Schedule number = P/S. P is the service pressure in (psi) S is the allowable stress in (psi) So, what does schedule 40 means? Schedule 40 is nothing but a pipe thickness designator. In simple word you can say that for a given material, schedule 40 pipe can withstand a certain amount of pressure. Allowable Working Pressures (Type 304L)Main Pipe Menu Allowable Working Pressure (304L) Allowable Working Pressures (Type 304L) The allowable stress values used are shown in table A-3 of the ASME Code for Pressure Piping B31.1 1989 Edition for welded pipe to SA-312 with a weld joint efficiency of 0.85.

Notes:1) Shaded areas indicate tubing that is not suitable for gas service. 2) For welded and drawn tubing, a derating factor must be utilized. For double welded tube, multiply the below pressure rating by 0.85; and for single welded tube by .80 (ANSI B 31, Table A-1B).

The allowable pressure for a 4 inch schedule 40 pipe at temperature 100oF and allowable stress 20000 psi can be calculated as. P = 2 (20000 psi) ( (1 - 0.125) (0.237 in) - (0 in)) / ( (4.5 in) - 2 (0.4) ((1 - 0.125) (0.237 in) - (0 in))) = 1914 psi.
