RE: quesion about schedule
P-service pressure PSI
S-allowable stress PSI
The outside dia. of each pipe size is standardized, thus, a particular NPS will have a different inside dia. depends upon the sch. number specified.
Sch. STD: the nominal wall thick. of NPS 10" and smaller is same as Sch. 40
Sch. XS: the nominal wall thick. of NPS 8" and smaller is same as Sch. 80
Sch. numbers followed by the letter S (B36.19M) are primarily intended for use with stainless steel pipes. The wall thickness may not be the same as that specified without the letter S.
