Schedule....

[cpasseno03]

Hi... Anyone know the actual definition of schedule thicknesses of pipes and such? We all know that sched. 40 PVC is about a 1/4" wall thickness, but how is that figured? Is it a certain percentage or ratio of the ID and OD? <br />Thanks again!<br />Craig<br />PS lately most of my internet searches for trivia like this have been answered right here! Thanks!
