This should be a little more definitive for you. Here's a tip for you. When calculating the working pressure of pipe almost everyone forgets to take into account the standard manufacturer's allowance on wall ie which is Therefore any calculation you derive should be multiplied by.

The schedule number on pipe products relates to the thickness of the wall on the pipe: as the number increases, the thicker the wall thickness becomes. Also, while the schedule number can be the same on different sized pipes, the actual wall thickness will be different.

Here are a few examples:. What we can see here is that the schedule number increases the wall size, and that the wall thickness changes based on the nominal pipe size NPS. The best way to see the relationship between pipe size, schedules and wall thicknesses is simply to refer to a conversion chart below :. The NPS size represents the approximate inside diameter not outside of the pipe; if the schedule number on a set size is changed, it does effect the inside diameter ID but not the outside diameter OD.
