A schedule number indicates the approximate value of theexpression1000 P/S, where P is the service pressure and S is the allowable stress,both expressed in pounds per square inch (psi). The higher the schedule number,the thicker the pipe is. The outside diameter of each pipe size is standardized.Therefore, a particular nominal pipe size will have a different inside diameterdepending upon the schedule number specified.
