FromStandard Sets. Once you know your wire diameter, you need to find out what is the premissable Measurement for your pitch diameter (Depending on the class). Use our Over Wire Calculator to find out! 1/16-27 NPT : Basic Thread Dimensions (Pitch, minor & major diameters, depth, lead), Tolerance range for all applicable classes and much more.
Pipethreads are based on the size of schedule 40 black pipe which is measured by the inside diameter of the pipe. 1/2” schedule 40 pipe has a 1/2” hole through it. As pipe schedule changes, the outside diameter remains the same and the inside diameter shrinks for the same size pipe.NPTThread Sizes. The most frequently used sizes for NPT threads are 1/8, 1/4, 3/8, 1/2, 3/4, 1, 1+1/4, 1+1/2, 2, 2+1/2, 3, 4, 5, and 6 inches. These sizes can be commonly found on pipes and fittings in the United States. Occasionally, smaller sizes below 1/8 inch and larger sizes exceeding 6 inches are utilized for specific purposes.
