National Standard Taper Pipe (NPT) Threads Size Chart. Nominal size (inside diameter) Actual OD. Threads per inch. Length of engagement (tightened by hand) Hand tight turns.
National Standard Taper Pipe Threads Size NPT Chart - Includes both External and internal Pipe Thread Data. The taper rate for all NPT threads is 1⁄16 (3⁄4 inch per foot) measured by the change of diameter (of the pipe thread) over distance.
NPT series – Tapered Pipe Thread. NPT stands for National Pipe Tapered threads. The basic profile is a 60° truncated triangle similar to the Unified Inch threads (UNC/UNF). The main difference is that the thread profile is tapered at an angle of 1°47′ (0.75 in/ft or 62.5 mm/m) relative to the axis.
4 lis 2012 · The outside diameter of a pipe or fitting must be measured and compared to a table for size identification. A 3/4" NPT pipe thread has an outside diameter - OD - of 1.050 inches. Each thread size has a defined number of threads per inch - TPI, or pitch. The 3/4" NPT pipe thread has 14 threads per inch.
The best way is to do this over a space of 5 crests, and divide the result by 4 (why 4? Because you are dividing by the number of roots between the crests). The resulting number is the pitch of the given thread. Compare it with the chart and see which NPT thread you need!
