What is the difference between NPS and NPT?

NPT (National Pipe Thread) and NPS (National Pipe Straight) have the same thread angle, shape, and pitch (threads per inch). However, NPT threads are tapered and NPS threads are straight (parallel). Both threads have a 60° included angle and have flat peaks and valleys.

How is pipe NPS calculated?

by the pipe NPS minus double the pipe wall thickness (which can be obtained from the pipe schedule). For example, for a 12 NPS (DN 300 mm) pipe, schedule 40, the OD and wall thickness are respectively 12.75 inches (324 mm) and 0.406 inches (10.4 mm). Thus: Pipe ID = 12.75 inches – 2 x 0.406 inches = 11.94 inches, or.
