The following guidelines are intend

The following guidelines are intended to provide the fabricator and installer a basic interpretation of ANSI B1.20.1 National Pipe Tapered Thread (NPT), SAE AS71051B Aeronautical National Pipe Tapered Thread (ANPT) and their respective gaging specifications so to quickly determine whether the pipe nipple is cut and/or the joint made-up properly. Both NPT and ANPT taper pipe threads have the same general form and dimensions except ANPT tolerances are held a bit closer. There are many variables that effect thread quality and form from dull or improperly ground chasers to incorrect machine set-up and performance, these guidelines are to be used in conjunction with the referenced specifications, periodic quality control inspection measures and experience. Furthermore these recommendations assume the threads are properly formed i.e. free from chatter & tares and are not out-of-round.
