  • ANSI Taper Pipe Threads | Thread Gauges Limit Gauges
    Gauges for taper pipe threads NPTF are used to check the dimension of such the threads There are many types of gauges for taper threads with various different notches In general the gauges for taper threads L1 having three notches i e minimum limit position ① basic position B and maximum limit position ② are the most commonly used The use of the taper thread gauges has been explained in the previous pages However since there is a specifi cation of truncation for major and minor diameters of thread height it is recommended to measure major and minor diameters using plain taper gauges having 6 step notches First the pitch diameter of the taper thread is measured with a taper thread gauge For example when it is judged pass at near the notch of basic position B then for major and minor diameters is also similar That is the item is judged pass when the pipes can go within limit range of B For inspection of tight tolerances taper thread plug L3 and taper thread ring L2 are used Refer to the following page of NPTF type threads for the detail methods of inspection There are many types of taper
