NPSM Thread Gauge for Straight Pipe thread Couplings OD 10"
NPSM thread gauge is a kind of American Standard Straight Pipe Threads for free-Fitting Mechanical Joints for Fixtures.NPSM thread belongs to the cylindrical pipe thread used for mechanical connections.There are NPSM Ring go/no go Gauge,NPSM Plug go/no go Gauge.
NPS thread belongs to the American standard cylindrical pipe thread with the standard number ANSI B2.1.The standard number is ANSI B1.20.1 NPSC thread, which belongs to the cylindrical internal thread used in American pipe fittings. Its standard number is also ANSI B1.20.1. Visible NPS, NPSM and NPSC are three different types of threads, and attention should be paid to their differences when using them, especially when NPS and NPSM threads are known to be two different types of threads.Do not mix and use in threaded pairs to prevent abnormal fit.The three diameters of American 60 standard pipe threads cannot be calculated using simple formulas, so it is necessary to find the corresponding standard for reference when needed.
