Description

Ojiyas Gauges for ANSI Taper Pipe Threads

Gauges for ANSI taper pipe threads are used to inspect general sealable parts. Various gauge specifications are used, some of which have notches. Common thread plug and ring gauges have 3 step notches (L1). If the inspected taper thread conforms to the standard dimensions, the pipe end stops at the middle notch on the gauge. The other two notches are there to indicate the maximimum and minimum allowed dimensions.

NPT National Pipe Taper

Taper pipe threads (NPT) specified in American standard (ANSI) are used to connect pipes, plumbing parts, fluid equipments and etc. Their purpose is to increase the density resistance of the threaded parts. Ojiyas Gauges for taper pipe threads (NPT) are used for measuring dimension of such threads.

NPTF National Pipe Taper Fuel and Oil

Taper pipe threads NPTF specified in American standard (ANSI) are meant for threads used to join ful or oil pipes in ships, automobiles, aircrafts and etc. These threads are designed to achieve dry seal joints without a sealing material. In NPTF threads, the density resistance of the thread parts can be obtained even without using seal compound. L1 plug and L1 ring are used to check the wrench-tight length (L3 and L2-L1) of external and internal threads. When the position of the notches of the two gauges, L1 and L3 plug, or L1 and L2 ring, tightens, it is not more than half a turn. The product’s degree of taper is also guaranteed.
