What Is an NTP Gauge and Where Is It Used?
An NTP Gauge, commonly associated with NPT (National Pipe Taper) thread gauging, is a precision inspection tool used to verify tapered pipe threads. NPT thread gauging is covered by ASME B1.20.1, which addresses dimensions and gaging requirements for NPT and related pipe-thread forms.
Our NPT Thread Gauge range supports inspection of internal and external tapered threads through plug and ring configurations. These gauges are particularly relevant to valves, fittings, pipes, hydraulic assemblies, oilfield equipment, and pressure-related components manufactured or inspected around Cikarang and Bekasi, as well as industrial manufacturing clusters in Karawang, Batam, Surabaya, and Gresik.
Working Principle of NTP Gauge
- Controlled Thread Engagement — Accurate inspection depends on controlled engagement between the gauge thread and the component thread.
- NPT Thread Plug Gauge — An NPT Thread Plug Gauge verifies the dimensional accuracy and acceptance of internal tapered threads.
- NPT Thread Ring Gauge — An NPT Thread Ring Gauge checks external tapered threads to confirm proper thread conformity.
- 1:16 Taper Geometry — The critical 1:16 diameter taper of NPT threads requires precise engagement and specialized inspection methods.
- Digital Inspection & Traceability — Modern NTP gauge inspection combines precision machining, optical verification, digital measurement records, and controlled calibration for traceable results.
