I assume you are using an optical reticle for inspection of the part. Obviously the higher the magnification the higher the accuracy of the measurement. You want to invest in a calibration block to verify your measuring accuracy. Northern Gauge Sherwood Park Ab
Keep in mind that there are different types of NPT gauges that gauge different characteristics of the thread. The NPT L1 plug checks for hand tight engagement and will not check the thread taper. In order to check the taper one must also purchase either a NPT L3 plug which checks wrench tight...
Is there some exception in ASME regarding not having to perform PWHT on minor surface weld repairs (i.e. porosity of RTJ surface), eventhough the WPS has been qualified with PWHT. Northern Gauge Sherwood Park Ab
Hello, gauge dimensions for coated part threads are based on gauge maker tolerances along with the coating thickness of the part. I carry a line of thread gauging call Northern Gauge in Canada; perhaps I can help supply you a gauge for your specific application.
