ATI™ - Drillstring Thread Inspection
TSC’s ATI™ array probes cover a wide range of common drillstring connecton sizes. With appropriate adapters fitted this probe can be used to inspect a variety of pin and box threads and has been used successfully on NC38, NC 46, NC50, 4 ½ IF, 6 5/8 Reg, 7 5/8 Reg and HT40 connectors. Probes for other thread forms or pitches are also available. Integral stainless steel scrapers engage in the thread and closely follow the thread profle. The scrapers remove dirt and contaminants from the thread and prevent wear to the thread sensors which are held close to, but not in contact with, the thread.
