Once, I worked with Givens International and we sold some drill pipe to a good customer in Turkey. The pipe would go on a new Driltech rig that our customer had sold for a water well application. But we got back reports of thread problems. I had to go to Turkey to check it out.
Of all pipe issues, thread damage is the most difficult to diagnose. Taking measurements of a damaged connection — if that is all you have — likely won’t help determine if was manufactured correctly. How the damage looks and where it is on the connection can give us some hints. Also, the timeframe: Did this occur on the first trip downhole, the second or after a few months?
