Why dont TopTorq threads wear like other tapered threads?
Most tapered pipe threads connections require two to six power turns to either make or break, which causes wear and tangential stress between the box and pin threads particularly, when they are over-tightened, which casts doubt as to whether they can be safely inspected or used again, because the pin end may be yielded. Conversely, makeup of a TopTorq connection requires less than one power turn, with no fear of over-tightening. Therefore, thread burning and galling does not occur, so phosphate can serve in place of plating.
