1. Pay attention to avoid holding any part of the drill pipe body with a vise, so as to avoid the rod body being pinched by slips, and the Luohe drill pipe will reduce the service life of the drill pipe. Use qualified zinc-based rib grease, butter is not suitable for use as thread oil.
2. Insufficient thread grease will damage the shoulder of the joint and produce high points, and the oil drill pipe will easily "loose" the threaded connection and cause the thread to be damaged. Do not use thread grease or use unqualified thread grease, the surface of the thread will be glued, resulting in the phenomenon of sticking.
