The threaded connection is the weakest link, and more than 80% of failures occur at the threaded connection. oil well pipe threads should mainly have two characteristics: (1) structural integrity, that is, the threads should have sufficient connection strength after meshing so as not to damage the structure under the action of external forces; (2) sealing integrity, which is required It can ensure that the pipe string containing hundreds of threaded connection joints can withstand the long-term action of the internal and external pressure difference (generally several hundred atmospheres) under various stress conditions without leaking. Thread connection strength and sealing performance are two extremely important technical indicators of oil well pipes.
