Nano-coating high-strength anti-thread-gluing anti-eccentric-wear special threaded oil pipe

The invention relates to the field of oil pipes, and discloses a nano-coating high-strength anti-thread-gluing anti-eccentric-wear special threaded oil pipe which comprises an oil pipe body and an oil pipe coupling which are assembled together, API threads are adopted as threads of the oil pipe coupling, the oil pipe body is divided into a flat oil pipe body and an external upset oil pipe body, ZB-JTAS threads are adopted at one end of the oil pipe coupling, and API threads are adopted at the other end of the oil pipe coupling. ZB-JTAS threads are adopted at the two ends of the tubing coupling, a torque shoulder is integrally formed on the inner wall, the inner wall face of a tubing is flush with the inner wall of the torque shoulder, the torque shoulder is additionally arranged and makes contact with the end of the tubing, contact pressure is generated, the sealing effect is achieved, the turbulent flow phenomenon of gas or liquid in a pipeline is effectively reduced, and the sealing performance of the tubin
