Ensuring API tubing thread connection sealing performance Based on many years of experience in tubing thread processing and quality control, re-grinding and installation of tubing thread combs, taper errors, pitch errors, profile errors, and quality testing of tubing threads Control measures to ensure the sealing performance of API tubing threaded connections. The advantages and disadvantages and the tooth profile errors of the tubing threads that are directly roughed and finished with a combing tool or rough and combed with an ordinary thread turning tool are analyzed in detail. Rough, then fine with a comb. It is recommended that the manufacturing tolerances for the height of the top and bottom of the tubing thread comb comb be increased from ± 0.02mm to ± 0.01mm, and the cumulative pitch tolerance of the tubing thread be controlled within the range of ± 0.02mm to improve the API tubing thread connection. Sealing performance.
