Special threaded joints are relatively API joints. API threads are widely used worldwide, but their tightness cannot meet the needs of oil fields, especially in terms of air tightness and tensile strength. Therefore, the research and development of VAM series threads (VAM, VAM-Top, New-VAM), CS, PH6, FOX, FJL, BLUE and other series threads have been obtained in terms of high link strength, high sealing, anti-stick threads, and stress corrosion resistance Great improvement. Despite its high maintenance cost, it is widely used in oil wells
