J55 Tubing Coupling
The J55 tubing coupling is a critical component in drilling tools, primarily used for connecting tubing pipes. It addresses the issue of fatigue and fractures in conventional couplings caused by stress concentration.
Structural Design:
The tubing end connects to the inner wall of the coupling body via tapered threads.
The end of the coupling body connects to the tubing pipe using flat threads with the same thread type and pitch.
Technical Advantages:
Reduces stress concentration at the root of the external threads, minimizing fatigue fractures.
Ensures excellent connection performance, effectively preventing tubing string detachment accidents in oil wells.
Anti-Corrosion Design:
The coupling is designed with anti-corrosion features, protecting the threaded sections of the coupling and connected pipes.
Provides strong sealing at the connection points between the coupling and tubing threads.
Undergoes anti-corrosion treatment on both inner and outer surfaces of the coupling.
