Component composition
The tubing coupling structure is that the tubing end and the inner wall of the coupling body are connected by tapered thread, and the end of the coupling body and the tubing are connected by the same thread and the same pitch horizontal thread.
Equipment characteristics
The utility model has the characteristics of alleviating the stress concentration at the root of the outer thread of a single conical thread connecting tubing, and is not easy to produce fatigue fracture, and has good connection effect. Effective prevention of tubing string break-off accident.
