Introduction
Steel Tube Coupling is a kind of drilling tool in oil field, which i$ mainly used for tubing connection. The tubing coupling mainly solves the problem of fatigue fracture of existing coupling due to stress concentration.

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.
Since we use standard assembly line production equipment, our Stainless Steel Threaded Socket Weld Tube Coupling is more formal, reliable in quality and inexpensive. We sincerely hope that we will continue to cooperate with the vast number of users and all walks of life in order to advance hand in hand and develop together from now on. We constantly update the production equipment, strengthen the professionalism of staff, enhance the competitiveness and differentiation of customer products, so that our service is more perfect and efficient.
