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.
We are making efforts to develop fine processing of our Stainless Steel Tube Fittings Coupling Grooved Pipe for 3 Way and establish a diversified industrial structure. Our company is based on good faith, we do everything for users, your requirements are our goal and your satisfaction is our wish. We insist on relying on our employees, training them, and making them successful, so as to achieve the common progress of the company and its employees.
