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 aim at marketization and industrialization, uphold the basic model of integrated R&D and collaborative innovation, and focus on new development of Cardan Shaft Driving Universal Coupling SWC225A-800 Used for Steel Tube Mill, key technology breakthroughs and application development. The prosperity of brand leads to the prosperity of enterprise, and the decline of brand leads to the decline of enterprise. We insist on broadening our horizons, broadening our research fields, so that we can obtain new ideas and achievements.
