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.
The company has a good heritage, strives to innovate, and fully considers the market needs of Durable Industrial Tube Connector Stainless Steel Equal Straight Coupling thoughout its many years of business. Green industry implies the synergistic development and harmonious progress of human and natural environment. We adhere to the development concept of scientific and technological innovation, and vigorously promote technological research and development and technological innovation.
