United States Steel has achieved a significant milestone with the recent granting of a patent (Publication Number: US11965611B2) for an innovative threaded pipe connection design. This breakthrough technology is designed to enhance the structural integrity and stress distribution of tubular components, particularly pipes, by utilizing wedge-shaped threads with varying widths and taper angles.
The patented design involves a first tubular component with pin threads and a second tubular component with box threads. These threads are meticulously engineered with specific width and taper angles to create a bias that concentrates stress on certain flanks. This configuration ensures that the stress decreases along the connection, thereby promoting durability and reducing the risk of failure. Additionally, the design is structured to engage the threads in a controlled manner during rotation, optimizing the connection process and enhancing reliability.
The threaded connection design also includes various adaptations to further improve its performance. For instance, the design can incorporate different taper angles between the pin and box threads, root width rate variances, and specific configurations to prevent the trapping of thread compounds. These features collectively contribute to a more robust and versatile connection, suitable for a wide range of applications in industries that rely on tubular components.
The novel threaded connection design is also adaptable for metal-to-metal sealing members, enhancing its versatility and potential applications. This adaptability is particularly important in industries such as oil and gas, where reliable and durable pipe connections are critical for safe and efficient operations. The metal-to-metal seal provides an additional layer of protection against leaks and enhances the overall integrity of the connection.
The benefits of this patented technology extend beyond improved performance and reliability. By ensuring controlled engagement during rotation and optimizing stress distribution, the design reduces the likelihood of wear and tear on the threads, thereby extending the service life of the tubular components. This not only leads to cost savings in terms of reduced maintenance and replacement but also contributes to the sustainability goals of industries by minimizing material wastage.
