Latest Patents

Yohinori Ando holds a patent for a high-torque threaded connection specifically designed for steel pipes. This invention features male and female threadforms constituted by wedge threads, which provide high shear resistance and high torque resistance. The design includes a radius of curvature at the base of the load flank of the first thread, ensuring it is not lower than the thread height multiplied by 0.14, and preferably not lower than 0.16. This improvement significantly enhances the shear resistance of the first thread. Additionally, the thread pitch can be reduced to increase the number of threads, thereby increasing the area of contact for load flanks. This innovative approach maintains high torque resistance while optimizing the design for better performance.
