Latest Patents
Leonard S. Landriault holds a patent for a new and improved threaded connector. This invention features one or more non-tapered threads on separate diametral steps, with at least one flank 'hooked' to achieve a tensile strength comparable to that of the tubular body. The design controls the wall thickness of the female member to enhance thread loading and allow inward radial movement with the male member, preventing 'pulling out' under axial tensile loading. The outer thread step on the male member may only partially engage the threads on the female member, minimizing the critical reduction of the tube wall thickness at the thread roots. This results in a threaded connection that boasts a tensile efficiency exceeding the tube body yield strength and approaching the ultimate tensile strength of the tube body.
