Title: Frank J Carlin: Innovator in Drill Pipe Technology

Introduction

Frank J Carlin is a notable inventor based in Houston, TX (US), recognized for his contributions to the field of drill pipe technology. With a total of 9 patents to his name, Carlin has made significant advancements that enhance the efficiency and safety of drilling operations.

Latest Patents

One of Carlin's latest patents is the Drill Collar Box. This innovative design addresses the connection stresses encountered during drilling and the makeup of the connection. The thread root design in the box reduces fatigue damage caused by makeup torque and cyclic stressing of the engaged drill string connection as it rotates around curved sections of the well bore. The conventional V-type thread form in the box features an enlarged root radius, which is offset from the centerline of the opposing thread flanks. This design allows the load flank of the thread to tangentially engage the arc of the root, while the stab flank intersects with the enlarged root radius extending to a flat intersecting surface.

Another significant patent is the Discontinuous Plane Weld Apparatus and Method for Enhancing Fatigue and Load Properties. This apparatus and method improve the fatigue and load properties of subterranean well drill pipe at the securement area of pipe sections. By providing a weld in a discontinuous plane, the design secures pipe sections to each other with a greater cross-section of welded surface. This innovation is less prone to failure due to rotational, tensile, and bending stresses, as well as heavy loads arising from shock loading.
