Helical Hardbanding
Abstract
A tubular component (e.g., a drill pipe, work string pipe, etc.) with one or more hardbanding treatments on an external surface of the tubular component. One or more or all of the hardbanding treatments have a helical or spiral shape. The hardbanding treatment provides 1) enhanced durability to the central region of the tubular component at potentially lower costs, 2) enhanced strength and/or rigidity of the central region of the tubular component to reduce the amount of bending or flexing of the tubular component during the insertion and/or removal of the tubular component into/from a wellbore, and/or 3) improved fluid and debris flow about the central region of the tubular component.
