Abstract
A pipe assembly may have one or more pipe segments that are coupled together or coupled to a drive socket by a coupler. The coupler may have a body with a generally tubular shape with an interior surface and an exterior surface. First and second flanges may extend outward from the exterior surface to engage the drive socket, thereby providing enhanced stability and coaxiality. The interior surface may have an upper receiving feature that can receive the bottom end of an overhead pipe segment, and a lower receiving feature that can receive the top end of a subtending pipe segment. The upper receiving feature may have an upper threaded bore with a lead-in portion that facilitates alignment of the overhead pipe segment with the upper threaded bore. The interior surface may also have a stop feature that prevents over-insertion of the top end and/or the bottom end into the coupler.
