Abstract
A core sampling and tapping assembly is disclosed that may be mounted to a cylindrical pipe. The assembly includes a nozzle having an interior portion extending between an open distal end and a proximal end. The proximal end sealed to an upper saddle member and the upper saddle member coupled to a lower saddle member to clamp the pipe in between. The assembly further includes a tapping mandrel including a mandrel plate, the tapping mandrel extending through the interior portion and a core cutter fixedly coupled to the mandrel plate. The assembly further includes a pilot bit coupled to the mandrel plate and disposed within an interior cavity of the core cutter. The tapping mandrel adjacently aligns the core cutter and the pilot bit with an outer surface of the pipe and subsequently rotates the pilot bit and core cutter to collect a core sample from the pipe.
