Abstract:
A pipe doping apparatus comprises a bucket assembly including a base and a bucket supported on the base and having an inside volume, a lubricating unit having at least one lubricant applicator inside the bucket; and a source of torque configured to rotate the bucket and/or the lubricating unit relative to a tubular. The apparatus may include a cleaning unit and/or a drying unit and the source of torque may be a fluid jet in either. At least one lubricant applicator may be retractable and may be actuated between a retracted position and an extended position by centripetal force. The apparatus may further include a positioning assembly supporting the base and the rotary bucket assembly and a controller connected to and controlling each of:—the positioning assembly, the cleaning unit, the drying unit, and the lubricating unit.
