  • Pipeline internal field joint cleaning, coating, and inspection robot
    Patent number: 8800396
    Abstract: There is provided herein an electrical robotic system for locating, cleaning, and repairing holidays within coated pipe that are proximate to a girth weld. In a preferred arrangement, a robotic train will be placed in the pipeline that will perform the functions of holiday location, cleaning/preparation of the surface containing the holiday, and repair thereof, in a single run through the pipeline.
    Type: Grant
    Filed: July 14, 2011
    Date of Patent: August 12, 2014
    Assignee: CRTS, Inc.
    Inventors: Russell Langley, James A. Huggins, John D. Carter, David Paulley, Keith R. Roberts, Darrell L. Davis, Michael E. O'Neill, Steve D. Hayes, Dale G. Davis, John D. Lindemann
  • Internal pipe coating inspection robot
    Patent number: 8633713
    Abstract: There is provided herein a robot-based electrical system for locating holidays within coated pipe that does not utilize a grounding wire. In a preferred arrangement, the robot will carry a metal rotating brush/capacitive pad combination and changes in the capacitance in the brush/pad circuit will be used to identify imperfections in the interior coating of the pipe and especially those located proximate a girth weld. In another preferred embodiment, a circumferential brush will be used that allows testing of the integrity of the internal coating throughout the length of the pipe as the robot travels the pipeline.
