  • Pipe pig
    Patent number: 10895341
    Abstract: A pipe pig is provided with linked wheels, and at least a central wheel of the linked wheels is pivotally linked to adjacent wheels through a spring loaded connection that biases the central wheel out of straight line alignment with the adjacent wheels. The pipe pig may be used to negotiate tight bends in a pipe and carry sensing electronics.
    Type: Grant
    Filed: August 21, 2018
    Date of Patent: January 19, 2021
    Inventor: Orlande Wayne Sivacoe

  • Pig pumping unit and method
    Patent number: 9573173
    Abstract: A pumping unit is provided that controls fluid pressure in a pipe being traversed according to the degree of resistance encountered by a pig traversing the pipe under fluid pressure. Increasing fluid pressure in constricted areas enables an intelligent pig to traverse the pipe with a more uniform speed by controlling the fluid velocity.
