  • Patent number: 9334706
    Abstract: The present invention relates generally to a Top Drive Pipe Spinner (TDPS). The TDPS is a tool that allows for the setting of casing without a specialized crew or any additional power source. By employing the weight of the existing top drive to set slips on the casing collar, the TDPS allows one casing to be threaded onto the next in a timely and efficient manner. The casing tongs of the TDPS use passive release weight to release the casing collar from the casing to allow for the successive insertion of another casing section. The top drive spins the TDPS and compresses the unit onto the casing, then lifts the unit and releases the casing when desired.
