Abstract
A high-torque connection refacing tool, including a shaft, a mandrel, a primary face plate, and a torque-stop face plate.
Claims20
A high-torque pipe pin-end connection refacing tool, comprising:
- a shaft having a first end and a second end;
- a barrel attached to the shaft such that the first end of the shaft is disposed at least partially within the barrel;
- a primary face refacing plate attached to a rim of the barrel;
- a torque-stop refacing plate attached to the first end of the shaft;
- and
- a mandrel located in between the shaft and the barrel.
3 more elements
A refacing tool for refacing torque-stop and primary faces of a pin-end of a pipe, the refacing tool comprising:
- a mandrel having internal threads configured to screw onto external threads of the pin-end of the pipe;
- a barrel slidably and rotatably fitted over the mandrel, the barrel comprising a distal rim;
- a primary face refacing plate connected to or integrated with the distal rim of the barrel;
- a driving shaft coupled to the barrel, the driving shaft being rotatably and slidably secured at least partially within the mandrel;
- and
- a torque-stop refacing plate connected to the driving shaft and positioned within the mandrel.
3 more elements
A refacing tool for refacing torque-stop and primary faces of a pin-end of a pipe, the refacing tool comprising:
- a barrel rotatable by a drive mechanism;
- a primary face refacing plate connected to or integrated with a distal end of the barrel for refacing a primary face of a pin-end of a pipe;
- a mandrel disposed within the barrel, such that the barrel can rotate and slide relative to the mandrel, the mandrel comprising internal threads configured to screw onto external threads of the pin-end of the pipe;
- and
- a torque-stop refacing plate linked to the barrel such that the torque-stop refacing plate rotates with the barrel, the torque-stop refacing plate being positioned within the mandrel at a fixed distance from the primary face refacing plate.
