ABSTRACT:
Pipe tapping apparatuses, devices, methods, and systems are provided for hot-tapping a pipe or fluid conduit containing a pressurized fluid. According to an embodiment, a pipe-tapping device can comprise a machine lower portion, a machine feed portion, and a machine drive portion. The machine lower portion can be disposed proximate to a pipe and can include a threaded insert situated distal to the pipe. The machine feed portion can include a first thread set and a second thread set. The first thread set can correspond to the threaded insert so that the machine feed portion is adapted to move axially relative to the machine lower portion. The machine drive portion can include a threaded interior. The threaded interior can correspond to the second thread set so that the machine drive portion is adapted to move axially relative to the machine feed portion. Other various embodiments are also claimed and described.
