Pipe tapping apparatuses and systems
View Patent ↗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.
1. A pipe-tapping apparatus comprising:
a machine lower portion adapted to be disposed proximate a pipe and comprising a threaded insert;
a machine feed portion comprising a first thread set and a second thread set, the first thread set corresponding to the threaded insert so that the machine feed portion is adapted to move axially relative to the machine lower portion; and
a machine drive portion comprising a threaded interior, the threaded interior corresponding to the second thread set so that the machine drive portion is adapted to move axially relative to the machine feed portion,
wherein the machine drive portion comprises a locking member to engage the second thread set so that the machine drive portion is inhibited from moving axially relative to the machine feed portion.
2. The apparatus of claim 1 , wherein the first thread set and the second thread set have different thread pitches so that the machine feed portion and the machine drive portion have different axial movement rates.
3. The apparatus of claim 1 , wherein the machine lower portion comprises means interacting with the first thread set so that machine feed portion is inhibited from moving axially relative to the machine lower portion.
4. The apparatus of claim 1 , further comprising at least one handle member adapted to provide rotational energy to the machine drive portion in a first operational mode and to the machine feed portion in a second operational mode.
5. The apparatus of claim 1 , wherein the second thread set has a higher thread pitch than the first thread set.
6. The apparatus of claim 1 , wherein the machine lower portion comprises an engaging member to engage the first thread set so that machine feed portion is inhibited from moving axially relative to the machine lower portion.
7. A pipe-tapping method comprising:
providing a pipe-tapping device proximate a pipe, the pipe-tapping device comprising a first thread set and a second thread set with different thread pitches so that the first thread set and second thread set provide different axial movement rates;
selectively engaging one of the first thread set and the second thread set to enable positioning of the pipe-tapping tool in a second operational mode and tapping of the pipe in a first operational mode;
positioning the pipe-tapping tool proximate to an outer surface of the pipe with the first thread set, the pipe-tapping tool being adapted to be removably secured to the pipe-tapping device; and
tapping the outer surface of the pipe using the pipe-tapping tool in communication with the second thread set.
8. A pipe-tapping method comprising:
providing a pipe-tapping device proximate a pipe, the pipe-tapping device comprising a first thread set and a second thread set with different thread pitches so that the first thread set and second thread set provide different axial movement rates;
selectively engaging one of the first thread set and the second thread set to enable positioning of the pipe-tapping tool in a second operational mode and tapping of the pipe in a first operational mode;
positioning the pipe-tapping tool proximate to an outer surface of the pipe with the first thread set, the pipe-tapping tool being adapted to be removably secured to the pipe-tapping device; and
tapping the outer surface of the pipe using the pipe-tapping tool in communication with the second thread set.
9. The method of claim 7 , further comprising attaching an operator to the pipe-tapping device, the operator operable to provide rotational energy to the pipe-tapping tool.
10. The method of claim 7 , wherein the second thread set has a higher pitch ratio relative to the first thread set.
11. A pipe tapping method comprising the steps of:
providing a pipe-tapping device proximate a pipe, the pipe-tapping device comprising a first thread set and a second thread set with different thread pitches so that the first thread set and second thread set provide different axial movement rates;
positioning a pipe-tapping tool proximate an outer surface of the pipe with the first thread set, the pipe-tapping tool being adapted to be removably secured to the pipe-tapping device;
engaging a locking mechanism to inhibited axial movement via the first thread set after positioning the pipe-tapping tool proximate to the outer surface of the pipe; and
tapping the outer surface of the pipe using the pipe-tapping tool in communication with the second thread set.
