HOW
TO USE YOUR 1. Verify the source, destination, type, contents, and pressure of the line you are about to tap. Note: Maximum tapping pressure for the Model XTC is 600 P.S.I.G. at 100 degrees F. 2. A Tapping saddle of proper size can then be tightened on to the main line. (In some cases a thread-o-let or malleable iron nipple can be arc welded to the main line). 3. A short nipple is then threaded into the tapping saddle. 4. A "full port" ball valve is then threaded onto the short nipple. Note: Gate valves are not recommended in this case, because shavings from the drilling process tend to collect in the gate chamber, preventing the gate from closing all the way. 5. The XTC 1 Hot Tapping Machine ships ready to use, 2 strips of 100% pure graphite will need to be installed under the packing nut, around drive shaft at the back end of the machine. Install so the packing seams are on opposite sides. Then packing is installed as needed. Additional packing can be added at any time (even during the tapping process, simply by withdrawing the drive shaft and cutter back out of the branch line valve and then closing the branch line valve while packing is installed). Packing strips are pre-cut to fit properly. 6. Now select
the proper cutter and install the hexagon arbor of the cutter into
the hexagon receiver end of the drive shaft. Note: the proper cutter
size will generally be 1/8” smaller than the "full port"
size of the branch line ball valve you are tapping through. The
pilot bit can now be installed in the arbor to lead the cutter.
The end of the pilot bit should be positioned to penetrate the wall
thickness of the main line before the cutter engages the wall of
the main line. The cutter and the pilot should now be tightened
securely to the drive shaft.
