HOW
TO USE YOUR
EASY TAPPER MODEL #XTC-1.7S
TAPPING MACHINE
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-1.7S is 1,470 P.S.I.G. at 100 degrees F.
2. A Tapping saddle of proper size can 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-1.7S Hot Tapping Machine ships ready to use, by
first installing 2 strips of pure graphite packing under the
packing nut at the back of the machine front. Install the
second strip with the joining seam on the opposite side from
the first strip, to create a better seal. Grease has been
factory installed in the bearing box, and an o-ring seal for
the drive shaft has also been factory installed. 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. To add packing, loosen
the packing nut and install as listed at the beginning of
section 5 (above).
6. Now select the proper cutter, arbor and pilot bit, assemble,
and install the hexagon arbor shank into the hexagon receiver
(coupler), on the forward end of the drive shaft.
Note: refer to the cutter information on the back side of
these operating instructions for cutter size and recommended
cutting RPMs. The end of the pilot bit should be positioned
to penetrate the wall thickness of the main line before the
cutter teeth engage the wall of the main line. When using
the Easy Tapper coupon retaining pilot bit,
the spring-steel wire should pass through the wall of the
main line before the cutter teeth begin cutting. The cutter
and the pilot should now be tightened securely to the drive
shaft.
7. At this point it is a good idea to verify that the cutter
will slip through the branch line "full port" ball
valve unrestricted.
Stainless
Steel Tapping Procedures

Use a 1/4"
Cobalt Pilot Bit.
Position within the Bimetal Hole Saw to
extend completely through the wall of the pipe before the
teeth of the hole saw contact the wall of the pipe.
As the Cobalt
Pilot Bit penetrates the wall of the main line, fluid will
rush into the tapping machine body and will act as a coolant
for the Bimetal Hole Saw.
