Operating Instructions
Planning The Tapping Operation
WARNING
Cutting into pipe containing liquids
or gases under pressure is potentially hazardous.
Correct procedures must be followed in the use of
this equipment. Only trained personnel should use
this tapping tool.
To prevent extensive property damage and/or se-
rious injury, proper planning of the tapping
operation is required. The following procedure
should be followed every time the tapping tool is
used.
1. DETERMINE EXACTLY WHICH PIPE NEEDS TO
BE TAPPED INTO. Follow the pipe as far as possible
to ensure it is the pipe that requires tapping. Record
the media and the pressure on a copy of the work-
sheet, Appendix II, at the back of this manual.
WARNING
Do not exceed pressure and tem-
perature ratings of the tool and any attachment, valve
or fitting. Only tap into lines that contain water, air,
steam or natural gas.
Water: 200 psig @ 100ºF (40ºC)
Air, Steam, Natural Gas: 100 psig @ 370ºF (172ºC)

2. DETERMINE EXACTLY WHERE THE PIPE NEEDS
TO BE TAPPED. Consider not only the best route for
the new line but also the effect that any chips from the
tapping operation could have on downstream equip-
ment. Consider the orientation of the tap, tapping
the top of the pipe may drop chips into the tapped
pipe whereas tapping the bottom of the pipe will tend
to drop the chips back into the tool.
3. DETERMINE WHETHER A SERVICE SADDLE OR
A WELD-IN-PLACE THREAD-O-LET™ OR WELD-
O-LET™ WILL BE USED TO MOUNT THE VALVE
TO THE MAIN. Consider the advantages and disad-
vantages of each type. Record this connection data
on the worksheet.
NOTE! The "Thread-O-Let™" or "Weld-O-Let™" may
only be welded to compatible metal pipe.
Although Thread-O-Lets may have a pressure
rating, the strength of the weld to the pipe is vir-
tually impossible to certify without x-rays. The
media in the pipe may also adversely affect
weld penetration due to chilling. In addition,
weld may penetrate far enough into the pipe
to allow the pressure in the pipe to blow through
the molten weld puddle.
A service saddle may be used on any type of
pipe that has a compatible outside diameter.
Insure the saddle pressure rating is equal to
or greater than the pipe system.
4. SELECT WHICH "CORPORATION STOP" OR
VALVE IS TO BE USED. Only a full port ball, plug or
safety valve will work. The valve must meet following
criteria:
• Must have an adequate pressure rating.
• Made of material compatible with the media.
• Must allow the cutter to pass through the valve.
This should be checked prior to mounting the valve.
NOTE! A corporation stop is a valve with a square lug
for a wrench instead of a handwheel to open
and close the valve. This is to ensure that the
valve is not operated inadvertently or by unau-
thorized personnel. Typically, corporation stops
have male NPT inlet threads that screw directly
into a service saddle or "Thread-O-Let" with-
out the need for an intermediate "close nipple"
as an adapter.
