Weld the Mounting Hardware Onto
the Pipe
Threaded Flo-tap
Flanged Flo-tap
Tack Weld the Mounting Hardware
with 4 Equal Length Tacks

Tack weld anywhere on
the mounting hardware

Then again directly across
from the first tack weld

Then on the other 2 sides

Check to See that the Mounting
Hardware is Level and Square

If it’s not, use a
rubber mallet to
lightly adjust the
hardware and
recheck
Verify that the ODF Dimension
Matches What is Listed in the QIG
The ODF is the dimension from outside pipe
diameter to face of flange

Verify that the ODF Dimension
Matches What is Listed in the QIG
The ODF is the
dimension from
outside pipe diameter
to face of flange
For Threaded Flo-tap the dimension
from the pipe OD to the top of the
threadolet is called LMH:
485 Sensor Size 1: 1.38-in. (35 mm)
485 Sensor Size 2: 1.56-in. (40 mm)
485 Sensor Size 3: 2.06-in. (52 mm)
Complete a Continuous Weld Around
the Perimeter of the Unit
Attached the Full Port Valve to the
Mounting Hardware
Threaded Flo-tap
Flanged Flo-tap
First, thread the guide nipple into the
mounting then thread the valve
ODV
The valve stem should be in-line with the pipe
so it will not interfere with the insertion rods
The valve must be a full port valve to allow the
Annubar to pass through the valve into the pipe
Verify the ODV Dimension
The ODV is the dimension from the outer diameter of the pipe to the top
of the valve

After the Hole is Drilled, Retract the Drill
Past the Valve and Close the Valve
Vent drilling machine and remove the per manufacturers
and site procedures
Threaded Flo-tap
Flanged Flo-tap
Remember that the hot tap drilling
machine is under pressure and
exposed to the process fluid
Attach the Fully Retracted Flo-tap
Assembly to the Valve
Threaded Flo-tap
Attach the Fully Retracted Flo-tap
Assembly to the Valve
Flanged Flo-tap – Use a hoist strap and
crane if needed
Quickly Open and Close the Valve to
Pressurize the Annubar, Check for Leaks
If Leaks are Present, Tighten the
Packing Gland Nuts
Loosen the Insertion Limiting Nuts
Simultaneously Tighten the Insertion
Drive Nuts to Insert the Annubar
Lower the Head Plate Lock and Full
Insertion Marking Nuts to the Head Plate

Retraction Limiting
Nuts (Same as
Insertion Drive Nuts)
Loosen the Retraction Drive Nuts to
Retract the Annubar
Other Installation Considerations

During insertion, the rods can twist and the top
plate and support can come out of alignment.
– Makes insertion difficult
– Hit the top plate with a rubber to put them back in-line
