Mark the Locations for Drilling the
Mounting Holes

Mark the location for the first hole

Use a pipe tape to find and mark the location of
the opposite side hole
Drill the Holes into the Pipe Using a
Drill Bit or Hole Saw
The mounting
holes must be
180° degrees
apart to ensure
Tag with correct drill hole
size attached to the Annubar

Clean the Area with a Grinder to
Prepare for the Surface for Welding
Mounting Should be Welded So the
Bolt Holes Straddle Pipe Center Line

The mounting
hardware should be
gapped 1/16th inch for
welding
– Use weld rod to do this

It should also be
centered over the
drilled hole
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

Complete a Continuous Weld Around
the Perimeter of the Unit
Insert the Annubar Sensor to Align
the Opposite Side Support (OSS)
Round tip of
the Annubar
Sockolet or
threadolet
Welded or
threaded
OSS Plug
The tip of the Annubar should engage the
OSS Support Plug a minimum of ½ inch
Gap the Threadolet or Sockolet 1/16”
and tack weld it into place

With the Annubar
inside
Remove the Annubar and Complete a Continuous
Weld Around the Sockolet or Threadolet
Weld or Thread the Opposite Side
Support Plug
Threaded OSS
First wrap the threads with the
appropriate tape sealant. Then thread
the OSS Plug into the threadolet.
Welded OSS
Insert the OSS Plug into the Sockolet,
then gap it 1/16” (provides socket weld
gap) and tack weld it in place. Then
complete a continuous weld around the
OSS Plug.
The Annubar Sensor should not be
installed for this step (This would cause
irreparable damage to the Annubar)
Insert the Annubar

With the appropriate gasket

Verify the flow arrow on the side of the Annubar
is pointing in the right direction
Tighten the Bolts in a Cross Pattern
to Appropriate Torque Specification
