3.3 RIM10-700 cold tap installation
The RIM10-700 is non-retractable and must be cold tapped. Process shutdown and line
depressurisation are required for cold tapping. There are two mounting connections
available: Flanged or Screwed.
3.3.1 Installation for flanged connections:

Flanged
Step 1 -
Tap the pipe, the hole should be at least
50 mm (2") in diameter, nominally 50 mm
(2") in diameter.
Step 2 -
Weld the thread-o-let to the pipe.
Step 3 -
Weld the weldneck flange to the weld-o-
let.
Step 4 -
Important
- Attach the tap check tool
to the end of the flowmeter stem before
proceeding:
-
Attach the flowmeter to the flange.
-
Verify that the bleed valve is closed.
-
Use the orientation levers to manually
lower the tap check tool into the pipe
and then retract the tap check tool
completely.
-
Remove the flowmeter from the
flange and inspect the tap check took
for damage.
-
If any has occurred, check the
installation for possible clearance
problems.
Step 5 -
Remove the tap check tool and attach the
turbine sensor (rotor assembly) to the end
of the stem.
-
Verify that the screw and safety wire on
the rotor assembly are correctly
installed.
-
Reconnect the flowmeter to the flange.
-
Verify that the bleed valve is closed.
-
If the flowmeter is supplied with a
pressure transmitter, open the bleed
valve.
-
Do not lower the turbine sensor into the
pipe before calculating the proper
insertion depth.
