Installing Equipment
1. Injection tool (IT).
Connect 12 to 18 inches of 1/8” tubing
to the Injection Tool (IT).
Connect a 1/8” x 1/8” ball valve for
typical injections.
Ultrinium 733 fluid can thicken severely
at temperatures below 50°F (10°C).
Using a 1/8” x ¼” ball valve may
improve injection times with long tube
lengths.
Figure 1: Connect a ball valve
to the injection tool.
Install the liquid flow meter (rotometer).
Secure the liquid flow meter to the tank that is being used.
Figure 2: Liquid flow meter.
Figure 3: Flow meter secured on tank.
Connect the tank’s injection port (colored red) to the inlet of the flow meter.
Connect the tubing from the ball valve to the outlet of the flow meter.
Attach the injection tool to the IA, as in NRI 452.
Close all valves on the feed tank, flow meter, tubing, and gas tanks.
2. Pressurized feed tanks.
Attach an inline pressure gauge to the CO2 regulator of the used gas tank.
Select an inline gauge with a pressure range appropriate for the injection.
Connect the inline gauge to the feed tank.
Wheel the CO2 regulator out to prevent accidental over-pressurization.

Slowly pressurize the feed tank to the lesser of the adjusted flow pressure (AFP) or the maximum
working pressure rated for the tank.
If the AFP isn’t known, use NRI 352 to calculate the AFP.
The AFP can be increased by 10% for attended operations. However, if the injection needs to be
left unattended for any reason, reduce the pressure to the normal level.
This helps reduce the effects of any leaks that would have been found if attended.
Read the pressure on both the inline gauge and tank gauge. The two readings should be close to each
other.
Check the tank for any leaks.
If any leaks are found, relieve all pressure immediately and fix the leak.
A pressure relief valve prevents hardware operation above the design pressure. Do not tamper
with the pressure relief valve.
3. Receiver tanks.
On the receiver end of the cable sub-segment, install an injection tool connected to an empty
graduated flush bottle with 1/8” tubing. There are many sizes of flush bottles available.
Figure 4: Connect a flush bottle to the receiving injection tool.

A 140mL aluminum tank with a ball valve may substitute for the flush bottle in normal and unattended
injections. The ball valve allows injection to continue while the valve is closed.
Figure 5: 140mL tank with ball valve.
When possible, attach the
graduated flush bottle for easy
measurement of flushed fluid.
If left unattended under any
circumstances, place the flush bottle
or tank in a basin to prevent
accidental spills.
Figure 6: Use a spill basin to guard
against spills and overflow.
Pre-Injection Check
1. Check for leaks.
Before sending fluid straight to the cable, make sure each part of the injection assembly is leak-free. If
any leaks are found in the following process, close all valves, relieve pressure, and fix the leak.
Double-check that all valves on the feed tank, flow meter, tubing, and gas tank are closed.
Open the valve on the feed tank’s injection port. This will send fluid to the liquid flow meter. Wait for
three to four seconds and watch for leaks.
Open the valve on the liquid flow meter. This will send fluid to the inline ball valve. Wait for three to
four seconds and watch for leaks.
If no leaks are seen in the assembly, open the ball valve to send fluid to the injection tool. Watch for
leaks coming from the injection tool or the interface between the tool and the IA.

Recording Tank Levels
1. Record the injection start time and feed tank level.
Record the feed tank’s starting fluid
level in millimeters (mm) from the
bottom of the meniscus in the sight
gauge.
Record the injection start time.
Enter this information into
Knomentous.
Figure 7: Read the level from the
bottom of the fluid meniscus.
Starting the Injection
1. Flow check.
Verify flow into the cable by looking at the BBs in the liquid flow meter.
The BBs should rise to the top of the glass tube when flow starts and then slowly drop as flow
stabilizes.
If the BBs are dropping rapidly, there is a restriction in the cable.
Verify flow through the cable by checking the tubing on the receiver end of the cable.
Build up pressure in the line or submerge it into fluid.
Relieving the built up pressure should be audible, and air flow should cause bubbles in the fluid.
Bubbles may appear slowly due to restrictions in the cable.
2. Flush water and other fluids.
If water or other fluids are in the cable,
you may need to empty the receiver
bottle or tank multiple times during
injection.
To measure the flushed fluid, transfer all
fluid to a graduated flush bottle, if not
already in one.
Let the bottle sit for a few minutes. Water
and other fluids should separate if left
still.
Read the water and fluid levels on the
side of the bottle.
Figure 8: Transfer all fluids collected in the 140mL tank
to a graduated flush bottle.

Record all fluid and water flush and enter
the total volume into Knomentous.
3. Read the liquid flow meter.
The liquid flow meter shows the volume of fluid flowing through the glass tube every minute. It does
this by moving the two small BBs (one black, one silver) in the liquid flow meter’s glass tube.
The black BB is tinted black glass, while the silver BB is stainless steel. The black BB is more sensitive to
flow than the silver ball and must be located above the silver BB.
If the BBs are reversed, clearly label and contact supply chain to exchange for a new liquid flow meter.
The backing behind the glass tube has two scales printed on it. The left side, marked with “Silver ball”,
is the scale to read the silver BB’s position. The right side, marked with “Black ball”, is the scale to read
the black BB’s position. The unit of measurement of both scales is in mL/min, which is the same as
cc/min.
Figure 9: Black and silver ball scales.
Figure 10: Units of both scales.
When the black BB is above 11 cc/min on its scale, begin using the silver BB and its scale for readings
until the black BB drops back below 11 cc/min.
Monitoring the flow through the liquid flow meter can reveal much about the cable.

oA gradual decline in flow rate
means a clean cable.
oA sharp drop off in flow rate means
a restriction or blockage.
oA sharp drop near the start of
injection is a restriction/blockage
near the feed end of the cable.
oIf the restriction/blockage is
farther along the cable, it will take
longer to reach a sharp flow rate
drop.
Figure 11: Depiction of flow rates.
Estimating Fluids
1. Estimate the current supplied fluid.
Note the current fluid level in
millimeters (mm).
Subtract the current level
from the starting level.
Figure 12: Find the starting and current fluid levels.
To find the total fluid volume
in cubic centimeters (cc),
multiply the difference by the
tank factor for the feed tank
being used. Tank Factors can
also be found on a sticker on
the tank or in NRI 412.
2 or 3 Liter Tank Factor:
8.33 cc/mm.
9 Liter Tank Factor: 33.3
cc/mm.

2. Estimate time for fluid arrival.
Calculate how much time has passed since the injection began.
Use NRI 302, “The Cable Table”to calculate the target fluid amount the cable will take in millimeters
of tank height.
Divide the calculated target by the millimeters of fluid currently injected into the cable.
Multiply this number by the amount of time the injection has currently taken. This is the estimated
amount of time left for injection.
Fluid Arrival
1. Flush the cable.
Flush any contaminants out of the
cable.
Continue to flush until at least
25cc of clear, clean fluid comes
out of the cable.
Figure 14: Flush the cable.
2. Reduce pressure to the tailored injection pressure (TIP).
Reduce the adjusted feed pressure (AFP) to the insulation type’s tailored injection pressure (TIP).
The XLPE insulation TIP can be found in NRI 302, “The Cable Table.”
If the EPR insulation TIP is needed, calculate by dividing the XLPE TIP by 4.
3. Pin the outlet.
Close the ball valve to the injection tool to prevent fluid spray.
Use the injection tool to insert the plug pin into the IA; then remove the injection tool from the IA.
Check the plug pin hole for leaks and tap the pin in if it is not flush.
Wrap the saddle chain around a rag to protect and keep debris out of the injection tool.

URD Cables and Pressurization
Cables with small interstitial areas (space
between the strands) compared to the
insulation size need to be pressurized.
Typically, cables 250MCM and smaller need to
be pressurized. Extra fluid needs to be forced
into the strands with pressure.
If you have questions, contact engineering.
If the cable to be injected is of at least
350MCM size (Feeder) or is rated for a much
higher voltage level, follow the pressurization
procedure as stated in NRI 613 Large
Diameter Cables (Feeder) - SPR.
Figure 15: Thin insulation compared to the
conductor.
1. Flow rate signals the end of injection.
After pinning the outlet end, the flow into the cable will naturally begin declining as the fluid fills the
voids in the conductor.
Longer runs will take longer to drop.
The flow rate should eventually drop to 1cc/min or less.
If flow doesn’t drop to this level, there may be a leak somewhere in the system.
Search and repair fluid leaks at both cable ends.
If no leaks are found, there is either a fault or an undetected splice in the cable.
Locate and repair the splice or fault.
Re-inject the cable sub-segments.
