OPERATING INSTRUCTIONS
Step 1: Setup Preparations
1. Be sure there is more than
enough liquid CO2 on hand
for the job (refer to Freezing
Table for the amount needed to
complete initial freeze only). If
you intend to hold a freeze, extra cylinders will be needed. Use
only cylinders fitted with a siphon tube or dip tube.
2. Keep the cylinder upright and keep it cool. The unit operates best
when the temperature of the cylinder is kept below 25˚C (77˚F).
It will not work if the cylinder temperature reaches 32˚C (88˚F).
Keep the cylinder out of direct sunlight. If necessary keep the
cylinder in a drum filled with water and ice.
3. Make sure there is no flow of water through the pipe. Flowing
water will not freeze. Ensure outside surface of pipe is clean of all
foreign matter.
4. Water should be 20˚C (68˚F) or colder. Warm water will take
much longer to freeze. Always freeze on a horizontal line whenever
possible. If attempting a vertical freeze the water temperature
must be colder than 20˚C (68˚F). Additional injections and waiting
time will also be necessary. A vertical pipe may take up to twice
as long as a horizontal line and the CO2 consumption will double.
5. Do not attempt to freeze close to a main line which has flowing
water. The turbulence can prevent formation of ice plug. Figure 1
shows how Qwik-Freezer™ should be used close to a main line
with flowing water. A minimum of 12 inch (1" pipe) from water
main is required. For every 1" of pipe diameter, add 12" from
main.

1.
6. Connect hose(s) to nozzle(s) on the jacket and to cylinder(s).
Make sure nozzle is clear and tight. Open cylinder valve briefly
and check that the orifices are clear. If clogged, remove and
clean.
7. Fit the jacket around the pipe by pressing the sealing strips
together and tie cords tightly around the pipe. Some escaping
CO2 is common around the nozzle and end seam of jacket.
8. If a torch is to be used keep the jacket a minimum of 12” away
from the point of repair for each inch of the pipe diameter on
carbon steel. Triple the distance for copper tubing.
9. Double freezing: to block the flow on both sides of the valve, (see
Figure 2) ice plugs must be kept far apart to eliminate pressure
build up. Minimum of 2 feet between plugs is necessary on lines
smaller than 3” in diameter with pressure of 60 Psi or less (see
Figure 2). Higher pressure than 60 Psi will require much greater
separation. Also for pipe diameter of 3-8” separate and additional
1 foot for every inch of pipe diameter.

When freezing close to a valve, the valve should be opened. If
the valve is closed follow procedures for double freezing for the
distance required between the plug and the closed valve.
11. Important: to ensure compliance with freezing table, be sure
to accurately log all information on timing log included with each
Qwik-Freezer™ kit.

Step 2: Beginning the Freeze
1. Open cylinder valve fully and inject liquid CO2 (for times see
Freezing Table). The jacket will fill with solid dry ice. (after more
than 1 injection).
2. Important: during the freezing period break up the formation of
dry ice by pressing jacket firmly and vigorously tap the jacket
with rubber mallet to ensure dry ice is packed evenly around the
pipe and in contact with the pipe for the best results. On pipe
diameters of 4-8" it may be necessary to shift the jacket 90˚ after
each of the first, second and third injections to distribute the dry
ice more evenly before starting break up.Always allow sufficient
waiting time between injections as indicated in the Freezing Table.

Note: the above table is for typical freezing of static water ar 20˚C (68˚F) in Schedule 40 steel pipe. Higher
temperatures will require additional injection and waiting time periods. Plastic pipe will take up to 3 times longer.
For freezing applications on pipes larger than 8" (200 mm.) I.D. please contact HFT®.

Step 3: Proceeding with the repair
1. Following completion of all injections and waiting periods as
indicated in the Freezing Table a wide band of frost should have
formed on the outside of the pipe near the edges of the jacket.
The band must cover the full circumference of the pipe. The frost
band alone is not a guarantee of a completed ice plug. Before
proceeding with the repair, check at a valve, flange or vent to be
sure that the plug has fully formed.
2. The ice plug will easily withstand normal water pressure up to
300 Psi.
3. To maintain the ice plug, make an additional injection every 10 to
15 minutes. (check freeze every 5 minutes).
4. For welding or cutting near freeze refer to Step 1.
5. Upon finishing the repair remove the jacket and allow pipe to
thaw naturally. Do not use a torch as this could damage the pipe.
If possible back fill pipe with water to speed the thawing process.

SAFETY PRECAUTION
1. Qwik-Freezer™ equipment should be used only to freeze
stationary water in a selected section of pipe or tubing. It should
not be used on pipes larger than specified in Freezing Table or pipe
containing anything but water. For other sizes and applications,
contact Huntingdon Fusion Techniques HFT®.
2. CO2 is heavier than air and will collect in confined and low lying
work areas. To prevent the danger of asphyxiation, make sure
there is always good ventilation. Ventilation fans must be used in
confined and low lying spaces.
3. Wear gloves and safety glasses at all times when working with
Qwik-Freezer™. Do not hold dry ice, frostbite could result.

PAGE 10
TROUBLESHOOTING
If dry ice does not form, check the following:
1. Qwik-Freezer™ cylinders are equipped with a siphon tube which
may have broken. Have a proper carbonic gas dealer check the
cylinders siphon tube.
2. If you are not using a Qwik-Freezer™ cylinder it is possible that
your cylinder is not equipped with siphon tube or the tube is too
short. (a minimum 1/4" from the cylinder base.)
3. Was the cylinder full when you started the freeze?
4. Was the cylinder warmer than 20˚C (68˚F)? (see Step 1).
5. If there flow in the line? Flowing water will not freeze. All steps
must be taken to bring water to a static condition.
6. Pipes must be completely full of water. If unsure vent air from
the pipe.
7. Hot water lines should be allowed to cool to room temperature
before attempting a freeze.
8. If there is glycol (antifreeze) in the pipe do not attempt freeze.

HFT Pipestoppers ® Nylon Pipe Plugs
are suitable for a myriad of applications.
They are mostly used for weld testing,
leak testing of pipework fabrications, weld
purging or simply stopping to prevent the
ingress of dirt, rodents and other unwanted
material. These plugs will provide airtight
seals and in tests with plastic pipes they
are capable of sealing against pressures
from 60 Psi - 4 bar, to over 100 Psi - 7 bar.
HFT ® manufactures a large range of
Aluminium Plugs, suitable plugs for
leak testing and isolation, to compliment
the range of small diameter Nylon Plugs.
All natural rubber rings can be replaced
with silicone, nitrile, neoprene or viton
for chemical and temperature resistance.
Steel Expanding Single & Double
Plugs for pressure testing and stopping all
pipework from 1.5 inch (38 mm) upwards.
The test pressure capability of the single
stoppers is limited and the double versions
increase that capability, while offering a
greater stability in the pipe.
Rim Fastening Steel Plugs, single and
double port, for pressure testing and
stopping all pipework from 17” (432 mm)
up to 95” (2400 mm). Rim Fastening Steel
Plugs, especially the large sizes, have
the advantage over centre locking plugs,
that the nuts enable plates to be closed
together evenly with ease and even seal
in pipes that have slight out of roundness.

HFT Pipestoppers® Inflatable Stoppers
and Test Plugs, an easy way to stop the
flow of gas or liquid along a pipe or duct,
for collection of debris and to prevent
ingress of unwanted material or animals.
All Inflatable Stoppers are manufactured
with a strong internal inflatable bag
made to the required shape and covered
in waterproof sewn polyurethane coated
nylon for low friction and to prevent
the production of static electricity or
accidental sparking.
The Inflatable Stoppers range includes;
Spherical, Cylindrical, Heat
Resistant and the Specials.
PetroChem Stoppers suitable for
arduous duties such as immersion in
chemicals and/or higher temperatures.
The Inflatable Rubber Stoppers
each have a wide diameter range and
are suitable for use in petrochemical
applications, as well as many others.
These low cost Pancake Stoppers are
manufactured for applications where
there is insufficient length of pipe for
the regular Cylindrical and Spherical
Stoppers.
