Plug it by Freezing it....!

The HFT® Pipestoppers® Qwik-Freezer™ Pipe Freezing Equipment uses liquid carbon dioxide (CO2) to freeze stationary water in any chosen sections of pipe or tubing. By producing very low 'dry ice' temperatures, Qwik- Freezer™ forms a secure in-line ice plug.

This temporarily isolates the water in the system and allows repairs or modification to be made without draining or shutting off systems.

Save Money and Time Draining and Refilling

HFT Pipestoppers Qwik Freeze Pipe Freezing Freezer Quick Pipe Stopping

The Qwik-Freezer™ kit is easy to use. A specially designed jacket is wrapped around the pipe at the point where the freeze is required. A nozzle on the jacket is then coupled to a cylinder of liquid CO2 by means of a high-pressure hose. 

When liquid CO2 is injected into the space between the jacket and the pipe, it immediately expands to form a solid carbon dioxide (dry ice) at a temperature of -70ºC (-108ºF). This low temperature quickly freezes the water inside the pipe, forming a secure ice plug, which seals in the pipe.

The ice plug forms only in the section of the pipe covered by the jacket so the resulting rise in pressure is very small and there is no damage to the pipe. The technique can be used safely on iron, lead, stainless steel, copper, brass and plastic pipes.

Portable Pipe Freezing System

HFT Pipestoppers Qwik Freeze Pipe Freezing Quick Freezer

The major advantages of using a Qwik-Freezer™ System:

  • Saves valuable time normally lost draining and refilling a system.
  • Avoids complete shutdown of systems and equipment (as in a sprinkler or water supply system).
  • Prevents large amounts of water wastage.
  • Safe and cost effective.
  • Standard products to suit pipe and tubes sizes from 3/8" to 8" (10 to 200 mm ø).
  • Liquid CO2 is inexpensive. 
  • Other refrigeration systems are more expensive.
  • Long freeze length provides large plug size.
  • Liquid CO2 delivery system is notably colder than other refrigerants.
  • Qwik-Freezer™ Systems allow operators to source their own CO2 (no expensive refills, replacements or refrigerants). 
  • No re-calibration of Qwik-Freezer™ products are necessary.

Freeze Pipes up to 8" (200 mm)

HFT Pipestoppers Qwik Freeze Pipe Freezing Quick Freezer

Pipestoppers® Qwik-Freezer™ is designed and manufactured to suit pipe and tubes sizes from 3/8" to 8" (10 mm - 200 mm ø).

A typical Qwik-Freezer™ application 'replacing a defective valve': 

  • The water in the pipe is brought to a static condition.
  • The Qwik-Freezer™ jacket is wrapped around the pipe (placed at a nearby upstream location).
  • The liquid CO 2 is injected into the jacket.

The CO2 rapidly freezes the water inside the pipe, permitting valve removal for servicing the replacement.

An optional second jacket is available when a double freeze is required to block flow on both sides of the valxe.

Frequently Asked Questions

HFT Pipestoppers Qwik Freeze Pipe Freezing Quick Freezer

1. How do I know how much liquid CO2 I need?
Be sure there is more than enough liquid CO2 on hand for the job (refer to the freezing table in the user instructions for the amount needed to complete the 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. What condition does the pipe and water inside have to be in?
Ensure there is no flow of water through the pipe, as flowing water will not freeze. The outside surface of the pipe must be clean of all foreign matter. Water should be at 20ºC (68ºF) 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 must be colder than 20ºC (68ºF). 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 be double. Do not attempt to freeze close to a main line that has flowing water as the turbulence can prevent formation of the ice plug.

3. Can I freeze pipes larger than 8” or with different material inside the pipe?
Qwik-Freezer™ equipment should not be used on pipes larger than the specified size or pipes containing anything but water. For other sizes and applications, contact Huntingdon Fusion Techniques HFT®.

4. Will I need ventilation whilst freezing?
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

5. Do I need to wear safety clothing?
Gloves and safety glasses should be worn at all times when operating Qwik-Freezer™ equipment. Do not hold dry ice as frostbite could result.

6. Can I freeze on a weld?
It is not ideal to freeze on a weld unless the weld has been x-rayed.

7. What kind of pipes can Qwik-Freezer™ be used on?
Qwik-Freezer™ can be used on iron, lead, steel and copper pipes. It is also applicable to plastic pipes, but these will take up to three times longer.

8. How much water pressure will an ice plug hold?
Ice plugs have passed pressure tests up to 5000 psi. HFT® conservatively rates them to 1500 psi.

9. What about bursting or fracturing pipes?
Pipe fractures are not caused by the ice plug or the freezing process. They are caused by a failure to allow enough space between the ice plug and closed connections. This is due to the increase in pressure that is caused by water that is displaced by the ice plug as it grows that can create a ‘hydraulic ram’ if enough space is not allowed.

10. Why is it imperative to have co2 cylinders with siphon-tubes?
Dry ice is formed when liquid CO2 interacts with the atmosphere (which takes place inside the Qwik-Freezer™ jacket). If a cylinder does not have a siphon-tube it will only deliver CO2 gas, which will have no reaction. Without dry ice, there will be no freeze.

11. What if there is a small amount of glycol or other fluid in the line?
It is important to know how much is in the mix and what the freeze point of the liquid is. Note: the ‘freeze point’ may just be a slush and not to the solid state that is required for a plug. The Qwik-Freezer™ will go down to -121oF.

See what our Users have to say....

02C Qwik FreezeCase Study: Low-cost accessory obviates power station shutdown.
“A new compressor installation, to be completed within a short window of time, was going well until a problem was discovered. The design drawings failed to show that a cold water valve extension handle clashed with the air inlet pipe of the compressor.Critically, this was the only isolating valve from the cooling water main header and could not be moved without closing the cooling water system. This would have also meant shutting down the whole power station, which was not an option.Potential solutions included re-routing the inlet pipework of the compressor and contracting in a specialist pipe freezing company to enable the valve to be moved. All initial potential solutions would have taken time to organise, which could have affected the timely completion of the project.Freezing was considered to be the best option but this valve was welded into place and freezing would have to be made far enough up stream not to be adversely affected by the applied heat from the grinding and re-welding operations.As the water pipe was 75 mm diameter, it was not possible to acquire one of the commonly available domestic or commercial plumbers’ freezing kits, as these only have a capacity up to 50 mm.As time was of the essence, an Internet search discovered a Pipe Freezing Kit for 3” pipe available from the Pipestoppers® Division of Huntingdon Fusion Techniques HFT®. The HFT® Technical team were quickly able to reassure us that Qwik-Freezer™ Pipe Freezing Systems were a proven option for this size of pipe and within 24 hours we had a kit in our possession.Installation was easy and CO2 bottles were obtained from the local BOC gas supplier. The freeze worked well, taking around an hour to freeze the pipe. This freeze allowed time to grind out the welded valve, plus a length of pipe, re-weld a flange back onto the pipe at a new position and install a new valve. The job took around two hours to complete in total and at cost of around 25 per cent of a specialist contractor.”

Accu-Freeze™ Key Features

HFT Pipestoppers Accu Freeze Pipe Freezing Systems Plugs StoppersThe ice plug only forms beneath the Accu-Freeze™ coil wrap, jacket or aluminium clam jacket which is used on a 6 - 12" (150 to 300 mm) pipe or tube and does not expand outside of the range of jacket or coil.

An ice plug is formed by wrapping copper tubing or specially designed insulated jacket around the section of pipe to be frozen. The LN2 is then injected through the patented control system. 

The water or other liquid in the pipe or tube needs to be in a static condition (no flow). The Accu-Freeze™ wrap is placed around the pipe up stream from the section to be repaired.

Accu-Freeze™ takes over by automatically injecting the LN2 to a temperature set by the user through the system over the in-line ice plug. Once the plug is formed, maintenance and repair can take place without draining or shutting off the entire system.

Each unit can be set to 220 V or 110 V and a working scale of oC or oF.

Optional aluminium jackets are available.

Freeze Pipes up to 12" (300 mm)

accu-freeze, qwik-freezer, pipe freezing, tube freezing, liquid nitrogen pipe freezing

The Accu-Freeze™ System is available with a coil wrap, jacket or aluminium clam jacket, which is used on a 6 to 12" (150 to 300 mm).

The design of the jacket incorporates adjustable straps, which will allow the user to alter the jacket size according to the application requirements. 

The controlled freeze process safely creates the ice plug without affecting the integrity of the pipe. (Pipe bursts happen when the ice forms in an uncontrolled manner and creates hydrostatic pressure between ice plugs or against a closure in the line). Detailed user instructions are provided to help the end user select an appropriate location to safely freeze the line. 

In the nuclear industry there are also restrictions regarding exposure of certain pipes to cryogenic temperatures. Accu-Freeze™ makes it possible to create an ice plug while keeping the pipe wall temperature within the allowable temperature limits.

Cryogenic Freeze Seal Jackets (Clam-Shell type) are now available in addition to the standard Accu-Freeze kits.

These Accu-Jackets are popular with customers that need to do repeated freezes on the same size or sizes of pipe. The amount of set-up time is greatly reduced with Freeze Seal Jackets that are manufactured to fit specific pipe sizes and are just bolted around the outside of the pipe.

accu-freeze, qwik-freezer, pipe freezing, tube freezing, liquid nitrogen pipe freezingThe Accu-Jackets have integral injection ports, which connect to the LN2 feed and exhaust ports to vent the gas to atmosphere. They are constructed of high-grade aluminum with a double-wall design that creates an insulating air gap between the liquid nitrogen and the ambient air outside the jackets.

Precision CNC Machined Aluminum Freeze Seal Accu Jackets

  • Doubled walled for superior performance and added insulation.
  • Easy to adapt NPT fittings.
  • Rugged and long lasting for countless freezes.

Frequently Asked Questions

accu-freeze, qwik-freezer, pipe freezing, tube freezing, liquid nitrogen pipe freezing

1.0. What applications is Accu-Freeze™ designed for?
Accu-Freeze™ utilises liquid nitrogen to create the cryogenic temperature necessary to form ice plugs. Freeze sealing is most often used to isolate a section of a piping system where no other ready means of isolation (such as valving) is available. Freeze sealing refers to the process of applying an external refrigerant to a point in a process in order to cause the formation of a solid internal plug from the frozen process fluid contained in the pipe.

2.0. What size pipes is Accu-Freeze™ suitable for?
The Accu-Freeze® insulating jacket accommodates pipe sizes from 6 - 12" (150 - 305 mm). 

Copper coil is used for the smaller sizes.

Aluminium clam shells are available for 2” - 16” (50 mm - 400 mm).

3.0. Is ventilation required?
LN2 is heavier than air and will displace oxygen. Sufficient ventiliation is required, especially when operating in confined areas. 

4.0. What protective clothing should be worn when operating the Accu-Freeze™ System?
Protective clothing i.e. gloves, goggles etc. must be worn at all times when operating the Accu-Freeze™ System. 

5.0. Can I freeze on a weld?
It is not ideal to freeze on a weld unless the weld has been x-rayed.

6.0 Can I freeze contents that are moving within a pipe?
No, the liquid contents of the pipe have to be stationery and non-vibrating

7. 0 Can I freeze liquids other than water?
Yes, milk, beer are all examples of other liquids that can be frozen. Some liquids containing refrigerants can be frozen too, just check with our Technical Team on the type and % content.

8. 0 Can I do a freeze either side of the repair joint?
Yes, this is called a double freeze and necessary accessories can be purchased along with the Accu-Freeze™ kit. A double freeze is required when a valve needs replacing for example.

9.0 What kind of pipes can Accu-Freeze™ be used on?
Accu-Freeze™ can be used on iron, lead, steel and copper pipes. It is also applicable to plastic pipes, but these will take up to three times longer.

10. What about bursting or fracturing pipes?
Pipe fractures are not caused by the ice plug or the freezing process. They are caused by a failure to allow enough space between the ice plug and closed connections. This is due to the increase in pressure that is caused by water that is displaced by the ice plug as it grows that can create a ‘hydraulic ram’ if enough space is not allowed.

11. What if there is a small amount of glycol or other fluid in the line?
It is important to know how much is in the mix and what the freeze point of the liquid is. Note: the ‘freeze point’ may just be a slush and not to the solid state that is required for a plug.
