Why doesn't the pipe break?

The water freezes from the outside in concentric layers and the final expansion is taken up by the water on either side of the plug.
This principle only applies to water lines, since all other liquids contract, rather than expand, on cooling.

How long will it stay frozen?

The pipe will stay frozen indefinitely, as long as Nitrogen is fed to jacket the pipe will remain frozen.

How close can work be performed?

The ideal amount of space should be 20 diameters.  These conditions rarely exist in the field much closer work has been performed.  Contact Us for individual situations.

What sizes can be frozen?

We are able to freeze pipes from 3/8" to 48"

What types of pipe can be frozen?

  • Carbon Steel
  • Stainless Steel
  • Transite
  • Aluminium
  • Cast & Ductile Iron
  • Coated & Lined Pipe
  • Cooper
  • Lead
  • Titanium
  • 3/8 Inch to 48 Inch
  • Vertical, Horizontal, Inclined
  • Out of Round

Is it Eco Safe?

It is environmentally friendly Nitrogen is 79% of the air we breath. It is also totally inert.

How does it work?

Pipe Freezing causes a section of the pipe to freeze using Liquid Nitrogen or CO2 surrounding the section gradually removing the heat which will freeze the content soild.

Can you freeze moving water?

To carry out a successful freeze, the liquid to be frozen should ideally be static.  This condition does not always exist and sometime the flow of liquid is too large for a freeze to be successful.  (Feel free to Contact Us for additional details)

Can you freeze a 1/2 full pipe?

It is essential that the line is full of liquid otherwise formation of a plug is not possible.
