Why Freeze Pipes?

Commercial and Industrial pipework systems are frozen in order to negate the problems associated with the conventional option of draining, filling and venting.

The freeze isolation is applied to allow the following options to be carried out.

• Valve replacement
• Valve installation
• Radiator removal
• Pipework modification
• Leak detection via hydrostatic pressure testing 

Can any Pipe Be Frozen?

Using the correct equipment most common pipe materiels can be frozen e.g.

Carbon Steel, Mild Steel, Stainless Steel, Kunifer, Copper, Lead, Cast Iron, Galvanised Steel, etc.

 What are the Benefits?

Draining down pipe systems is costly and time consuming, in most instances the water to be drained will include contaminates in the form of inhibitors, glycol, etc.

Pipefreezing eliminates the above and has the added benefit of reducing water wastage when systems are refilled.

Pipefreezing also reduces the risk of oxidization caused by air entering the pipework system through draining down.

Pipefreezing removes the cost of replacing inhibitors.

Can you Freeze Glycol in Chilled Water Systems?

Yes, provided the glycol content does not exceed 35%. CCT have frozen chilled water pipework up to 24"

What pressures can ice plugs hold?

Liquid Nitrogen ice plugs have held  pressures up to 5,000 psi
