How pipe freezing works

When you have a project requiring works to a pipeline system, Pipefreezer provides a quick solution – in most cases, we can perform a pipe freeze without the system having to be shut down, thus maximising your plant’s uptime. We pipe freeze using liquid nitrogen, which enables the safe fluid isolation of almost any type of liquid in almost any size pipe. Using specialist equipment and techniques, a line stop is created in a timely and cost efficient manner via the formation of a solid ice, or cryogenic, freeze plug within the pipeline. Once formed, a freeze plug is highly reliable, can withstand very high pressures in excess of 2000 PSI and is able to be maintained for as long as required while the project is completed.  

We service all industries, including the HVAC, plumbing, engineering and fire services sectors, encompassing industrial, commercial and domestic situations that involve fluid isolation in pipes ranging from 15mm–600mm (external diameter) using pipe freezing, line stopping or hot tapping solutions.

Pipe Freezing

A timely and cost-effective method of fluid isolation in a pipeline system to allow maintenance or modifications to be carried out. Pipe freezing is an environmentally friendly alternative to draining down a system and it’s much faster. An effective ‘cryo’ plug allows operations to continue with minimal disruptions.

Hot Tapping

A solution for isolating liquids at high temperatures and under pressure, the hot tapping process uses a valve fitting on the existing pipeline. For circumstances where pipe freezing isn’t suitable, hot tapping is another alternative to a costly drain down.

Leak Detection

Isolate the location of your leaking pipe using a freeze plug and line stop. Our pipe freezing technology means no matter how complicated your pipeline system is, our leak detection is fast, efficient and involves minimal fluid wastage.
