IDWE is a professional pipe freezing contractor and our services offer the safest, cheapest and most effective method for temporary non-invasive pipework isolation. Pipe freezing using liquid nitrogen makes it easier to carry out valve replacement and other general pipework modifications.

The process is simple but effective. Pipework isolation is carried out by freezing the contents in a controlled method using specialist equipment and monitoring techniques.

Liquid Nitrogen is a fast and efficient way to repair any pressurised pipework. Freezing the pipework and its contents will hold back the fluid in the system so that any repairs or replacements can be carried out safely and quickly.

IDWe’s team of skilled and experienced engineers will ensure the system will not need to be drained down saving valuable time and money and avoiding the costly process of refilling and venting.

We have carried out pipe freezing in many buildings on their Heating & Cooling and Mains Water Systems. See our case studies for examples of our work or contact us for a quote.

Pipework Freezing

Our team carry out in-house pipe freezing using liquid nitrogen to isolate pipework, enabling work to be carried out without the need to drain down pipework. Allowing for minimal disruption and speedy installation work.

Hot Tapping

We make live connections to live pipework systems without the need to drain down or isolate the system, this can be carried out on Gas and Water systems.

Isolation / Valve Fitting

Our team adopt a highly efficient method to react to an emergency situation to reduce any downtime of the system

Welding

We carry out all types of welding from Gas to Arc to MIG & TIG welding either in situ on-site or at our workshop where we can manufacture bespoke pipework installations.
