❄️ Liquid Nitrogen Pipe Isolation in the City of London

Our experienced engineers recently completed two liquid nitrogen pipe freezes at a commercial office building on Queen Victoria Street.

New valves needed installation on LTHW and chilled water FCU pipework on Level 3. Our team created temporary isolation using liquid nitrogen, allowing the planned valve installation by others to progress.

What happens when liquid nitrogen cools a metal component? ❄️

During liquid nitrogen shrink fitting, controlled cryogenic cooling temporarily contracts the selected metal component.

But what does this process involve, and when can engineers use it?

What happens when a failed valve needs urgent replacement, but the wider water system must remain operational?

At Seven Kings High School in Ilford, a failed valve on the cold water pipework required urgent attention.

Our specialist team used liquid nitrogen pipe freezing to create the temporary isolation needed for the valve replacement to progress.

The project shows how a controlled pipe freeze can support urgent valve works when the failed valve can no longer provide the required isolation.

Discover how our engineers completed the freeze, supported the industrial valve works and safely returned the system to service.

🏥 Specialist Pipework Repairs at Darent Valley Hospital

How do you replace deteriorated 8-inch LTHW pipework in a live hospital environment while avoiding a full system shutdown?

At Darent Valley Hospital, our team delivered a carefully planned pipework solution including:

✅ 4 × 6-inch hot taps
✅ 10m of temporary bypass pipework
✅ New geared butterfly valves and AAV connections

The temporary bypass arrangement helped maintain control of the wider heating system while the affected flow and return sections were isolated and replaced.

The result? Targeted pipework repairs, improved isolation for future maintenance and minimal disruption within a busy healthcare environment.

Industrial valve repair or replacement? A faulty valve doesn’t always mean you need a new one.

When an industrial valve develops a leak, becomes difficult to operate or fails to isolate pipework, what should you do next?

Repair may provide a practical solution. In other cases, replacement could offer better long-term reliability.

But there’s another question worth asking:

How can you carry out the work without draining the wider system?

In suitable applications, specialist pipe freezing can create temporary isolation points within the pipework. This can allow engineers to repair or replace valves while limiting disruption to connected services.

Our latest guide explores:

✔️ When industrial valve repair makes sense
✔️ The signs that a valve needs attention
✔️ Repair vs replacement
✔️ Industrial valve maintenance
✔️ Industrial pump and valve repair
✔️ How pipe freezing can reduce disruption

We’ve also included real project examples showing how temporary pipe isolation can support valve and pipework work in live buildings.

How do you remove redundant pipework without draining an entire building system?

That was the challenge at a commercial office building on London Wall.

Our specialist engineers used liquid nitrogen pipe freezing to create temporary isolation points, allowing redundant FCU pipework to be safely removed across two levels.

The project involved multiple isolation points across both chilled water and LTHW systems, providing a controlled solution while avoiding the need to drain larger sections of the system.

It’s a good example of how specialist pipe freezing can help keep commercial building services operational while essential works take place.

We’re proud to have completed another successful HVAC project, delivering an air-cooled chiller replacement for a hospital.

The new chilled-water cooling system provides:

✅ Energy-efficient cooling
✅ Reliable temperature control
✅ Consistent performance for a critical healthcare environment

Our team managed the installation and commissioning with minimal disruption to the hospital’s day-to-day operations. Helping ensure a reliable cooling solution was in place when it was needed.

Our latest project at the Grade II* listed Time & Life Building on Bruton Street, London, demonstrates how specialist hot tapping services can provide a practical solution.

The works included:
✅ 2 x 1¼" hot taps on 125mm heating pipework
✅ 2 x 1¼" hot taps on 80mm chilled water pipework
✅ TIG-welded threaded sockets
✅ Pressure testing to 10 bar

The existing heating and chilled water systems remained operational throughout the works, which helped minimise disruption and allowed the wider project to progress.

The new outlets were capped and left ready for future use, providing dedicated connection points for planned works and potential system expansion.

This project highlights how hot tapping without shutdown can help M&E contractors, facilities teams and commercial building operators modify suitable live pipework while keeping essential systems operational.
