As a leading pipe freezing company in London, our team carried out a specialist liquid nitrogen pipe freezing project at the iconic Wembley Stadium, London. The task involved isolating a live 150mm sprinkler main to enable the installation of new pipework and an industrial valve replacement.
The project demonstrated the reliability and precision of our pipe freezing services and showed how our expertise helps clients avoid system downtime – saving both time and operational costs.
Expert Liquid Nitrogen Pipe Freezing Services
Client: DPJ Sprinklers Ltd
Location: Wembley Stadium, London, HA9
Project: Pipe Freeze – 150mm Sprinkler Main to Allow Valve Replacement
Pipe Freeze Project Requirements
We attended the site during normal working hours to complete the following:
- Coordinated with the sprinkler and alarm contractor to manage pipe isolations.
- Gained safe access to the plant room within the stadium.
- Applied liquid nitrogen pipe freezing jackets to the 150mm sprinkler trunk main pipework.
- Formed a secure ice plug to isolate the pipework for the new section to be installed.
- The industrial valve replacement took take place by others.
- Ensured pressure stability and safety throughout the process.
- Released the freeze and checked for leaks after completion.
- Sprinkler and alarm contractor reinstated any isolations.
- Cleared and disposed of all materials at a licensed recycling facility and left the site clean and tidy.
Challenges and Solutions
Working at Wembley Stadium required careful coordination and zero disruption. System isolation needed to be achieved without affecting other areas of the Stadium. Our experienced pipe freezing team used advanced temperature monitoring to maintain a consistent ice plug throughout the procedure. This ensured full control of water flow and prevented unwanted thawing.
We followed strict safety protocols to ensure total control of the system. Every step was carried out under precise monitoring to maintain the safety of the freeze. By using the pipe freezing isolation technique, we avoided draining the entire sprinkler network. This saved significant time and prevented the need to refill and repressurise the system, a process that could have taken several hours.
Benefits to the Client
This project delivered several key benefits:
- Zero downtime: Building systems remained fully operational during the works.
- Reduced costs: No draining or refilling of large pipe networks.
- Fast turnaround: The freeze and valve replacement were completed within standard working hours.
- Environmental benefit: Minimal water wastage compared to traditional isolation methods.
Our client benefited from an efficient, professional service completed safely, on time, and within budget.
