IDWe Ltd at a Glance


  • How does pipe freezing work?

    Fit a pipe freezing jacket, apply liquid nitrogen onto the external surface of the pipe where the jacket is sitting. The nitrogen then cools the exterior of the pipe enough for the liquid to solidify. The frozen fluid isolates a section of the pipe so that repairs or modifications can be carried out.

  • Can you carry out pipe freezing for all pipelines?

    We will freeze metallic pipework, but we will not freeze plastic pipes. However, there is an alternative method. Please enquire now on 020 8302 7644.

  • What’s hot tapping?

    Hot tapping is the process that facilitates making a new connection to existing pipework. This connection allows for a new line or branch to be added, with no disruption to services.

  • What are the benefits of hot tapping?

    You save time and money as you don’t have to drain the system down or isolate the system. The pipework can remain in use while welding onto the live pipework.

  • What’s the cost of Air Conditioning?

    This all depends on preference, unit type, size of the site and more. We will provide the most economical solution depending on the specification.

  • What’s the most common fault with installing Air Conditioning?

    Design. You need experienced installers to design the units correctly or the air capacity will not work for the space you need it for.
