To enable the introduction of a new branch. Required on site to stop the LTHW water flow with our pipe freezing services to allow others to carry out works.
Pre-Freezing Preparation
Before our arrival, we instructed the client to isolate the boiler and pump 12 hours in advance. This step ensured the pipework reached the necessary temperature for freezing.
Executing the Pipe Freezing Process
Our task involved performing four liquid nitrogen pipe freezes during normal working hours. We applied two freezes on the LTHW 50mm flow pipe. First, we secured freeze jackets around the pipework, ensuring a tight seal for effective freezing. Then, we filled the jackets with liquid nitrogen, creating solid ice plugs that completely stopped the flow.
Isolating the Return Pipework
Next, we repeated the process on the LTHW 50mm return pipework. The second set of freezes provided full isolation, allowing modifications without draining the system. By using pipe freezing, we eliminated the need for costly and time-consuming drain-downs.
Safe System Modifications
Once all four freezes had taken hold, other contractors could safely complete their work. This method ensured a controlled and efficient environment for adding a new branch to the system. No water loss occurred, and system integrity remained intact throughout the process.
Controlled Freeze Release and Leak Checks
After their modifications, we carefully released the freezes, allowing a controlled return to normal flow. We then conducted thorough leak checks, ensuring a secure and reliable reconnection. This step guaranteed that the system functioned correctly before we completed our work.
Site Clearance and Waste Disposal
Finally, we cleared the site of all equipment and waste materials, maintaining a clean and organized workspace. We disposed of all redundant materials at a licensed recycling facility, adhering to environmental regulations. This approach ensured a safe, compliant, and hassle-free project completion.
Result of Works
As it was decided to not drain down the whole system and use our pipe freezing services, there was minimal disruption to services.
In conclusion, the valve was ready to be used to connect onto the cold-water supply.
