Heathrow Airport – Seized Fire Main / Valve ReleasingThis was an emergency response for London Heathrow Airport. It involved freeing a 12 inch valve on the fire main. Replacing this valve would have involved the excavation of the hangar floor to a depth in excess of 16 feet and freezing the pipeline with liquid nitrogen. This process is very expensive and involves loss of supply. With our unique technology, there was no loss of supply and the valve was released in less than one hour. |
