Hydrant System Mothballing

Meccon was contracted to mothball the existing hydrant system at terminal D for United Airlines. We had to prep the system with blind flanges and ball valves to facilitate the removal of all the fuel and nitrogen filling of the system after the modifications were made. We had a small off hours window to shut down the fuel and blind off the terminal D system from the rest of the truck load rack. This project was a great success with no airline delays. After the system was drained down Meccon then filled the system with a nitrogen purge and repair some existing pavement issues near some of the hydrant pits.
