Problem: Altrad services coating department were recently approached by EDF Energy to assist with encapsulating approximately 140 flanges to the turbine stator water system. The flanges were being encapsulated due to air being drawn into the system, from the vacuum side of the stator water. These levels were higher than normal, so rather than taking the full system or unit out of service, Belzona 3412 would be used for the task, until the system could be brought out of service for maintenance.
