Application Situation
Emergency service water system, (cooling water to containment air coolers)
Application Method
Application was carried out in accordance with Belzona Know-How Leaflet VPF-13. Formers treated with Belzona® 9411 were used to form Belzona® 1111 to a thickness of 0.128" on each flange face to allow for leak free assembly.
Belzona Facts
Replacement of the system at a cost of $270,000 was considered but the Belzona alternative, which cost $7,000, was chosen and design basis accident (DBA) testing provided the customer with a repair product which eliminated the expense of welding in new flanges which would have taken three weeks as opposed to the four days taken with the Belzona repair.
