Application Situation

Cruise ship flange gasket rebuilding.

Application Method

Application was completed with a modified version of Belzona System Leaflet GSS-1 for creating gaskets. Damaged gasket material was removed. Steel substrate was cleaned and abraded with a grinder and MBX Bristle Blaster. The surface of the flange was then treated with a thin coat of Belzona 2911. Once the conditioner cured the flange face gasket was built up with Belzona 2121. A custom former or Blank that had been coated with a release agent was then lightly bolted onto the flange face to reform the gasket. Once Belzona 2121 had cured the former was removed to reveal the new gasket. Any excess material was then cut away with a razor blade.

Belzona Facts

This cruise ship was in dry dock for a very limited time to complete a major rehab and needed to be back in the water in a matter of days. Belzona provided a custom fit and the job was completed within a few hours keeping the schedule intact and avoiding major penalties.
