Application Situation

A leaking water cooling pipeline within a Nuclear Power Plant.

Application Method

The pipeline could not be shutoff therefore grit blasting was not allowed. Surface preparation was therefore done using a Belt Sander & Grinder. The leak was plugged using Belzona 1212 and any pitting rebuilt using Belzona 1161 due to its surface tolerance prior to Belzona SuperWrap II being applied. The application was carried out in accordance with Belzona System Leaflet VPF-11.

Belzona Facts

The application was carried out whilst the pipeline was in service therefore eliminating any downtime. The repair was also standards and calculated in accordance with ISO24817 with a 20-year design life.
