Belzona Facts
Sheet metal shields were produced to go over the diaphragms. Welding was considered, but time and costs associated with that were prohibitive. They were able to avoid the excessive cost of welding and its extended downtime. The Belzona approach kept the equipment out of service only one week, thereby keeping the power plant on schedule during their planned outage.
