expansion joint failure
- May 07, 2021
During an initial expansion joint Preventative Maintenance and Reliability (PMR) Service performed at the paper mill, it was determined that several competitor joints required replacement. These pipelines carry water, pulp, black/white liquor, bleach, and CIO2.
Though recommended for replacement on the Garlock Preventative Maintenance and Reliability (PMR) report, the mill postponed purchase. To date, four of those items flagged for replacement have failed - with the most recent failure resulting in an administration building filling with 4 feet of pulp.
