CUSTOMER BACKGROUND
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.
CHALLENGES FACED BY CUSTOMER
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.

SOLUTION AND BENEFITS
Due to these recent failures, there is now a sense of urgency at the plant to have Garlock expansion joints specified throughout the facility. All rubber expansion joints for this mill have been specified as Garlock Style 204, single filled arch, EPDM tube, no equal for water and pulp applications and Garlock Style 204 with GUARDIAN® FEP liner (formerly Style G200), no equal for black/ white liquor, bleach, and CIO2 applications.
Garlock expansion joints offer superior performance, reliability and service life. This in turn improves plant safety, increases the mechanical integrity of equipment and allows customers to gain a competitive advantage in the market place.
