Corrosion with Braided Packing
Galvanic corrosion is an electrochemical process that occurs between two dissimilar metals, or between a metal and a conductive non-metallic material, when both are exposed to an electrically conductive media. In the case of a packing gland, it occurs between a metal component and the carbon or graphite packing. Under these conditions, the material that is closest to the anodic end of the galvanic scale will be corroded in preference to the one that is closest

Abrasive media comes in many forms—from mining slurries to wood pulp and even substances as seemingly mild as liquid chocolate. This diversity rules out a one-size-fits-all solution for abrasive pumping applications. However, today’s broad range of materials, from carbon fiber packing to graphite-filled polytetrafluoroethylene (PTFE) bushings, includes products capable of meeting an equally broad range of abrasive wear requirements.

Few materials offer the

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
