Long-term Wear Protection with Devcon® Wear Guard™ 300RTC

Problem

Pump Box with Baffles in potash mine undergoes high-temperature wear, erosion and corrosion. This wear is caused due to continuous exposure to high temperature saline processing solution. As a result, the equipment needs to be pulled offline,
cleaned and recoated frequently to repair the damage. In addition, the current process and coating requires the equipment to be moved offsite for a post bake cure, further increasing downtime and maintenance cost.

Process Conditions

• Wet slurry with a consistency of 60% solids
• High salinity concentration
• Temperatures that may reach up to 225°F / 107°C
• Continuous erosive & corrosive wear conditions

Solution

To achieve the desired results, three products including Devcon Wear Guard 300RTC were trialed:
• Competitor A’s product was applied to the baffles of the Pump Box. The product initially adhered to the baffles but suffered catastrophic bond failure within a few weeks of application.
• Competitor B’s product was applied to the interior walls of the Pump Box. The product adhered to the walls but had begun to wear in several spots.
• Devcon Wear Guard 300RTC coating was applied to the baffles of the Pump Box. The coating adhered to the pump box baffles and after 3 months of service had not shown any signs of wear

The Pump Box was inspected at 6 months:

  • Competitor B’s product had worn off in numerous spots.
  • Devcon Wear Guard 300RTC coating was still adhering to and protecting the baffles.
