Field Application Reports Location 112 Pump Repair Products: Titanium Putty / Ceramic Repair Putty / Application Date: Brushable Ceramic Application Customer: Date: 6/1/90 Customer: Industry: Pennsylvania Electric Company Industry: Utility Power Generation Problem: This multi-stage cooling pump would receive extreme abrasive and cavitation wear to the spicket fits, hub area, flange and casing. The wear was so severe the pump efficiency was reduced by 50%. The previous method of repair was to simply replace when required. Replacement cost was estimated to be 28K. Solution: Complete repair areas were sandblasted to a SSPC-SP5 white metal finish. All surfaces were chemically cleaned using Cleaner Blend 300. Titanium Putty was applied to the spicket fits to replace or rebuild missing metal. Titanium was smoothed and contoured using Acetone and a putty knife following gel point. Titanium Putty was also used in the same way to rebuild missing metal on the hub and flange areas. Ceramic Repair Putty was applied to cavitated areas deeper than 1/4”. Following a partial cure of Ceramic Repair Putty and Titanium Putty, (4 hours), Brushable Ceramic was applied to a thickness of 30 mils in two 15 mils coats. Brushable Ceramic provides a long lasting, low co-efficient to friction, protective surface coating.
Field Application Reports Products: Application Date: Customer: Industry: Location 113 Exhauster Fan Repair Titanium Putty / Brushable Ceramic 6/1/90 Pennsylvania Power and Light Utility Power Generation Problem: This exhauster fan would receive extreme corrosive and abrasive wear at the bore or inlet from a combination of fly ash, flume steam and sulfuric acid. The wear was so severe that a new ring needed to be fabricated, welded into position, and then machine to specification. Solution: The complete bore or inlet area was sandblasted to a SSPC-SP5 white metal finish. The surface area was chemically cleaned using Cleaner Blend 300. Titanium Putty was applied to all eroded areas greater than 1/8” deep. Following a partial cure of Titanium Putty, (2 hours), Brushable Ceramic was applied to a thickness of 25 mils. Following a partial cure of Brushable Ceramic, (4 hours), a second coat was applied, again to a thickness of 25”mils. Brushable Ceramic encapsulated repair areas and provided a long lasting, abrasion and corrosion resistant, protective surface coating.
