Field Application Reports Products: Application Date: Customer: Industry: Location 11 Stainless Steel Turbine Runner Repair Ceramic Repair Putty / Titanium Putty 2/18/95 Ontario Hydro Saunders Generating Station Utility Power Generation Problem: These turbine runners would receive extreme cavitation wear from the high volume flow of water. Cavitation on runners causes secondary problems such as vibration and off balancing. Runner replacement cost was estimated to be 50K. Solution: The complete repair area was first roughened using a grinder and wire wheel attachment. Repair surfaces were then chemically cleaned using Cleaner Blend 300. Ceramic Repair Putty was applied rebuilding missing eroded metal. Ceramic Repair Putty was smoothed and feathered using acetone following gel point. Following a full cure of Ceramic Repair Putty, (16 hours), Ceramic Repair Putty was sanded to a smooth finish. Devcon’s repair cost was $400.00.
Field Application Reports Products: Application Date: Customer: Industry: Location 12 Power Pole Repair Flexane® 80 Liquid Fast Cure 3/21/96 Ontario Hydro Utility Power Distribution Problem: These utility power poles would receive extreme damage from nesting woodpeckers. The woodpecker would peck a nest as deep as five feet from the entrance hole. This damage would leave only a wooden shell offering little resistance to wind, ice, and snow. The damaged pole could no longer support the weight of the cables and required replacement. Power pole replacement cost was estimated to be $4K Solution: An injection port was first drilled into the power pole above the repair area. Wooden dowels were place into the void. Placing wooden dowels reduced the volume of Flexane 80 Liquid Fast Cure required to fill the void. Flexane 80 Liquid Fast Cure was injected through the injection port. Flexane 80 Liquid flowed evenly throughout the void rebuilding the missing wood. Devcon’s repair cost was $300.
