Transcript

1. Calpine Cooling Tower Maintenance Example Coating Project at King City July 2012 by Pan Pacific Supply
2. The Vendor Pan Pacific Supply is an approved Calpine vendor. Completed 2012 Projects: Calpine King City Phase I Pending 2013 Projects: Calpine Yuba City Calpine King City Phase II Call Dan Collier of Pan Pacific for more information:
3. Benefits: • Multiple Functionality • Waterproofing • Corrosion Protection • Chemical Resistant • Money Saving • Lower preparation costs with power wash only • Long Lasting results • Health and Safety • No VOC’s – Exceeds California Standards • Cannot be sparked and ignited • No Sand Blasting required Pan Pacific Supply uses Perlastic because:
4. Repair of a Cooling Tower floor Pin Hole Perforations • 900% coating elongation • Tietex integrated fabric Corrosion Protection • 80 mils thick coating will prevent corrosion • No pin holes will return Chemical Resistance • Good Sulfuric Acid resistance • Excellent Salts resistance Example: Calpine King City using Perlastic Coating by CETCO
5. The Coating Process Day One • Drain and remove filler block • Clean the floor with power washing “no sand blasting” to water line Day Two • Prepare with Perlastic RG & Tietex to bridge perforations & make transitions • Spray Perlastic SG to 80 dry mils Day Three • Remove masking & replace filler block while maintaining fan movement • Perform QC procedures 3 or 4 days to complete
7. Prior Condition
8. Unloading filler blocks
9. Inspection after waste mud removal.
10. Sulfuric Acid tray with corrosion to failure on some struts.
11. Setting Up for “Hotsy” Power Washing – No Sand Blasting is required prior to coating.
12. Cleaned and ready for Coating Preparation with Perlastic RG.
13. Masked Heating Elements and side walls ready for spray coating.
15. Floor partially sprayed with special attention to the bolts Note: Fan set up for accelerated cure based solely on air movement. Walkable in 20 minutes or less.
16. Removal of masking materials and minor touch up.
17. Turn on the Cooling Tower Fans and cure it out rapidly.
