High TDS Corrosion Study
Untreated Seawater versus
Silica Treated Cooling Tower Water |
|
| |
- High TDS (Seawater) inhibitor study
- Untreated seawater - 35,000 TDS (25°C)
- Inhibited Water - 50,000 TDS (88°C)
- Silica prevented MS and 316L attack at 88°C
- Seawater very corrosive to MS even at 25°C

Industrial Cooling Tower
Mild Steel Corrosion Study |
| |
- 60 day MS corrosion rate was 0.2 MPY
- Slight corrosion only under coupon mount
- Tower water at 65,000 TDS (80 COC)
- Chloride 5000 Mg/L, Sulfate 8000 Mg/L

High Temperature Inhibitor Study
Mild Steel in High TDS Water |
- Temperatures from 25 to 88°C (77-190° F)
- Silica inhibited water at 50,000 TDS
- MS general corrosion < 0.3 mpy at 88°C
|
| |
|
- MS localized (pitting) < 2 mpy at 88°C (190° F)
- Silica inhibitor will permit use of MS in
high temperature exchanger applications
