■Capabilities
Visually identify corrosion risks (hydrogen sulfide and sulfur).
Determine
the corrosion category in compliance with ISO 11844-1 based on the
installation period and corrosion length of the Silver Scale™.
Assess the impact of the corrosion category on equipment.
(Reference: ISO 11844-1 standard, ANSI/ISA 71.04-2013 standard)
| Indoor Corrosion Categories |
Impact on equipment |
| IC1 |
- Very low indoor corrosivity |
- Environment sufficiently controlled to ensure that corrosion is not a factor in determining equipment reliability |
| IC2 |
- Low indoor corrosivity |
| IC3 |
- Moderate indoor corrosivity |
- Environment where corrosion may be a factor in determining equipment reliability |
| IC4 |
- High indoor corrosivity |
| IC5 |
- Very high indoor corrosivity |
- Environment where the probability of corrosion attack is high |

| Summary |
Evaluate and diagnose corrosion risks
based on corrosion length |
Diagnose the corrosion risks based on the
corrosion thickness of the metal plate
measured by an analyzer |
| Advantages |
Visual diagnosis of corrosion risks
Remote diagnosis (identifiable through photos, etc.)
Cost-effective |
Highly accurate analysis due to the usage of an analyzer
Environmental assessment for the corrosion of copper, zinc, and carbon steel |
| Disadvantages |
Environmental assessment only for corrosion of metal （silver） |
Collection and analysis of metal plates can be labor-intensive
Expensive |
