ECS provides evaluation and analysis of corroded fire sprinkler pipe to address two (2) different needs:
- Failure Analysis – in this type of analysis a sample of failed sprinkler pipe from a fire sprinkler system that has experienced a leak is dissected and cleaned to determine the most likely cause for the failure (leak).
- Useful Life Analysis– in this type of analysis a sample of sprinkler pipe is extracted from the fire sprinkler system to determine the level of corrosion (metal loss) that has occurred as part of a risk evaluation on the system. This type of analysis is generally done as part of a corrosion assessment on the fire sprinkler system to determine which piping must be replaced as part of a remediation plan. The FM Global standards for pipe replacement recommendations are generally used with this analysis.
In both of these evaluations a report containing the following information regarding the pipe sample is generated for the pipe sample that is being analyzed:
- Pictures before and after dissecting and cleaning
- Pictures of the point of failure
- Maximum pit depth of the metal loss
- Metal loss characteristics
- Corrosion by-product deposit analysis and elemental composition
- Most likely cause for the corrosion that has occurred
- Recommendation for remediation and mitigation
ECS also provides a second type of more detailed failed fire sprinkler pipe analysis that specifically looks for material defect in the manufacture of the fire sprinkler piping:
Metallographic Failure Analysis
– in this type of analysis a sample of failed sprinkler pipe is evaluated at the granular level using scanning electron microscopy to look for material defect within a cross-section of the metal itself.
In addition to the information provided in failure/useful life analysis, a metallographic evaluation also includes the following information regarding the metal analysis:
- Optical and electron microscopy
- Materials characterization
- Failure analysis
