Pipe Sampling and Evaluations


Pipe Analysis Features

  • Pipe sample is sectioned and media blasted to remove solids and allow for visual inspection

  • Inspection and analysis determines type of corrosion, remaining pipe wall thickness, and calculated corrosion rate in mils per year (mpy)

  • Comprehensive Analysis Report includes photographs of pipe sample before and after media blasting

  • Pipe Analysis Benefits

  • Most cost effective method of corrosion analysis for fire sprinkler systems

  • Determines root cause and severity of corrosion activity

  • Customized corrosion management recommendations provide action plan to prevent future corrosion failures

  • Provides proactive risk management plan instead of maintaining reactive repair and replacement program

  • ECS provides evaluation and analysis of corroded fire sprinkler pipe to address two (2) different needs:

     
    1. 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).

    2. 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:


    • Pictures before and after dissecting and cleaning
    • Pictures of the point of failure
    • Maximum pit depth of the metal loss
    • Metal loss characteristics
    • Most likely cause for the corrosion that has occurred
    • Recommendation for remediation and mitigation

    ECS also provides a 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 includes the following information regarding the metal analysis:
    1. Optical and electron microscopy
    2. Materials characterization
    3. Failure analysis
