Material Properties Assessment

Material Properties Assesment

An important factor in establishing pipe properties, in-situ material properties assessment is used to determine the mechanical properties of pipe steel, including yield strength and tensile strength. By combining this information with additional assessment data, pipeline owners and operators can generate pipe grade and records documentation needed to support maximum allowable operating pressure/maximum operating pressure (MAOP/MOP) validation.

Best used for: gas transmission and hazardous liquids pipelines

Key features:

  • Performed in-situ, while the pipeline remains in service at full pressure.
  • Provides identification of mechanical properties on a joint-by-joint basis.
  • Determines yield strength and tensile strength.
  • Final results delivered within days, not weeks.


  • Can this process be used on legacy pipelines? Yes. It is appropriate for all pipe vintages less than or equal to 70Ksi.
  • As a pipeline operator, will this help me meet the need to establish traceable, verifiable, and complete records? Yes. Material properties assessment is among the key techniques used to ultimately determine pipe grade in situ, non-destructively. A final report complete with yield and tensile strengths, chemical composition, and grade calculation, among other details, is provided for each joint of pipe evaluated.
