Pipeline operators are faced with many difficult challenges on a daily basis. Strict regulations and the negative consequences of an accident make integrity management decisions increasingly important. The juggling act of maintaining a balance between safety, supply, and the bottom line is monumental. ABI® Services, LLC (ABIS) provides an alternative to costly hydrostatic testing and conventional destructive testing for grade determination and MAOP validation. Additionally ABIS performs direct deterministic assessments of anomalies found during ILI runs and new construction validation.
ABIS nondestructively provides the key mechanical properties (tensile and fracture toughness) of your pipeline using our Stress-Strain Microprobe® (SSM) system. The SSM utilizes the Automated Ball Indentation® (ABI® ) test technique. ABI® testing is performed in a nondestructive localized fashion without any interruption to the pipeline transmission service. The in-situ ABI® -measured yield and ultimate tensile strength values are used to determine the Grade of the pipeline based on the minimum requirements of the API 5L Specification for the YS and UTS values of each pipe grade.
The integration of the SSM measurements with conventional, non-destructive inspection results (crack/flaw size and/or corrosion pitting profile measurements) allows calculating the maximum safe operating pressure and the determination of replacement or repair of older pipelines. In addition, the quality of seam welds and girth welds in repair jobs or in new pipeline construction (particularly for high strength grades such as X80 through X120) can be quantified thoroughly from their ABI® -measured fracture toughness values and tensile properties (required for a true verification of weld over-match that is mandated for the strain-based design of arctic or earthquake-prone pipeline applications).
