Applicable Pipe Envelope, Materials & Defect Matrix
Material Compatibility
Carbon steels, alloy steels (Cr-Mo grades), stainless steels, and nickel-based corrosion-resistant alloys (CRAs).
Detectable Defect Matrix
Surface Flaws: External and internal cracks, seams, laps, slivers, and scabs.
Volumetric Flaws: Inclusions, porosity, and lack of fusion in weld lines.
Dimensional Deviations: Wall thinning, eccentricity, and out-of-roundness.
Calibration, Quality Control & Traceability
Mill compliance requires verifiable, repeatable calibration routines before every production shift.
Reference Standards (Cal Standards):
Automated insertion of artificial calibration standards, including EDM notches and drilled holes matching specific API and ASTM depth and width tolerances.
Data Traceability:
Every tested pipe generates a time-stamped inspection log containing C-scan/D-scan imaging, geometric profiles, and Pass/Fail status linked via barcode or RFID tracking.
Shop Floor Quality Control:
Internal machining centers utilize laser interferometers to calibrate probe holder positioning, ensuring mechanical alignment tolerances stay under 0.02 mm prior to dispatch.
