Execution Methodology
Engineering Material Take-Off (MTO) and specification verification against client data sheets.
Approved mill sourcing and pre-order quality alignment meeting project AML (Approved Manufacturer List).
Receipt inspection in Qatar: visual, dimensional, wall thickness ultrasonic gauging, and marking checks.
Positive Material Identification (PMI) using calibrated XRF analyzers to confirm elemental composition.
EN 10204 3.1 Mill Test Certificate (MTC) reconciliation against physical pipe heat numbers.
Protected storage, color-coding by metallurgical grade, and scheduled site dispatch with delivery dossiers.
Quality Control & Traceability
Strict heat number preservation, color-coding according to project standards, 100% PMI verification on high alloys, and verification of mechanical test certificates (tensile, impact Charpy V-notch, hardness).
Inspection & Testing Regimes
Visual surface inspection, ultrasonic thickness gauging, hydrotesting at mill verified via MTC, and optional third-party witness inspection (TPI) in Qatar.
