Quality Assurance & Testing
Every pipe manufactured in our facility undergoes a rigorous 5-point inspection process to ensure zero-defect delivery.
- Hydrostatic Testing: Verification of leak-proof performance under high pressure.
- Eddy Current Test: Non-destructive identification of surface and sub-surface flaws.
- Chemical Analysis: Positive Material Identification (PMI) to verify alloy composition.
- Mechanical Testing: Tensile, Yield, and Elongation testing as per ASTM codes.
