Testing & Inspection Capabilities
✓
Hydrostatic Testing
100% of pipes tested at 1.5× design pressure. Computer-controlled test stations with automatic pressure recording and digital certificates.
✓
Eddy Current Testing (ECT)
ASTM E213 / E426 compliant. Detects surface and near-surface defects in seamless pipe and tubing. 100% coverage on all austenitic grades.
✓
Ultrasonic Testing (UT)
ASTM E213 method for wall thickness measurement and lamination detection. Used for heavy-wall pipe and duplex/nickel alloy grades.
✓
Positive Material Identification (PMI)
Handheld XRF analyzer verifies alloy composition on every pipe. Eliminates material mix-up risk. Results recorded in MTR.
✓
Mechanical Testing
Tensile testing (yield, tensile, elongation), hardness testing (HRB/HRC/HB), flattening test, flaring test, and reverse flattening per ASTM A370/A450.
✓
Intergranular Corrosion Test
ASTM A262 Practice E (Strauss test) for 304L and 316L grades. Verifies resistance to sensitization and intergranular attack after welding.
✓
Ferrite Content (Duplex)
ASTM A923 Method C for duplex and super duplex grades. Ensures correct ferrite-austenite balance (typically 40-60% ferrite).
✓
Dimensional Inspection
OD, wall thickness, length, straightness, and end finish verified per ASTM A999/A1016. Laser measurement systems for precision.
Request Mill Test Certificates
All shipments include EN 10204 Type 3.1 MTR. Type 3.2 with third-party inspection available on request.
