Testing

Our Testing Capabilities

Every product undergoes mandatory testing before leaving our facility

Ultrasonic Testing (UT)

Detects internal flaws, cracks and inclusions in pipes, bars and plates using high-frequency ultrasonic waves per ASTM E213.

Hydrostatic Testing

Pressure testing of all pipes and spools under water pressure to ensure leak-tightness and structural integrity per ASME.

Hardness Testing

Brinell (BHN) and Rockwell (HRC) hardness verification per ASTM E18/E10 to confirm heat treatment compliance.

PMI — Positive Material Identification

XRF-based PMI testing confirms exact alloy composition, preventing mix-up of grades at source and during fabrication.

Dimensional Inspection

OD, WT, length, ovality and straightness checked per ASTM / DIN / EN tolerances using calibrated instruments.

Chemical Analysis

Spectrometric chemical composition check ensures ASTM, EN, DIN grade specification compliance for each heat/lot.

Tensile / Mechanical Testing

UTS, Yield Strength, Elongation per ASTM A370 — confirms product meets the mechanical properties of the specification.

Impact Testing (Charpy)

Charpy V-Notch impact testing at sub-zero temperatures for low-temperature service applications per ASTM A370.

Visual & Surface Inspection

100% visual check for seams, pits, scales and surface defects. Finished surface roughness measured for polished grades.
