SPECIALIZED NDT SOLUTIONS

Our Services

Delivering precision inspection across all NDT disciplines. Every method. Every material. Every site. Certified technicians operating at the highest industry standards.

Radiographic Testing (RT)

Conventional and reliable radiography with on-site digital capture.

MPIA delivers conventional, reliable Radiographic Testing with on-site digital capturing for real-time results access. We operate specialized mobile units, Iridium-192 sources, and digital workflows to give rail and industrial sites same-day inspection outcomes.

Technical Specifications

Applicable StandardsTFR BBB Specification, ASME B31.3, SNT-TC-1A Level III Certifications
Professional EquipmentIr-192 Gamma Sources, Digital Capture Systems, Mobile Field Units, 100XD Film
Conventional reliable RT
On-site digital capture (real-time results)
Thermit weld inspection

Rail running surface
Weld integrity mapping
Wall thickness measurement
Sub-surface flaws

Magnetic Particle (MT)

Surface and near-surface defect detection in ferromagnetic components.

Identifying fatigue cracks and material separations using electromagnetic fields. Critical for rail head surface integrity and wheel flange inspection in heavy-haul environments.

Technical Specifications

Applicable StandardsSANS 3577-3, ASTM E709
Professional EquipmentMagnaflux Yokes, UV Lamps, Fluorescent Particle Systems
Rail head crack detection
Wheelset inspection
