Our Services
WHAT WE OFFER
A full range of NDT, inspection, and engineering support services delivered by an experienced technical team.
🔍 NDT Services
OUR CORE COMPETENCY
Non-Destructive Testing is the foundation of Helibat Engineering Services. We offer a comprehensive range of both conventional and advanced NDT methods, applied across oil & gas, refining, petrochemical, power, and fabrication sectors.
Conventional NDT Methods
UT — Ultrasonic Testing
Wall thickness measurement, weld scanning, flaw detection in plates, pipes, and pressure vessels.
RT — Radiographic Testing
Weld quality and internal defect detection using X-ray or gamma-ray on piping, vessels, and structures.
MT — Magnetic Particle Testing
Surface and near-surface crack detection on ferromagnetic welds, castings, and structural members.
PT — Liquid Penetrant Testing
Surface-breaking defect detection on any non-porous metallic or non-metallic material.
LT — Leak Testing
Pressure, vacuum, and bubble leak testing for vessel and piping integrity verification.
VT — Visual Testing
Structured visual inspection per ICP/QA/QC requirements, pre- and post-weld examination.
Advanced NDT Methods
PAUT — Phased Array UT
Multi-beam UT for complex weld geometries, nozzles, and corrosion mapping on pressure vessels.
TOFD — Time of Flight Diffraction
High-accuracy weld flaw sizing and depth measurement, particularly for heavy-wall components.
MFL — Magnetic Flux Leakage
Corrosion and metal loss detection in API 653 storage tank floors and pipeline systems.
DCM — Digital Corrosion Mapping
Automated encoded UT scanning for detailed corrosion pattern analysis on vessels, tanks, and piping.
IR — Infrared Thermography
Thermal imaging for insulation condition, electrical systems, and refractory lining inspection.
AE — Acoustic Emission Testing
Structural integrity monitoring of pressure vessels and tanks under operating or test load conditions.
