Services

1. Non-Destructive Testing (NDT)

We deliver comprehensive NDT services to assess the integrity of materials, equipment, and structures without causing damage. Our qualified inspectors use internationally recognized methods to ensure compliance with industry standards and support safe, reliable operations.

1.1 Conventional NDT

    • Radiographic Testing (RT):
      Uses X-rays or gamma rays to detect internal defects in welds and materials.
    • Ultrasonic Testing (UT):
      Employs high-frequency sound waves to identify internal discontinuities and measure material thickness.
    • Magnetic Particle Testing (MT):
      Detects surface and near-surface flaws in ferromagnetic materials.
    • Penetrant Testing (PT):
      Reveals surface-breaking defects in non-porous materials using liquid penetrants.
    • Visual Testing (VT):
      Performs detailed visual inspections to identify visible defects, damage, or non-conformities.

1.2 Advanced NDT

    • Magnetic Flux Leakage (MFL):
      Inspects storage tanks and ferromagnetic structures for corrosion and metal loss.
    • Long Range Ultrasonic Testing (LRUT):
      Examines long sections of piping from a single test location, minimizing the need for insulation removal.
    • Internal Rotary Inspection System (IRIS):
      Provides highly accurate ultrasonic inspection of heat exchanger and boiler tubes.
    • Phased Array Ultrasonic Testing (PAUT):
      Uses electronically controlled ultrasonic beams to deliver high-resolution imaging and advanced weld inspections.
    • Time of Flight Diffraction (TOFD):
      Accurately detects and sizes weld defects using diffracted ultrasonic waves.

1.3 Cathodic Protection Surveys (CIPS/DCVG)

    • Close Interval Potential Survey (CIPS):
      Evaluates the performance and effectiveness of cathodic protection systems along buried pipelines by measuring pipe-to-soil potentials at closely spaced intervals.
    • Direct Current Voltage Gradient (DCVG):
      Identifies and locates coating defects, holidays, and areas of corrosion risk on buried pipelines by measuring voltage gradients in the surrounding soil.

These complementary techniques provide accurate assessment of pipeline coating integrity and cathodic protection performance, enabling early detection of defects and supporting effective integrity management programs.
