Since our establishment in 2006, we have remained committed to delivering high-quality inspection solutions that ensure the safety, reliability, and compliance of industrial assets, without causing damage or interruption to operations. Our NDT services are designed to help industries detect flaws, verify integrity, and maintain compliance with national and international standards. From oil and gas to construction and power generation, we support our clients with precise, professional, and timely inspection services.

Our Conventional NDT Services

We offer a full range of conventional NDT services that are widely accepted and required across many industries. Our certified and experienced technicians perform inspections using the latest equipment and in compliance with ISO and API standards.

Radiographic Testing (RT)

We inspect the internal structure of welds and castings to reveal hidden defects. Our radiographic inspection is available in film using X-rays, Ir-192, and gamma rays.

Ultrasonic Testing (UT)

We work with high and low-frequency sound waves to identify internal flaws and check material thickness. UT is ideal for welds, pipelines, tanks, and structural components.

Liquid Penetrant Testing (PT)

We apply visible or fluorescent dyes to reveal cracks, porosity, or pinholes on the surface of non-porous materials. It’s a fast and cost-effective method for surface inspection.

Magnetic Particle Testing (MT)

This technique is used to find surface and slightly subsurface discontinuities in ferromagnetic materials. It’s commonly applied to welds, forgings, and pipelines.

Visual Testing (VT)

Our team performs direct and remote visual inspections to identify surface flaws, weld defects, and general deterioration. Visual testing is often the first line of defense in quality assurance.

Radiographic Film Interpretation (RFI)

Involves expert analysis of radiographic images to accurately interpret discontinuities and confirm code compliance.

Ultrasonic Thickness Gauging (UTG)

A precise method to measure the remaining wall thickness of metal structures, commonly used in corrosion monitoring and maintenance planning.

Vacuum Tube Leak Testing

A technique used to detect leaks in condenser tubes, boilers, and heat exchangers, particularly during shutdowns or maintenance.

Post Weld Heat Treatment (PWHT)

Heat treatment conducted after welding to relieve residual stresses, reduce hardness, and improve the toughness of the weldment.

Portable Hardness Testing

Onsite testing of metals to determine hardness levels, ensuring compliance with mechanical property requirements.

Positive Material Identification (XRF and Spectro)

Performed using X-Ray Fluorescence (XRF) or Optical Emission Spectrometry (OES) to verify material composition and ensure correct alloy usage.

Ferrite Content Inspection

Measures ferrite percentage in stainless steel welds to assess mechanical strength and corrosion resistance, especially important in high-temperature or corrosive environments.
