Non Desctructive Testing
Non–Destructive Testing (NDT) is a vital technique used to assess the integrity of materials,
components, and structures without causing any damage. It plays a critical role in ensuring
operational safety and minimizing equipment failure across industries. Unlike Destructive
Testing, which involves breaking or altering a component to evaluate its properties, NDT
preserves the asset while identifying internal flaws, cracks, or irregularities. This makes it ideal
for in–service inspections, quality control and preventive maintenance.
We offer a wide range of advanced NDT services designed to meet international standards and
the demanding needs of industries such as oil & gas, construction, and manufacturing. Our
certified ndt technicians bring both precision and field expertise
Ultrasonic Testing (UT) is a reliable method used to detect internal flaws and measure material thickness without damaging the component. In Ultrasonic Testing , high–frequency sound waves are transmitted into the material and reflections from any discontinuities are recorded by a sensor. This technique is widely used in welding inspections, corrosion monitoring and thickness gauging. UT offers high accuracy and is effective for both metallic and non–metallic materials.
Dye Penetrant Testing (DPT), also known as Liquid Penetrant Testing (LPT), is a surface inspection method that is used to identify cracks, porosity, or other surface–breaking flaws in non–porous materials. A visible or fluorescent dye is applied to the surface, which seeps into any discontinuities. After a developer is applied, flaws become visible. This method is cost–effective and suitable for metals, ceramics, and plastics.
Radiographic Testing (RT) uses X–rays or gamma rays to capture images of a material’s internal structure. The radiation passes through the component and exposes a film or digital detector. It reveals hidden defects like voids, inclusions or cracks. Radiographic Testing is widely used in pipeline welding, pressure vessels and structural components. It provides a permanent visual record of internal conditions without altering the tested object.
Eddy Current Testing (ECT) is a fast and accurate method that is used to detect surface and near–surface flaws in conductive materials. It works by inducing electrical currents (eddy currents) in the material using an alternating magnetic field. Changes in these currents indicate defects or material inconsistencies. Eddy Current Testing is useful for crack detection, conductivity testing, and coating thickness measurement.
Thickness Gauging is used to measure the wall thickness of materials, especially in corrosion monitoring and quality assurance processes. Ultrasonic or mechanical gauges are used to take accurate measurements without cutting or damaging the material. This method is crucial for maintaining minimum thickness requirements in pipelines, tanks, and structural components. It ensures safety, performance and regulatory compliance across industries like oil & gas and
manufacturing.
Hardness Testing measures a material’s resistance to deformation by applying a specific load through a hardened indenter. The depth or size of the resulting impression is used to determine hardness levels. This method helps assess wear resistance, strength, and durability. It is commonly used for metals and welds in construction, automotive, and manufacturing sectors to verify material suitability for service conditions.
Positive Material Identification (PMI) is used to verify the chemical composition of metals and alloys. Using techniques like X–ray fluorescence or Optical Emission Spectrometry, PMI ensures that materials meet required specifications. It is crucial for quality control in industries where material mix–ups can lead to serious failures, such as oil & gas, petrochemical, and power generation. PMI supports traceability and compliance with industry standards.
Ferrite Testing measures the amount of delta ferrite in stainless steel welds or components to assess their mechanical and corrosion resistance properties. Maintaining the correct ferrite content is essential to prevent cracking and ensure long–term durability, especially in high-temperature or corrosive environments. This test is widely used in the fabrication of pressure vessels, piping systems, and other critical components in the chemical and energy sectors.
Holiday Testing is performed to detect pinholes, cracks or coating defects on non–conductive protective layers applied to conductive substrates like steel. A voltage is applied across the surface, and any flaws in the coating allow current to pass through, triggering an alarm. This method is essential in pipeline and storage tank coating inspections to ensure corrosion resistance and long–term protection against environmental damage.
Infrared Thermography detects thermal inefficiencies by capturing heat signatures from a surface using an infrared camera. It identifies issues such as overheating components, insulation failures, electrical faults, or hidden moisture without physical contact. This non–invasive method is widely used in building inspections, electrical systems, and mechanical equipment monitoring, providing real–time diagnostics and preventive maintenance insights with minimal disruption.
