About Us
Non-destructive testing (NDT) services involve evaluating materials, components, or systems for defects without causing any damage to the original object. These services are critical for maintaining safety and structural integrity in industries like oil and gas, aerospace, construction, and manufacturing.
Core NDT Methods
Most service providers offer a mix of conventional and advanced techniques:
* Visual Testing (VT): Direct or remote inspection using the naked eye, borescopes, or drones to find surface flaws.
* Ultrasonic Testing (UT): Uses high-frequency sound waves to detect internal flaws and measure material thickness.
* Radiographic Testing (RT): Employs X-rays or gamma rays to view the internal structure of welds and components.
* Magnetic Particle Testing (MT/MPI): Identifies surface and near-surface defects in ferromagnetic materials using magnetic fields.
* Liquid Penetrant Testing (PT/LPI): Uses a visible or fluorescent dye to reveal surface-breaking cracks in non-porous materials.
* Eddy Current Testing (ET): Uses electromagnetic induction to detect cracks and corrosion in conductive materials.
Advanced NDT Techniques
For complex geometries or higher precision, specialized services include:
* Phased Array Ultrasonic Testing (PAUT): An advanced UT method that uses multiple elements to steer sound beams for faster, more detailed imaging.
* Time of Flight Diffraction (TOFD): A highly accurate method for sizing and locating weld defects.
* Digital/Computed Radiography: Modern alternatives to film that provide instant, high-resolution digital images.
* Positive Material Identification (PMI): Verifies the chemical composition of alloys and metals.
Our sales of NDT consumables offer high contrast quality films for the purpose of radiography and x-rays services.
