Non-Destructive Testing (NDT)
Non-destructive testing services that detect flaws in materials and welds in industrial facilities, pipelines and power plants without causing any damage.
Radiographic Testing
A method in which X-rays or gamma rays are used to image internal voids, thickness and density variations of a material on a radiation-sensitive film.
Ultrasonic Testing
A non-destructive testing method that determines the location, size and type of discontinuities by making use of the reflections of high-frequency sound waves within the material.
Magnetic Particle Testing
A method based on the principle of inducing a magnetic field in the test piece, used to detect surface defects in ferromagnetic materials.
Penetrant Testing
The most widely used non-destructive testing method, in which surface-breaking defects are detected with a visible or fluorescent dye solution.
Visual Testing
The oldest and most widely used NDT method, in which imperfections and discontinuities on the material surface are examined with the naked eye or with auxiliary equipment.
Eddy Current Testing
An inspection method performed on conductive materials by means of the alternating magnetic field generated by a test coil and the eddy currents it induces in the material.
Positive Material Identification (PMI)
A method in which the characteristic radiation released from atoms under X-ray excitation is measured to characterise the material both quantitatively and qualitatively.
Ferrite Content Measurement
A measurement carried out to guarantee the ferrite content of the final product after welded fabrication of austenitic, duplex and super duplex materials.
Leak and Pressure Testing
A test method used to detect defects likely to occur in tank bottom plates and in their butt and fillet welds.
Advanced Non-Destructive Testing
High-precision, imaging-based and fast NDT using advanced technologies such as Phased Array, TOFD, digital radiography, corrosion mapping and crawler systems.
Phased Array (Phased Array UT)
Three-dimensional inspection and imaged reporting of welded or unwelded structures; the ability to sweep, focus and image in real time across all angles.
ToFD (Time of Flight Diffraction)
An ultrasonic method that tests weld seams and critical areas with high accuracy, involves no radiation hazard and provides reliable flaw sizing.
Digital Radiographic Testing
High-resolution digital radiography with reusable imaging plates, used to detect flaws, cracks, corrosion, erosion and wall thickness loss.
Corrosion Mapping
Reliable inspection of pressure vessels, tanks and pipelines through ultrasonic corrosion mapping that covers the entire area instead of localised spot checks.
Pipeline Inspection with Crawlers
Crawler units that provide fast internal inspection of 16"-60" diameter pipes by producing a panoramic image of the weld seam in a single exposure.
Rope Access Non-Destructive Testing
NDT services carried out with the rope access method, which is far faster, more economical and safer than scaffolding in hard-to-reach and high structures.
Destructive Testing (DT)
Accredited laboratory tests that determine the mechanical and metallurgical properties of metallic materials and welded joints on specimens.
Tensile Testing
Determination of yield/tensile strength and elongation values of metallic materials and welded joints under static load.
Guided Bend Test
Determination of a material's ability to undergo plastic deformation under bending load; root, face and side bend testing on welds.
Notched Bar Impact Test (Charpy)
Determination of a material's fracture energy under dynamic loading at a specified temperature and evaluation of the fracture type.
Nick-Break Test
Visual evaluation of internal defects in the weld cross-section by fracturing the weld specimen from a machined notch.
Fracture (Break) Test
Examination of internal defects (porosity, cracks, lack of fusion/penetration) by fracturing welded joint specimens through the weld metal.
Flattening Test on Tubes
Determination of plastic deformation capability by compressing specimens cut from tubes to a specified degree of flattening.
Hardness Testing
Measurement of the resistance a material offers to a harder indenter pressed into its surface (Vickers).
Macro Analysis / Examination
Examination of the specimen with the unaided eye or at magnifications up to 50X to evaluate the weld cross-section, penetration and discontinuities.
Micro Analysis / Examination
Examination of the internal structure of the specimen (grain structure, phase precipitation) at magnifications of 50–500X.
Chemical Analysis by Optical Emission Spectrometry
Determination of the chemical composition (elements and their quantities) of metallic materials by optical emission spectrometry.
Z Quality Test
Determination of the Z (through-thickness) quality of a specimen by pulling it in the thickness direction and measuring the reduction of area at the fracture.
Metallographic Replica Testing
Taking an exact three-dimensional copy of a surface in the field so that the microstructure can be examined in the laboratory.
Corrosion Testing
Comprehensive corrosion testing for stainless steels, alloys and coatings, including intergranular corrosion, pitting, salt spray/CASS and detrimental phase detection.
Microhardness Testing
Determination of the hardness distribution of thin sections, coatings and welded regions by Vickers microhardness measurement under low loads.
Surface Roughness Testing
Verification of specification compliance by measuring the roughness parameters (Ra, Rz) of machined and prepared surfaces.
Peel Test (for Resistance and Spot Welds)
Evaluation of weld nugget size and quality by peeling resistance/spot welded joints apart.
Chisel Test (for Resistance and Spot Welds)
Assessment of weld integrity and nugget quality of spot welds in the field or laboratory by forcing a chisel into the joint.
Stripping (Peel) Test (for Resistance and Spot Welds)
Determination of weld strength by pulling spot/projection welded specimens in the shear direction.
Pressure Test (for Resistance and Spot Welds)
