Non-Destructive Testing (NDT)

NDT is a testing method used to identify and evaluate the condition of material without destroying it. It is an essential part of asset integrity management as it can improve reliability, prevent failure, reduce shutdowns and maximise production and profits.

Who performs non-destructive testing?

Who performs non-destructive testing?

For NDT to work effectively, practitioners must have a comprehensive knowledge of the range of techniques available, when they should be used, what they can detect and their limitations. All NDT needs to be applied under the control of a procedure that is created and approved by a competent person with relevant experience and appropriate qualification(s).

To complement our NDT services we can also certify welders and weld procedures to both European and American standards in accordance with applicable regulatory requirements.

Ultrasonic Testing

Used to provide measurements of wall thickness through the application of high frequency sound. It is also used to detect defects, cracks, voids and inclusions in welds, pressure vessels castings, aircraft, structural steelwork and more.

X-Ray and Gamma Radiation

Used to detect hidden flaws in materials, solid objects and fabrications. Radiography is most suitable for volumetric defects such as slag and porosity and finding voids, solid inclusions and gas pores.

Magnetic Particle Examination

Used to detect discontinuities of the surface, or near surface, in ferromagnetic materials such as iron and steel. This technique detects flaws not visible to the eye, as well as sub-surface flaws. It is also the preferred method for examining surface cracks in ferritic material.

Dye Penetrant Examination

Used to detect flaws in non-ferromagnetic materials. Some of the most common materials covered by this test are forged, cast or welded products. It is the preferred method for detecting flaws in non-magnetic materials and is most suitable for the detection of volumetric defects such as pits.

Hardness Testing

Measures the resistance to scratching, cutting, indentation and bending of a material. This test covers everything from aluminium alloys to stainless steel

Ferrite Testing

Measures duplex and austenitic stainless steel, welding and piping for ferrite content. Ferrite Testing is an essential element in preventing the reduction of a material’s service life.

Lighting Column Inspection

Aims to detect the corrosion of steel columns that cannot otherwise be identified by visual inspection. The test takes place above and below ground and can outline any internal corrosion of the base and the hot-swaged joint.

Thickness Checking

Corrosion measurement and monitoring consists of a range of NDT techniques, such as ultrasonic testing, radiography, thermography, etc. Its aim is to determine how corrosive an environment is in order to optimise the control and prevention methods of an organisation.

Eddy Current Testing

Used in the examination of heat exchange tubing. The test is conducted for detecting surface breaking defects in ferromagnetic materials and giving an indication of the depth of a defect in non-magnetic materials.

Positive Material Identification

This method consists of the chemical analysis and identification of metal and alloys in order to determine their chemical composition through non-destructive testing. Usually, this technique is used when working with large parts that cannot be routinely tested

Pressure Testing

Usually performed at the start of a plant or equipment’s life and carried on subsequently. It involves the process of over-pressurisation of an item with a fluid in order to examine whether it is able to withstand the applied stress. When applied alongside acoustic emission, this test can help establish crack growth.

Used to observe the temperature of the surface of an item through an infrared camera or monitor. Through this test, it is possible to determine any wall thinning, build up of scale, or the presence of wet insulation. The test is also applicable to containers consisting of either hot or cold liquid, allowing a non-invasive observation of the level of the liquid.
