Conventional Ndt
An extremely cost effective method for detection of surface and near surface flaws in ferromagnetic materials, is primarily used for crack detection. Following magnetisation the specimen is covered with very fine iron particles either dry or suspended in liquid. …..
A low cost method of detecting surface breaking flaws, such as crack, cold laps,porosity etc.The dye penetrant is drawn in the surface breaking flaw by capillary action and the excess surface penetrant is removed, a developer is applied to …..
Radiography testing (RT) is the method of inspecting materials for hidden flaws by using the capability of short wavelength electromagnetic radiation , X-rays and gamma rays radiation to penetrate various materials. Gamma rays radiation sources, most commonly iridium-192 and …..
Ultrasonic testing is the NDT method that uses beams of mechanical waves (vibration) of short wavelength and high frequency transmitted from a small probe in contact with the specimen surface and detected by the same or other probe . …..
Eddy current testing is a non-destructive method used for a variety of purposes, including flaw detection,material and coating thickness measurements, material identification and establishing the heat treatment condition of certain materials. Eddy current uses the principle of electromagnetic induction …..
Ultrasonic Wall thickness meters are used for wall thickness measurements. This is done to check the thickness of pressure vessels, storage tanks etc…By taking wall thickness measurements, it can tell you if the vessel has corrosion and you can …..
Ultrasonic Phased array testing (PAUT) is an advanced non-destructive examination technique that utilises a set of ultrasonic (UT) probes made up of numerous small elements, each of which is pulsed /phased individually with computer calculated timing . These techniques …..
The system utilises the proven reliability of the scorpion wall crawler with an added transverse scanner fitted to the front end. The scanner covers a 130mm wide strip at the speed 600mm/sec. The adjustable scanning head allows inspection of …..
The floor map uses the magnetic flux leakage technique to detect surface and bottom side corrosion on above ground storage tank floors to provide a reliable indication of the floor condition within an economical time frame. The test can …..
Vacuum box testing is a non-destructive examination used when trying to locate weld seam leaks . A vacuum box and a compressor create a high or low pressure vacuum while a detergent solution is applied to the test area. …..
Heat treatment of steels and other suitable metals involves the heating of the items to specific temperatures where desired metallurgical changes to microstructure takes place . These temperatures can range from as low as 250°C on temper hardened steels …..
Automated spark testing has been developed to remove the reliance upon operator skill and experience thereby increasing reliability. The system relies upon spectroscopy, spectrometry and other methods to” observe” the spark pattern. It has been found that this system …..
