Non-destructive testing of new technology and old technology is relatively conventional, traditional conventional detection technology if it can give new content can be called new. Ultrasonic, radiographic, eddy current and so is the traditional detection methods, but with the physical, mechanical, electronics, materials science and computer technology, sensors / transducers, signal processing technology, defect recognition technology development and integration, are continuously being new development and application.
Currently, non-destructive testing of new technology are: electrostatic sensor technology, air-coupled sensor method, electromagnetic acoustic transducer method, a laser ultrasonic method, optical holography or interferometry, magnetostrictive sensor method, hybrid ultrasonic technology, this paper briefly a few kind of the more popular non-destructive testing new technologies.
Industrial pipe endoscopy, non-destructive testing tools as a category in the pipeline maintenance plays an important role. Pipe defect size and defect characteristics for more precise quantitative judgments on the non-destructive testing requirements are also increasing. Industrial endoscopes and other non-destructive testing diagnostic methods more and more attention, which aims to ensure that the equipment is not in use before the serious deficiencies and meet the quality requirements; during use regular testing, the aim is to discover whether the newborn during use defects in a timely manner to remind the user of the equipment for maintenance.
NDT Applications:
1, car inspection engine, hydraulic parts, nozzle part quality inspection and assembly testing.
2, industrial endoscope mechanical inspection, boilers, heat exchangers, mechanical equipment and manufacturing equipment.
3, rail, ship inspection turbines, heaters, engine, boiler flame pipe inspection.
4, electronics, electrical industrial machinery operation inspection, parts inspection, and research and development fields.
5, petrochemical process configuration of piping, pressure vessels, boilers, heat exchangers and other equipment checks.
6, steel equipment repair and maintenance, but also the quality of products for pipe inspection.
