Why You're Still A Rookie In Ultrasonic Transducers
The detected data are processed by computer to print out all defect reports, data of serious defects excavation and manuals of pipelines, which facilitate the maintenance of pipes and fully demonstrate the advanced and superior technical performance of ultrasonic transducer for distance pipeline corrosion detectors. Application of the problems and solutions pipeline ultrasonic detector pipeline automatic detection, although there are many advantages, but there are also some limitations. Enumerated two kinds of defects, one is a shallow pit, because of its area is usually smaller than the area of the piezoelectric ultrasonic distance measuring transducer ; the other is a shallow shelf-shaped or ladder-shaped defects, an area from 0.32 ~ 6.45 cm2 range, the use of ultrasonic probe on the corrosion area of pipelines and corrosion detection, often error.
ultrasonic detectors for pipeline corrosion prediction and pipeline maintenance is very important. In the United States, the use of pipe ultrasonic detectors to predict pipeline corrosion accidents has become legalized. With the development of automation technology, ultrasonic transducer for 8 meter distance measurement testing technology will also continue to improve and improve, and presents the following trends.
(1) The detection system further tends to be automated and intelligent.
(2) Detection technology tends to diversify. At present, in the pipeline 3 meter ultrasonic distance measuring transducer, piezoelectric ultrasonic still dominates, the technology is relatively mature, but also exposed some problems. As a non-contact detection of electromagnetic ultrasonic and laser ultrasonic detection technology will get greater development. (3) The use of advanced data processing methods to make up for the shortcomings of the ultrasonic detection technology itself, the data processing results more diverse.
(4) The test will develop towards high precision and be suitable for different work environments. (5) Ultrasonic testing will be combined with fracture mechanics to evaluate the life of the pipe
