Description
Technical field
The present invention relates to the technical fields of non-destructive testing, more specifically, it relates to a kind of pipe for adapting to different zones
Road lossless detection method and system.
Background technique
Non-destructive testing, which refers to, not to be damaged or is not influencing detected object service performance, does not injure group inside detected object
Under the premise of knitting, using material internal structure exception or defect there are the variation of the reactions such as caused heat, sound, light, electricity, magnetic, with
Be either physically or chemically means, by up to date technics and equipment and material, to the structure of test specimen inside and surface, property,
The method that the type of state and defect, property, quantity, shape, position, size, distribution and its variation are checked and tested.Nothing
Damage detection is the essential effective tool of industrial development, reflects a national Industry Development Level to a certain extent,
The importance of non-destructive testing has gained public acceptance, and mainly has radioscopy (RT), ultrasound detection (UT), Magnetic testing (MT) and liquid
Four kinds of Liquid penetrant testing (PT).
Ultrasonic Nondestructive is the depths of metal material to be penetrated using ultrasound, and enter another section by a section
When, a kind of method of part defect is checked the characteristics of interface edge reflects, when ultrasonic beam from piece surface by visiting
Head passes to metal inside, and back wave just occurs respectively when encountering defect and part bottom surface, forms impulse waveform, root on fluorescent screen
Defective locations and size are judged according to these impulse waveforms.Common Ultrasonic Nondestructive instrument is that A type shows pulse-echo
Formula supersonic detector, according to the time interval, anti-for reflecting the presence or absence of signal, reflection signal and incoming signal on instrument oscillography screen
Penetrate the height of signal, it may be determined that the presence or absence of reflecting surface, its position and relative size.
A type shows that pulse reflection supersonic detector generally comprises probe and instrument oscillography screen, is using the equipment instrument
When device, staff is pressed probe on workpiece for measurement with hand, is then slowly moved on workpiece for measurement surface, passes through spy
Whether head, which is sent data on instrument oscillography screen, is shown, judge defective on workpiece for measurement.
But state in use supersonic detector detection pipeline when, since pipeline needs to detect the number of peripheral surface
According to will receive the limitation in space in such a way that manpower presses probe detection, so that detection efficiency is low.
