may vary in quite a wide range depending on the composition of the material, technology of extrusion, manufacturer, etc, from the present video it's possible to realize that it's lower than the velocity in rexolite wedge

it is possible, simply contact support@sonotronndt.com for all technical questions

which kind of certificate?

hard ceramic contact face single element probe 5 MHz 10 mm crystal dia

Scanning is performed above the taper surface and of course the probe profile should allow the scanning in case of limited room - see for example here: ua-cam.com/video/foZTotzIo4E/v-deo.html The scanner supports probes having different profiles of probes and flanges

Okay ,

Sonotron NDT is the manufacturer of ultrasonic testing equipment, not the inspection company, the video was captured by one of our customers (Inspection Company) some few years ago. So we may just guess now and your explanation is very reasonable - depending on the OD and vertical position of the pipe, another video with unusual position of the start point is here: ua-cam.com/video/9dlULlb2AEY/v-deo.html

不，这不是 PA；单元件 SRUT GW 探头正在使用中

this is so called CB-Scan: short range guided wave propagates in the pipe wall in circumferential direction (around the pipe) so the probe with contoured contact face located in the position ~12 o'clock is capable to receive echoes from the imperfections distributed along whole circumference including pipe support / saddle area, for example between 4 and 8 o'clock

Thanks to 100% A-Scan capturing and returning to the ground: depending on probe(s) and probe(s) holder used used this may be pulse echo flaw detection, pitch-catch probing, TOFD, etc

These are not the EDM notches

The RF A-Scan is the natural form of ultrasonic signals, the raw data RF A-Scans have been carried to the computer on the ground; the automatic coupling monitoring has been performed for each touch through analyzing the series of back echoes

@@sonotronndt but why not full, or half wave negative? Is there a particular reason to use RF? I only ever seen it being used in guided wav.

@Karmav3 RF A-Scans carry much more information and they are used very widely for plenty of inspections, not for the Guided Wave inspection only. For the thickness gauging tasks the RF A-Scans may be very useful as well. The operator may toggle between RF / Rectified (Full, Po, Neg) A-Scans in the regular flaw detectors and advanced thickness gauges and the same toggling is provided for the drone-based inspection

yes, SRUT is the screening technology widely used for the detection of corrosion damages under pipe support (CUPS) since 1999 with involving Sonotron NDT SRUT GW probes and ISONIC series instruments

This plate is a piece of real annular ring. Once the corrosion was found - it was extracted from the asset and the artificial reflectors were added to the natural in order to compare the detectability. THe sample is about 20 y.o. Here you may see postprocessing of SRUT GW data recorded on the sample using ISONIC 3505: ua-cam.com/video/qbK9hAh_WSs/v-deo.html - it is self-explaining - all real corrosion defects were found successfully including those, which are located behind large artificial reflectors, it is just necessary to record the data over wide dynamic range. And here is another example for data interpretation - this is complimentary shear wave true-to-geometry multi-skip S-Scan record ua-cam.com/video/Af5vr1V8nCg/v-deo.html - just natural defects

No, just regular rexolite wedge

USONIC 2010 is a wrong name, the correct name is ISONIC 2010

Thx a lot

What is channel.. how we explain??

Usually the newly manufactured fillet weld connecting shell to annular ring should be inspected for no leaks ( impenetrability ) only Whilst in-service - the weld metal loss from inner side of the tank should be detected, this is possible with the use of A-Ring shown in the present video. And you may see this defect - ultrasonic and actual image here: ua-cam.com/video/Af5vr1V8nCg/v-deo.html

this is a sample full penetration fillet weld with natural defect; the sample was received from the user, the same SW option is applicable to the T joint but weld

Thanks for the question There are many factors influencing on the attenuation such as pure attenuation of the plate material, lining at the soil and product side, product itself. To consider all factors the appropriate test blocks should be manufactured prior going out to the field and the settings should be adopted accordingly. The videos below illustrate pre-inspection trials for such inspection using conventional modality Block prior to the lining ua-cam.com/video/t7i_g_gSYyI/v-deo.html The same block upon lining completed (the lining should be of the same type / material that is used in the real tank ua-cam.com/video/ACb2bAQulLw/v-deo.html Influence of the product above the plate ua-cam.com/video/2N6QCu3N8L8/v-deo.html All factors above do damp the signal significantly or even dramatically but in case of finding dB/mm signal degrade factor and creating the appropriate DAC it is possible to utilize Normaliz-To-DAC imaging function and compensate such influence The same approach works for PA modality as well

Hi and thanks for the comment The indications you're speaking about are caused by the reflections situated not "before the fillet weld" as it is noted in your message but right under the tank shell, these are typical indications for the scattered corrosion in the said area that were observed for quite a large number of tanks either resting on the concrete ring or not. The conclusion about the scattered corrosion has been confirmed then at the stage of repair works for the sufficient quantity of the tanks. Also the TOF-based polygon measurements and cross sectional FMC/TFM image shown in the video clearly show the tips on the corroded surface located significantly far from the surface than 1..2 mm noted in the message

@@sonotronndt thanks for your prompt reply..In my first message when i said that "we were getting some reflections before the fillet weld" was based on the A- scan signals and yes its clearly seen from the B-scan that those indications are from under shell. Previously when such indications were observed from under the shell, the TOF of the tip signals were used as well to gauge the remaining wall thickness, based on the nominal wall thickness which our clients would provide...The measurement mostly leads to only oversizing. For example we were inspecting a 16mm thick annular plate, we got a similar indication from under shell as shown in the video..Based on TOF of tip signals the remaining wall thickness at the so called corroded zone based on PAUT was measured to be around 12 to 12.5mm, that area was excavated to do a Zero degree UT measurements and thickness measured would vary between 14.9 to 15.6mm, which means PAUT oversized by 2 to 3mm...Can the TFM algorithm reduce this oversizing?

The deviation of TOF measurements from the real values may be reduced significantly provided the EquPAS approach applied whilst performing shear wave S-Scan coverage - see for example the video here: ua-cam.com/video/7GJCwRicdBg/v-deo.html illustrating the use of DAC normalization along with AGC (Angle Gain Compensation). The results of the evaluation using S-Scan with EquPAS approach and FMC/TFM are practically the same and they are more precise comparing to the regular S-Scan evaluation

In the same manner as on other metals - optimizing the signal through appropriate pulser / receiver settings in order to obtain backwall echoes consistently within entire material thickness range to be evaluated then settling ultrasound velocity in the material
