Noncontact
ultrasonic scanner-flaw detector А2075 SoNet is applicable for automatic search of flaws in
the metal pipe’s walls of 720 ÷ 1420 mm in diameter and with thickness starting
from 6mm.
Mainly the instrument is used as a part of flaw
detection sets. Such flaw detection sets are used for searching flaws in gas
pipelines, oil pipelines and products pipe line during major repairs or during
the construction process
The
inspection is conducted by an inline automatic moving of the inspecting part of
a flaw detector along generatrix on the external surface of a pipe. Thanks to
the effect of guided-wave ultrasound propagation in a pipe’s wall, flaw
detection on its full-circle is provided. An image of a pipe’s weep is made
right during the scanning that helps to respond promptly to flaws coming up, to
plot the coordinates, to estimate their type and shape using standard tools of
nondestructive testing.
Features
- Operating principle of the
scanner- flaw detector is a wave guided pulse echo inspection technique
Excitation (sending) and receiving of ultrasonic waves in a pipe’s body is
made without a contact (without using a couplant) with a help of
electro-magnetic acoustic (EMA) transducers.
- Detection of a stress-corrosion
and corrosion flaws in the pipe’s body. Detection of flaws in flats (sheet
products) with indication of flaw’s quantity, relative dimensions and
locations (coordinates).
- Wi-Fi connection between the PC
and the scanner-flaw detector А2075 SoNet provides a
great mobility and the possibility for the operator to conduct testing
remotely.
- An image of a pipe’s weep is
made right during the scanning, that helps to respond promptly to flaws
coming up and helps to decide if an additional inspection with the other
NDT methods is necessary.
- Continuing documentation of the
results as a scanning image of the pipe.
- Efficient review of the
collected scan images in the screen of the Notebook.
- Post-processing of the scan
images along with recording of the location, orientation and the type of
the flaws.
- Time required to set up the
instrument and start inspection is just 3 minutes.
- The possibility to upload the
data from intratubal inspection and attach it to the main report.
- Module design of the instrument
makes it possible to to promptly replace a broken module on-the-site by
only one user of the instrument.
- Portability – the instrument
can be carried by 2 people and can be operated by 1 user.
Capabilities
- Efficiency – up to 7 meters per
minute;
- Sensitivity – detecting surface
longitudinal splits and corrosion from 1mm in depth;
- А2075 SoNet is able to work on the
pipe that has been earlier shelled from the old isolation. The scanner
ensures 100% recurrence of the data.
- The scanner-flaw detector
provides a higher percentage of detectability of stress-corrosion flaw and
delaminations comparing the result of a intratubal flaw-detector.
- Reliability – operating
temperature range from -30° to 50°С;
