Purpose of the development: Designed for automated ultrasonic testing of longitudinal welds pipe diameter 508 - 1420 with a wall thickness of 7-50mm.

Recommended application field: Land longitudinal welding of large diameter pipes.

Technical characteristic: Values of the basic parameters of the installation : - Operating frequency of 2.5 MHz , 4.0, 5.0 ; - Controlling the speed in m / min , max . 30 ; - Speed range , at least 0.3 - 30; - Number of ultrasonic channels 20 pcs ; - The frequency of the probe pulses Hz, providing parcel 2 pulses per 1 mm 1000 ; - Sensitivity reserve channels in dynamic mode , not worse, 12 dB ; - Uncontrolled zone at the ends pipes , mm 30 ; - Precision laser tracking reinforcing bead weld horizontal plane , mm, within ± 1,5; - Adjustment of the acoustic gap , mm, in the range of 0 - 5; - Water flow , l / min , no more than 50 ; - Power consumption , kW, not more than 8 .

Advantages over analogues: The distinguishing feature is the realization of angles from 40 ° to 70 ° without changing the ultrasonic transducers.

The development stage readiness: Introduced in production

Description of the development:
()
The unit is designed for automated ultrasonic testing of welds on pipes with diameter of 508 - 420 with a wall thickness 7 - 50 mm in the mass production of pipes in order to detect defects such as cracks, pores , slag, lack of fusion . The unit provides : - For sonic weld throughout the thickness of the tube wall on both sides of the weld , revealing the different orientations ( longitudinal, transverse , etc.) defects; - Automatic quality control of the acoustic contact for flaw detection channels. A characteristic feature is the implementation of ultrasonic testing on transverse defects acoustic head , standing directly on the weld with ultrasonic transducers operating in the immersion version. Applied direct ultrasonic transducers are inclined at an angle of 18 ° to the axis . The angle of entry into the metal - 45 °. Distance radiating surface probe to roll weld reinforcement - 65 mm. Abdominal defects such as lack of fusion , weld , cracks reflect ultrasonic waves predominantly in the mirror direction , so when you enter inclined , these ultrasonic waves to detect defects at the best control in a " tandem" . The design of acoustic unit implements the scheme "tandem" ultrasonic testing as a locally - immersion option.
