On 28–31 May 2013, the town of Zelenogorsk near St. Petersburg hosted the XXI St. Petersburg Conference "Ultrasonic Flaw Detection of Metal Structures" under the motto "From Theory to Practice and Higher Efficiency of Ultrasonic Testing". More than 150 specialists from Russia, Belarus, Moldova, Ukraine, Bulgaria, Germany and other countries took part in the conference.
ULTRAKRAFT JSC presented its latest achievements in automated testing of plate for the detection of internal and surface defects by non-contact methods.
An automated ultrasonic testing system for pipes with diameters of 426–1420 mm has been shipped to the customer. The system is designed for full-coverage (100 %) ultrasonic quality testing of the welded joint, the base metal of the weld-adjacent zone and the pipe ends.
Testing tasks
detection of longitudinally and transversely oriented defects: lack of penetration, cracks, pores, slag inclusions;
detection of laminations in the base metal of the weld-adjacent zone;
detection of laminations in the base metal of the pipe ends;
wall thickness measurement.
Areas tested
weld seam;
weld-adjacent zone;
pipe end sections.
The equipment can test both single-seam and double-seam pipes.
The configuration, systems, number and parameters of the ultrasonic transducers used, the scanning parameters, sensitivity and testing criteria have been selected to fully meet the requirements of the PAO Transneft standards (OTT-23.040.00-KTN-135), API 5L, GOST 31447, GOST 14782, ISO 3183, GOST R 54382 and STO Gazprom 2-4.1-713-2013.

On 18 January 2026, the management system certification body "Test-St. Petersburg" decided to recertify ULTRAKRAFT JSC. The company's quality management system has confirmed its compliance with the requirements of the international standard ISO 9001:2015 and the national standard GOST R ISO 9001-2015.
Certificates No. RU.QM075.00114 (ISO 9001:2015) and No. ROSS RU.13SK03.00288 (GOST R ISO 9001-2015) have been issued. Both are valid until 17 January 2029.
Scope of certification: development, design, manufacture, supply, warranty and after-sales service (including the supply of components) of automated systems, instruments and complexes for measuring geometric parameters and for non-destructive testing of products, billets and semi-finished products made of various materials, as well as automation of process lines in metallurgical production.
The quality management system of ULTRAKRAFT JSC has been certified since 2011.
