From 22 to 30 April, specialists of ULTRAKRAFT JSC successfully commissioned new equipment at Plate Mill Shop No. 3 (LPTs-3) of the Cherepovets Steel Mill (CherMK) of OAO Severstal: the ultrasonic plate testing system ULTRAPLATE.
The non-destructive quality testing equipment is based on EMAT technology and can detect not only internal defects in plates, which is standard for similar systems, but also surface defects, which is a truly cutting-edge technology in heavy plate production. It should be noted that the equipment can test plate at temperatures of up to 720 °C.
The OAO Severstal corporate newspaper published an article on the modernisation of outdated equipment and the commissioning of a modern non-destructive plate testing system - the ULTRAPLATE automated ultrasonic testing system.
Why ULTRAKRAFT
In-house development
We design and manufacture systems for ultrasonic testing, geometry measurement and degaussing of rolled metal.
Certified quality
Our quality management system is certified to ISO 9001:2015.
International requirements
Our equipment meets GOST and API 5L, and the requirements of Shell, ExxonMobil, Gazprom, Transneft and DNV.
Industry recognition
“Exporter of the Year”, winner of the “100 Best Goods of Russia” award.
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.
