The modernisation was carried out in several stages under live production conditions without interrupting the process flow. The final ultrasonic inspection complex consists of two ULTRAPIPE automated systems ("ULTRA-PE-1420.004") designed for testing the weld, the heat-affected zone and the pipe ends. Both systems of the complex can perform ultrasonic testing using either conventional piezoelectric probes or piezoelectric phased arrays.
In addition to conventional ultrasonic testing methods, the systems implement TOFD and ON-BEAD techniques, which reliably detect weld discontinuities in accordance with the requirements of international and national standards, as well as the specifications of OAO Gazprom and AO Transneft.
The ultrasonic inspection complex has already been successfully certified by DNV inspection to the requirements of the "South Stream" and "Nord Stream" projects.
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.
