The non-destructive ultrasonic testing system for medium-diameter ERW pipes ULTRATUBE has been commissioned at OAO Ural Pipe Plant (Uraltrubprom, Pervouralsk) by specialists of ULTRAKRAFT JSC.
The system is designed to detect laminations, longitudinal and transverse defects and to measure the wall thickness of high-frequency welded (HFW) pipes under production conditions in the longitudinally welded ERW pipe shop.
The automated system is integrated into the ERW pipe production process and allows testing the quality of pipes with a diameter of up to 630 mm and a wall thickness of up to 22 mm.
The pipe metal quality testing is performed in accordance with the requirements of the standards ISO 11960:2001 ("Petroleum and natural gas industries – Steel pipes for use as casing or tubing for wells"), API 5L specification ("Specification for Line Pipe"), API 5CT specification ("Specification for Casing and Tubing"), GOST R 52079-2003 "Welded steel pipes for trunk gas pipelines, oil pipelines and oil product pipelines", GOST R 53366-2009 "Steel pipes for use as casing or tubing for wells in the oil and gas industry", ISO 11960 2004 "Steel pipes for use as casing or tubing for wells", ISO 3183 "Steel pipe for pipeline transportation systems"; DNV-OS-F101 "Submarine pipeline systems".
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.
