Quality Control

The Company operates and is continuously upgrading its corporate quality management system, and TMK’s plants make use of local systems of environmental management and occupational health and safety that are certified and audited annually by recognized international certification bodies.

All TMK tubular products conform with national and international standards.

In 2011, TMK implemented the following projects in the area of quality management:

Upgrading of the corporate quality management system:

  • Executive managers at TMK plants received corporate training in Lean Six Sigma by SSA & Company
  • 21 pilot improvement projects aimed at improving project quality, process efficiency and reducing cycle times were implemented through the use of Lean Six Sigma methodologies, as well as economizing expenditures, including:
    • improved manufacturing process of hot-rolled pipes (Sinarsky Pipe Plant);
    • improved continuous casting production technology for billets of size 400mm and pipes of steel grade 20KT (Seversky Tube Works);
    • improved the process of oil and gas pipe heat treatment under TU 14-3R-91-2004 in order to reduce production costs (TAGMET);
    • increased service life of PQF continuous mandrel mill (TAGMET);
    • provided required geometrical parameters of pipes with premium connections (Volzhsky Pipe Plant).

The expected economic effect from implementation of projects is RUB 400 million.


  • A recertification audit for compliance of TMK’s corporate quality management system with the requirements of ISO 9001 extended for 3 years the certificate issued by the international certification body Lloyd’s Register.
  • Products manufactured by the Volzhsky Pipe Plant, TAGMET and Sinarsky Pipe Plant were certified for compliance with European standards and directives, including PED 97/23/EG AD-2000-W0; they also obtained the right to bear the CE mark for products manufactured for pressure vessels.
  • Seversky Tube Works, TMK-CPV and Volzhsky Pipe Plant were issued certificates of conformity of quality management systems to the STO Gazprom 9001-2006 standard.
  • The nondestructive testing laboratory at the Sinarsky Pipe Plant was certified for compliance with the nondestructive testing requirements of Russia’s State Committee for Industrial and Mining Safety Supervision.
  • TMK Oilfield Services undertook activities to confirm product conformity to national standards, technical regulations; the corresponding certificates were received
  • TMK-RESITA certified products (continuously cast billets and blooms from carbon, carbon manganese and alloy steel) at DET NORSKE VERITAS.


TMK-Kaztrubprom was qualified at Gazprom, TNK-BP, Karachaganak Petroleum Operating BV, and Tengizchevroil. It was also included in the Register of Domestic Producers of the Republic of Kazakhstan after obtaining a certificate of origin (CT-KZ). As a result, the company has established itself as a reliable supplier of tubular products and has been able to increase the participation in tenders for the supply of products in Kazakhstan.

Intercompany cooperation

  • Volzhsky Pipe Plant, Sinarsky Pipe Plant and Kaztrubprom carried out work to grant Kaztrubprom the right to apply API alternative markings;
  • TMK-ARTROM mastered production of casing from a new grade of steel (St 1340) developed by TMK-RESITA, as well as heavy-walled drill pipe.
