OMK Vyksa Plant Certified by National Welding Control Agency
United Metallurgical Company OMK’s Vyksa plant in the Nizhny Novgorod region of Russia has been certified by the National Agency for Welding Control.
United Metallurgical Company OMK’s Vyksa plant in the Nizhny Novgorod region of Russia has been certified by the National Agency for Welding Control. The company has confirmed that its technology for the production of electric-welded pipes with diameters of 60-530 mm for construction purposes fully complies with the requirements of GOST R 58064-2018. This standard regulates the production of steel welded pipes used in the construction of civil and industrial facilities, operating at temperatures from plus 100 to minus 60 degree Celsius
During the certification, in the presence of an expert from the Head Certification Center of the Upper Volga Region, the plant specialists performed experimental welding of all assortments and tested samples. The quality of welded joints was checked by visual-measuring and ultrasonic methods. Tensile, impact bending, flattening and hardness tests have been successfully tested to determine strength and ductility characteristics. The quality assessment criteria were in accordance with GOST R 58064-2018.
Now the Vyksa plant OMK has the right to produce construction pipes according to this standard with a diameter of 60-178 mm with a wall thickness of 3-12.7 mm, a diameter of 114-245 mm with a wall thickness of 4-11.1 mm and a diameter of 203-530 mm with a wall thickness 4.5-12.7 mm. The obtained certification is to be confirmed every three years.
The Association "National Welding Control Agency" is empowered by the Council for Professional Qualifications in Welding. This is the central body of the Rostechnadzor Welding Production Certification System. NAKS unites organizations involved in conformity assessment in the field of welding. On the basis of NAKS, the Rosstandart Technical Committee TK 364 "Welding and Related Processes" is operating, which is engaged in the development of national standards for welding and their harmonization with international ones.
