Packing material

Black packaging steel strap (waxed and painted) 32*0,8 mm. Packing interval – 0,5 m from package end and further on at the distance of at least 1,5 m. Packing is carried out by import equipment Signode, providing ideal tension and package safety. Product transportation is possible without using bolsters. While transporting recently produced profiles, one shall take into account that all profiles are thoroughly oiled.

Package length: 6; 11,7 and 12m (other dimensions can be agreed individually).

Integrated Management System

лента оцинкованная, лента стальная оцинкованнаяThe company has developed and implemented an integrated management system (IMS), confirmed by the compliance certificate. The certificate confirms that closed profile of square and rectangular section is produced in accordance with the requirements of GOST ISO 9001-2011 (ISO 9001:2008), GOST R 54934-2012 (OHSAS 18001:2007), GOST (ISO 14001:2004).

Weld seam test

Weld seam test of closed profile is carried out at electric magnaflux plant UMD-101M. Plant operation principle is based on creating of static magnetic field in tested objet and transformation of the field changes (leakage) into electric signal – defect signal. The leakage is generated by geometric and electromagnetic oscillations of the system “converter-product”, i.e. by defects such as steel discontinuity (see pict. 1).

Defect detector works in continuously-automated operating mode and while pipe moves it carries out non-destructive control testing of weld discontinuity, it also registers defects and informs the operator about the quality of weld seam, its deseaming and geometry. Immediate receiving of information shows the welder correctness or incorrectness of pipe forming operation and welding of closed profile.
