Stainless Tube Plant Dnepr-GL was built at the end of 2003. And already at the beginning of the year 2004 it started production of tubular products. At present an annual output of the enterprise is over 140 000 running meters of various tube types from 0,15х0,05 mm to 35х6 mm.
Capillary, light-wall and ultra light-wall tubes of stainless metals, heat-resistant steel and titanium-based alloys make up 80% of production volume.
In 2007 the enterprise fully developed the manufacture of refractory metal tubular products (molybdenum, tungsten, tantalum, chromium, niobium, etc.). A complete production cycle is supported by implementation of technological innovations and installation of new equipment. At the present time this production is unique in CIS territory.
