World economy displays upward trend towards increasing the share of high-tech and research intensive works. Today competitive power of a particular enterprise and even economic sector on the whole has direct relation to the use of brand new raw materials in production known as «coming materials». This group is generally deemed to include tubes of refractory metals (TRM) production such as molybdenum, niobium, tungsten, tantalum, etc. Aerospace engineering, aircraft, nuclear power engineering, instrumentation technology, mechanical engineering, electronic and electrical engineering, medicine...none

• f these industries today can do without use of tubes of refractory metals. They have no

alternative as engineering materials in production of parts and assemblies for special-purpose machinery intended to operate in aggressive environments and temperatures (1000 °C - 1400 °C). Dneprovsky Special Tubes Plant Ltd (DSTP) is the only one in Ukraine and CIS countries specializing in production and supplying of tubes of refractory metals. Jointly with leading scientists in this branch and basing on in-house production facilities, the company has

• rganized high-tech and research-intensive production of tubes of refractory metals. The

Plant has all required specifications and technological documentation for all product types. Our Plant has developed the new Technical Requirements for tubes of refractory metals - TU U 24.4-33338597-005:2012 «Seamless small-size and thin-walled tubes of niobium and molybdenum alloys» and TU U 24 .4-33338597-007:2015 «Tubes with improved purity of material and improved accuracy of tantalum and niobium». The tubes are only produced of certified materials. Special-purpose precision equipment, vacuum heat treatment facilities, advanced chemical treatment and finished goods finishing technologies are used in producing the products. Certified Quality Management System was adopted at the Plant. DSTP owns full technological complex, which is necessary for producing TRM. The Company produces commodity quality goods requiring no additional treatment. High accuracy technologies enable DSTP to produce thin-walled and extremely thin- walled tubes and capillary tubes of refractory metals and its alloys (molybdenum, tungsten, tantalum, niobium, etc). The plant produces the tubes of refractory metals in a diameter range from 0.7 up to 48.0 mm and wall thickness from 0.07 mm up to 2.0 mm. Market research carried out by the specialists of DSTP revealed that refractory goods market is nowadays fast-moving. Rapid development of robot technique and instrumentation, electronics, motor vehicle manufacturing, chemical and petrochemical industries, aerospace industries, application of new technologies evoke the demand for tubular goods of this segment.
