DNEPROVSKY SPECIAL TUBES PLANT LLC

The Plant is operating over ten years in the market producing and supplying the seamless up to 140.0 mm in cylindrical products with length from 400.0 up to 4000.0 mm and outside - Dneprovsky F .E. Dzerzhinsky Metallurgical Integrated Works PJSC and other Ukrainian companies, as well as companies from Russian Federation, India, USA, Israel, Kazakhstan, Georgia, Baltic States, etc. Dneprovsky Special Tubes Plant LLC was built in 2003. The plant with its modern technologies produces about 200.000 meters of tubes in a diameter range from 0.23 up to 159.0 mm and wall thickness from 0.07 up to 8.0 mm; seamless elbows (R med ≤ 1 OD) in a diameter range from 18.0 up to 95.0 mm meeting strict requirements of special specifications as per № TU U 24.2-33338597-006:2012; deep drilling of holes with diameter range from 27.0 diameter from 50.0 up to 200.0 mm. - Quality Management System certified according to the State Standard of Ukraine ISO 9001:2009 (certificate No. UA 2.006.07973-13) was adopted at the enterprise. The special acceptance and independent technical inspection the TP No. 23 (Aviatekh - priyomka) is used at the Plant. Certified laboratory for mechanical, metallographic and corrosion tests is operating at the Plant (Certificate No. 3813-19VL). In 2007, the Plant has mastered the technology of tubes production of refractory metals and its alloys (molybdenum, tungsten, tantalum, niobium, etc.). Until now, this technology remains to be a unique one at the CIS countries. About us Alchevsk Metallurgical Integrated Works PJSC; - Kharkiv FED State Enterprise; cold-rolled tubes (including capillary tubes, thin-walled and extremely thin-walled tubes) of Among the DSTP customers are such large industrial companies as: stainless steel, scale-resistant and heat-resistant steel and alloys, Ti and Ti-based alloys, refractory metals and its alloys (molybdenum, tungsten, niobium, tantalum, etc) as well as nonferrous metals. Over this time, DSTP has acquired a reputation of reliable, dynamically developing producer, which makes good use of its scientific and production potential, highly skilled personnel. DSTP activities are based on a customer-oriented approach. The Plant main features are flexible pricing policy, optimum delivery times, high-quality products and up-to-date logistics. -«Zorya»-«Mashproekt» Scientific-and-Production Complex State Enterprise; Armoured Vehicle Plant» State Enterprise; - «ANTONOV» State Enterprise; - «ANTONOV» serial plant, a subsidiary of «ANTONOV» Company; - «Motor-Sich» Public Joint Stock Company; - A.M.

World economy displays upward trend towards increasing the share of high-tech and tantalum, niobium, etc). The plant produces the tubes of refractory metals in a diameter 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, range from 0.7 up to 48.0 mm and wall thickness from 0.07 mm up to 2.0 mm. The tubes are only produced of certified materials. Special-purpose precision 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. Materials to be used in future Tubes of refractory metals equipment, vacuum heat treatment facilities, advanced chemical treatment and finished material and improved accuracy of tantalum and niobium». research intensive works. Today competitive power of a particular enterprise and even machinery intended to operate in aggressive environments and temperatures (1000 °C - 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 of 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 1400 °C). molybdenum alloys» and TU U 24 .4-33338597-007:2015 «Tubes with improved purity of 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 organized 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 4
