LIMITED LIABILITY COMPANY «DNEPROVSKY SPECIAL TUBES PLANT» Ukraine, 52035, Dnepropetrovsky region, Goryanovskoe village, Goryanovskaya Str., 1 +38 (056) 372-17-27, 372-72-62 e-mail: [email protected], www.dzst.com.ua

Dneprovsky special tubes plant LLC is a producer and supplier of steel seamless cold-rolled tubes (including capillary, thin-walled and extremely thin-walled tubes) of stainless steel, scale-resistant and heat-resistant steel and alloys, Ti and Ti-based alloys, Ni and Ni-based alloys, refractory metals and its alloys (molybdenum, tungsten, tantalum, niobium). Quality of products is provided by the functioning of the Quality Management System certified in accordance with the requirements of DSTU ISO 9001:2009 and by certified multi-testing laboratory (certificate No. 3813-19-VL). At the customer’s request the tubes are inspected by the independent technical inspections.

In 2007, the Plant has mastered the unique production of seamless tubes of refractory metals: molybdenum, niobium, tantalum, tungsten, which are used at 1200˚C-1800˚C. Until now, this production technology remains to be the only one at the CIS territory. The experts of our Plant developed and implemented the special technical requirements: TU U 24.4-33338597-005:2012 named as “Seamless thin- walled tubes of small sizes of molybdenum and niobium alloys”, which are the intellectual property of DSTP.

Such high-technology and critical fields like aerospace engineering, nuclear power engineering, instrumentation technology, mechanical engineering can’t pass without use of tubes of refractory metals. These materials have no alternative as engineering materials in production of parts and assemblies for special-purpose machinery. Using of the high-precision equipment and qualified personnel in this branch, it allows manufacturing the high-quality tubes which have much better properties than tubes which produced in Asia countries. The main range of sizes includes the outside diameter from 0.7 mm up to 48.0 mm and the wall thickness from 0.07 mm up to 2.0 mm. The tubes also can be produced according to the special technical requirements of the customer.

In addition, DSTP produces and supplies seamless cold-rolled tubes of steel grades as (08)12Cr18Ni10Ti, 30CrMnSi, 20A steel as per GOST 19277 named as “Seamless steel tubes for oil and fuel lines” standard. This kind of tubes are used in production of oil and fuel lines of piston, turboprop, turbofan, jet engines as well as of the tube lines for the aircraft construction. The main range of sizes includes the outside diameter from 4.0 mm up to 70.0 mm and the wall thickness from 0.5 mm up to 3.0 mm. The tubes also can be produced according to the special technical requirements of the customer.

There are some more areas where our tubular products are used, such as food industry, chemical industry, oil and gas industry, machine-building, etc. Besides we produce tubes as per GOST 19277 standard, we also produce tubes as per following GOST standards:

- GOST 9940 standard named as “Seamless hot deformed tubes made of corrosion resistant steel” (OD: 57.0-325.0 mm, WT: 3.5-32.0 mm);

- GOST 9941 standard named as “Seamless cold- and warm-deformed tubes of corrosion-resistant steel” (OD: 5.0-273.0 mm, WT: 0.2-22.0 mm); - GOST 14162 standard named as “Steel tubes of small dimensions (capillary)” (OD: 0.3-5.0 mm, WT: 0.1-1.6 mm). The tubes also can be produced according to the special technical requirements of the customer.

More than, Dneprovsky Special Tubes Plant LLC produces seamless cold-rolled tubes of Ti and Ti- based alloys, which are widely used in shipbuilding industry. Ti-based alloys include the following grades: ПТ-1М, ПТ-7М, ОТ4, ОТ4-0, ОТ4-1 which are produced as per technical requirements TU 14-3-820-79, TU 14-3-843-79, GOST 22897. Also, the tubes of Ti-based alloys are used in the aircraft building and aero-engine engineering as the products tube lines and heat-exchange surfaces. The main range of sizes includes the outside diameter from 0.3 mm up to 57.0 mm and the wall thickness from 0.07 mm up to 4.0 mm. The tubes also can be produced according to the special technical requirements of the customer.

The Plant also produces and supplies seamless tubes of heat-resistant alloys with grades CrNi60WTi, CrNi78Ti, CrNi50WMoTiAlNb, which are used in production of details of the combustors of the aero and rocket engines, details of the heating furnaces, tube line systems of the gas-turbine technical equipment, etc.

Dneprovsky Special Tubes Plant LLC has the additional facilities for producing of the other special alloys according to the customer’s specifications.

The specialists of DSTP have mastered the technology of production of seamless cold-deformed elbows (Rmed.≤1OD) of stainless steel as well as Ti and Ti-based alloys. The elbows are produced according to the technical requirements of Ukraine TU U 24.2-33338597-006:2012 named as “Seamless cold-deformed elbows of stainless steel”, which is developed and implemented by our Plant. The elbows are used as the details of the tube communications of the rocket systems and the rocket engines. Dimensions of elbows: from 18.0 x 1.2 mm up to 53.0 x 1.8 mm. The seamless elbows can be produced according to the special technical requirements of the customer. Among the customers of DSTP products are such large industrial companies of Ukraine and Russia as: - Zorya-Mashproekt Scientific-and-Production Complex State Enterprise (Ukraine); - Antonov State Enterprise (Ukraine); - A.M. Makarov Yuzhny Machine-Building Works Production Association (YuMZ) (Ukraine); - Motor-Sich Public Joint Stock Company (Ukraine); - Kharkiv FED State Enterprise (Ukraine); - Alchevsk Metallurgical Integrated Works PJSC (Ukraine); - “OSTCHEM” corporation (Ukraine); - Enterprises of “UkrOboronProm” State Concern (Ukraine); - Gas-turbine engineering research and production center “SALUT” Federal State Unitary Enterprise (Russia); - “PLUTON” Scientific and Production Complex (Russia); - "TORIY” Research and Production Enterprise Federal State Unitary Enterprise (Russia); - “ALMAZ” Scientific and Production Enterprise (Russia); - Scientific Research Institute of Atomic Reactors (Russia); - Hindustan Aeronautics Limited (HAL, India).
