The Leningrad Metal Plant i/n Stalin (Leningradskiy Metallicheskiy Zavod imeni Stalina) is located at 19 Palyustrovskaya (now:.Sverd1pvslaya' Naberezhnaya), Kalininskiy Rayon, in Leningrad. The Leningrad Krasnyy Vyborzhets Nonferrous Metal Plant of the Ministry of Nonferrous Metallurgy and, further along the quay,. the Leningrad Machine and Electrical Equipment Plant i/n Sverdlov of the Ministry of Machine Tool Building and Tool Industry are neighboring plants. A branch line from the Finlyandskiy Freight Station on the Oktyabrskaya Rail- road and a wharf on the Neva River serve the plant. The plant is controlled by the USSR Ministry of Heavy Machine Building and is directly subordinate to the Directorate of Boiler and Turbine Building. ~IST.0~7~ 2. The plant was founded as the St. Petersburg Metal Works in 1857 when its principal manufacturing con Ot-e-d of boilers and various metal products for the oil and coal industries. In 1904-1905, the plant first started producing low- rated, steam turbines of 110-1,250 kw; the number turned out up to the time of the Russian Revolution was about 20. Work practically came to a standstill after the Revolution, when some of the shops were shirt down completely. Only individual orders for various metal products were filled. In 1923, the plant became part of the newly created Leningrad-Machine Building Trust and was assigned the task of manufacturing boilers, steam trubines, and water turbines. A considerable part of the plant was evacuated in the fall of 1941 when the German advance threatened Leningrad. Repair of land and naval guns and tanks was carried out in the remaining installations. The period between the time that the siege was raised and the termination of the war was employed in 1e-.1. building the plant and recruiting and training young personnel.

Steam Turbines In 1923, the plant turned out its first steam turbine since the end of the Revolution. These were all low-rated 3,000 kw turbines. In.192 , the Design Office of the plant designed a 10,000 kw steam turbine which was built in 1925. In 1928, the plant turned out 22 steam turbines with an aggregate capacity of 67,000 kw and, in 1929, 30 steam t-urb.iAe..41 with an aggregate capacity of 105,000 kx were turned out.

Special steam turbines praduued by the plant before World War II included marine turbo sets comprising tuxtbine,%condenser, and gearing, These turbines were of various types? e.g.,compound turbines with high-pressure and law-pres- sure chambers of 16,000 kw and. 17,50QLkw ratings and compound turbines with high, medium, and low-pressure chambers of 40,000 kv and 55,000 hp rating. The steam pressure of these turbines varied from 26 to 36 atm abs, the steam temperature being about 385 degrees C. Water Turbines 9. In 1924, the Leningrad Metal Plant began manufacturing water turbines, the first of which wae'a"small-capacity unit'of 55 kw, with a head Of 7.5-m, and a speed of 600 rpm. This turbine was subsequently installecl in the Akhaltaikhe (N 41-38, E 42-59) Hydroelectric Power Station in the Georgian SSR. The second water turbine to be built in 1924 was a horizontaltradial-flow turbine with a rating of 370 kw,,a head of 14 m, and a speed of 214. rpm. The plant produced 14 water turbines it 1928 with an aggregate capacity of 11,000 kw, a figure which was increased to 16,000 kw in 1929 when 19 water turbines were turned out. From 1930, the plant began to specialize in the construction of high-capacity water turbines, the manufacture of small and medium-capacity units being turned over at that time to the Moscow Plant i/n Kalinin (sic) which, however, ceased pro- duction of water turbines some years later. Large-capacity water turbines produced by the Leningrad Metal Plant in the 1930s included a 13,000 kw unit for the Rion (N 42-08, E 41.39) Hydroelectf ie Power Station in the Georgian SSR,built in 1933, and a 7,700 kw unit for the Gizel'-Donskaya (N 43-11, E 44-25) Hydroelectric Power Station in NOrth Osetian ASSR, built in 1934. During the same decade 24,000 kw water turbines were built for hydroelectric power stations at Dzorages decade,-24,-000 Kalagiran (N 40-55, E 44-34] in the Armenian SSR, on the Niva River at Kandalaksha (N 67.09, E.32-26) in Murmansk Oblast, and for the Lower Svir Hydroelectric Power Station. In 1937, the plant produced water turbines with fully automatic control for the Ivankovo in Kalinin Oblast, Skhodnya (N-55-"57p E 37-19) in Moscow 0blast,,and for the Karkmysh4vo (N 57-45, E 28.42) Hydroelectric Power Stations in Pskov Oblast on the Moscow Canal, with capacities of up to 17,000 kw, while,,in 1940 and 1941, large water turbines were made for the Uglich (N 57-32) E 38-20) and Shcherbakov (N 58-03, E 38-50) Hydroelectric Power Stations in Yaroslavl Oblast. The water turbine installed at the Shcherbakov station'is.a_Kaplan turbine of 70,000 kw capacity, with a head. of 12-20 m, speed of 62.5 rpm, rate of flow of 500 cu m of water per second, diameter of'rotor wheel 9 m, weight of wheel 300 t, and total weight of turbine 1,315 t.

PRODUCTION AFTER WORLD WAR II It was not until 1916 that the plant stopped making boilers and started to manu- facture high-capacity steam turbines for power stations and sea-going ship. The Leningrad Metal Plant i/n Stalin shared this assignment with the Kharkov Turbo generator Plant i/n Kirov. The Kharkov Plant manufactures its own: generators., Approved For Release 2008/09/15: CIA-RDP80-0081 OA007700820010-9 Approved For Release 2008/09/15: CIA-RDP80-0081 OA007700820010-9 whereas the Leningrad Metal Plant obtains its generators from the Leningrad Elektrosila Electrical Equipment Plant. The manufacture of low and medium- capacity turbines was entrusted to the Electrical Equipment Plant i-/n Kirov and the Nevskiy Machine Building Plant i/n Lenin in Leningrad, the Ural_Turbine Plant at Sverdlovsk, the Kaluga Turbine Plant, Kaunas Turbine Planttand the Bryansk Krasnyy Profintern Locomotive Plants. That same year the Central Boiler and Turbine Institute (TsKTI), aided by specialists from the Leningrad Metal Plant,issued specifications for types and sites with steam characteristics of 90 atm abs and 480-500 degrees C for large turbines, and 35 atm abs and 435 degrees for medium turbines. The State Standards Co ittee (GOST) approved these in 1947 and made them obligatory for all turbine construction, In design- ing the new high-capacity turbines, the Leningrad Metal Plant and the Kharkov Turbogenerator Plant also standardized 75 percent of the parts used in the manufacture of 25,000 kw and 100,000 kw turbines and continued to produce standard turbine parts of other ratings. Uninterrupted contact is maintained between the Leningrad and the Kharkov plants. In 19514, for instance, engineers of the former plant were employed for some time at the Kharkov plant in assembling and machining parts for 100,000 kw steam turbines, as well as for building water turbines for the Kakhovka (N 146-149, E 33-30) Hydroelectric Power Station in Ftherson:Oblast ''-, Their engineers also worked in 1954 as instructors at the Syzran (N 53-i1, E'48-27) Water Turbine Plant in Kuybyshev Oblast where they advised the local technicians on the machining and assembly of water turbines for the Kama Hydroelectric Power Station in Molotov Oblast. 12.

RESEARCH 33. The Steam Turbine Design Office is under the direction of the well-known scientist Professor Grinbergj who is assisted by a large number of experienced technologists. This office works in close collaboration with various scientific institutes and concerns itself not only with practical problems connected with steam turbine construction, but also with carrying on scientific research. The work of the office has included in the past the development of marine turbines with high steam parameters and at present is engaged on problems connected with the use of gas turbines in ships. 34. The Leningrad Metal Plant has its own hydro-experimental station located on the Skhodnya River in the Khimki Rayon of Moscow Oblast. ',In 1954, engineer Gushchin (fnu) was head of this station,whieh conducts tests on new water tur- bines; rotor wheels and suction pipes. In 1953, the station carried out Approved For Release 2008/09/15: CIA-RDP80-0081 OA007700820010-9 Approved For Release 2008/09/15: CIA-RDP80-00810A007700820010-9 scientific research on auction pipes and rotor wheel chambers with pivoting vanes in collaboration with the All.Union scientific Research Institute of Hydro-Machine-Building (YTCK). As a result of this research work, the design of rotor wheel chambers in all newly-built hydroelectric-;. stations at Kuybyshev, Stalingrad, Kakhovka., Angara, and others Vas modified. In 19514, the experimental station also conducted research on the cavitation properties of water turbines. The first rotor wheel built for the Kuybyshev Hydroelectric Porter Station was subjected to intensive tests at the Skhsdnya Experimental Station before the serial manufacture of these wheels w e begun. 35. There is also a special water turbine laboratory at the plant itself where research on all probl.of water turbine construction is carried out. The work of this laboratory includes the construction of scale models of hydro- electric plants, e.g., a one twentieth scale model of the Kuybyshev station., and models of high-pressure hydroelectric power stations built in the Caucasus. The plant has testing installations and stands for testing hater turbines. Co msent 1. Bryansk also has a turbine plant.
