In recent years, under the background of economic globalization and fierce competition, the world industrial steam turbine manufacturing industry has experienced continuous mergers and acquisitions. In 2000, the Japanese EBARA company bought all the shares of America ELLIOTT company, set up a ELLIOTT-EBARA turbo machinery company. In 2001, Germany MAN group, recombinant GHHBOSIG and Suhl life, forming MANTURBO company. SIEMENS acquisition of DEMAG DELEVAL company and reorganization of SIEMENS turbine machinery.
Steam turbine manufacturing enterprises in China had also been merging and acquiring. Through the introduction of digestion technology and innovation, has been formed manufacturing industry of the industrial steam turbine with the foreign advanced technology.
SIEMENS, MANTURBO, HANGZHOU STEAM TURBINE (HTC), DRESSER-RAND, MITSUBISHI and ELLIOTT lead the world's large industrial steam turbine group.
SIEMENS
Siemens company acquired DEMAG DELAVAL Turbine Company in 2001 then formed SIEMENS turbine machinery department, places a total of 2650 employees.
Siemens company has 150 years of history, has a variety of turbomachinery patented technology that can produce various types of centrifugal compressor and turbine, as the ancestor of global industrial steam turbine.
In the middle of 1970, 8 of 13 units used in 300,000 ton/year output of chemical fertilizer factory were produced by SIEMENS.
While in 1980, Siemens had exported advanced technology to China. Through this output, China were able to increase the level of Industrial Steam Turbine technology which is then bring China as one of global leader in this industry. After 1990, along with huge development of global chemical industries, SIEMENS industrial turbine is widely used in various fields.
MANTURBO
In 2001, the German MAN group merged GHH BOSIG and Switzerland GHH Sulzer, then established MAN TURBO company. MANTURBO is one of the world's top 500 enterprises, one of ManAG Group subsidiary. ManAG is the world's largest compressor equipment manufacturer, with annual sales of 13.000.000.000 euros.
HANGZHOU STEAM TURBINE (HTC)
Hangzhou Steam turbine is China's largest and most powerful technology of industrial steam turbine manufacturer, formerly known as the Hangzhou Steam Turbine Factory. In the 1980, Siemens Factory from Germany introduced a complete set of reaction type of industrial steam turbine manufacturing technology to HTC. Through absorption, transformation and innovation, HTC successfully produced about 4000 sets of industrial steam turbine and sold back to Europe and other developed countries. Hangzhou Steam products are widely used in the fields of petroleum, chemical, metallurgy, national production, electric power, military etc. With the constant expansion of the chemical plants in China, HTC has become the world's greatest annual production of steam turbine. HTC produces industrial steam turbine by using reaction type of building block technologies,compact structure, precision machining, wide application range. Since 21st century, HTC through Siemens upgrading technology and its own innovation research and development, forming more than 600 type of industrial steam turbine product. Hangzhou steam production of 100,000 ASU in Huaning coal project has become the world's largest power output, single industry-driven turbine on top level product, it also indicates that China has become one of the world's leading industrial steam turbines.
DRESSER-RAND
United States Dresser-Rand is one of the largest compressor manufacturing company in the world. Subsidiaries and associated companies around the world with ten manufacturing plants and laboratories, and more than more than 70 business office, over more than 30 service centers and nearly 8,000 employees and professionals engaged of 92% of bachelor in engineering degree . Total 1993 revenues of 1.2 billion dollars, mainly from the oil and chemical industry. The company is committed to the development of new technologies, new processes, new materials, new products, commitment to quality and service. Turbomachinery Department of the company's headquarters is based in Orion, New York. The company's main products include centrifugal compressors, axial-flow compressors and impulse turbine.
MITSUBISHI
Mitsubishi heavy industries, Japan's largest military-industrial machinery group. Established in 1871, there are 43,400 people,there are 14 factories, 6 institutes, engaged in the production of General machinery, Cosmos machinery, aviation, such as air conditioning, with annual sales of up to 2.5 trillion yen. Mitsubishi Heavy industries started in 1917 with its own technology in the production of steam turbine for power generation, steam turbines for the plant is mainly production, high sand production in Hiroshima and Nagasaki produced by the three factories.Currently, Mitsubishi the production of compressors and turbines for ethylene, fertilizer and petrochemical industries as well as oil refining, gas separation, gas transportation, separation, blast furnaces and other fields.
ELLIOTT
ELLIOTT company headquartered in the United State of Pennsylvania , founded in 1895, ELLIOTT centrifugal compressor and turbine products are widely used in air separation, steel, petrochemical, textile, pharmaceutical, power generation, automotive, glass, electronics, paper and other industries. . In 2000, the company was acquired by ELLIOTT EBARA company in Japan, set up a ELLIOTT-EBARA turbomachinery company, headquartered in tokyo.
