Have you introduced the petrochemical industry ??

I. my country's petroleum and petrochemical equipment manufacturing industries have a solid basic oil and petrochemical industry as one of the pillar industries of our country. They occupy an important position in the national economy. In 2001, the production of crude oil was 165 million tons; ; Ethylene production of 4.8067 million tons; 33.965 million tons of chemical fertilizers; 12.038 million tons of synthetic materials, the main economic indicators ranked first in various industries in the country. The development of the petroleum and petrochemical industry has led to the development of oil and petrochemical equipment manufacturing that provides equipment. Since the 50 years of the founding of the People's Republic of China, especially for more than 20 years of reform and opening up, through development, development, cooperative production, and introduction of technology, my country's petroleum and petrochemical equipment manufacturing industries have established a relatively complete complete complete, from small to large, from small to large Manufacturing system. According to statistics, in 2001, 405 enterprises above designated size of petroleum and petrochemical equipment in the industry, with the total industrial output value (current price) of 13.4 billion yuan, a total profit of 290 million yuan, and 128,000 employees. (1) The manufacturing system of oil diamonds and mining equipment has formed the oil diamond and mining equipment manufacturing industry to provide equipment for the exploration and development of land, desert, shallow beach and sea oil, and natural gas. In the early days of the founding of the People's Republic of China, oil was basically dependent on imports, and the manufacturing industry of oil and petrochemical equipment could not be discussed. Only a few small factories in the country produced some petroleum equipment parts. After 50 years of hard work, several more concentrated manufacturing bases have been built: drilling equipment bases mainly based on Baoji, Lanzhou, Nanyang, etc.; oil tool bases mainly in Shanghai and Jiangsu; Drilling Bottom Base; Earth Physics Exploration Equipment Base, which is dominated by Xi'an; a special diesel engine manufacturing base for oil drilling machines mainly in Jinan. The manufacturing of oil collection equipment is scattered throughout the country, and the northeast region is more concentrated. There are not many countries with capacity to produce a set of petroleum rigs around the world, only Britain, Russia, Romania, the United Kingdom, Norway and other countries. my country is the only country in developing countries that can produce a set of petroleum rigs, and has a capacity of about 120 units of the 1000-9000-meter series of rigs an annual production of 1000-9000 meters. At present, the production of a set of oil drilling machine companies has grown to eight. Among them, there are four state -owned enterprises: Baoji Petroleum Machinery Factory, Nanyang Petroleum Machinery Factory, Jianghan Fourth Petroleum Machinery Factory, Shengli Oilfield Power Machinery Factory; two Chinese and foreign joint ventures: Lanshi Kuoming Petroleum Engineering Co., Ltd., Shanghai Sangao Petroleum Equipment Co., Ltd. ; Two private enterprises: Chengdu Yuhong Petrochemical Engineering Co., Ltd., Chuanyou Guanghan Machinery Co., Ltd.. A total of 106 oil rigs were produced in 2001, both the best level in terms of quantity and quality. Oil collection and exhaust well estate device is already a mature product of my country. The maximum pressure of the Oil Oil Pipe Oil Oil Well Device can reach 105MPa, and the maximum pressure of the dual oil pipe oil collection well is 70MPa; the mechanical oil collection equipment has reached the international level;为-7 温, the temperature is 50 ℃ -150 ° C, the pressure is 10MPa and above the various specifications of the set set of electric submarine oil pumps; the hook load is 60-120 tons, the depth of the well repair is 3600-7200 meters, and the shares of Jianghan Petroleum Diamonds are limited. The company is the largest oil drill production company in Asia. Its capabilities are 108 varieties and 230,000 drills an annual output. The domestic oil and gas collection equipment is complete and high-quality, such as 750-3000 meters of 3/h, and 90-550 meters. 10MPa ball valve, 325-1420mm in diameter, wall thickness 6-16mm oil and gas concentration of vowel steel pipes reached millions of tons, as well as manufacturing marine oil and gas concentration transmission single-doting system, floating production oil tanker, shuttle oil tanker underwater pipeline transport system And pressure equipment, etc. (2) The oil chemical equipment manufacturing industry has made a historic breakthrough for 50 years. my country's petroleum refining industry has been developing independently, so it has led to the development of oil refining technology and equipment. At present, 5 million tons/year -old refineries have been manufactured, 8 million tons/year -old decompression distillation device, 2 million tons/year heavy oil catalytic cracking device, 1.5 million tons/year hydrogenation device, 2 million Ton/year -old oil hydrogen desulfurization device, 1 million tons/year delayed coking device, etc. Some highly difficult devices, such as hydrogenation reactors, high -pressure heat exchangers, high -pressure air -cooler for hydrogenation and hydrogen refined devices; centrifugal cyclic hydrogen compressors for hydrogenation and reorganization devices, 50 and 80 tons of piston piston Power -based reciprocating new hydrogen compressor; main fan, oxygen -rich compressor, high -efficiency cyclone separator, external heat machine, hood, and important process pumps for catalytic cracking and delayed coking devices can be manufactured. Once upon a time, the small chemical and medium -sized fertilizers made by my country spread all over the country, solving the urgent need for chemical fertilizers at that time. These chemical equipment, because their technical and economic indicators have lagged behind, are gradually eliminated by large fertilizer equipment.以30万吨/年合成氨、52万吨/年尿素为代表的大型化肥装置的设备，包括关键设备：直径2.8米的快活素合成塔、co2汽提塔、原料气压缩机、氨压缩机、 The synthetic gas compressor and CO2 compressor have been successfully developed. Therefore, my country's petroleum and petrochemical equipment industries are dominated by domestic markets, to going abroad and integrating into the international market. The conditions for entering the new stage of development have matured, and they will definitely be promising.
