In recent years, Daqing Petrochemical Company has firmly grasped the favorable opportunity for the national and group companies to develop the refining equipment manufacturing industry, making full use of their own advantages, increasing R&D and production of refining equipment, and forging an important manufacturing base for refining equipment in the Northeast region. , A simple change in the traditional model of outsourcing equipment, has carried out a number of technological innovations, and achieved a successful transformation from equipment users to equipment manufacturers.

The long-term operation of the equipment is the key to the efficient operation of the equipment. The heat exchanger is an important equipment of the oil refining and chemical industry. The performance not only determines the safe and stable production of the equipment, but also plays an important role in energy conservation and emission reduction of the company. In order to provide high-efficiency equipment for production facilities, Daqing Petrochemical Machinery Factory has established a good partnership with ABB Corporation of the United States, mastered the advanced design concepts and the essence of the production process, and formed a unique set of manufacturing technologies and serialized high-efficiency exchanges. Heater products. After the technical breakthrough of this plant, the successfully developed spiral baffle plate type high efficiency heat exchanger was applied to Daqing Petrochemical Company's refinery two sets of atmospheric and vacuum devices and achieved good expected results. At present, more than 50% of the company's heat exchangers are gradually upgraded to high-efficiency heat exchangers, with a heat transfer efficiency of 80% to 85%, and more than a year's worth of recycled heat equivalent to about 30 million tons of standard coal. The nine new heat exchange tubes and spiral baffle plate heat exchangers that have been developed have been widely used in oil refineries such as Zhongyuan, Maoming, Guangzhou, Guangxi, and Dagang, Tianjin, to ensure the high quality, efficiency, and smooth operation of production equipment. .

In order to adapt to changes in the market and further increase the ability to create profitable products, this factory upholds the idea of ​​strengthening the manufacturing industry and the precision-processing sector, and on the basis of consolidating the mechanical processing market in Daqing, it will adopt the form of “selective introduction and joint development” and Many domestic research institutes and universities have established a good cooperative relationship, and have jointly developed and produced high-efficiency cyclone separation equipment, efficient structured packing, three-offset butterfly valves, granulation grating templates, and many Other market prospects with high added value. New products and products are sold in more than 20 provinces, cities, and regions throughout the country, and more than 400 high-efficiency devices have played a role in petrochemical plants and oil field production.

Based on the original products, Daqing Petrochemical Machinery Factory upgraded its R&D focus to localized ethylene equipment and large-scale refinery equipment represented by “San Gao Gao”. After years of research and development, the types of highly efficient energy-saving equipment have changed from the past. The single species has been expanded to 11 species, covering seven sectors of oilfields and refineries, and has obtained 8 national patents. It has now been applied to refineries in Guangzhou, Guangxi, Tianjin, and Daqing, and has seen more Good energy saving effect. At present, Daqing Petrochemical Company has formed an equipment manufacturing capacity with an annual output value of 500 million yuan, ranking among the forefront of China's oil refining and chemical companies.
