With the rapid development of China's economy and the improvement of residents' consumption levels, China's consumption demand for petroleum and petrochemical products has grown rapidly. At present, China is already the world's second largest oil consumer and importer after the United States, and the petroleum and chemical industries have become strategic industries related to national economy and people's livelihood. China's apparent oil consumption has increased from 272 million tons in 2003 to 484 million tons in 2012, with an average annual growth rate of 6.62%, which is higher than the global average annual growth rate of 1.17%. Since China's crude oil reserves are small and unable to meet domestic oil consumption needs, a large amount of crude oil needs to be imported from oil-rich countries. China's crude oil imports increased from 180 million tons in 2003 to 271 million tons in 2012.
 
With the rapid growth of China's petrochemical product consumption and the increase in crude oil imports, China's petroleum and chemical industry has seen a significant increase in fixed asset investment. The investment amount increased from 0.70 trillion yuan in 2007 to 1.76 trillion yuan in 2012. An increase of 20.12%. By the end of 2010, China had built 20 million-ton refineries, 6 million-ton ethylene producers, and 24 million-ton large chemical fertilizer producers. During the Eleventh Five-Year Plan period, China's petroleum and chemical industry's major technical equipment development and innovation levels have been further improved, and some technical equipment has reached the world's advanced level.化技術。 Chemical technology. The rapid development of the petrochemical industry has driven the growth of China's petrochemical stainless steel pipe industry. The growth of domestic refining and chemical equipment and ethylene capacity construction has increased the demand for petrochemical stainless steel pipes. The characteristics of petrochemical facilities and equipment are high safety and reliability requirements, strong technical support, and many varieties and specifications. Special design and manufacturing schemes are required to make the equipment operate under the best design conditions. High-performance stainless steel pipes can meet the needs of the above-mentioned facilities construction and equipment matching, so they are widely used in engineering equipment such as furnace tubes, material transportation, heat exchanger tubes and so on.
 
Driven by factors such as the acceleration of China's urbanization process and the upgrading of residents' consumption, the domestic petroleum and chemical industries will continue to maintain stable growth. According to the "Twelfth Five-Year Development Plan of the Petrochemical and Chemical Industry", energy resources products such as refined oil, natural gas, potash fertilizer, raw materials such as olefins, light hydrocarbons, para-xylene and other domestic raw materials with insufficient production capacity, engineering plastics and other new chemical materials and specialties The demand for chemicals still has considerable room for growth. According to the plan, China will rely on importing crude oil from the sea to improve the refining productivity layout in coastal areas: relying on crude oil pipelines in China, Myanmar, China, Russia, China and Kazakhstan, and along the Yangtze River to improve the refining capacity in Central and Southwest China, and develop Wuhan, Chengdu, Kunming, etc. as the core Central and western inland petrochemical industry concentration area. The concentration of the three major petrochemical industrial areas in the Yangtze River Delta, Pearl River Delta, and Bohai Rim will be further improved, forming 3-4 20 million-ton refinery and three 2 million-ton ethylene production bases. According to the general application case experience of petrochemical industry construction projects, the amount of stainless steel pipes to be applied for a single petrochemical engineering project (500-2000 million tons) is about 400 to 2,000 tons. The investment construction and development of the above key projects, plus existing operations The stainless steel pipes used in oil refining and chemical projects have a certain renewal period, which will generate continuous market demand for petrochemical stainless steel pipes.
