1、 Global valve Market
Due to the increasingly fierce competition in the global valve market, many world-famous valve manufacturers have closed their plants in North America, Europe and Japan and moved to China, India, South Korea and central Europe to reduce valve manufacturing costs and increase sales profits. With the development and utilization of oil and natural gas in China, the valve market in China has increased greatly, which makes most valve manufacturers pay more attention to building factories in China. As a result, many enterprises have built factories in China to shorten the delivery time.
In 2004, the American Valve Association announced that the domestic valve market share in the United States reached 3.18 billion US dollars; according to the data of China General Machinery Association, the valve market in China exceeded 20 billion yuan, and by 2010, China's domestic valve demand will reach 34.5 billion yuan. The sales volume of various valves in the global market is about 40 billion US dollars. There are more than 2000 valve manufacturers in China, together with more than 1400 valve manufacturers in other developed and developing countries, accounting for 80% of the global market share; more than 10 valve allied companies have a global market share of 20%.
There are many kinds of valves and they are widely used. Oil and natural gas industry has always been a big buyer in valve market. Figure 1 shows the usage of valves in various fields. From Figure 2, we can see that oil (including oil refining) and natural gas are widely used, accounting for 37.4% of the total consumption; valves in the energy sector account for 21.3%; the chemical industry ranks third, accounting for 11.5%; followed by water treatment and sewage treatment, 11.4%.
2、 Development of main valve Market
1. Oil and gas industry
In North America and some developed countries, there are a lot of planned and expanded oil projects. In addition, because people pay more and more attention to environmental protection and the state has established environmental protection laws and regulations, the refineries established many years ago must be rebuilt. Therefore, in the next few years, the investment in oil development and refining will continue to grow. The construction of China's oil and gas long-distance pipeline and the construction of Russia's long-distance pipeline in the future will directly promote the growth of valve market in the oil industry. As shown in Figure 2, according to the long-term development of oil and gas development and transportation valve market, it is predicted that the demand for valves in oil and gas development and transportation will increase from 8.2 billion US dollars in 2002 to 14 billion US dollars in 2005.
2. Energy industry
For a long time, the demand of energy industry for valves has been maintaining a solid and stable growth rate. The total power generation capacity of thermal and nuclear power plants built in the world is 2 679 030 MW, that of the United States is 743 391 MW, and that of new power plant projects in other countries of the world is 780000 MW, which will increase by 40% in the next few years. The energy market in Europe, South America, Asia, especially China will become the new growth point of valve market. From 2002 to 2005, the energy market demand for valve products will increase from 5.2 billion US dollars to 6.9 billion US dollars, with an average annual growth of 9.3%, as shown in Figure 3. 3. Chemical industry
The chemical industry ranks at the forefront of the industry with an output value of more than 1.5 trillion US dollars, which is also one of the big demand markets for valves. Chemical industry needs industrial valves with mature design, high processing quality and rare materials. In recent years, the chemical market competition has become extremely fierce, many chemical manufacturers have to cut costs. However, in 2003-2004, the output value and profit of the chemical industry doubled, and the demand for valve products ushered in a new peak in the past 30 years. As shown in Figure 4, after 2005, the demand for valve products in the chemical industry will grow at an annual growth rate of 5%.
3、 Influence of oil and gas industry on valve technology
Although the range of valve products involved in the development and transportation of oil and natural gas has basically not changed in the past century, valve manufacturers have been constantly updating valve technology to actively respond to the changes in the oil and gas industry market. If we want to keep ahead in the market or not to be left behind, valve manufacturers should constantly update the technology and process of valve design, manufacturing, service and sales. The fact is that oil companies have more and more requirements on valve manufacturers: on the basis of providing reasonable prices, advanced valve manufacturers must be good at solving the problems faced by oil companies. In the case of worse working environment and stricter environmental protection requirements, they should extend the performance of valve products and provide more service capabilities.
(1) The demand for oil and natural gas in the metal seal world market is growing rapidly, and the footprint of developing crude oil has also stepped into every corner of the earth. The extraction of crude oil puts forward new requirements for equipment. For example, ultra deep well technology poses challenges of ultra-low temperature and ultra-high pressure to equipment. The extraction of ultra heavy crude is a profitable option, especially when crude oil reaches $30 a barrel. At present, high concentration of asphaltene and other impurities make it difficult to transport and process crude oil. Generally, the soft sealing ball valve used in oil pipeline can not meet the requirements of working conditions, which requires valve manufacturers to develop metal sealed ball valves and adapt to the changes of temperature and pressure, and even ensure absolute sealing when conveying solid medium (hydroxide, coke, etc.). The metal sealing technology benefits from the development of surface spraying technology. Valve manufacturers hope to use this technology to maintain a leading position in the market, and put spraying technology into the development strategy. They cooperate with research institutes and universities to develop the next generation of "superhard" coatings.
