The overall level of the industry needs to be improved
Valves are indispensable fluid control equipment for various departments of the national economy such as petroleum, chemical industry, power stations, long-distance pipelines, shipbuilding, nuclear industry, various cryogenics, aerospace, and marine oil extraction. After more than 20 years of development, there are about 6,000 valve companies of various sizes in China, and the number of companies ranks first in the world, of which 900 have an annual output value of more than 5 million yuan.
From the product point of view, China's valve industry has now been able to produce more than 10 categories of products, such as gate valves, globe valves, ball valves, butterfly valves, safety valves, check valves, throttle valves, plug valves, pressure reducing valves, diaphragm valves, Traps, emergency shut-off valves, etc., the maximum operating temperature of 570 °C, the lowest is -196 °C, the maximum pressure of 600MPa, the maximum diameter of 5350 mm.
In addition, according to relevant department statistics, China's valve market turnover is as high as 50 billion yuan each year, of which more than 100 billion yuan of the market has been occupied by foreign valve companies. Although China's valve industry has achieved great development through reform and opening up, there are still some problems: Due to the low level of repeated construction, the leading products of valve companies are still dominated by low-end mass products.
In addition, at present, various valves produced by Chinese companies have the drawbacks of external leakage, internal leakage, poor appearance quality, short life, inflexible operation, and unreliable valve electric devices and pneumatic devices. Some products are only equivalent to The international level in the early 1980s. Some valves required on high temperature and high pressure and critical equipment are still dependent on imports. In addition, China's valve industry in the industrial structure, the valve industry's industrial chain, as well as the industry's degree of specialization, compared with foreign countries, there is a big gap.
Industry experts analyzed that the main reasons for the low quality of domestic valve products are: After the rapid expansion of the market, the existing state-owned valve companies have been shut down and transferred, and private enterprises have developed rapidly. The private enterprises have a low starting point, technical strength is very weak, equipment is simple, and most of the products are imitating production, especially low-pressure valves for water supply and drainage. The problems are even more serious.
Drive technological development with technological innovation
How to break this bottleneck and accelerate the development of the valve industry? Song Yinli, general secretary of the valve branch of the China General Machinery Industry Association, believes that in the light of the changes in the valve market and the development of national projects and related policies in the future, the technology and product development of valve companies in the future should focus on the following aspects:
In terms of product development, it is necessary to focus on large-scale projects. First, develop complete sets of engineering valves, and second, pay attention to the product's multi-species and multi-standard production. According to the current national key project development plan, the demand of the valve industry during the “Eleventh Five-Year Plan†period and the following years are mainly in the fields of long-line pipeline valves, “South-to-North Water Diversion Project†and other fields. Only long-line pipeline valves, "Eleventh Five-Year Plan" and the next few years are expected to build 20,000 kilometers of gas pipelines, and there is a great demand for large-scale pipeline ball valves. During the “Eleventh Five-Year Plan†period, it is estimated that a new high-pressure crude oil pipeline will be 5,000 kilometers, requiring more than 3,000 large-diameter high-pressure valves. The “South-to-North Water Transfer Project†is a cross-century project in China. The total investment for the East, Central and West Third Lines needs to exceed RMB 450 billion. Among them, the Eastern Water Transfer Project requires a large number of large-diameter gate valves, special square gate valves, special butterfly valves, and pumping station supporting valves.
In terms of technological innovation, it is important to emphasize the adjustment of product structure and research and development of products with high added value and international leading level. West-East Gas Pipeline tendering, the domestic valve companies have lost all is a painful lesson. With painstaking experience, in order to rejuvenate the valve industry, we must research and develop valve products with high technological content, high added value, and internationally advanced standards.
The implementation of technological innovation, research and development of new products, companies have several ways to go: First, and institutions of scientific research institutions, such as the recent Kaifeng High Pressure Valve Factory and the Chinese Academy of Sciences under the "3D" company co-developed power station boiler steam regulator is With international leading products, its “pressure drop†is much lower than international standards, and it has very broad prospects in the power station industry. Second, it cooperates with foreign countries or adopts the form of technology introduction. Zigong High Pressure Valve Co., Ltd. and Simbelon of Italy The cooperation has shortened the gap between our ball valve products and foreign countries. Of course, qualified companies can also independently research and develop.
In terms of market development, we should implement a diversified sales strategy and strive to open up the international market. To open up the international market, we must first pay attention to the cultivation of foreign trade talents; Second, we must learn to use the Internet and information technology to capture business opportunities; Third, we can cooperate with some domestic foreign trade companies to expand exports through its channels; The fourth is that qualified companies can use external peripherals. Sell ​​or start a factory.
Industry experts believe that the most effective way to quickly change the status quo of low-level redundant construction among industries is to achieve capital expansion through joint, merger, and reorganization between enterprises, so as to further expand market share so that they can stand in the competition. Unbeaten. This is a relatively popular practice in the current international economic field and is also a directional issue in the development of the valve industry in the future. As long as there is a possibility of alliance between enterprises, they can boldly try to break the regional boundaries, break the ownership boundary, break the traditional boundary of professional division of labor, and strive to create a number of enterprise groups with output value exceeding 500 million yuan and 1 billion yuan in the short term.
“In the fierce market competition, whoever has good technology, who has excellent product quality, and who can continuously develop new products, whoever wins the competition in the competition,†said Ye Jixuan, president of Zhejiang Yongjia Pump Valve Association. Held on the 21st at the fifth general meeting of the China General Machinery Industry Association valve branch in Hangzhou.
