Editor's note: The valve is a control component in a fluid delivery system and has a wide range of applications in many areas, such as water conservancy and hydropower, petroleum and petrochemical, energy industry, urban engineering, nuclear power industry and so on. However, each industry has different requirements and requirements for valves in terms of working conditions, media, seals, etc., which also results in further market segmentation of valve equipment for different industries. In this case, each valve Manufacturers should choose a professional development path to seize the valve market.
As a general-purpose pipe, the valve has such functions as cut-off, regulation, diversion, anti-backflow, voltage regulation, diversion, or pressure relief. Valves used in fluid control systems, ranging from the simplest shut-off valves to various valves used in highly sophisticated automatic control systems, are quite diverse in variety and size. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurries, oils, liquid metals, and radioactive media.
Valves are widely used in many fields, including water conservancy and hydropower, urban pipe networks, petroleum and petrochemical, sewage treatment and many other industries. Due to different conditions in different industries, different projects in terms of working conditions, media, seals, etc., technical requirements for valve equipment types, materials, pressure levels, etc. are not the same, thus resulting in further valve equipment for different industries. Market segmentation. Under such circumstances, the valve manufacturers have chosen a professional development path. They are not satisfied with the production of only a single valve device. Instead, they are committed to providing overall projects through the expansion of product lines or seeking cooperation. solution.
Gate valves and other low-tech products compete fiercestly in infrastructure construction is the focus of China's economic construction, water supply and drainage projects, especially large-scale sewage treatment projects, including the pipelines, valves, including water treatment equipment manufacturing industry has formed a strong water industry. Provide a good opportunity for the development of the valve industry. Valves are mainly low-pressure valves in the water treatment industry, such as butterfly valves, gate valves, and check valves. In the water supply and drainage project, medium and low pressure valves are widely used, especially low-pressure and large-diameter valves (low pressure valves are valves with a nominal pressure of PN ≤ 1.6MPa), and medium pressure valves (PN2.5-6.4MPa) are less. Gate valves and butterfly valves are the most basic and widely used leading products.
It is understood that there are more than 2,000 valve companies with a certain scale on the market, most of which are located in Jiangsu, Zhejiang and Central Plains. Due to the relatively low technical content of products, the competition is even fiercer.
Nuclear power valve equipment manufacturers supply more and more specific trends The nuclear power industry market is huge. The National Development and Reform Commission has repeatedly stated that by 2020, nuclear power installed capacity can reach 60 million KW, which is higher than the original estimated 40 million KW. Based on this estimation, by 2020, the total investment in China's nuclear power construction will reach about 750 billion yuan, of which investment in equipment will be about 340 billion yuan, if the localization rate of equipment nuclear islands reaches 70%, the localization rate of conventional islands will be 80%, and auxiliary equipment will be domestically produced. If the conversion rate is 90%, domestic equipment companies will face at least over 250 billion yuan of market. According to calculations, the market demand for a nuclear power plant with 2 sets of million kW nuclear power units requires 30,000 kinds of valves, including 13,000 sets of valves for nuclear islands (NI) and 13,000 sets of valves for conventional islands (CI). There are 0.35 million valves (BOP) for the facilities (Table 2, Table 3, and Table 4). According to the annual calculation of 2.5 million kW nuclear power units, the annual demand for nuclear power valves is 37,500 units.
In recent years, the construction of China's power stations has grown to large scale, so large-diameter and high-pressure safety valves and pressure reducing valves are required, and valves must be opened and closed quickly. The needs of complete sets of projects, valve supply from a single species to more varieties and more specifications. The need for a valve for an engineering project is increasingly provided by a valve manufacturer.
The demand for natural gas for the development and transportation of natural gas will continue to grow With the shift of petroleum development to oil fields in the interior and offshore oil fields, and the development of thermal power from 300,000 kilowatts to over 300,000 kilowatts of thermal power and hydropower and nuclear power in the power industry, valve products The performance and parameters of the equipment should also be changed accordingly. In North America and some developed countries, there are many oil projects to be built or expanded. In addition, as people pay more and more attention to environmental protection, the country has established environmental protection laws and regulations. Therefore, the refineries established many years ago must be rebuilt, so in the future several During the year, the funds invested in oil development and refining will maintain its growth momentum. The construction of long-distance oil and gas pipelines in China and the construction of long-distance pipelines in Russia in the future will directly promote the growth of the oil industry's valve market.
According to the long-term development of the oil, natural gas development and transmission valve markets, the demand for valves for oil and natural gas development and transportation will continue to grow.
The chemical and energy industries have become a new growth point in the valve market. The other side of energy development is energy conservation. Therefore, from the aspect of energy conservation, steam traps should be developed and developed to subcritical and supercritical high parameters. For a long time, the energy industry's demand for valves has maintained a solid and stable growth rate. The total power generation of thermal power stations and nuclear power stations built around the world is 2,679,030 MW, and that of the United States is 743,391 MW. The power generation of new power station projects in other countries is 780,000 MW, and will increase by 40% in the next few years. The energy market in Europe, South America, Asia, and especially China will become the new growth point for the valve market.
The chemical industry ranks first in the industry with an output value of more than 1.5 trillion US dollars and is one of the largest demand markets for valves. The chemical industry needs many industrial valves with mature designs, high processing quality, and rare materials. In recent years, competition in the chemical market has become extremely fierce. Many chemical manufacturers have to cut costs and face competition.
