1. Characteristics of valve market at home and abroad

From the perspective of the entire valve market, there are mainly two:

1. In the domestic market, the domestic market is divided into the project market for new construction and expansion projects, and the market for maintenance and renovation projects of old installations.

From the perspective of these two markets, the supply of ordinary valve products is severely surpassing demand. Secondly, companies are overwhelming, disorderly competition, counterfeit and inferior... The market is very irregular, leading to fierce competition among certain valve manufacturers. During the year, the company suffered substantial losses in successive years. From the perspective of the needs of these two markets, with the development and improvement of the market economy, especially the Progressive World Trade Organization (WTO), the market changes more and more, enterprises are more and more affected by the market, and users have more and more influence on the market. The demand for products is getting higher and higher, and the demand for product development and production cycle is getting shorter and shorter.

2. Foreign markets. The foreign market has been very active in recent years and the competition is fierce. The import and export of valves in East Asia and Southeast Asia has grown rapidly, the market trade between developed countries such as the European Community in North America has continued to develop, the exports of Germany, Italy, Japan, China and other countries and regions have expanded, and the imports of the United States, the United Kingdom, France and other countries have increased rapidly. Growth has formed the support point for the prosperity of the international valve market. Moreover, due to the further internationalization of the world economy, multinational companies will continue to promote the development of the international valve market. The regionalization of international trade has become another major feature.

2. Domestic market

There are about 2,300 valves produced by three companies in my country, and the valve products they can provide are in several categories, with more than 3,500 varieties and more than 40,000 specifications.

(1) Valves for urban construction: Low-pressure valves are generally used in urban construction systems, and they are currently developing towards environmental protection and energy saving. Environmentally friendly rubber plate valves, balance valves, centerline butterfly valves, and metal seal butterfly valves are gradually replacing low-pressure iron gate valves. Most of the valves used in domestic urban construction are balance valves, soft-seal gate valves, butterfly valves, etc.

(2) Valves for urban heating: In the urban heating system, a large number of metal-sealed butterfly valves, horizontal balance valves and direct-buried ball valves are required. These valves solve the problem of vertical and horizontal hydraulic imbalance of pipelines, and achieve energy-saving and heat-replacement balance. the goal of.

(3) Valves for environmental protection: In the domestic environmental protection system, the water supply system mainly requires centerline butterfly valves, soft-sealed gate valves, ball valves, and exhaust valves (used to remove air in the pipeline). The sewage treatment system mainly needs soft-sealed gate valves and butterfly valves.

(4) City gas valves: City gas accounts for 22% of the entire natural market. Valves are used in large quantities and have many types. Mainly need ball valve, plug valve, pressure reducing valve, safety valve.

(5) Valves for long-distance pipelines: Long-distance pipelines are mainly crude oil, finished products and natural pipelines. The most commonly used valves for this type of pipeline are forged steel three-piece full bore ball valves, anti-sulfur flat gate valves, safety valves, and check valves.

(6) Valves for petrochemical plants:

a. Oil refining equipment. Most of the valves used in oil refining equipment are pipeline valves, mainly gate valves, stop valves, check valves, safety valves, ball valves, butterfly valves, and traps. Among them, the demand for gate valves accounts for about 80% of the total number of valves. (Valves account for 3%~5% of the total investment of the device).

b. Chemical fiber device. Chemical fiber products mainly include polyester, acrylic and vinylon. The ball valve and jacket valve (jacketed ball valve, jacketed gate valve, jacketed stop valve) of the valve it needs.

　C, acrylonitrile device. The device generally requires valves produced by API standards, mainly gate valves, globe valves, check valves, ball valves, traps, needle valves, and plug valves. Among them, gate valves account for about 75% of the total valve.

d. Synthetic ammonia plant. Due to the different raw ammonia and purification methods, the process flow is different, and the technical performance of the required valve is also different. At present, domestic synthetic ammonia plants mainly need gate valves, globe valves, check valves, traps, butterfly valves, ball valves, diaphragm valves, regulating valves, needle valves, safety valves, high temperature and low temperature valves. Among them, stop valves accounted for 53.4% ​​of the total valve data of the device, gate valves accounted for 25.1%, steam traps accounted for 7.7%, safety valves accounted for 2.4%, regulating valves and cryogenic valves and others accounted for 11.4%.

e. Ethylene plant. Ethylene plant is the leading device of petrochemical industry, which requires a wide variety of valves. Gate valves, globe valves, check valves, and lifting rod ball valves account for the majority, of which gate valves need to be the first. In the "Tenth Five-Year Plan", 6 sets of ethylene plants with an annual output of 660,000 tons need to be built nationwide, and the demand for valves is considerable. In addition, large-scale ethylene and high-pressure polyethylene installations also require ultra-high temperature, lower temperature and ultra-high pressure valve series products.

　F, air separation device. "Air separation" means air separation. The device mainly needs stop valves, safety valves, check valves, regulating valves, ball valves, butterfly valves, and cryogenic valves.

g. Polypropylene device. Polypropylene is a polymer compound made of propylene through polymerization. The device mainly needs gate valves, stop valves, check valves, needle valves, ball valves, and traps.

(7) Valves for power stations: The construction of power stations in my country is developing towards large-scale, so large-diameter and high-pressure safety valves, pressure reducing valves, globe valves, gate valves, butterfly valves, emergency shut-off valves, flow control valves, and spherical seals are needed. Instrument shut-off valve, (according to the national "Tenth Five-Year Plan", in addition to Inner Mongolia and Guizhou provinces can build units with more than 200,000 kilowatts, other provinces and cities can only build units with more than 300,000 kilowatts).

(8) Valves for metallurgy: In the metallurgical industry, the behavior of alumina mainly requires wear-resistant slurry valves (in-flow stop valves) and regulating traps. The steelmaking industry mainly needs metal-sealed ball valves, butterfly valves and oxidation ball valves, stop flash and four-way reversing valves.

(9) Marine flat valves: With the development of offshore oilfield exploitation, the amount of valves required for marine flat hair is gradually increasing. Offshore platforms need to use shut-off ball valves, check valves, and multi-way valves.

(10) Valves for food and medicine: stainless steel ball valves, non-toxic all-plastic ball valves and butterfly valves are mainly used in this industry.

3. Foreign markets. With the entry into WTO, my country's valve market is facing competition from foreign valve manufacturers, and the amount of valves imported from abroad will have a greater growth. At the same time, China's medium and low-end valve products will have more room for production.

(1) Developed countries will buy valves from my country and enter developing countries: The valves that developed countries need to buy from my country are mainly API gate valves, globe valves, check valves, ball valves, butterfly valves, etc.

(2) In the Middle East, Iraq and other countries, oil fields and pipelines are destroyed. Imported oil system and pipeline valves from my country: The oil system valves that the Middle East, Iraq and other countries need to import from my country are mainly gate valves, globe valves, check valves, and long-term valves. The pipelines are mainly flat valves and ball valves.

(3) Conventional import and export companies need to purchase general general purpose valves: most of these general purpose valves are gate valves, globe valves, check valves, ball valves, and butterfly valves.

At present, competition in the valve market at home and abroad is very fierce, especially in the domestic market. The competition between state-owned enterprises and township enterprises and private individual enterprises, coupled with the relative weakening of their purchasing power, has caused some valve companies to face a crisis of survival. At the same time, foreign markets Some opportunities have also led domestic companies to work hard to develop in order to survive. Taking advantage of the opportunity of U.S. sanctions on Iraq and Iran in the Middle East and the favorable export situation, my country's higher quality and cheaper valve products can easily enter the Middle East market and be exported to developed countries. Therefore, all valve companies should seize the opportunity to expand the market and increase exports in response to the needs of the valve market at home and abroad for development.

　3. New valve products that should be developed in China

The development of valve products should be developed around the focus of national economic construction. The focus of my country's "Tenth Five-Year Plan" economic construction is energy, agriculture, environmental protection industry and urban construction. That is to say, the future market of valve products is mainly in the power, petrochemical, fertilizer, environmental protection and urban construction industries. In these industries, valve products to be developed or trial-produced but still need to be improved are mainly:

1. High temperature, high pressure, forged pilot gate valve

2. Forged steel high pressure large diameter globe valve

3. Forged steel high-pressure large-diameter check valve

4. Metal seal, oil seal AVDCO valve

5. Fully welded full bore pipeline ball valve

6. Lifting rod type ball valve

7. Large-caliber emergency cut-off butterfly valve

8. Fully welded direct-buried ball valve

9. High-performance butterfly valve (ANS1 B16.104 grade 6, life span of more than 500,000 times

10. Pilot operated safety valve

11. API 6A flat gate valve

12. API 6A CHOKT2S valve

13. Control flash (regulating valve

14. Adjust the trap

15. Open soft sealing plug valve for refined oil

16. Gate valves and ball valves for deep-sea oil fields (under 3000m on the seabed)

17. High-pressure large-diameter top-mounted ball valve

18. Slurry valve for alumina high pressure melting

19. Natural gas regulating device

In addition, the valve test device also needs to be further improved and developed.

At present, although various manufacturers in my country's valve industry are gradually increasing their research and development efforts, the backwardness of product technology makes competition weak, and the valve varieties produced can only meet about 70% of the market demand. The shortage of low-pressure large-diameter valves, high- and medium-pressure valves whose production and demand are contradictory in varieties and materials, as well as the above-mentioned new products to be developed, require our valve companies to research, develop, and expand. Competition in the market is always the survival of the fittest. Accelerating the adjustment of product structure, technology update, new product development, creation of various brands... is the foundation for the survival, development, and occupation of domestic and foreign markets.
