Valve industry development status and product updates

1. valve market characteristics at home and abroad from the valve market as a whole, there are two main: 1, the domestic market, the domestic market is divided into new, expansion project market, the old device maintenance, transformation project market.


1. domestic and foreign valve market characteristics

From the valve market as a whole, there are two main:

1, the domestic market, the domestic market is divided into new construction, expansion project market, old device maintenance, transformation project market.

From the two market point of view, the general valve products serious oversupply, secondly, between enterprises actually oppressed, disorderly competition, fake and shoddy ......, the market is not standardized, resulting in some valve manufacturers in the fierce competition, years of substantial losses. From the demand of these two markets, with the development and improvement of the market economy, especially the progress of the World Trade Organization (WTO), its market changes more and more, enterprises are more and more deeply influenced by the market, the user's demand for market products is getting higher and higher, and the demand for product development and production cycle is getting shorter and shorter.

(2) Foreign markets. Foreign markets are very active in recent years, the competition is quite fierce. The rapid growth of valve import and export in East Asia and Southeast Asia, the continuous development of market trade between developed countries such as the European Community in North America, the expansion of exports from Germany, Italy, Japan, China and other countries and regions, and the rapid growth of imports from the United States, Britain, France and other countries have formed the support point for the prosperity of the international valve market. Furthermore, 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 is another major feature of Bi has become.

2. domestic market

China's valve production of three about more than 2300, can provide valve products have several categories, more than 3500 varieties, more than 40000 specifications.

(1) urban construction valves: urban construction systems generally use low-pressure valves, and are currently developing in the direction of environmental protection and energy saving. Environmentally friendly rubber plate valve, balance valve and the middle line butterfly valve, metal seal butterfly valve is gradually replacing the low-pressure iron gate valve. Domestic city buildings need to use the valve for the balance valve, soft seal gate valve, butterfly valve and so on.

(2) city heating valves: urban generation of heat system, need to use a large number of metal sealing butterfly valve, horizontal balance valve and buried ball valve, because this kind of valve to solve the pipeline longitudinal, transverse hydraulic imbalance problem, to achieve energy saving, generation of heat balance.

(3) Environmental protection valves: In the domestic environmental protection system, the water supply system mainly needs to use the middle line butterfly valve, soft seal gate valve, ball valve and exhaust valve (used to exclude the air in the pipeline). Sewage treatment system mainly needs to use soft seal gate valve, butterfly valve.

(4) City gas valves: City gas accounts for 22% of the entire natural market, large amount of valves, and many of their 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. This kind of pipeline needs the most amount of the valve is forged steel three body full bore ball valve, anti sulfur flat gate valve, safety valve, check valve.

(6) Valves for petrochemical plants:

A, oil refining equipment, oil refining equipment required valves are mostly pipeline valves, mainly for gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, traps, of which, gate valve demand accounted for about 80% of the total number of valves, (valves accounted for 3% to 5% of the total investment).

B, chemical fiber device, chemical fiber products are mainly polyester, acrylic, vinylon three categories. The required valve ball valve, jacket valve (jacket ball valve, jacket gate valve, jacket stop valve).

C, acrylic unit. The device generally requires API standard production of valves, mainly for the gate valve, globe valve, check valve, ball valve, trap, needle valve, plug valve, which, the gate valve accounted for about 75% of the total valve.

d. ammonia plant. Due to the different synthetic ammonia and purification methods, the process is different, the technical performance of the required valve is also different. At present, the domestic ammonia plant mainly need to use gate valve, globe valve, check valve, trap, butterfly valve, ball valve, diaphragm valve, regulating valve, needle valve, safety valve, high temperature and low temperature valve. Among them, cut-off valves account for 53.4 per cent of the total data of valves used in the device, gate valves account for 25.1 per cent, traps account for 7.7 per cent, safety valves account for 2.4 per cent, and control valves and low-temperature valves and others account for 11.4 per cent.

E, ethylene plant, ethylene plant is the leading device of petrochemical industry, its need for a wide range of valves. Gate valves, globe valves, check valves, lift rod ball valves account for the majority, of which gate valves need to be the first. "Tenth Five-Year Plan", the country also needs to build an annual output of 660000 tons of ethylene plant 6 sets, the valve demand is considerable. In addition, large ethylene and high-pressure polyethylene devices also need to use ultra-high temperature, lower temperature and ultra-high pressure valve products.

f. Air separation unit. "Air separation" that is air separation, the device mainly need to use cut-off valve, safety valve, check valve, regulating valve, ball valve, butterfly valve, low temperature valve.

G, polypropylene device, polypropylene is easy to propylene as raw material, the polymerization of polymer compounds, the device mainly need to use gate valve, globe valve, check valve, needle valve, ball valve, trap.

(7) Valves for power stations: The construction of power stations in China is developing towards large-scale, so large-diameter and high-pressure safety valves, pressure reducing valves, stop valves, gate valves, butterfly valves, emergency cut-off valves, flow control valves and spherical sealed instrument stop valves are required (according to the national "Tenth Five-Year Plan", except for Inner Mongolia and Guizhou provinces, units of more than 200000 kilowatts can be built, other provinces and cities can only units of more than 300000 kilowatts).

(8) metallurgical valves: the behavior of alumina in the metallurgical industry mainly needs wear-resistant slurry valve (in the flow cut-off valve), regulating the trap. The steel industry mainly needs metal sealing ball valve, butterfly valve and oxidation ball valve, stop flash and four-way reversing valve.

(9) the ocean flat with the valve: with the development of offshore oil field exploitation, the amount of the ocean flat need to use the valve is also gradually increasing. Offshore platforms require shut-off ball valves, check valves and multi-way valves.

(10) food and medical valves: the industry mainly needs stainless steel ball valve, non-toxic plastic ball valve and butterfly valve.

3. Foreign markets. With the entry into the WTO, China's valve market is facing competition from foreign valve manufacturers, the amount of imported valves from abroad will have a larger growth, at the same time, China's medium and low-grade valve products, the product will have more space.

(1) developed countries will buy valves from China into developing countries: developed countries need to buy valves from China, 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 were destroyed. Oil systems and pipeline valves imported from China: valves for oil systems imported from China in the Middle East, Iraq and other countries are mainly gate valves, globe valves, check valves, long-distance pipelines are mainly flat valves and ball valves.

(3) regular import and export companies need to buy general general valves: this type of general valves from gate valves, globe valves, check valves, ball valves, butterfly valves mostly.

At present, the domestic and foreign valve market competition is very fierce, especially in the domestic market, state-owned enterprises and township enterprises and private individual enterprises between the competition, coupled with the relative weakening of its purchasing power, so that some valve enterprises are facing the crisis of survival, at the same time, some opportunities in foreign markets, but also led to domestic enterprises in order to survive to strive to develop. Taking advantage of the United States' sanctions on Iraq and Iran in the Middle East and the optimistic export situation, my country's high-quality and low-cost valve products can easily enter the Middle East market and export to developed countries. Therefore, all valve companies should seize the opportunity to expand the market and increase exports in response to the needs of domestic and foreign valve markets in order to develop.

3. domestic should develop new products of the valve

The development of valve products should focus on the development of national economic construction. The focus of China'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 mainly in electric power, petrochemical, fertilizer, environmental protection and urban construction industries. And these industries, to be developed or trial production but also need to improve the quality of the valve products 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 diameter emergency cut-off butterfly valve

8. Fully welded directly buried ball valve

9. High-performance butterfly valve (ANS1 B16.104 Grade 6, with a life span of more than 500000 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 drain valve

15. Open soft sealing plug valve for refined oil

16. Gate valve and ball valve for deep-sea oil field (seabed below 3000m)

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

18. Slurry valve for high pressure melting out of alumina

19. Natural gas regulating device

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

At present, although China's valve industry manufacturers are gradually increasing scientific research and development efforts, but the product technology behind, making the competition is not effective, the production of valve varieties can only meet the market demand of about 70%. The shortage of low-pressure large-diameter valves, high-pressure valves with production and demand contradictions in varieties and materials, as well as the above-mentioned new products to be developed, all need our valve enterprises to study, develop and expand. Competition in the market is always the survival of the fittest. Speed up the adjustment of product structure, technology updates, the development of new products, the creation of the brand ...... is the enterprise's own survival, development, the foundation of the market at home and abroad.
