Imported valves, domestic valves, valve maintenance, market analysis
From the entire valve market point of view, mainly two:
1, the domestic market, the domestic market is divided into new, expanded agenda item the market, the old equipment maintenance, reconstruction project market. Steam solenoid valve imported from two market point of view, a serious oversupply of ordinary valve product, and secondly, between enterprises race to pressure Yang and disorderly competition, fake ... ..., the market is very standardized, cause some valve Door manufacturing enterprises in the fierce competition, substantial losses year after year. Market demand from two terms, with the development of market economy and improvement of, in particular the progress of the World Trade Organization (WTO), its changes in the market increases, the impact of enterprises subject to market more and more deeply, the user on the market increasing demand for the product, to product development, increasing demand for shorter production cycle.
2, foreign markets. Imported pneumatic valve is very active in foreign markets, in recent years, competition is fierce. East and Southeast Asia import and export of valves rapid growth in North America, European Union and other developed countries the sustainable development of inter-market trade, Germany, Italy, Japan, China and other countries and regions, export expansion, the United States, Britain, France and other countries imported rapid growth, forming the anchor of the international valve market boom Moreover, due to the further internationalization of the world economy, multinational companies will continue to promote international valve market development, international trade regionalization is completed be another feature.
Second, the domestic market in China is about more than 2300 valve produced three imported valve pneumatic valve can provide several product categories, over 3500 varieties, more than 40,000 specifications.
(1) City Building valves: Urban systems are generally low-pressure valves, are currently being environment-friendly and energy-saving direction. Environment-friendly plastic sheet valve, balance valve, and the center line butterfly valve, metal sealed butterfly valve is gradually replaced by low iron gate. You need to use the domestic urban architecture, mostly valve balancing valve, soft seal gate valve, butterfly valve and so on.
(2) urban heat with the valve: City on behalf of the thermal system, which requires large amounts of metal sealing butterfly valve, horizontal balancing valve and the burial-type ball valve, which are the valves to solve pipe vertical, horizontal hydraulic imbalance to achieve energy-saving , on behalf of the heat balance purposes.
(3) environmentally-friendly Valves: Taiwan''''s environmental systems, water supply system is mainly need to use the center line butterfly valve, soft seal gate valve, ball valve, exhaust valve (used to exclude the air pipe). You need to use sewage treatment system is mainly soft sealing gate valve, butterfly valve. (4) The city gas with the valve: City''''s total natural gas market, 22% of the whole, valves use large, its type is also more. The key needs of valve, plug valves, pressure reducing valve, safety valve.
(5) long-distance pipeline with the valve: long-distance pipeline is mainly crude oil, finished products and natural pipeline did not. Majority of these pipelines need to use the valve is a three-body Forged Steel Full Bore Ball Valve, anti-sulfur flat gate valve, safety valve, check valve.
(6) petrochemical plant with the valve: a, oil refining equipment, oil refining equipment are mostly need to use the valve pipe valve, mainly valve, globe valve, check valve, safety valve, ball valve, butterfly valve, steam trap Among them, the total number of gate valves need to account for about 80%, (the valve unit of the total investment accounted for 3% ~ 5%). b, chemical equipment, chemical fiber products are polyester, acrylic, PVA three categories. The need to use the ball valve, jacket valve (jacketed ball valve, jacketed valve, jacketed valve). c, acrylonitrile unit. The device is a general need to use API standard production of valves, mainly valve, globe valve, check valve, ball valve, steam traps, needle valves, plug valves, of which gate valves accounted for about 75% of the total . d, ammonia plant. Since the original synthetic ammonia and purification methods, the process is different from the required technical performance of the valve are also different. At present, the domestic ammonia plant need to use the main gate valve, globe valve, check valve, trap, butterfly valve, ball valve, diaphragm valves, regulating valves, needle valve, safety valve, high temperature and low temperature valves. Among them, cut-off valve valve devices accounted for 53.4% of the total data, gate valve, at 25.1%, trap 7.7%, 2.4% safety valves, regulating valves and cryogenic valves, and other accounts from 11.4%. E, ethylene, ethylene device is the leading petrochemical installations, which need to use a wide range of valves. Gate valve, globe valve, check valve, lift rod ball the majority of them need to Jushou valve. "Tenth Five-Year Plan", the country needs to build an annual output of 660,000 tons of ethylene unit 6 sets of considerable demand for its valves. In addition, large-scale ethylene and high-pressure polyethylene plant needs to use ultra-high temperature, the more low temperature and high pressure valve product line. f, air separation plant. "Empty hours" that is, air separation, the device mainly need to use cut-off valve, safety valve, check valve, regulating valve, ball valve, butterfly valve, cryogenic valves. g, polypropylene unit, polypropylene, propylene as raw materials is easy, after polymerization of polymers, the device need to use the main gate valve, globe valve, check valve, needle valve, ball valve, trap.
(7) power plant valves: China power plant building in the forward direction of the development of large-scale, so need to use large-diameter and high pressure safety valve, reducing valve, globe valve, gate valve, butterfly valves, emergency shut-off valve and flow control valves , spherical sealing instrument cut-off valve, (in accordance with national "Tenth Five-Year Plan", with the exception of Inner Mongolia and Guizhou provinces, but also builds an additional 20 million kw generating units, all other provinces and cities can only build 300 thousand kilowatts or more units).
(8) metallurgical valve: metallurgical industry, the main need to use wear behavior of alumina slurry valve (in-flow valve) to regulate the trap. You need to use steel-making industry, the main metal sealing ball valve, butterfly and oxidation ball valve, stop flashing, and reversing valve.
(9) Ocean level combination valve: With the exploitation of offshore oilfield development, the need to use valve made of marine-ping volume gradually increased. You need to use offshore platform off valve, check valve, multi-way valve.
(10) Food and Drug Administration to use the valve: the industry''''s major need to use stainless steel ball valve, non-toxic plastic ball and butterfly valves.
3, foreign markets. As the access to WTO, China''''s valve market is facing competition from abroad, the valve manufacturer, import valve valve imported from abroad, the company will have a large amount of growth, at the same time, China''''s middle and low-grade valve product, producers will be have more space.
(1) the developed countries will be China''''s purchase of the valve into the developing countries: developed countries need to buy valves from China, mainly API gate valve, globe valve, check valve, ball valve, butterfly valve and so on.
(2) Middle East, Iraq and other countries, oil fields, pipelines were destroyed China''''s oil imports from the system and the Pipeline Valves: Middle East, Iraq and other countries need to import oil from our systems primarily for valve gate valve, globe valve, check valve, long-distance pipeline is mainly flat valves and ball valves.
(3) The regular import and export companies in general need to purchase a common valve: the valve from the common type of gate valve, globe valve, check valve, ball valve, butterfly valve majority. At present, the domestic and international valve market competition is very intense, particularly in the domestic market, state-owned enterprises and township and village enterprises and private individuals of competition between enterprises, coupled with the relative weakening of their purchasing power, so that enterprises are facing a number of valves to survive the crisis at the same time, foreign some of the opportunities the market has also led to the efforts of domestic enterprises to open up in order to survive. By the United States in the Middle East, Iraq, Iran, sanctions, promising opportunities and export situation of China''''s higher quality, cheaper valve product, it is easy to enter the Middle East market, exports to developed countries. Therefore, all the valves enterprises should seize the opportunity to address the needs of domestic and international valve market, expand markets, increase exports, in order to develop. Third, the domestic new products should be developed valve valve product development should focus on the focus of national economic construction to develop.
China''''s "15" will focus on economic construction, energy, agriculture, environmental protection industry and urban construction, that is, valve products, future market, mainly in electricity, petrochemicals, fertilizers, environmental protection and urban construction and other industries. These industries, to be developed or are in trial, but needs to improve the quality of valve products are mainly as follows: 1, high temperature, high pressure, forging a pilot-valve 2 Forged high-pressure large-diameter cut-off valve 3, forged high-pressure large-diameter only return valve 4, metal seals, oil seals AVDCO valve 5, all welding Full Bore Pipeline Ball 6, 7 ball lift rod, large diameter butterfly valves for emergency cut eight, full welded ball valve 9 Buried, high-performance butterfly Valves (ANS1 B16.104 6 level, Shou combined 50 million times more than 0, pilot-type safety valve 11, API 6A gate valve plate 12, API 6A CHOKT2S valve 13 to control the flash (control valve) 14 to regulate the steam trap 15, refined oil with the distraction-type soft sealing plug valves 16, deep-sea oilfield (3000m below seabed) gate valve, ball valve 17, high-pressure large-diameter ball 18-style coat, alumina high-pressure melting out with the slurry valve 19, gas conditioning In addition, the valve testing equipment has yet to be developed further enhanced. At present, despite China''''s valve industry, manufacturers are gradually increasing the research and development efforts, but the product of outdated technology, making competition does not force, the production of valve types can only be to meet the market demand for around 70%. a shortage of low-pressure large-diameter valves and production and demand problem in the variety and texture on the high and medium pressure valves, as well as the above-mentioned new products to be developed, all we need to study real old valve business, development and expansion. market competition is always survival of the fittest. to speed up the adjustment of product structure, technology updates, new product development, the creation of the brand ... ... is the enterprise''''s own survival, development, accounting for farm domestic and international markets to survive."> |
