First, from the
valve market as a whole, there are two major:
1, the domestic market, the domestic market was divided into new and expansion projects-way market, maintenance of old equipment, market transformation projects.
Two from the market, general valve serious oversupply of products, followed by business-to-business pressure even with Yang, disorderly competition, counterfeit and inferior ... ..., do not regulate the market, leading to some of the valve manufacturer in the Fierce competition, a significant loss year after year. Two from the needs of the market, with the development of the market economy and improve, in particular the progress of the World Trade Organization (wto), changes in the market of its growing enterprise market by increasing the impact of deep-users in the market The increasing demand for products, product development, production cycle of increasing demand for short.
2, the foreign markets.
In recent years, foreign markets were very active, very intense competition. East Asia and Southeast Asia, the rapid growth of import and export of valves, North America and other developed countries of the European market between the sustainable development of trade, Germany, Italy, Japan, China and other countries and regions to expand exports, the United States, Britain, France and other countries imported High-speed growth, the formation of the international market and prosperity of the valve support points, In addition, due to the further internationalization of the world economy, multinational companies will continue to promote international valve market development, international trade of the region is to become a complete feature.
Second, the domestic market
China's production of valves about three more than 2300, to provide valve product categories, more than 3500 varieties, more than 40,000 specifications.
(1) of the valves used in construction, the city: urban low-pressure systems generally use the valves are currently being environmentally friendly and energy-saving direction. Environment-friendly plastic valves, and the central line of the balance valve butterfly valve, metal seal butterfly valve is gradually replaced by low iron gate. Domestic architecture required for the balance valve multi-valve, sealing the soft valve, butterfly valve, and so on.
(2) cities with heating valve: Urban heat generation system, a great deal of metal seal butterfly valve, and the level of balance valve-buried ball, as a result of this type of vertical pipe valve solution, horizontal hydraulic imbalance to reach energy-saving , On behalf of the heat balance.
(3) environmental protection with valve: the domestic system of environmental protection, water supply systems required the center line butterfly valve, sealing the soft valve, ball valve, the valve (in the pipeline for the exclusion of air). The main sewage treatment system required soft sealing valve, butterfly valve.
(4) with city gas valve: City-wide natural gas market as a whole accounted for 22% of the amount of large valves, which are more types. The main needs of ball valve, Xuan Sefa, the relief valve, safety valve.
(5) long-distance pipeline valves used: long-distance pipelines for crude oil, natural products and no pipeline. This type of pipeline to be the most amount of forged steel valves is a three-wide-body Path
ball valve, flat-sulfur valve, safety valve,
check valve.
(6) petrochemical plant with valve: a, oil refining equipment, oil refining unit of the valves are required pipeline valve, the main valve for the
gate valve, check valve, safety valve, ball valve, butterfly valve, trap Among them,
gate valve to be accounted for about 80% of the total number, (valve devices accounted for a total investment of 3% to 5%). b, chemical fiber equipment, chemical fiber products are polyester, acrylic, vinylon three categories. Its requirement for ball valves, valve jacket (Jacket ball valve, gate valve jacket, jacket cut-off valve). c, clear acrylic device. The device is generally required for the production of standard api valve, the main valve for the cut-off valve, check valve, ball valve, trap, the needle-valve, Xuan Sefa, of which, gate valves accounts for about 75% of the total . d, ammonia plant. Since the original synthetic ammonia and purification methods, the process flow, the valve required technical performance is different. At present, domestic ammonia plant required the main valve, the cut-off valve, check valve, trap, butterfly valve, ball valve, Valves, valve, needle-valve, safety valve, high-temperature low-temperature valves. The cut-off valve by valve devices accounted for 53.4 percent of the total data, accounting for 25.1 percent valve, trap accounts for 7.7 percent, accounting for 2.4 percent safety valve, the valve and the valve from the low temperature and other accounting for 11.4%. E, ethylene plant, ethylene Device is the leading petrochemical plant, which required a wide range of valves.
Valve, the cut-off valve, check valve, ball valve leveraged take-off and landing in the majority, which takes the top gate. "Tenth Five-Year" plan, the country needs to build an annual output of 660,000 tons of ethylene 6 sets of equipment, the considerable demand for valves. In addition, large-scale ethylene and high-pressure polyethylene device needs to use ultra-high temperature, the more low-temperature and high pressure valve product line. f, air separation plant. "Air separation" that is, air separation, the device required cut-off of the main valve, safety valve, check valve, valve, ball valve, butterfly valve, low temperature valves. g, polypropylene unit, polypropylene is easy for the Propylene raw materials, polymer derived from high-molecular compound, which required the main valve device, the cut-off valve, check valve, needle-valve, ball valve, trap.
(7) power station with valve: the Power of China's large-scale construction of a positive direction, it required large-diameter high-pressure and the safety valve, relief valve, globe valve, gate valve, butterfly valves, emergency shut-off valve and flow control valves , Spherical valve sealing instruments, (according to the national "Tenth Five-Year Plan", with the exception of Inner Mongolia and Guizhou provinces can be built more than 200,000 kilowatt generating units, the only other provinces and cities to build more than 300,000 kilowatt generating units).
(8) with metallurgical valve: metallurgical industry required major acts of wear-resistant alumina slurry valve (in-flow valve) to regulate the trap. The main steel-making industry required sealed metal ball valve, butterfly valve and ball valve oxidation, as flash and reversing valve.
(9) combined Marine-valve: With the exploitation of offshore oil field development, and its ocean-valve made of the required amount gradually increased. Ocean off the platform needed ball, a non-return valve, multi-way valve.
(10) Food and Drug use valve: the industry's main stainless steel ball valve required, non-toxic plastic ball and butterfly valves.
3, foreign markets. With access to wto,
China valve market is facing foreign competitors valve, the valve of imports from abroad will have a greater amount of growth, at the same time, the Chinese, low-grade products, valves, there will be much more room .
(1) China's purchase of valves from developed countries to developing countries: China from the developed countries need to buy the valves, api for the main valve, the cut-off valve, check valve, ball valve, butterfly valve, and so on.
(2) in the Middle East, Iraq and other countries, oil fields, pipelines from the destruction of China's imported oil pipeline systems and valves used: the Middle East, Iraq and other countries need to import oil from our system, with the main valve for the valve, the cut-off valve, check valve, The main long-distance pipelines and valves for flat-panel ball.
(3) the conventional import and export companies in general need to buy the common valve: common type of valve from the valve, the cut-off valve, check valve, ball valve, butterfly valve majority.
At present, domestic and international valve market is very intense competition, particularly in the domestic market, state-owned enterprises and township enterprises and private individual competition, combined with the relative purchasing power weakened, some of the valves so that enterprises are facing a crisis of survival, at the same time, foreign Some of the market opportunities and lead to domestic enterprises in order to survive efforts to open up. By the United States in the Middle East Iraq, Iran sanctions and export opportunities for the good of the situation, China's high quality, cheaper products, valves, it is easy to break into the market in the Middle East, exports to developed countries. As a result, all of the valves business, should seize the opportunity for domestic and international valve market demand and expand markets, increase exports in order to develop.
Third, the domestic development of the valve should be new products
Valve product development should focus on building the country's economic development to focus on. China's "Tenth Five-Year" will focus on economic construction, energy, agriculture, industry and environmental protection, urban construction, that is, valve products in the future the main market in electricity, petrochemicals, fertilizers, environmental protection and urban construction and other industries. These industries are yet to be developed or trial, but also improve the quality of the products of the main valves are:
1, high-temperature, high pressure, forging the pilot-valve
2, large-diameter high-pressure steel valve
3, large-diameter high-pressure steel check valve
4, metal seal, valve oil seals avdco
5, full-diameter pipe welding wide-Ball
6, the ball landing leveraged
7, large diameter butterfly valve to cut off emergency
8, all-welded-buried ball
9, high-performance butterfly valve (ans1 b16.104 6-class, life together as much as 50 million more than
10, the pilot-type safety valve
11, api 6a plate valve
12, api 6a chokt2s valve
13, flash control (valve)
14, regulation trap
15, refined oil Distraction with soft-sealing Xuan Sefa
16, with deep-sea oil field (3000m below the seabed) valve, ball valve
17, large-diameter high-pressure coat-ball
18, high-pressure aluminum melt using a slurry valve
19, natural gas conditioning devices
In addition, the valve test device is also subject to further enhance the development.
At present, China's valve industry, despite the manufacturer is gradually increased research and development efforts, but the technology behind the product, making not effective competition, production of valves varieties to meet market demand, only 70%. The shortage of low-pressure valves and large-caliber production and demand contradiction in the variety and texture on the high and medium pressure valve, there is the question of the development of new products, we need the old valve Enterprise Institute is to develop and expand. Competition in the market, will always be the survival of the fittest. To speed up the adjustment of product structure, technology updates, new product development, the creation of the card ... ... is the survival of their enterprises, development of the market accounted for the foundation of domestic and foreign markets.
