First, the characteristics of domestic and international
valve market
The entire
valve from the market point of view, there are two-fold:
1, the domestic market, the domestic market was divided into new, expanding market agenda item, the old equipment maintenance, market transformation projects.
Judging from the two markets, a serious oversupply of ordinary valve products, and secondly, even with pressure between Yang and disorderly competition, fake ... ..., the market is not standardized, resulting in the production of certain valves in severe competition and has been suffering significant losses. From the two market demands, with the market economy development and improvement, in particular the progress of World Trade Organization (WTO), its changes in the market, more and more, businesses are increasingly affected by the market depth, the user of the market increasing demand for product development, the needs of the production cycle becoming shorter and shorter.
2, foreign markets. Foreign markets were very active in recent years, fierce competition. East and Southeast Asia the rapid growth of import and export of valves, North America and other developed countries of the European Community 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 valve market, the strong point of prosperity, In addition, as a result of further internationalization of the world economy, multinational companies will continue to promote the international valve market development, international trade areas is another major characteristic of Bi.
Second, the domestic market
Valve production in China of about 3 over 2300, the valve can provide a few broad categories of products, more than 3500 species, more than 40,000 specifications.
(1) city of valves used in construction: urban systems generally use the low-pressure valves, are currently being environmentally friendly and energy-saving direction. Environment-friendly plastic valve, balance valve and the center line
butterfly valve, metal sealed butterfly valve is gradually replaced by low-pressure valve iron. Urban construction required for the balance valve valve, soft sealing
gate valve, butterfly valve and so on.
(2) urban heat with valve: City-generation thermal system, a great deal of metal sealed butterfly valve, the level of balance valve and direct-buried-type
ball valve, the valve to solve this kind of vertical piping, horizontal hydraulic imbalance, to achieve energy-saving , on behalf of the purpose of thermal equilibrium.
(3) environmental protection with valve: the domestic environmental protection system, water supply system is mainly required of Center Line butterfly valve, soft sealing gate valve, ball valve, exhaust valve (for exclusion of the air pipe). Sewage disposal system required soft seal
gate valve,
butterfly valve.
(4) use of city gas valve: City-wide natural gas accounted for 22% of the market, the amount of the valve, and also its type. The main need for ball valves,
plug valves, pressure relief valve, safety valve.
(5) long-distance pipeline with valve: long-distance pipeline is mainly crude oil, and natural product line did not. Most of these pipelines will take the amount of forged steel valves are three-body Full Bore
Ball Valve, sulfur flat gate valve, safety valve,
check valve.
