China's valve market analysis and prospects wait

日期:2013/6/10
Since the 1980s, China began to organize similar backbone enterprises to introduce foreign valve product design, technology and other advanced technology and processing equipment, so that our valve manufacturing technology and product quality has been improving rapidly. Currently, the domestic backbone enterprises have been able to produce valves according to ISO international standards, DIN German Standards, AWWA standards and other international standards for American design and manufacture of various valves, some manufacturers of the products has reached the international advanced level. Although in the past few years, the overall level of the valve industry has been greatly improved, but the quality is also not stable enough, such as run, run, drip, drain phenomenon that often appear in the domestic valve. In addition, China is also supporting capacity of the valve compared with developed countries there are still some gaps.
    
Valves are low-margin products, the market is very competitive. The distribution on the valve market, mainly based on the construction of the project, the valve is the largest user of the petrochemical industry, power sector, metallurgy sector, chemical industry and urban construction departments. Petrochemical industry the main application API standard gate, globe and check valves; electricity sector mainly uses high pressure power station gate valve, globe valve, check valve and safety valve and drain valve part to the low-pressure valve, gate valve; chemical industry mainly uses stainless steel gate valve, globe valve, check valve; metallurgical industry mainly uses low-voltage large-diameter butterfly valve, globe valve and oxygen oxygen valve; urban construction department mainly uses low-pressure valve, such as a city water pipe main use of large diameter valve, floor apartment building used mainly midline butterfly, urban heating mainly metal sealing butterfly valve; pipeline mainly flat gate valve and ball valve; pharmaceutical industry mainly uses stainless steel ball valve; food industry mainly uses stainless steel ball valve. Valve in the water treatment industry with higher usage, mainly in low-pressure valve products, such as butterfly valves, gate valves, check valves. It is understood that at present the market with a certain scale valve enterprise with more than 2,000, the majority located in Jiangsu and Zhejiang provinces and the Central Plains area. Due to the relatively low technical content requirements, therefore, more competitive.

    
On the one hand, China's valve products facing good opportunities for development. With oil development to the mainland oil fields and offshore oil fields of the transfer, as well as the power industry from 300,000 kilowatts thermal power to more than 300,000 kilowatts of thermal power and hydropower and nuclear power development, valve products should also be based device applications change corresponding change in its performance and parameters. Urban systems generally use a large number of low-pressure valve, and to the development of environment-friendly and energy-saving, that is, from low-iron gate used in the past have gradually shifted environmentally friendly plastic sheet valve, balance valve, metal sealed butterfly valve and midline sealing butterfly transition. Oil, gas pipeline project to develop in the direction, which in turn requires a lot of flat gate valve and ball valve. Energy development on the other side is the energy, so from the perspective of energy saving, the development of steam traps, and to subcritical and supercritical high parameters development.

    
Power plant construction to large-scale development, so the need to use large diameter and high pressure safety valve and pressure relief valve, but also need to use quickly open and close the valve. Complete project needs, supply valve by a single species to multi-species and multi-standard development. A valve is required for the project by a valve manufacturer to provide all the trend is growing.
