Analysis and prospects of China's CR market trend

From 80 onwards, the backbone enterprises in China began to introduce foreign CR products, design, technology and other advanced technology and processing equipment, so that China's CR manufacturing technology and product quality has been improving rapidly. At present, the domestic CR production enterprises have been able to press the ISO international standards, DIN German standard, AWWA American Standard and other international standards for design and manufacture all kinds of CR,some manufacturers of the products reach the international advanced level. Although the overall level of the past few years, the CR industry has been greatly improved, butthe quality is still not stable enough, such as run, run, drip, drain phenomenon often occurs in the domestic CR. In addition, our ability to complete the CR compared with the developed countries there is still a certain gap.

The CR is a low margin product, market competition is very intense. On the distributionof the CR market, mainly based on the construction of the project, the largest user of CR is the petrochemical industry, power sector, metallurgical industry, chemical industry and city construction department. The main application of petrochemical industry standard API gate valve, globe valve and check valve; power sector mainly uses high pressure power station gate valve, globe valve, check valve and safety valve and a low-pressure drain valve butterfly valve, gate valve; chemical industry mainly uses stainless steel gate valve, globe valve, check valve; metallurgical industry the low-voltage large-diameter butterfly valve, oxygen valve oxygen valve; urban construction departmentsmainly low-pressure valve, such as urban water pipeline with large diameter valve, floor apartment building used mainly butterfly valve, urban heating mainly metal sealing butterfly valve; pipeline mainly flat gate valve and ball valve; the pharmaceutical industry mainly uses stainless steel ball valve; food industry mainly uses stainless steel ball valve. CR in the water treatment industry with higher usage, mainly in low-pressure CR products, such as butterfly valve, gate valve, check valve. It is understood that the market has a certain scale CR enterprises have more than 2000, most located inJiangsu and Zhejiang and the Central Plains area. Due to the relatively low technical content products, therefore, competition is more intense.

On the one hand, China's CR products are facing good opportunities for development.With oil development to the mainland and offshore oil fields oil, as well as the power industry under the 300000 kilowatts of thermal power to more than 300000 kilowatts ofthermal power and hydropower and nuclear power development, CR products should be based on changes in device applications and the corresponding changes in its performance and parameters. Urban systems generally use a large number of low voltage CR, and to the development of environmentally friendly and energy-saving, from low iron gate used in the past have gradually shifted the environment-friendly plastic sheet valve, balance valve, metal sealed butterfly valve and the center line butterfly valve seal transition. Oil and gas pipeline projects to develop in the direction, which in turn requires a large number of flat gate valve and ball valve. The other side of energy development is energy conservation, so from the perspective of energy conservation,the development of the steam trap, the development of the high parameter to the sub critical and supercritical.

Power plant construction to large-scale development, so need to use large diameter and high pressure safety valve and pressure relief valve, but also used as a rapid opening and closing CR. Complete the project needs, the CR supply from a single species to multi species and multi standard development. Required for a project to provide all the trend by CR, a CR manufacturers more and more.
