Power station valve market situation

Since the 1980s, China has begun to organize key enterprises to introduce advanced technologies and processing equipment such as the design and technology of foreign valve similar products, so that China's valve manufacturing technology and product quality have been rapidly improved. At present, the domestic valve production backbone enterprises have been able to design and manufacture various valves in accordance with international standards such as ISO International Standard, DIN German Standard, and AWWA American Standard. Some manufacturers' products have reached the international advanced level. Although the overall level of the valve industry in the past few years has been greatly improved, but the quality is not yet stable, such as run, run, drip, leakage phenomenon often occurs in domestic valves. In addition, hard-sealed butterfly valve ball valve safety valve valve stainless steel valve hydraulic control valve safety valve sales anti-theft valve China's valve supporting capacity is also compared with developed countries there is still a certain gap.

Valves are products with low profit margins and the market is highly competitive. The distribution of the valve market is mainly based on the construction of the project. The largest users of the valve are the petrochemical industry, the power sector, the metallurgy sector, the chemical industry and the urban construction sector. The petrochemical industry mainly uses gate valves, globe valves and check valves of API standards; the power sector mainly adopts low-pressure butterfly valves and gate valves for power station high-temperature pressure gate valves, globe valves, check valves, and safety valves and some of the water supply and drainage valves; the chemical industry mainly adopts them. Stainless steel gate valve, globe valve and check valve; the metallurgical industry mainly uses low-pressure large-diameter butterfly valve, oxygen globe valve and oxygen ball valve; the urban construction department mainly adopts low-pressure valves, such as urban tap water pipelines mainly adopt large-diameter gate valves, and Louyu construction adopts the middle line. The butterfly valve, the city heating mainly uses the metal seal butterfly valve; The oil pipeline mainly uses the flat gate valve and the ball valve; The pharmaceutical industry mainly uses the stainless steel ball valve; The food industry mainly uses the stainless steel ball valve and so on. The valve is used in a large amount in the water treatment industry, mainly in low pressure valve products such as butterfly valves, gate valves, and check valves. It is understood that there are more than 2,000 valve companies with a certain scale on the market, most of which are located in Jiangsu, Zhejiang and Central Plains. Due to the relatively low technical content of products, the competition is even fiercer.

On the one hand, China's valve products are facing a good opportunity for development. With the shift from oil development to oil fields in the interior and offshore oil fields, and the development of thermal power and hydropower and nuclear power from 300,000 kilowatts to less than 300,000 kilowatts in the power industry, valve products should also change their performance in response to changes in equipment applications. parameter. Urban construction systems generally use a large number of low-pressure valves, and are developing towards environmental protection and energy-saving, that is, the low-pressure iron gate valves used in the past have gradually shifted to environmental-friendly rubber sheet valves, balancing valves, metal sealing butterfly valves and midline sealing butterfly valves. The development of oil and gas transmission projects in the direction of pipelines requires a large number of flat gate valves and ball valves. The other side of energy development is energy conservation. Therefore, from the aspect of energy conservation, we need to develop steam traps and develop them to subcritical and supercritical high parameters.

The development of the power station is becoming large-scale. Therefore, large-diameter and high-pressure safety valves and pressure reducing valves are required. At the same time, valves must be opened and closed quickly. The needs of complete sets of projects, valve supply from a single species to more varieties and more specifications. The need for a valve for an engineering project is increasingly provided by a valve manufacturer.
