Five major trends in the development of the valve product market
The distribution of the valve market is mainly based on the construction of engineering projects. The largest users of valves are the petrochemical industry, power sector, metallurgical sector, chemical industry and urban construction sector. The petrochemical industry mainly uses API standard gate valves, globe valves and check valves; the power sector mainly uses high-temperature pressure gate valves, globe valves, check valves and safety valves for power stations and some low-pressure butterfly valves and gate valves for water supply and drainage valves; the chemical industry mainly uses Stainless steel gate valves, stop valves, and check valves; the metallurgical industry mainly uses low-pressure large-diameter butterfly valves, oxygen shut-off valves and oxygen ball valves; urban construction departments mainly use low-pressure valves, such as urban water pipelines mainly use large-diameter gate valves, and building construction mainly uses mid-line For butterfly valves, metal-sealed butterfly valves are mainly used for urban heating; flat gate valves and ball valves are mainly used for oil pipelines; stainless steel ball valves are mainly used in the pharmaceutical industry; stainless steel ball valves are mainly used in the food industry.
Regarding the market trend of valve products, according to analysis, the main trends in the future are as follows:
1. With the transfer of petroleum development to inland oil fields and offshore oil fields, and the development of the power industry from thermal power below 300,000 kilowatts to thermal power, hydropower and nuclear power above 300,000 kilowatts, valve products should also be changed according to changes in equipment application fields. Performance and parameters.
2. Urban construction systems generally use a large number of low-pressure valves, and are developing towards environmental protection and energy-saving, that is, the transition from low-pressure iron gate valves used in the past to environmentally-friendly rubber plate valves, balance valves, metal seal butterfly valves, and centerline seal butterfly valves. The development of oil and gas transportation projects in the direction of pipelines requires a large number of flat gate valves and ball valves.
3. The other side of energy development is energy conservation, so from the perspective of energy conservation, steam traps should be developed and developed towards subcritical and supercritical high parameters.
4. The construction of power stations is developing towards large-scale development, so large-diameter and high-pressure safety valves and pressure reducing valves are required, and fast opening and closing valves are also required.
5. For the needs of a complete set of projects, the supply of valves has developed from a single variety to multiple varieties and specifications. There is an increasing trend that the valves required by an engineering project are all provided by a valve manufacturer.
