What is the trend of industrial valve application?
Based on the construction and engineering of projects, the largest users of valves are oil &gas, petrochemical industry, power sector, metallurgical industry, chemical industry and urban construction department.
S/N | Application | Main Valves |
1 | Oil & gas | slab gate valve and fully welded ball valve |
2 | Petrochemical | API standard gate valves, globe valves and check valves |
3 | power sector | high-temperature pressure gate valves, globe valves, check valves and safety valves for power stations ; some low-pressure butterfly valves and gate valves for water supply and drainage valves |
4 | Chemical | Stainless steel gate valve, globe valve, check valve |
5 | metallurgical industry | low pressure large diameter butterfly valve, oxygen shutoff valve and oxygen ball valve |
6 | urban construction | Low pressure valves, such as urban tap water pipeline mainly adopts large diameter gate valve; building construction mainly adopts middle line Butterfly valve; urban heating mainly uses metal sealing butterfly valve |
7 | pharmaceutical industry | stainless steel ball valve |
8 | food industry | stainless steel ball valve |
Regarding the market trend of valve products, the main trends in the future are as follows:
1. With the oil development to inland oilfields and offshore oil fields, and the development of power industry from thermal power of less than 300,000 kilowatts to thermal power and hydropower and nuclear power of more than 300,000 kilowatts, performance and parameters of valve products should also be changed according to changes in equipment application fields.
2. Oil and gas transmission projects are developing in the direction of pipelines, which in turn requires a large number of slab gate valves and ball valves.
3. The other side of energy development is energy conservation, so from the perspective of energy conservation, high performance steam traps should be developed for subcritical and supercritical services.
4. The construction of the power station is going to be large-scale, so it is necessary to use large-diameter and high-pressure safety valves and pressure reducing valves, as well as fast opening and closing valves.
5. Urban construction systems generally use a large number of low-pressure valves, featuring in the development of environmentally friendly and energy-saving application. The low-pressure iron gate valve used in the past has gradually turned to environmentally friendly rubber plate valves, balancing valves, metal sealing butterfly valves and mid-line sealing butterfly valves.
6. For the needs of complete sets of projects, the supply of valves has evolved from a single variety to multiple varieties and specifications. The valve required for an engineering project is increasingly being solo provided by a valve manufacturer.
