The distribution of the valve market is mainly based on the construction of engineering projects. The largest users of the valve are petrochemical industry, power sector, metallurgical sector, chemical industry and urban construction sector.
API standard gate valve, globe valve and check valve are mainly used in the petrochemical industry.
The power sector mainly uses high-temperature pressure gate valve, globe valve, check valve and safety valve and a part of the low-pressure butterfly valve, gate valve.
The chemical industry mainly uses the stainless steel gate valve, the globe valve, the check valve.
Metallurgy industry mainly uses low-pressure large-diameter butterfly valve, oxygen globe valve and oxygen ball valve.
Low pressure valve is mainly used in city construction, such as big diameter gate valve in city water pipe, middle line butterfly valve in building and metal seal butterfly valve in city heating The oil pipeline mainly uses the plate gate valve and the ball valve.
Pharmaceutical Industry and food industry mainly used food-grade stainless steel ball valve.
According to the analysis, the main trends in the coming period are as follows 5 points:
1. With the shift of oil development to inland oil fields and offshore oil fields, and the development of the 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, valve products should also be based on the application of equipment changes in their performance and parameters.
2. Urban construction systems generally employ a large number of low pressure valves and are being developed to be environmentally friendly and energy efficient That is, from the past use of low-pressure iron gate valve gradually to environmental protection-type rubber plate valve, balance valve, metal seal butterfly valve and mid-line Seal butterfly valve transition. The development of oil and gas transportation engineering is in the pipeline direction, which needs a lot of flat gate valve and ball valve.
3. The other side of energy development is energy conservation, so in terms of energy conservation, steam traps should be developed and developed to the high parameters of subcritical and supercritical.
4. The construction of power station is developing to large scale, so large diameter and high pressure safety valve and pressure reducing valve are needed as well as quick opening and closing valve.
5. For the requirement of complete engineering, the supply of valves has been developed from single variety to multi-variety and multi-specification. There is a growing trend for all valves required for an engineering project to be supplied by a single valve manufacturer.
No matter how the valve industry develops, the quality of products is the foundation of our development, and the core technology of science is the catalyst of our development.
