Which industries need valves?
Valve application industry wide range of user industries, can be divided into petroleum, petrochemical, chemical, metallurgy, electric power, water conservancy, urban construction, machinery, coal, food and other. Among them, mechanical and chemical industry users are the most concerned about the valve market, their requirements for valves are also higher). The largest users of valves are the petrochemical industry, electric power sector, metallurgical sector, chemical industry and urban construction sector. In the application of valve types, machinery, metallurgy, petrochemical, chemical, urban construction and other industries application valve classification is the most. Especially in the mechanical industry, all kinds of valves are basically applied.
In addition to machinery industry, safety valve is mainly used in chemical industry; Butterfly valve is mainly used in petrochemical and metallurgy; Diaphragm valve is mainly used in metallurgy, electric power and chemical industry; Check valve is mainly used in metallurgy, chemical industry and petrochemical; Globe valve is mainly used in petroleum and chemical industry; Closure valve is mainly used in metallurgy, petrochemical, chemical and electric power; Blowdown valve is mainly used in petrochemical and chemical industry; Ball valve is mainly used in petroleum, chemical industry and metallurgy; Gate valve is mainly used in chemical industry, electric power and urban construction; Regulating valve is mainly used in chemical industry, metallurgy, electric power and food; The plunger valve is mainly used in petrochemical and metallurgy; The plug valve is mainly used in chemical industry and metallurgy; Pressure reducing valve is mainly used in petrochemical, chemical and metallurgy; Steam traps are mainly used in chemical and petrochemical industries.
As a general purpose parts, valves are widely used in a variety of industries, but there are three main application purposes in various industries:
1, routine inspection needs; 2. New project supporting facilities; 3. Emergency reserve.
Due to the change of user demand, the market trend of valve products will also change accordingly, in the next period of time, the main development trend is as follows:
1. With the transfer of petroleum development to inland oil fields and offshore oil fields, and the development of power industry from thermal power below 300,000kW to thermal power above 300,000kW, hydropower and nuclear power, valve products should also change their performance and parameters according to the changes in equipment application field;
2. Urban construction system generally uses a large number of low-pressure valves, and to environmental protection and energy-saving development, that is, from the past use of low-pressure iron gate valves gradually to environmental protection rubber plate valve, balance valve, metal seal butterfly valve and middle line seal butterfly valve transition, oil and gas transmission engineering to the direction of pipeline development, which requires a large number of plate gate valves and ball valves;
3. The other side of energy development is energy saving, so from the aspect of energy saving, it is necessary to develop steam traps, and develop to sub-critical and supercritical high parameters;
4. With the development of large-scale construction of power stations, large-caliber and high-pressure safety valves and pressure-reducing valves are needed, as well as quick-opening and closing valves. 5. According to the needs of complete engineering, valve supply from a single variety to multiple varieties and specifications development. There is an increasing tendency for all valves required for an engineering project to be supplied by one valve manufacturer. In the next few years, the overall trend of valve demand for an upward trend, valve this large range of industrial supplies, its demand in stable growth.
Needs large amount of several kinds of valve in the order: ball valves (15.5%), the cut-off valve (12.9%), the relief valve (12.5%), and gate valve (10.6%) (12.5%), butterfly valve, regulator (8.0%) and the check valve (6.1%).
