What Kinds of Valves are Used in Different Industries?
Urban Gas
Urban gas accounts for 22 percent of the total natural gas market, with many types and large volumes of valves. Ball valves, plug valves, pressure relief valves, and relief valves are often required.
Urban heat supply
A large number of metal-sealing butterfly valves, horizontal balancing valves, and directly buried ball valves are needed in the urban heat supply system, this is because these valves can solve the pipe vertical and horizontal hydraulic imbalance, so as to achieve energy-saving and heat balance.
Urban architecture
Low-pressure valves are generally used in urban construction system, which is developing towards environmental protection and energy saving. Environment-friendly glue plate valves, balance valves, middle line butterfly valves, and metal seal butterfly valves are gradually replacing low-pressure iron gate valves.
Environmental protection
In the environmental protection system, the middle line butterfly valve, the soft seal gate valve, the ball valve, the exhaust valve (used to expel the pipeline air) are mainly needed in the water supply system, while the soft seal gate valve and butterfly valve are mainly used in the sewage treatment system.
Long-distance transport pipeline
The long-distance pipeline is mainly crude oil, finished product, and natural pipeline. The valves used in most of these pipelines are forged steel three-piece full-size ball valves, sulfur resistant plate gate valves, safety valves, and check valves.
Petrochemical equipment
* Oil refining facility
Most valves used in oil refining facilities are pipeline valves, mainly gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, and steam traps. Among them, the gate valve demand accounts for about 80% of the total number of valves (valves account for 3% ~ 5% of the total investment of the device).
* Chemical fiber plant contraction
Chemical fiber products are mainly polyester, acrylic, and polyvinylidene in three categories, the main valve are the ball valve, and jacket valve (jacket ball valve, jacket gate valve, jacket globe valve).
* Acrylonitrile device
This device generally needs the valve produced by API standard, mainly including a gate valve, globe valve, check valve, ball valve, trap valve, needle valve, and plug valve, among which gate valve accounts for about 75% of the total valve.
* Synthetic ammonia equipment
Due to the synthesis of ammonia and purification methods, the process is different and the required valve technical performance is also varied. At present, the ammonia synthesis device mainly needs to use a gate valve, globe valve, check valve, trap valve, butterfly valve, ball valve, diaphragm valve, regulating valve, needle valve, safety valve, and high and low-temperature valve.
Power station
The construction of the power stations is now developing towards a large scale, so large diameter and high-pressure safety valves, pressure reducing valves, globe valves, gate valves, butterfly valves, emergency cut-off valves, flow control valves, and globe sealing instrument globe valve are needed.
Metallurgy
In the metallurgical industry, abrasive slurry valves (inflow stop valves) and regulating steam traps are mainly needed. The metal-sealed ball valves, butterfly valves and oxidation ball valves, globe valves, and four-way reversing valves are mainly used in the steel-making industry.
Ocean platform
With the development of offshore oil field exploitation, the number of valves needed for offshore development is increasing gradually. Offshore platforms shall use shutoff ball valves, check valves, and multiway valves.
Food and pharmaceutical industries
Stainless steel ball valves, non-toxic plastic ball valves, sanitary ball valves, sanitary diaphragm valves, and sanitary butterfly valves are mainly needed in the food and pharmaceutical industries.
In the above 10 kinds of valve products, the demand for the general valve is more than that for the instrument valve, needle valve, gate valve, globe valve, check valve, ball valve, and butterfly valve.
