Flange Carbon Steel Safety Valves are mainly applied to Mainly used in oil and gas, chemical, electric power, metal and combustion gas industries. As overpressure protection equipment. It has high movement precision, good recovery function, fast rotation, and easy operation and maintenance.
Â
1. Good mechanical properties: valves are made of carbon steel, which has high strength and rigidity and can withstand large pressure and temperature. So valves perform well in some demanding working environments.
2. Corrosion resistance: Carbon steel has good corrosion resistance and can be used in a variety of media. For some special corrosive media, additional anti-corrosion measures may be required.
3. The price is relatively low. Compared with some high-alloy steel materials, the cost of carbon steel is lower. A balance is struck between cost and performance.
4. Wide range of applications: Widely used in petrochemical, electric power, pharmaceutical and other industries. It is often used to control the flow and pressure of media such as liquids, gases and steam.
