China Gate Valve Material Classification
As a key component in a fluid control system, the material selection of the china gate valve directly affects its performance and scope of application. In the Chinese market, gate valves are mainly divided into the following categories based on the material:
اس کے علاوہ, copper gate valves اور plastic gate valves are also used in specific fields. Copper gate valves are mainly used in seawater desalination, food processing and other occasions with high requirements for thermal conductivity and corrosion resistance. Plastic gate valves have found a place in the chemical, pharmaceutical and other industries due to their lightweight and corrosion resistance.
Carbon steel gate valve is one of the most common types. This type of gate valve uses carbon steel materials such as WCA, WCB, WCC, LCB, وغیرہ, and is suitable for working conditions with a temperature range of -46°C to 425°C. Carbon steel gate valves are widely used in the petroleum, کیمیائی, and power industries due to their low cost, high strength, and good processing performance.
Stainless steel gate valve stands out for its excellent corrosion resistance. Commonly used stainless steel grades include 301, CF8 (equivalent to 304 سٹینلیس سٹیل), CF8M (equivalent to 316 سٹینلیس سٹیل), وغیرہ. These materials can maintain good performance in the extreme temperature range of -198°C to 816°C, and are particularly suitable for occasions where highly corrosive media are handled, such as the chemical and pharmaceutical industries.
Low alloy steel gate valve (especially chromium-molybdenum steel) performs well in high temperature applications. Typical grades such as ZG1Cr5Mo, ZG15Cr1MoV, ZG20CrMoV, WC6, WC9, C12A, وغیرہ. can work normally in high temperature environments of 550°C to 750°C. This type of material is indispensable in high temperature conditions such as thermal power generation and petrochemicals due to its excellent high temperature strength and oxidation resistance.
