3. Forged Weld Neck Flange Selection Recommendations
Material Selection Based on Medium Characteristics:
For weakly corrosive media, carbon steel or stainless steel (e.g., F304) can be used.
Material Selection Based on Medium Characteristics:
For weakly corrosive media, carbon steel or stainless steel (e.g., F304) can be used.
For strongly corrosive media (e.g., acids, alkalis, seawater), stainless steel (e.g., F316) or special alloys (e.g., Hastelloy) are recommended.
For high-temperature, high-pressure corrosive media, alloy steel (e.g., F11, F22) can be selected.
Consider Environmental Factors:
In chloride-containing environments, prioritize materials with chloride ion corrosion resistance (e.g., F316, duplex stainless steel).
In high-temperature environments, choose materials with high-temperature oxidation resistance (e.g., F321, F22).
The selection of the Forged Weld Neck Flange should be based on specific working conditions and medium characteristics to ensure stable operation in different environments.
