Applications of Flanges
Flanges are widely used in industrial, municipal, and energy sectors, serving as critical components for reliable piping, valve, and equipment connections. Below are their key application scenarios:

Oil & Gas Industry
Common Types: Weld Neck (WN), Ring-Type Joint (RTJ)

Chemical & Pharmaceutical Industry
Common Types: Slip-On (SO), DIN 11851 (Hygienic)

Power & Energy
Common Types: Spectacle Blind, Lap Joint

Municipal & Construction
Common Types: Blind Flange, Threaded

Marine & Offshore Engineering
Common Types: Orifice Flange, Swivel Ring

Special Industrial Applications
Key Selection Criteria
1.Medium Properties: Corrosiveness, temperature, pressure (e.g., PTFE-lined for acids).
2.Connection Type: Welded, threaded, or bolted (e.g., WN for high pressure).
3.Standards Compliance: GB (China), ANSI (USA), EN (EU), JIS (Japan).
Conclusion
Flanges are indispensable across industries—from water supply to nuclear plants. Proper selection enhances system safety, maintenance efficiency, and longevity.
