  • ASTM A105 (Carbon Steel)
Flange Type Common Materials Applied Components Function
Slip-On Flange Carbon Steel (A105), Alloy Steel (F11, F22), Stainless Steel (304, 316) Piping Connections, Heat Exchanger Shell Connects piping or equipment to the heat exchanger shell, easy to install and remove.
Weld Neck Flange Carbon Steel (A105), Alloy Steel (F11, F22), Stainless Steel (304, 316) High-Pressure Heat Exchanger Shell, Pipe Ends Provides high strength and stress resistance, suitable for high-pressure and high-temperature applications.
Threaded Flange Carbon Steel (A105), Stainless Steel (304, 316) Small Piping Connections Suitable for low-pressure systems or where welding is not required, allows quick connection and disconnection.
Socket Weld Flange Carbon Steel (A105), Stainless Steel (304, 316) Heat Exchanger Pipe Connections Used for small-diameter piping, offers good fatigue and leak resistance, suitable for high-pressure situations.
Lap Joint Flange Stainless Steel (304, 316), Alloy Steel (F11, F22) Piping, Heat Exchanger Shell and Heads Used with stub ends, allows flexibility for alignment and adjustment of connection parts.
Blind Flange Carbon Steel (A105), Stainless Steel (304, 316), Alloy Steel (F11, F22) Heat Exchanger Heads, Shell Ends Used to seal the openings of heat exchangers or piping, provides closure for maintenance and inspection.
Ring Type Joint Flange Alloy Steel (F11, F22), Stainless Steel (304, 316) High-Pressure Heat Exchanger Shell, Pipe Ends Suitable for high-pressure and high-temperature conditions, seals using a metal ring for better leakage resistance.

Sealing Face Types for Heat Exchanger Flanges

  • Raised Face (RF)

          Standard design for general applications.

        Contact pressure concentrated on the raised ring.

  • Ring Joint Face (RTJ)

          Uses metal ring gaskets for high-pressure systems.

        Ideal for critical sealing requirements.

  • Flat Face (FF)

        Full-surface contact with non-metallic gaskets.

        Suitable for low-pressure environments.
