More Information For A105 B16.5 Flange
SSM supplies A105 ASME B16.5 flanges, which can be selected according to your requirements based on the following classifications and applications:
Classification by Connection Type
- ASME B16.5 A105 Slip-on Flange: The flange is slid onto the pipe and welded.
- ASME B16.5 A105 Welding Neck Flange: A flange with a neck, welded to the pipe.
- ASME B16.5 A105 Blind Flange: A flange with no hole, used to seal the end of a pipe.
- ASME B16.5 A105 Threaded Flange: Flanged with threads to connect to the pipe.
- ASME B16.5 A105 Socket Weld Flange: Suitable for small diameter pipes, welded to the pipe through a socket.
- ASME B16.5 A105 Lap Joint Flange: A flange welded to the pipe, often used with a loose flange.
Classification by Seal Face Type
- ASME B16.5 A105 Flat Face Flange: The seal face is flat.
- ASME B16.5 A105 Raised Face Flange: The seal face is raised.
- ASME B16.5 A105 Ring Joint Flange: Uses a metal ring as a sealing element.
- ASME B16.5 A105 Tongue and Groove Flange: One flange has a tongue, the other has a groove.
Classification by Pressure Rating
- ASME B16.5 A105 150#: Suitable for lower pressure pipe systems.
- ASME B16.5 A105 300#: Suitable for medium pressure pipe systems.
- ASME B16.5 A105 600#: Suitable for high pressure pipe systems.
- ASME B16.5 A105 900#: Suitable for higher pressure pipe systems.
- ASME B16.5 A105 1500#: Suitable for very high pressure pipe systems.
