ASTM A694 F60 Blind Flange for Sealing Pipes and Valves in High-Pressure Environments
SA 694 flange is used to connect pipes, valves, pumps and other equipment to form a pipeline system. Usually welded or threaded connections are used. Its joint is formed by bolting two flanges together with a gasket between them to provide a seal.
ASTM A694 flanges are available in different types such as ASTM A694 sliding flange, ASTM A694 blind flange, ASTM A694 socket weld flange, ASTM A694 orifice plate flange, ASTM A694 long weld neck flange, ASTM A694 threaded flange wait.
A694 steel flange grades range from ASTM A694 F42 to ASTM A694 F70.
ASTM A694 material is carbon steel and alloy steel flanges used for
high-pressure liquid transportation. Its material grades include
F42, F46, F50, F52, F56, F60, F65 and F70.
Flanges, fittings, valves, and other components in the A694 specification are suitable for high-pressure transmission applications. Therefore, carbon steel ASTM A694 F70 flanges are widely used in petrochemical, oil and gas, and nuclear power industry applications. Different types of flanges are used for different connection types.
