ASTM A694 refers to the material of carbon and alloy steel pipe flanges, fittings, valves and parts for high pressure liquid transmissions. It covers material grades of F42, F46, F50, F52, F56, F60, F65 and F70.
ASTM A694 Flange comes in different grades such as F42, F52, F60, F65 and F70. The difference is in the chemical composition. The ASME SA694 High Yield CS F52 Slip On Flangehas carbon, silicon, manganese, phosphorus, sulfur, molybdenum, nickel, chromium, copper, vanadium and niobium in the composition. ASTM A694 Flange
ASTM A694 F65 CS Flanges Specification . Material : ASTM A694 F65 CL1/CL2 Size Range: 1/2″ (15 NB) to 48″ (1200NB), ASME B16.47 Flanges size range: 26″ to 60″; Typical manufacturing specifications: A694 F65 , ASME A694 F65, MSS SP 44, ASME B16.47, ASME B16.5, NORSOK L-005, API 6A
The pressure classes of the ASME SA 694 F65 Flange range from #150 through #2500 and the pressure numbers range from PN6 through PN64. There are plain and A694 F60 Threaded Flange types. The face type varies as flat face, raised face and ring type joint. Depending on the flange flare, there are raised flanges for better connection services.
ASTM A694 F65 Flange Physical Properties The ASTM A694 F65 forgings can be furnished in carbon steel, low alloy steel or alloy steel. The steel shall be made by either open hearth, electric furnace, or basic oxygen process and it shall be fully deoxidized.
