ASTM A694-A694M is the standard specification for carbon steel and alloy steel forgings including pipe flanges, fittings, valves and other piping components for high-pressure transmission service. The material can be categorized into several grades: ASTM A 694 Grade F42, F52, F56, F60, F65 and F70. They are widely used in high-pressure oil and gas transmission pipelines as well as wellhead and manifold devices.
ASTM A694 forged flanges can be furnished in accordance with MSS SP 44, ASME B16.47(both Series A and Series B) and ASME B16.5.
Type of Flanges :
WN (Welding Neck), SO (slip on), PL (Plate), BL (Blind), Th (Threaded), SW (socket welding), LF/SE (lapped flange/stub end), LWN (long welding neck), Orifice flange, Reducing flange, etc
