ASTM A694 is a standard specification for carbon and alloy steel forgings for pipe flanges, fittings, valves, and other parts for high-pressure transmission service. This specification covers several grades of low-carbon and alloy steel forgings, which are intended for use in high-pressure and high-temperature service conditions.
ASTM A694 flanges are typically used in applications such as petrochemical plants, power generation, and oil and gas pipelines, where high-pressure and high-temperature conditions are present. These flanges are available in various sizes, materials, and pressure ratings to meet the specific requirements of different applications. The flanges are designed to provide a tight seal and prevent leakage in piping systems.
The ASTM A694 specification covers several grades of carbon and alloy steel forgings, including F42, F46, F52, F60, F65, and F70. Each of these grades has specific mechanical and chemical properties that make them suitable for different applications.

ASTM A694 is a standard specification for carbon and alloy steel forgings for pipe flanges, fittings, valves, and parts for high-pressure transmission service. It covers several grades of carbon and alloy steel forgings such as F42, F46, F48, F50, F52, F56, F60, F65, F70, F80, and F100.
The standard covers flanges in sizes ranging from 1/2" to 24" and pressure ratings of 150, 300, 400, 600, 900, 1500, and 2500. The standard also provides guidelines for marking, certification, and testing of the flanges.
Some key specifications of ASTM A694 flanges include:
Material: Carbon and Alloy Steel
Grades: F42, F46, F48, F50, F52, F56, F60, F65, F70, F80, and F100
Sizes: 1/2" to 24"
Pressure Ratings: 150, 300, 400, 600, 900, 1500, and 2500
Flange Face Types: Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ)
Flange Facing Finish: Spiral Serrated, Concentric Serrated, Smooth, and Phonographic
Manufacturing: Forged
Testing: Hydrostatic, Ultrasonic, and Magnetic Particle
Marking: Grade, Size, Pressure Rating, Manufacturer's Name or Symbol, Heat Number, and Country of Origin.
It's important to note that ASTM A694 flanges are not suitable for low-temperature service. For such applications, other standards like ASTM A350 and ASTM A333 should be used.
