A350 Grades LF1/2/3/6 – Low-temperature carbon steel (matching A333 pipe Grades 1 to 6).
ASTM A694 Grades F42 to F80 – High-yield carbon steel (matching API 5L pipe Grades X42 to X80).
ASTM A182 Grades F5 to F91 – Alloy steel flanges (matching A335 pipes P5 to P91).
A182 Grades F304/F316 – Stainless steel flanges (matching A312 SS pipes).
A182 Grades F44/F51/F53/F55 – Duplex and super duplex steels (matching A790/A928 pipes).
Nickel alloys – Includes Inconel, Incoloy, Hastelloy, and Monel.

Pressure Rating

ANSI flanges are available in multiple pressure ratings (e.g., 75#,150#, 300#, 400#,600#, 900#, 1500#, 2500#).

Flange Types

ANSI flanges include various types, such as:

Weld Neck Flange (WN)
Slip-On Flange (SO)
Blind Flange (BL)
Socket Weld Flange (SW)
Threaded Flange (TH)

ANSI/ASME B16.5 Flange

ASME B16.5 defines the flange dimensions, materials, pressure ratings, and other requirements for piping connections. It is published by the American Society of Mechanical Engineers (ASME) and is widely used in industries such as oil and gas, chemical, power, and water treatment.

ANSI B16.5 Class 150 Flanges

Working Pressure: Suitable for low-pressure environments, with a maximum working pressure of typically 150 psi.
Temperature Range: Suitable for applications at ambient temperature up to approximately 100°C (depending on material).
Applications: Widely used in water pipelines, light industries, and general chemical engineering.

ANSI B16.5 Class 300 Flanges

Working Pressure: Suitable for medium-pressure environments, with a maximum working pressure of about 300 psi.
Temperature Range: Suitable for applications at ambient temperature up to approximately 100°C (depending on material).
Applications: Mainly used in medium-pressure piping systems in industries such as chemicals, oil, and gas.

ANSI B16.5 Class 600 Flanges

Working Pressure: Suitable for higher pressure environments, with a maximum working pressure of typically 600 psi.
Temperature Range: Suitable for applications at ambient temperature up to over 100°C (depending on material).
Applications: Commonly used in high-pressure liquid or gas piping connections, such as in petroleum refining and natural gas processing.

ANSI B16.5 Class 900 Flanges

Working Pressure: Suitable for higher pressure environments, with a maximum working pressure of 900 psi.
Temperature Range: Suitable for high-temperature, high-pressure applications (depending on material).
Applications: Widely used in high-pressure piping systems, such as chemical reactors, oil drilling equipment, and industrial boilers.

ANSI B16.5 Class 1500 Flanges

Working Pressure: Suitable for high-pressure environments, with a maximum working pressure of 1500 psi.
Temperature Range: Suitable for extremely high-temperature and high-pressure working environments, typically used for high-temperature liquids or gases.
Applications: Primarily used in high-pressure oil, gas, and chemical systems, particularly in compressed gas and steam pipelines.

ANSI B16.5 Class 2500 Flanges

Working Pressure: Suitable for very high-pressure environments, with a maximum working pressure of 2500 psi.
Temperature Range: Suitable for extremely high temperatures and high pressures, capable of withstanding very harsh working conditions.
Applications: Widely used in extreme high-pressure environments, such as oil drilling, chemical processing, and steam boilers.
