ASME B16. 47: This standard covers large diameter steel flanges, typically used in high-pressure applications where larger bore sizes are needed.

Big diameter flanges, also known as large diameter flanges, play a crucial role in various industrial applications where substantial piping systems are employed. These flanges are designed to connect large pipes or vessels, providing a secure and sealed connection. The term "big diameter" typically refers to flanges with sizes ranging from several inches to several feet in diameter, and they are commonly used in industries such as oil and gas, petrochemicals, power generation, and water treatment.
