ASME B16.47 flanges are large diameter flanges designed to meet the ASME B16.47 standard, which governs the dimensions, materials, pressure ratings, and types of flanges used in piping systems. This standard is essential for applications that require high-pressure, large-diameter flanged connections, typically found in industries such as oil and gas, petrochemical, and power generation. These flanges are capable of withstanding extreme pressures and temperatures, making them suitable for heavy-duty, industrial pipeline systems.
