ASME B16.47
ASME B16.47 is an American National Standard that specifies the dimensions, tolerances, materials, testing, and marking requirements for large-diameter steel flanges used in piping systems. It covers flanges with nominal pipe sizes from 26 inches to 60 inches, ensuring compatibility and safety in industrial applications such as oil and gas, chemical processing, and power generation. The standard is divided into two series: Series A (equivalent to MSS SP-44) and Series B (equivalent to API 605), each with different pressure ratings and dimensions.
Developers and engineers should learn ASME B16.47 when designing or maintaining large-scale piping systems that require flanges for connections, as it ensures compliance with safety and interoperability standards in high-pressure environments. It is essential for projects in industries like petrochemicals, where flanges must withstand extreme conditions and meet regulatory requirements, reducing the risk of failures and ensuring reliable operation.
