Application Summary AI generated
This standard specifies the dimensions, materials, and performance requirements for Class-designated fasteners (bolts, studs, and nuts) used in steel pipe flange joints. It is applied in industrial fluid systems, such as oil and gas, chemical, and power generation pipelines, where flanges are joined under specific pressure-temperature ratings. The standard ensures compatibility and sealing integrity in Class-rated flanged connections, particularly in high-pressure or high-temperature environments.
