2024-02-29 ASME B16.5 is a standard developed by the American Society of Mechanical Engineers (ASME), which specifies in detail the dimensions, tolerances, markings, materials, and other related requirements for pipeline flanges and flange connections. Carbon steel flange refers to a flange forged from carbon steel material. ASME B16.5 carbon steel flanges typically refer to flanges that comply with ASME B16.5 standards and are manufactured using carbon steel materials. Carbon steel is a commonly used metal material with good strength, plasticity, and weld ability, therefore it has been widely used in industrial manufacturing. This type of flange can be used in various pipeline systems, especially in environments that require high pressure and temperature resistance.
