ASTM A105 Flange is an integral component made from forged carbon steel designated for use in pressure systems and can handle both ambient and higher-temperature services. The chemical composition of these flanges—highlighting a max of 0.35% carbon and a manganese range of 0.60-1.05%, with minimal phosphorus and sulfur ensures resilience and longevity. These carbon steel flanges are designed to provide reliable sealing and strength in various applications.
ASTM A105N Flanges come in different pressure ratings, serving classes starting from 150 up to 2500, where they define their maximum allowable pressure. Its pressure can reach 1,200 PSIG at 500 °F, which makes it high-pressure application-friendly. However, the rating varies with design pressure and temperature. For instance, the class 150 A105 flange can handle different pressures due to the temperature. Up to 270 pounds per square inch (PSI) (1861 KPA) of pressure can be withstood by it at room temperature. With increasing temperature, its pressure handling capability reduces. So, at about 400ºF (204ºC) it can handle 180 PSI (1241 KPA); at around 600ºF it can handle 150 PSI (1034 KPA); and at approximately 800ºF it can handle 108 PSI.
