Flanges are made from normalized forgings and are usually of two kinds of material, steel ST52.3 and stainless steel AISI SS316L.
SAE Flanges come in two series, SAE code 61 (3000 series) and SAE code 62 (6000 series). For code 61 (3000# series), they are available in all nominal sizes between DN10 (3/8″) and DN125 (5″). For code 62 (6000# series), they are available in all nominal sizes between DN10 (3/8″) and DN80 (3″)
The standard pressure ranges from 34 to 345 bar for code 61 (3000 series) and 200 to 414 bar for code 62 (6000 series). Please take note that the pressure information of the flange and connected equipment combinations may vary from each other. For example: if a pipe connected to the flange has a lower working pressure, it will result in an overall lower working pressure of the system. Therefore, please consider the lowest pressure as the maximum working pressure of this combination.
The standard working pressure of carbon steel SAE flanges is between -40°C and +120°C. For stainless steel, the standard working pressure is between -60°C and +50°C. Working Pressure for SAE Flanges made from stainless steel and used at elevated temperatures have to be:
