ASTM A105 Carbon Steel Plate Flange
ASTM A105 carbon steel forged large butt welding flange, the corresponding American standard production standard is ASME B16.47, which is divided into A series flanges and B series flanges.
1. Size range: Mainly suitable for large flanges from 26 inches to 60 inches.
2. Pressure range: A series: Class 150, 300, 400, 600, 900 and other 5 levels; B series: Class 75, 150, 300, 400, 600, 900 and other 6 levels.
3. Flange type: 2 types of flange: butt welding flange (WN FLANGE) and blind plate (BL FALNGE).
4. The difference between A series flanges and B series flanges: A series specifies the flange dimensions of general flanges, and B series specifies the flange dimensions of compact flanges. The bolt hole diameter of A series flange is larger than that of B series flange, and the number of bolt holes is smaller than that of B series flange. B series flanges have smaller bolt holes than A series flanges, and have more bolt holes than A series flanges.
