Calculation Formula of flange bore B
For Serise A CLASS 150∼300 and Serise B CLASS 400∼900
BORE B=DIAMETER OF HUB AT BEVEL H−2×WALL THICKNESS t
Note:Diameter of Hub at Bevel H is equal to Outside Diameter of Pipe.
For Serise B CLASS 75∼300
BORE B=OUTSIDE DIAMETER OF PIPE−2×WALL THICKNESS t
Note:Diameter of Hub at Bevel H is different from Outside Diameter of Pipe.

Notes:
①The tolerances for f, g and h shall be appropriately determined for individual cases in such a way as well cause no inconveniences in practice.
②As to the outside diameter(d)of the pipe to be jointed, those shown in the table or other sizes nearly equal to them shall be used.
③The joint face of the flange can be made as shown by the broken line.
④The bolt fastening face of the flange shall be finished in parallel to the joint face of the flange.
⑤In case O ring is used for the gasket, the chamfered edge of the groove can be made smaller than shown above.
