* For flanges type 21 the outside hub diameter approximately corresponds to the outside pipe diameter.
Note : The p/t rating from EN 1092-1 apply only for flange type 05, 11, 12, 13 and 21 having nominal sizes up to and including DN 600. The p/t rating of all other flanges shall be agreed between the manufacturer and the purchaser. |
