It is therefore sufficient to stamp the nominal diameter (DN) for marking purposes. In contrast to the DIN standard, EN-1092-1 only specifies the pipe connection dimensions of the ISO series. The European standard EN 1092-1/01 has replaced the national standard DIN 2576 in 2007. New in EN 1092-1 are the pressure levels PN 16 and PN 40 for plate flanges. to EN 1092-1 type 01įor nominal sizes larger than DN 150, EN standardizes pressure levels PN 10 and PN 16.įrom DN 50 to DN 150, the EN refers to the standard series of PN 16 pressure level.įor dimensions up to DN 40, the EN refers to the standard series of PN 40 pressure level. The p/t rating of all other flanges shall be agreed between the manufacturer and the purchaser. 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. * For flanges type 21 the outside hub diameter approximately corresponds to the outside pipe diameter.
