DN dash size is response to Two lines of permissible pressures in bar for pipes , din 11850 reihe 1 and din 11850 reihe 2, Two temperature 20 and 150 C.

B.1 At a temperature of 20 C

DIN 11850 Tube dimension reihe 1 and rihe 2 At a temperature of 20 C

Pipes according to this standard can be used with static loads up to the pressures given in Table

The permissible pressures were calculated for welded pipes with the calculation value of the material number 1.4301 according to DIN EN 10088-2 - product form C (cold strip) taking into account a utilization of the permissible calculation stress of 100% in the weld seam.
