• DIN 4804 - Is the equivalent to ASME B1.201 pipe thread and ASME B16.5 for flanges.


• DIN 17175 - Meets the ASME/ASTM tubing specifications for SA-192, SA 210 A1, SA-209 T1 and a number of other ASME standards. The equivalent is also the British standard 3059 S1 440, 3059 S1 360 and 305 S1 243.
