German term or phrase: DN 100

The context is a discussion of pipe systems. The sentence is "...30 Tonnen Granulat können in einer Rohrnennweite DN 100 wirtschaftlich gefördert werden." My questions are as follows: what does DN stand for (this is not a typo for DIN or DNC) and why did the translator who worked on this before me translate it as "ND 100"? Thanks in advance.

English translation:DN = Nennweite

Explanation:
DN is an abbreviation used for 'Nennweite' in the DIN standards and in technical specifications usually making reference to the 'nominal size' or 'nominal diameter' of piping or fittings. You can find references to Nennweite under WWW.DIN.DE

nominal pressure

Explanation:
I believe that this is a typo and that "DN 100" should really be "ND 100". Richard Ernst's Wörterbuch der industriellen Technik states: ND (Rohrleitung) = Nenndruck; Nenndruck m / nominal pressure.
And in your context, this would make perfect sense.
Cheers,

nominal diameter

Explanation:
I found this awhile ago in a piping translation, but I did not note the source. ND 100 = nominal diameter of 100 mm

DN = Diamter nominal for piping

If you look for the combination DN + pipe you'll find a whole host of cases where this term is used.

Why ND

Explanation:
I forgot to add my two cents regarding the usage of ND. I can only assume that the other translator knew that abbreviation stands for 'nominal diameter' and thus decided to coin his/her own English abbreviation for it. As far as I am aware, the abbreviation is international considering I have seen it used in English specifications before.

nominal diameter

Explanation:
I'm terribly sorry about my earlier mistake. I did not see the word "Rohrnennweite" which of course already means "nominal pipe diameter".
