DN 165

[Kalsto]

Anyone come across DN165 flanges before?
It measured up as a 6” flange. I’ve never come across this myself. DN150 and DN175 yes. See picture.

Definetly a bit odd alright. Not many even have 175, never mind 165.

It's as though someone has mis thought 6", which is actually 6.5" OD (165mm) pipe size.

I can't find anything which supports this, but type 12 is a slip on flange so maybe they stamped it that way to say it fits a 165mm OD pipe?

Are there any other numbers around the flange?
