German Pipe Fittings
On my trip back from Stockholm, between Osnabruck and Cologne, I sat next to a German electrical engineer.
He astounded me at one point, by saying that German pipe fittings on industrial plants were in Imperial units.
I have been unable to check on the Internet, but I assume it is true and is probably down to American influence.

Sorry James BSP ( British Standard Pipe ) is a British standard accepted by the World in Victorian times and had nothing to do with the Americans but good old British Engineering that used to lead the World.

It seems to still be better than Italian engineering.

All pipe fitting threads (not bores) are in imperial units (BSP or British Standard Pipe) sizes.

I recall the story of Eng. Dept at Welwyn carefully constructing a plant on the Continent using metric fittings, only to hear from the Continental customers later that they had got the fittings all wrong………….they should have used Imperial, which they used as their own standard!
