I found this site and its verry usefull to me so maby it will help others.
http://www.gizmology.net/pipe.htm
The page has Copper, PVC, Wrought Iron, and Cast Iron Pipe info.

p.s. sorry mods if i put this topic in the wrong section i didnt know where info like this should go so i just thought that this would be a good place.

I don't like that site, it has some things which aren't true, it says abs is brittle.
And some of the pressure ratings on the pcv seem wrong to me.
