Steve With my previous-previous employer, I remember we had serious issues with local made cast iron fittings in China, say 2002 - 2005 era. OS&Y valves corroded, internal stem u/g valves seized in 12 months or so, fittings showed accelerated corrosion. Memory says we then gave it to workmanship, quality control and materials in general.

I have a project that has multiple instances of severe exterior corrosion on Chinese 1" threaded 90's and the adjacent piping. I heard of the same issue with from a colleague last week - also with Chinese cast fittings from 2001-2002. We had sections removed and tested but could not find the problem Has anyone else come across this? Thanks very much, Steve Kowkabany, P.E.
