Installation of CS valve on CI pipe line by using Adapter Flnage

[engrasad364]

Hi: I've got an unusual application (for me, anyway) which requires an adapter to take me from Csat Iron pipe 8", Line is Underground Oily Water seawer (OWS)
I need to install 8" Isolation valve in this line, as it is difficult to weld on Cast Iron pipe so I am thinking about to put Adapter flange in between and then install 8" CS valve.
plesae give your expert opinion if yoiu feel any thing wrong while doing this.

Adaptor flange between what exactly. Some engineering details or a drawing would help a lot here.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

More info would probably help ("cast iron pipe" alone is a very broad subject, FYI
