Corrosion protected pipe

[Albumen]

A gas fitter has replaced a length of gas pipe, inside the house. It runs down the corner of a room. After a conversation with the plasterers I thought they were going to leave it to be boxed in.

But they've plastered it in. Or rather trapped it behind the dry lining. Before they plastered it in all I could see was plain copper pipe. The ends are just accessible and I can't see any tape.

As far as I can tell it should be protected from corrosion. Am I correct?

I'm going to ask the builder to replace it. I want it surface mounted. I don't mind it being exposed, or boxed in for aesthetics.

Some copper gas pipe is apparently corrosion protected already. In case the fitter says that's what he fitted, is there an easy way to tell what corrosion fitted pipe looks like. As I said I can just see the top of the new pipe.

Many thanks.
