Brass compression fittings onto steel pipe. District heating

[Mike2007]

Will brass compression fitting (olive and nut) go onto existing steel pipework (35mm) . Wanting to create a branch for supply to a flat heating circuit.
I have used press fit before but there are only four join points to give a branch of 28mm copper F&R.

No.

You'll need something like a Primofit coupling.

nope and if it really is a district heating system you shouldnt be touching it, they can work at really high pressures

And/or steam.

Believe it or not this system isn't pressurised or sealed!
The pipework hasn't been fully inspected (due to insulation) and could be copper pipe. I have built large diameter pipework before with geberit pipe.
