You CAN get steel thin wall central Vacuum pipe and fittings.
They should hold up to the concrete pour, but I won't swear to it.
The biggest problem I see it sealing the end at the wall, and being able to open it back up after the pour to put the inlet valve on.
Plus you could well have an issue with the needed low voltage wiring.
How's your welding talents?
