Is it OK to bury copper pipe in concrete?

The copper tube must be completely embedded in the concrete and adequate provision for thermal expansion should be provided where the tube enters/exits the concrete.

What does sleeving pipework prevent?

In a fire situation the sleeve expands to fill the available space between the pipe and the penetration. In the case of plastic pipes the sleeve will crush and close off the pipe forming a solid char and preventing the passage of fire and smoke to the adajcent compartment.

What is the purpose of a sleeve in a concrete wall?

Acts as toe guard. For wall penetrations it can be a type of strengthening. Together with packing it helps to protect from fire spread from one room to other.
