    Hello! It is possible, you can use the PND corrugation yet. You can sewer, the purpose of the pipe is to protect the cable from damage as a result of settling of the wall or grinding.
    I will repeat your SNIP item:
    Building Norms and Rules SNiP 3.05.06-85 "Electrical Devices"
    paragraph 3.18.
    “The passages of unarmoured cables, sheathed and unprotected wires through fireproof walls (partitions) and interfloor ceilings must be made in pipe sections, or in ducts, or openings, and through combustible - in segments steel pipes. "
    Those. not regulated material for fireproof walls.
