In this section of the CINI Manual, fireproofing of piping and equipment in combination with insulation materials only will be described. These systems shall comply with the same applicable codes and standards as for fireproofed structures in the same plant.

In general, fire proofing systems are usually applied as a protection of steel structures/supports, piping, valves or equipment of process plants against thermal load, caused by a (hydrocarbon) fire. Such fire proofing systems are to provide protection for a limited period of time, by preventing temperature rise above the critical (steel) temperature and/or the critical temperature of the product inside.
