Passive fire protection systems for conduit, cable trays, support rods, and structural steel

摘要

A passive fire protection system for the protection of conduits, cable trays, support rods, and structural steel against flame and heat in a severe total environment type fire such as a hydrocarbon fire which includes a multi-layered (laminated), flexible material containing a plurality of layers of intumescent materials. This multi- layered material is configured such that it provides a containment system for the carbonaceous foam resulting from the expansion of the intumescent materials.
