Two distinct types of passive fire protection products are normally used in hydrocarbon-processing complexes:
- Cementitious products are generally based on Portland cement plus lightweight aggregates. Cementitious materials protect the steel in two ways. Firstly, they contain trapped moisture, which in a fire situation will boil and keep the steel temperature around 100 °C until all the water has disappeared. Secondly, the high mass and low thermal conductivity of concrete make it very effective at reducing heat input to the underlying structure.
- Intumescent coatings are generally epoxy based, spray or hand applied. Intumescent coating, when exposed to sufficient heat, will expand to form a thick, insulating carbonaceous char.
We offer a wide range of Passive Fire Protection and all our applicators are qualified and approved for Pitt-Chat Range, Full Chartek Range and Leighs M90 range.
