Passive Fire Protection

Passive Fire Protection

Passive fire protection (PFP) coatings are increasingly important in the oil and gas industries. Applied to industrial oil and gas installations, the coatings expand to form an insulating layer of carbon char when exposed to high temperatures.

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.
