Abstract
A series of experimental studies to determine the fire protection efficiency of two-component epoxy thermally expanding coating for steel structures when exposed to hydrocarbon temperature regime has been carried out. The calculated thermo-physical characteristics of the flame retardant coating have been obtained. Based on calculation results there are constructed nomograms of heating of steel structures with the reduced thickness of metal from 2 to 20 mm and the thickness of epoxy coating from 1 to 9 mm. The obtained nomograms combined with the calculated value of the critical temperature allow to assess the fire resistance of steel structures of any configuration with different thicknesses of epoxy coating.
