Fire Tube Certification Full-scale independent test data has been verified and assessed by BRE Global in Fire report number: CC 276856A. The fire performance of Fire Tube has been reviewed by the Fire Test Study Group for inclusion in the ASFP Yellow Book, endorsed by the Steel Construction Institute. British standards Fire Tube conforms to BS 3958: Part 4, ‘Bonded preformed mineral wool pipe sections’. Performance data Fire report CC 276856A details the expected fire resistance performance relating to critical steel temperatures of 50, 100, 150, 200, 250, 300, 350, 400 and 550°C for...

Fire Tube Structural steel fire protection The section factors A/V (Hp/A) for standard structural steel sections can be found in the ASFP Yellow Book or can be calculated for each element by dividing the perimeter (circumference) exposed to fire (A) by the cross sectional area (V). For circular sections (including pipes), the following, simplified formulae can be used to calculate the A/V section factors:Solid sections: A/V = 4 / OD Hollow sections: A/V = OD / (thk (OD - thk)) Where OD = outside diameter in m and thk = wall thickness in m Fire Tube wall Maximum A/V section factors for 550°C...
