Fire Performance

Fire Performance

• 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 periods of up to 4 hours
• The required wall thickness of Fire Tube to provide a particular fire resistance for a specified period depends on the diameter, wall thickness and critical (fail) temperature of the steel column or pipe. However, in the case of pipes, the critical temperature is likely to depend on its contents

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
• Where thk = wall thickness in m

Please see the FIREPRO Book in the 'Data Sheets' tab for detailed information including critical steel temperatures etc.

Standards and Approvals

• Fire Tube conforms to BS 3958: Part 4, ‘Bonded preformed mineral wool pipe sections’
• Full-scale independent test data has been verified and assessed by BRE Global in Fire report number: CC 276856A
• This product has been authorised for use in LUL surface and sub-surface premises when installed in accordance with this
  datasheet - please refer to the LUL Approved Product Register website www.LU-apr.co.uk for specific details

Application Notes

• Fire Tube is light and easy to cut to shape using a saw or a sharp knife
• Abutted sectional joints/ tube ends of the Fire Tube (including the partially split ‘hinge’ and the tube ends) are to be applied with Rockwool Firepro Glue prior to application
• All joints should be held firmly together with temporary bands of steel wire, jubilee clips or plastic cable ties at 200mm centres until adhesive within joints and between Tube ends has fully cured
• If installed outdoors, Fire Tube must be protected from the weather
• Prior to use, Fire Tube should be stored indoors or protected by a weather proof covering

Please see the FIREPRO Book in the 'Data Sheets' tab for detailed information.
