Evaluating High-Temperature Intumescent Insulation Materials Under Fire and Blast Conditions


This paper describes recent testing conducted to evaluate the performance of high-temperature intumescent materials under adverse fire and blast conditions. Results from fire performance evaluations currently protecting offshore oil platforms are presented. Extensive fire and blast qualification testing of epoxy-based intumescent materials has been conducted utilizing specially designed blast chambers, jet fire facilities, and laboratory furnaces. Blast chambers are capable of loading up to a 3 × 3-m insulated bulkhead assembly to a 2 bar over pressure and having a duration of approximately 250 millisecond generated by a controlled flammable vapor cloud explosion. The jet fire test exposes an insulated test specimen to a fire environment characterized by temperatures of approximately 1100°C, sonic gas velocities, and peak heat flux levels in excess of 300 kW/m2.
