Evaluating high-temperature intumescent insulation materials under fire and blast conditions
- Hughes Associates, Inc., Baltimore, MD (United States)
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 x 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/m{sup 2}.
