National legislation and international standards, as well as company defined risk acceptance criteria, impose certain requirements on the design of process facilities regarding their ability to sustain a fire situation. We have developed tools and work methods to address these issues, and we have a long list of reference projects.
Fire integrity of pipe-work and equipment under pressure is a function of fluid characteristics, process conditions, materials, the presence of passive fire protection, blowdown and depressurization facilities. When e.g. a hydrocarbon fluid is heated, components will boil off in accordance with its thermodynamic properties, and the pressure inside the pipe-work/vessel will increase. The increased pressure will impose a higher load on the process equipment. As the material in pipe-work and vessels is heated, the material starts to lose its strength.
