Understanding Overpressure and Thermal Relief

Thermal relief refers to automatic release of fluids or gases from a system to a specified level. Pressure relief systems are intended to prevent pressures in process equipment from increasing to the point where a mechanical failure or rupture might take place, automatically releasing any materials within.

Firefighting Foam Demand Calculations

Firefighting Foam has been widely used as a fire extinguisher for flammable and combustible liquids for many years. It is consisted of premix solution (a ratio of water and foam concentrate) mixed with air. It forms a stable form blanket which spreads above the fuels and adheres to surfaces.

Foam forms a film above the fuel surface and seals vapor. Fire fighting foam concentrate prevents fuel contact with oxygen, resulting in fire suppression. It also has a high cooling effect and will avoid reignition. Read More
