Sicherheitsaspekte bei Verwendung von Aluminium in Gas-Druckregel- und Messanlagen

A risk is given by aluminium in gas processing plants when in combination with rust an aluminothermic reaction can start.This strongly exothermic reaction leads to sparks with high energy content.The temperature reach values far about the ignition temperature of natural gas.A gas-phase explosion can be initiated by this ignition source.The occurrence of explosive mixtures in gas processing plants is possible during maintenance when gas pipes will be opened. A good protection against the aluminothermic reaction is to provide for avoidance of the material combination aluminium/rust in the plants.
