Fire safety in the chemical, petrochemical and gas industry: Flame and Detonation Arresters

Because it is extremely important to limit fire hazards in the chemical, petrochemical and gas industry, we would like to explain more about flame and detonation arresters.

Flame and detonation arresters by Groth Corporation inhibit flame propagation in gas piping systems and protects low pressure tanks containing flammable liquids. 

  • Use flame arresters to protect low flash-point liquids from external sources of ignition and increase fire protection and safety.
  • The design of the flame arrestor makes it ideal to protect liquid storage tanks containing both NEC Group D and Group C vapors (IEC Class IIA and IIB1 through IIB3 vapors).
  • Protect liquid storage tanks containing NECC Group D (IEC Class IIA) gases with Maximum Experimental Safe Gap (MESG) equal to or greater than 0.90 mm.
  • Quick and easy cleaning and maintenance.


Flame arresters protect storage tanks containing flammable liquids: they prevent flame propagation to the tank from the exterior, through the piping.  In the piping: gas (ex: vapors of the liquid in the tank).

So this is for all industries storing flammable liquids (refineries, tank storage, chemical and petrochemical industries).
