Flame arresters are specialised mechanical devices designed to permit the flow of air or fluid while preventing the progression of a flame. They are strategically installed to halt the movement of flames through pipelines (in-line) and into containers (end-of-line). Their operation hinges on two key principles: firstly, they eliminate the oxygen within a flame, effectively extinguishing it, and secondly, they reduce the flame’s temperature below its auto-ignition point. Flame arresters are indispensable in environments where flammable liquids and gases are prevalent. This includes but is not limited to, fuel terminals, chemical plants, distilleries, and pharmaceutical plants.
Flame arresters play a crucial role in limiting the damage caused by ignition. They can inhibit a fire from spreading from one area of a facility to another and prevent a flame from penetrating a vessel and igniting vapour. These devices are designed to curb flame propagation in gas piping systems and safeguard low-pressure tanks containing flammable liquids. By protecting low flash point liquids from external heat and ignition sources, flame arresters enhance fire protection and safety.
Types of Flame Arresters we Supply
- Deflagration Flame Arresters: Deflagration describes a subsonic combustion process that propagates through heat transfer, where hot burning material heats the next layer of cold material and ignites it. This type of combustion is commonly observed in everyday fires and explosions.
- Detonation Flame Arresters: Detonation, on the other hand, is a supersonic combustion process that propagates through shock. It involves a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations are typically observed in conventional solid and liquid explosives, as well as in reactive gases. Gaseous detonations usually occur in confined systems but can occasionally be observed in large vapour clouds. They are often associated with a gaseous mixture of fuel and oxidant of a composition slightly below conventional flammability limits.

End-of-Line vs. In-Line Flame Arresters
The difference between End-of-Line and In-Line Flame Arrester products is defined by ISO 16852.
End-of-Line Flame Arrester (ISO 16852 section 3.21): This type of flame arrester is fitted with one pipe connection only. Eccentric
In-Line Flame Arrester (ISO 16852 section 3.22): This type of flame arrester is fitted with two pipe connections, one on each side of the flame arrester. Concentric
