Types of Flame Arrestor

Flashback arrestors are safety devices designed to prevent the reverse flow of gas in an oxy-fuel system.

A flashback occurs when the flame propagates back into the fuel or oxygen hoses, which can lead to an

explosion. Flashback arrestors work by quenching the flame with a wet or dry barrier, depending on the

type of arrester used. 


Normally, We Classify flame arresters into two types

There are two main types of flashback arrestors:

1.  Dry flashback arrestors: 

 These arrestors use a porous sintered element to extinguish the flame. The sintered element is typically made

of metal or ceramic and has a very small pore size. When a flashback occurs, the flame is forced through the

sintered element, which breaks up the flame and extinguishes it.

2. Liquid flashback arrestors: 

These arrestors use a non-flammable liquid to extinguish the flame. The liquid is typically water or a water-based

solution. The gas is bubbled through the liquid, which cools the flame and extinguishes it. 


Liquid flashback arrester


Dry flashback arrestors are more common than liquid flashback arrestors because they are less likely to freeze

or become contaminated. However, liquid flashback arrestors are more effective at extinguishing large flashbacks. 


If classified by gas, there are the following types

Gas TypeFlashback Arrester Type
Oxygen Dry flashback arrester
Fuel Dry or liquid flashback arrester
Mixed Dry flashback arrester



Choosing the Right Flashback Arrester

The type of flashback arrester that is used depends on the specific application. For example, dry flashback

arrestors are typically used for oxy-fuel welding and cutting, while liquid flashback arrestors are typically used for

oxy-fuel brazing and soldering.


It is important to consult with a qualified professional to choose the right flashback arrester for your application.

Where to install flashback arrestors

Flashback arrestors should be installed as close to the potential flashback source as possible.

This means that they should be installed on both the oxygen and fuel hoses, as close to the torch

as possible. In some cases, it may also be necessary to install flashback arrestors on the regulators.

Here are some specific guidelines for where to install flashback arrestors:

* On the oxygen hose: Install the flashback arrester on the oxygen hose between the regulator and the torch.
* On the fuel hose: Install the flashback arrester on the fuel hose between the regulator and the torch.
* On the regulators: In some cases, it may also be necessary to install flashback arrestors on the regulators.
This is especially true if the regulators are not equipped with built-in flashback arrestors.
