How to Choose the Right Flame Arrester for Your Application

Flame Arrester

Understanding Flame Arresters

The risk of fire and explosion is a crucial element of industrial environment safety that cannot be ignored. Flame arresters play a crucial role in mitigating these risks by preventing flames from spreading to potentially hazardous areas. However, choosing the right flame arrester for your specific application requires careful consideration and understanding of various factors. 

What is a Flame Arrester?

A flame arrester is a safety device designed to stop the propagation of flames by allowing gases to pass through while extinguishing the flame. It consists of a mesh or perforated metal element that cools down the flame below its ignition temperature, preventing it from reaching the flammable mixture.

How Do Flame Arresters Work?

Flame arresters work based on the principle of heat dissipation.The metal surfaces of the arrester absorb and release heat as a flame travels across them, putting out the flame. Simultaneously, the device prevents flame flashback and the transmission of flame into the protected equipment.

Factors to Consider When Choosing a Flame Arrester

1)Identify the Application Requirements

The first step in selecting the right flame arrester is to understand your specific application requirements. Think about elements including the system’s flow rate, temperature, and pressure conditions, as well as the kind of combustible substance being used.

2)Determine the Correct Type of Flame Arrester

Flame arresters come in a variety of forms, such as detonation and conflagration arresters. Deflagration arresters are suitable for low-pressure applications, whereas detonation arresters are more appropriate for high-pressure scenarios. Ensure you choose the correct type that matches your application.

Check for Compliance and Certifications

Before making a final decision, ensure that the flame arrester you intend to purchase complies with relevant industry standards and safety regulations. Look for certifications such as ATEX, FM, or IECEx, as they indicate the device’s reliability and performance.

Consider the Material of Construction

The material of construction is crucial, especially when dealing with corrosive or aggressive substances. Stainless steel flame arresters are commonly used for their durability and resistance to various chemicals.

Evaluate Maintenance Requirements

Efficient maintenance is vital to ensure the flame arrester continues to function optimally. Consider the ease of inspection, cleaning, and servicing when choosing a flame arrester.

Selecting the Right Flame Arrester for Specific Applications

1)Flame Arrester for Storage Tanks

When selecting a flame arrester for storage tanks, consider the tank’s contents and the possibility of vapor formation. Ensure that the arrester can handle the tank’s vapor pressure and flow rates.

2)Flame Arrester for Gas Pipelines

For gas pipelines, opt for flame arresters that can handle high-pressure applications. Detonation arresters are often the preferred choice due to the potential for shock waves.

3)Flame Arrester for Vent Stacks

Vent stacks require special consideration, as they must prevent flame propagation during normal operations while still allowing sufficient venting. Choose arresters with low-pressure drop to maintain system efficiency.

4)Flame Arrester for Industrial Processes

In industrial processes, where flammable gases are present, deflagration arresters are commonly used. Ensure that the arrester is resistant to the process environment and can handle the required flow rates.


Selecting the right flame arrester is vital to ensure the safety of industrial processes involving flammable substances. By understanding your application requirements, identifying the correct type of arrester, checking for compliance and certifications, considering the material of construction, and evaluating maintenance needs, you can make an informed decision.
