Selecting the Right Flame Arrestor: A Guide to Inline vs. End-of-Line Choices

Flame arrestors are essential safety features in facilities where potentially flammable materials are stored and handled. They prevent the spread of flames from one part of the system to another, reducing the risk of explosion or fire. When selecting the right flame arrestor for your application, one of the most important decisions is whether to choose an inline or final model. Both types have their advantages that are worth knowing before making a decision.

Flame arrestors are installed directly into the piping system and regulate the flow of flammable gases or vapors. They are typically used in pipelines that transport flammable materials, such as natural gas or petroleum products, at high flow rates.

Inline Flame Arrestors

The main advantage of an inline flame arrestor is its ability to handle high flow rates without compromising efficiency. However, they are not suitable for every application, as they can cause a significant pressure drop in the system.

Final Flame Arrestors

In contrast, final flame arrestors are installed at the end of a vent or stack, providing a barrier between the system and the outside environment. They are particularly suitable for systems with low flow rates of flammable materials, such as:

• Storage tanks
• Containers

Final flame arrestors are designed for large volumes of gases and vapors and do not cause a significant pressure drop in the system. They also have the advantage of preventing sparks and foreign bodies from entering the system.

Choosing the Right Flame Arrestor

So how do you make the right choice? The final decision depends on the specific application and the flow rate of flammable materials in the system. For high flow rates, an inline flame arrestor is the better choice. However, for low flow rates or storage of flammable materials, a final flame arrestor is the better choice.

It is important to remember that correct installation, maintenance and regular inspections are essential for the effective operation of flame arrestors. It is also advisable to consult an engineer to help you choose the most suitable flame arrestor for your application. By using the right fire protection, you ensure the safety of your system, personnel and the environment.
