Demystifying Flame Arrestors: Understanding the Differences Between End-of-Line and In-Line Model

Flame arrestors are important safety devices to prevent explosions and fires in industrial processes where flammable gases and liquids are transported and stored. They are designed to stop the spread of flames in the event of a fire or explosion by absorbing and dissipating heat energy. This prevents the flame from reaching the source of the flammable substance, preventing a potential disaster.

Types of Flame Arrestors

There are two main types of flame arrestors used in different industries: end-of-line flame arrestors and in-line flame arrestors. Both serve the same purpose, but differ in design and functionality. In this blog post, we explain the key differences between the two types of flame arrestors.

End-of-line Flame Arrestors

• Also known as vents or vent barriers, they are installed at the end of a pipeline or tank vent to protect against the spread of flames.
• They are typically used in applications where the flow rate is low or variable and the flame front can be expected to recede along the vent line.

End-of-line flame arrestors are cylindrical in shape with a deflector plate and several layers of metal mesh filter. Their function is to extinguish flames by trapping them and cooling them so that they do not touch the flammable substance.

In-line Flame Arrestors

Also known as in-line deflagration arrestors, they are mounted in pipes or containers to prevent the spread of flames. They are often used in applications with high and uniform flow rates where the flame front is expected to travel downstream.

In-line flame arrestors are more compact in design and usually consist of a single layer of corrugated metal tape or spirally wound tape. They are designed to extinguish flames by breaking them up into smaller units, thereby reducing their intensity and preventing the flame from passing through the barrier.

Summary

In summary, both end-of-line and in-line flame arrestors play a key role in preventing potential disasters in industries where flammable substances are present. While end-of-line flame arrestors are better suited for low flow, variable temperature applications, in-line flame arrestors are better suited for high flow, constant temperature applications. It is important to understand the specific requirements of your process and select the appropriate type of flame arrestor to ensure maximum safety and protection.
