Flame Arrestors: Choosing In-Line vs. End-of-Line for Safety and Compliance

Flame arrestors play a key role in preventing the spread of fire and protecting equipment and personnel in a variety of industries, from oil and gas to chemical processing. That’s why it’s important to understand the different types of flame arrestors and determine which one is best for your needs. In this article, we’ll look at the differences between end-of-line flame arrestors and help you choose the one that’s best for your application.

What are flame arrestors?

Flame arrestors are safety devices that prevent the spread of flames in piping systems where flammable gases or vapors are present. They extinguish flames by cooling the gas or vapor below its flash point while preventing it from reaching the other side of the flame arrestor. This helps minimize the risk of fire and explosion and protects both equipment and personnel.

In-line and End-of-Line Flame Arrestors

In-line flame arrestors are installed in a straight section of process piping, close to the source of the flame. They are designed to withstand high flow rates and are often used in high-maintenance applications, such as gas stations or chemical plants. Inline flame arrestors are commonly used in pipelines carrying flammable gases or liquids over long distances.

In contrast, end-of-line flame arrestors are typically installed at the end of a vent or exhaust line, where the fuel or gas is released to the atmosphere. They are designed to handle low flows and work best in applications with a steady, even flow. End-of-line flame arrestors are commonly used in storage tanks, vents, and other enclosed systems containing flammable liquids or gases.

How do you know which one is right for you?

When determining whether you need an end-of-line or in-line flame arrestor, you should consider the specific requirements of your application. Factors to consider include:

• Type of fuel or gas
• Flow rate
• Process pressure and temperature
• Any other safety regulations that may apply to your industry

Inline flame arrestors are best suited for high flow, high maintenance applications, while end-of-line flame arrestors are better suited for low flow applications and areas where there is a risk of fuel or gas escaping into the atmosphere.
