In industries where flammable gases and vapors are present, safety is paramount. A single spark or uncontrolled flame can lead to catastrophic damage, causing equipment loss, operational downtime, and potential injury. This is where an in line flame arrester becomes indispensable. Installed directly within pipelines, it prevents flames from traveling through flammable gas or vapor streams. In this guide, we explore what an in line flame arrester is, how it works, its types, installation tips, maintenance, and why choosing a trusted manufacturer like Zhen Chao flame arrester ensures maximum safety and efficiency.
What ls an In Line Flame Arrester?
Definition
An in line flame arrester is a protective device installed directly in a pipeline to stop flames from propagating through flammable gases or vapors. Unlike end-of. Line flame arresters that protect tanks and vents, in line models safeguard the internal piping system.
Operating Principle
The arrester works by forcing the flame through a flame element, often made of metal strips or wire mesh, The narrow passages absorb heat from the flame, lowering its temperature below the ignition point, and stop flame propagation while allowing gas flow to continue safely.
Main Features and Advantages
Application Scenarios
In line flame arresters are used in:
Potential Disadvantages
Types of In Line Flame Arrester
In Line Deflagration Flame Arrester
Protects against subsonic flames (deflagration)
Installed close to potential ignition sources
Ideal for low-pressure pipelines and vent systems
Cost-effective for common industrial applications
In Line Detonation Flame Arrester
Protects against supersonic flame fronts (detonation)
Can withstand high pressure and shock waves
Used in long pipelines and high-risk environments
Higher cost but superior safety performance
Design and Construction Details
Understanding the design of an in line flame arrester helps in selecting the right model:
Flame Element Material: Typically stainless steel or nickel alloys for corrosion resistance and high-temperature tolerance.
Passage Geometry: Narrow gaps or corrugated plates dissipate flame heat
efficiently.
Housing: Designed to withstand pipeline pressures while maintaining an
airtight seal.
Flame Arrester Valve Integration: Some models include valves to isolate sections during maintenance or emergencies.
Flow and Pressure Considerations
Pressure Drop: Proper sizing ensures minimal impact on gas flow.
Flow Direction Sensitivity: Correct installation direction is critical to arrester performance.
Capacity Matching: Selecting a model that matches pipeline flow and pressure ensures safety without hindering operations.
Compatibility With Different Gases
In line flame arresters are compatible with a variety of gases, including methane, propane, hydrogen, and ethanol vapors.
Deflagration Flame Arrester: Suitable for subsonic flames with lower burning velocity.
Detonation Flame Arrester: Designed to withstand supersonic flame fronts in high-pressure or high-risk pipelines.
Providing a chart with flame speeds and suitable arrester types can help industrial operators make informed choices.
How to Select the Right In Line Flame Arrester?
Consider the following factors:
1. Hazard type-Determine whether deflagration or detonation is likely.
2. Gas properties-identify flammable gas types and burning characteristics.
3. Pipeline design-Include diameter, length, and flow direction.
4. Operating conditions-Pressure, temperature, and flow rate matter.
5. Certifications-Ensure compliance with lSO, ATEX, and NFPA.
6. Maintenance accessibility-Select models that allow easy inspection and cleaning.
Consulting experts from Zhen Chao ensures the correct arrester is selected for your system.
