Porous Metal Flame Arrestors

Porous Metal Flame Arrestors

Flame Arrestors are safety devices that
allow flow of combustible gases while
preventing ignition. The Flame Arrestor
prevents the flame from transferring to a
different area of a device by cooling or
quenching a flame front or dampening a
combustion wave. It is designed to absorb
and dissipate the heat of a flame for
specific operating and flow conditions.

Applications:
Process and Analytical Gas Applications:
• Venting for Explosion Proof Enclosures
• Pressure Equalization for Combustible Gas Pressure Regulators
• Handling of Combustible Sample Gas for Analyzers and Monitors
• Flashback Prevention for Welding Torches
• Ignition Prevention in Gas Stacks and Storage Tank Vents
• Inhibit the Spread of Fire or Explosions in Ductwork and Process Piping
• Backfire Flame Arrestor for Marine Engines and Motors
• Oxygen Service – Special Processing Available

Uniform Porosity
Non-Shedding Media
Excellent Joint Strength and Sealing Integrity (joined to other parts)
Media maintains integrity at high temperatures

Benefits of Porous Metal:
Sintered metal materials are a popular choice because these highly engineered materials consist
of a uniform, interconnected porosity that can be fabricated to allow precise gas flow control while
providing a non-shedding, mechanically sound, media to quench the flame front. Sintered metal
provides cost effective solutions for high volume devices, especially for applications that require
the prevention of a flame front in the event that an intense explosion occurs. Porous sintered
metal media can also be formed into net shapes and easily joined to hardware to create unique
assemblies.
