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 Superior Mechanical Strength Precise Flow Control and Pressure Restriction 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. www.mottcorp.com Mott Corporation

Porous Metal Flame Arrestors Design Requirements: Flame Arrestors are normally designed to meet a specific flow condition and can vary widely in size and shape. This allows greater flexibility in meeting constraints of custom designed devices. Devices are tested to meet several internationally recognized Standards such as Underwriters Laboratories (UL), Factory Mutual (FM) and CENELEC. Specifications and sampling plans must be determined for each Flame Arrestor application to meet the International Standards Organization (ISO) Specifications such as ISO 2738 (Density), ISO 4022...
