Product description
Flame arrestors for process and analytical instrument safety applications
Flame Arrestors for Process and Analytical Instrument Applications are designed as critical safety components for handling combustible gases in industrial environments. Manufactured from sintered metal powder and porous plastics, these flame arrestors are widely used in process installations, gas analysers and analytical systems.
Due to their high thermal conductivity and controlled porous structure, these flame arrestors cool the flame front or combustion wave by absorbing and dissipating heat. This prevents flame propagation and significantly reduces explosion risks in sensitive gas handling systems.
Operating principle
Sintered metal and porous plastic flame arrestors operate by forcing the flame front through a tortuous path within the porous material structure.
This mechanism provides:
rapid heat absorption and dissipation
cooling of the combustion wave below ignition temperature
prevention of flame transmission
controlled gas permeability
The combination of defined pore structure and high thermal conductivity ensures reliable flame quenching performance.
Material construction
Flame arrestors are manufactured using sintered stainless steel metal powders or engineered porous plastics, depending on application requirements.
Key material characteristics include:
uniform and controlled pore structure
excellent thermal conductivity (sintered metal)
mechanical strength and durability
corrosion resistance
dimensional stability
long service life
The tortuous internal structure enhances flame-arresting efficiency while maintaining gas flow performance.
Compliance and testing
Sintered Metal Flame Arrestors comply with the ATEX Directive and associated ISO testing standards.
Relevant standards include:
ISO 4003 – Determination of Bubble Point Pore Size in Porous Sintered Metal
ISO 4022 – Determination of Permeability
ISO 2738 – Determination of Density in Porous Materials
Products undergo SPC inspection and conform to leading international certification authorities including EECS, UL, FM, CAS and BASEEFA.
Typical applications
Flame arresting in gas handling systems
Ignition prevention in flue gas stacks
