Industrial flame arresters for tank vents and process piping handling compatible flammable gases or vapours. Choose inline or end-of-line flame arrester configurations and suitable body / element materials for the application.
Flame Arresters are designed to prevent flame propagation through pipelines, vent lines and storage-tank breathing systems handling flammable gases or vapours.
Crimped ribbon and bird-mesh element options
Inline and end-of-line installation configurations
Flame Arresters are designed to prevent flame propagation through pipelines, vent lines and storage-tank breathing systems handling flammable gases or vapours.
The arrester uses a crimped ribbon or bird-mesh element to absorb and dissipate flame energy, helping stop the flame front from travelling further through the system.
Available in inline, end-of-line and breather-valve-combined configurations, the product can be supplied in multiple sizes, body materials and element materials. Carbon-steel, stainless-steel and PTFE-coated body options are available, with SS304, SS316 and Hastelloy C-276 flame-arresting elements for different process requirements.
How it works
Working Principle
Normal vapour passes through narrow passages in the metallic flame element. If a flame front reaches the element, heat is transferred into the metal matrix until the combustion temperature falls below the level required for propagation.
01
Normal vapour flow
Process vapour or vent gas passes through the arrester element during normal operation.
02
Flame enters the element
A flame front is divided into small channels formed by the wound crimped metal ribbon construction.
03
Heat is quenched
The metal absorbs and conducts heat away, reducing the flame temperature and stopping propagation to the protected side.

Questions & Answers
What is the purpose of a Flame Arrester?
It is designed to help stop flame propagation through a compatible vent or process line by quenching the flame within the metallic element.
What is the difference between inline and end-of-line types?
An inline arrester is installed within piping, while an end-of-line arrester is installed at a vent termination exposed to atmosphere.
Which element types are available?
Crimped-ribbon and bird-mesh element constructions are available according to the application.
Which materials are available?
Body options include carbon steel, stainless steel and PTFE-coated construction. Element options include SS304, SS316 and Hastelloy C-276.
What information is needed for selection?
Provide the service, gas or vapour, line size, installation position, pressure, temperature, connection, body and element materials, and applicable site safety requirements.
