Flame Arrestor Element Allows Gas Passing and Extinguishes Flame

Different sizes of flame arrestor elements

Flame arrestor element is made of wound corrugated and flat metal strips as the main part of flame arrestor. It prevents the spread of fire by the design of its gap.

As the main component of the flame arrestor, the flame arrestor element is suitable for flammable gas pipelines, such as gasoline, kerosene, light diesel oil, crude oil and other oil storage, gas purification and emission systems of coal seam. The flame arrestor element can be used with a breathing valve.

The parameters of flame arrestor element, such as crimp height, thickness and diameter can be formulated.

Working principle

When a mixture ignites in a gap, the flame spreads towards the non-combusted mixture. The expansion in volume of the combusted mixture pre-compresses the noncombusted mixture and accelerates the flame. By heat dissipation in the gap layer of the flame arrestor element, transferring flame to the surface of the waved gap and cooling-down the product below its ignition temperature, the flame is extinguished.

Available types

There are two types of flame arrestor elements. One is made up of two corrugated strips, and the other is made up of a corrugated strip and a flat strip alternately wound into a coil.
