Vent-Line / In-Line Deflagration Flame Arresters

Chemoil Advance Technology supplies Vent Line In-Line Deflagration Flame Arresters from recognized manufacturers for flame propagation protection in vent lines and process piping carrying flammable gases or vapors. These devices are installed in-line within a vent or vapor pipeline and are designed to help prevent the transmission of a deflagration flame front through the protected piping system under specified operating conditions.

The flame arrester uses a specially engineered flame-arresting element to absorb heat from the flame and reduce the combustion energy as the flame passes through the element. This heat transfer helps interrupt flame propagation and provides a protective barrier between connected sections of the vent or vapor system.
