I. Overview

A flame arrester is a device installed at the end or near the end of a pipeline, designed to prevent the vertical propagation and spread of flames. It is widely used in pipelines for heating furnace fuel gas and liquefied petroleum gas, as well as in systems for oil gas recovery, gas purification, gas analysis, and coal mine gas排放. It effectively ensures the safe operation of gas pipelines and gas usage points.

Section 3: Working Principle

Fire arresters should be installed on the pipeline before the nozzle where fuel gas or flammable liquid vapor enters. When the nozzle backfires, the stainless steel corrugations inside the fire arrester convert into heat energy due to the wall effect, extinguishing the flame, preventing the spread of flammable gas and flammable liquid vapor flames, and safeguarding against backfire-induced explosions.
