What are the commonly used flame arrestors?

Pipe flame arresters, wire mesh flame arresters, oil storage tank flame arresters, corrugated flame arresters, and flame arrestor tubes

Safety water seals, flame arrestors, breathing manholes, flame-arresting breathing valves, vent caps, flame arrestant packs, etc

It includes flame arresters, safety liquid seals, check valves, flame arrestor gates, etc

We only know how to use it; we have never studied its specific structure in detail. To those upstairs, I’ve learned this from a handshake search; I hope it’s helpful. A flame arrester is a safety device that prevents the spread of flames from combustible gases and flammable liquid vapors, as well as stops backflow that could lead to explosions. Flame arresters are available in several types, including metal mesh flame arresters, corrugated metal sheet flame arresters, and gravel flame arresters. The fire extinguishing principle of a flame arrester is that when a flame passes through a narrow opening, the sudden increase in heat loss due to cooling causes the combustion to stop. The factors affecting the performance of a flame arrester are the thickness of the flame arrestment layer and the size of its pores or channels. 1. The screen flame arrester is installed on the pipeline before the fuel gas or flammable liquid vapor enters the nozzle. When the nozzle backfires, the metal mesh inside the flame arrester converts heat energy due to the wall effect, which extinguishes the flame; this prevents the spread of flames from combustible gases and flammable liquid vapors and stops explosions caused by backfiring. 2. Wave-shaped packing pipe flame arrester: The flame-arresting core is made of stainless steel wave-shaped packing. Its working principle is that when a gas pipeline catches fire for some reason, the flame spreads along the pipeline toward the unburned gas; as it passes through the flame arrester, the flame is extinguished when it enters the triangular pores of the wave-shaped packing (i.e., extinguishment through the pores), thereby achieving the effect of preventing fires. The flame is prevented from passing through due to the \"intermediate pore effect,\" and its temperature drops rapidly because of the \"wall effect,\" thereby stopping the spread of the flame. 3. The flame arrester consists of a valve body casing and a flame-arresting core; depending on the type of pipeline and the flammable gas involved, the structure of the internal flame-arresting core layer varies.

Refer to the \"Catalogue of Safety Facilities for Hazardous Chemicals Construction Projects\": ⑻ Fire spread prevention facilities such as flame arresters, safety water seals, backflow preventers, oil (fire) barriers, explosion-proof walls and doors and other explosion isolation facilities, as well as firewalls, fire doors, steam curtains, water curtains and other facilities, and fire-resistant material coatings.
