Gravel flame arrester is a safety device used to prevent hydrogen flame from spreading out. It is composed of a solid material (a fire element) that can be passed through a gas, with a number of tiny channels or gaps. Asked the fire element in the gap or channel as small as possible, so when the flame entered the flame arrester, fire retardant components are divided into many small fire flow, due to the heat transfer function (gas cooled) and the wall effect, the flame flow quenching.
1. The explosion resistance performance is qualified, and the fire resistance can be prevented by 13 consecutive tests.
2. The fire resistance is qualified, and the fire resistance test is 1 hour, during which there is no tempering.
3. The arameter shell shall be subjected to hydraulic test no less than 0.9mpa without leakage.
This product has reasonable structure, light weight and corrosion resistance. Easy maintenance, easy installation. Flame arrester core is made of stainless steel, which is corrosion resistant and easy to clean.
The arrestor is mainly composed of shell and filter element. The shell shall be strong enough to withstand the impact of the explosion. The filter element is the main component to prevent the flame propagation. Metal mesh filter element with diameter of 0.23~0.315mm stainless steel or copper mesh, multi-layer overlap composition. At present, arresters in China usually use 16~22 mesh metal mesh, for 4~12 layers.
Corrugated filter elements are supported by stainless steel, copper-nickel alloy, aluminum or aluminum alloy. Corrugated flame arrester can prevent the violent flame deflagration, and can withstand the corresponding mechanical and thermal action, flow resistance is small, easy to clean and replace.
