The main role of gravel pipe flame arrester is:
Prevent external flames from entering the equipment and pipes containing flammable and explosive gases.
Prevent the flame from spreading between equipment and pipes to ensure production safety.
Structure and composition
Gravel pipe arrester is mainly composed of two parts: shell and filter element:
Gravel arrestor pipeline flame arresters Shell: should have sufficient strength to withstand the impact pressure
generated by the explosion.
Filter element: It is the main component to prevent the spread of flame, and the commonly used filter types are
metal mesh filter element and corrugated filter element. Among them, the metal mesh filter is composed of
multiple layers of stainless steel or copper mesh with a diameter of 0.23~0.315mm, while the corrugated filter
is supported by materials such as stainless steel, copper-nickel alloy, aluminum or aluminum alloy. The gap or
channel of the filter element should be as small as possible so that after the flame enters the flame arrester, it is
divided into many small flame streams.
Gravel pipe flame arrester is widely used in urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage and other fields.Gravel arrestor pipeline flame arresters It is especially suitable for storage of Class A oil with flash point below 28 ° C and Class B oil with flash point below 60 ° C, such as gasoline, kerosene, light diesel, crude oil, benzene, toluene and other oil products and chemical raw materials storage tanks and pipeline systems.
