Stainless steel gas flame arresterModel:FWL - 1

Product IntroductionStainless steel gas flame arresterIts performance fully complies withGB13347-92The provisions of the "Fire Resistance Performance and Test Methods of Petroleum Gas Pipeline Flame Arresters". The structure of the flame arrester is reasonable, and the flame arrester core is selected

Made of stainless steel material, corrosion-resistant and easy to clean. The shell is made of various materials such as stainless steel, carbon steel, and cast steel, which can meet the needs of different process pipelines.

flame arresterworking principleFlame arresters are designed and manufactured based on the principle that flames extinguish due to heat loss when passing through narrow pores in a thermal conductor. The function is to prevent external flames from entering the storage area

Gas equipment, pipelines, or to prevent flames from spreading between equipment and pipelines. Mainly divided into heat transfer effect and wall effect.

Heat transfer function: One of the necessary conditions for combustion is to reach a certain temperature,The ignition point. Below the ignition point,The combustion will stop. According to this principle,As long as the temperature of the burning substance is lowered to its

Below the ignition point,It can prevent the spread of flames. When the flame passes through many small channels of the flame retardant element, it will turn into several small flames. When designing the flame arrester components inside the storage tank flame arrester,Try to do as much as possible

Expand the contact area between the small flame and the channel wall,enhanced heat transfer,Reduce the flame temperature below the ignition point,Thereby preventing the spread of flames.

Wall effect: Combustion is not a direct reaction between molecules,But it is stimulated by external energy,Molecular bonds are disrupted,Generate activated molecules,The activated molecule splits back into short-lived but highly reactive free radicals,free radical

Colliding with other molecules,Generate new products,At the same time, new free radicals are generated to continue reacting with other molecules. When the combustible gas passes through the narrow passage of the flame retardant element,The collision between free radicals and channel walls

The probability of collision increases,The free radicals involved in the reaction decrease. When the channel of the explosion-proof flame arrester is narrow to a certain extent,The collision between free radicals and channel walls dominates,Due to a sharp decrease in the number of free radicals,The reaction cannot continue

conduct,That is to say, the combustion reaction cannot continue to propagate through the flame arrester.

flame arresterMain purpose: Explosion proof flame arrester is used for installation in conveying flammable gases,Like heating fuel gas,natural gas,Liquefied petroleum gas,Pipeline network for coal mine gas emissions,Also used for gas pipelines,

Prevent flame from propagating backwards in the pipeline under normal circumstances,To avoid the occurrence of sudden accidents,Tested by the testing institute,Safe flame retardant,Its speed1425m/s,speed limit1605m/s.
