阻火器系列 Flame Arrester



Pipeline Fire safety devices applicable to the petrochemical, chemical industry, light industry and other industries combustible gas transportation process. I plant manufacturing Pipeline Fire is made after a rigorous the flame arrester theory design and precision processing machinery and equipment dedicated. Resistance deflagration and resistance detonation two categories can be divided according to fire resistance and fire retardant grade.

结构设计 Structural Design


Products offered by the two parts of the core member and the housing, the core member is a core, ultra-thin stainless steel band composed of two layers, one being pressed into a wave-N-shaped, the other it is a flat strip tightly entwined around the center. Numerous end face so as to constitute a small triangle straight through the flow channel, and the core pieces of the internal structure of a cross bracket (or in the surface pressure on the Y-shaped frame) so as to enhance the robustness of the core parts, to avoid the media are core pieces are lit the explosion generated pressure to break up. Media through the narrow channel from the triangle, the flame arrester is precisely to prevent the spread of flame in the pipeline through which the principle of the "wall effect" Rain of Fire wall collision energy conversion, lower the temperature. From this principle in the design of the height of the triangle hole to prevent the passage of flame. Flow channel length plus enough to absorb the heat of the flame to extinguish it in the core member, to avoid the possibility of the gas at the other end of the core member is recrudescence.

适用范围 Applicability


Pipeline transporting flammable gas flare systems, vapor recovery system, furnace fuel gas pipe-line, the gas purification the Tonghua system, coal mine gas drainage system and acetylene, hydrogen gas system.

阻火器类别 Flame Arrester Category



Overview: The flame arrester is installed in the petroleum, chemical industry, chemical fiber tank top with breathing valve, breathing manholes, vent supporting the use of security products. Its function is to allow gas through play to prevent the flame, the role of suffocation.


I plant the production of stainless steel flame arrestor "N"-shaped, double corrugated with flame arrester core pieces, shell material, depending on the storage medium, aluminum, carbon steel and various grades of stainless steel. Sinopec Beijing Design Institute structure, scientific and reasonable, attractive appearance. Products have repeatedly tested by the Ministry of Public Security, Tianjin Fire Science qualified and identified through scientific and technological achievements in [(99) the present,a court 02].

安装与维护 Installation And Maintenance


The Pipeline Fire and piping connections can be installed horizontally can also be mounted vertically. Periodic inspection, Once clogged, the application of high-pressure steam, compressed air, or organic solvent cleaning, such as the discovery of the core pieces of mechanical damage or corrosion medium, should be replaced immediately.

执行标准 Executive Standard





GB13347-92 "oil gas Pipeline Fire fire resistance and test methods" SH/T3413-99 "Petrochemical LPG Pipeline Fire, inspection and acceptance."

HG/T20570.19-95 "flame arrester settings."


Note: GZ-II the type resistance detonation type Pipeline Fire For media and different occasions, the structure size changes, general technical data provided by the user, first I plant design drawings, and then confirmed by the user, it is temporary dimensions.
