ZGB corrugated flame arrester

Introduction of pipeline flame arrester:
Pipeline flame arrestor, also known as fire arrester, is to prevent external flames from entering equipment and pipelines containing flammable and explosive gases or to prevent flames from spreading between equipment and pipelines. It is a safety device used to prevent the spread of hydrogen flames. It is composed of a solid material (fire-stop element) that can pass gas and has many small channels or gaps. Pipeline explosion-proof flame arrester is a safety device used to prevent the spread of flammable gas and liquid flame and to prevent backfire from causing an explosion. It is usually installed on pipelines that convey or discharge flammable and explosive gases. Such as torches, heating combustion systems, petroleum gas recovery systems or other flammable gas systems.
Flame arresters are widely used in pipelines for heating fuel gas, natural gas, and liquefied petroleum gas, as well as systems for oil and gas recovery, coal mine gas emissions, gas analysis, etc., which can effectively ensure the safe operation of gas pipelines and gas use points. The function of the pipeline flame arrester is to prevent the flame spread of combustible gas and flammable liquid vapor and to prevent backfire from causing an explosion. It is usually installed on the fuel gas main line in front of the furnace. It is usually a short pipe with a larger diameter than the fuel gas line and flanges at both ends. In the pipe, about ten pieces of copper wire mesh are installed perpendicular to the airflow. The thick cast aluminum ring compresses the periphery of the mesh and forms a certain interval. Due to the excellent heat dissipation performance of the copper mesh, when the flame encounters the copper mesh, the flame will be extinguished due to a sharp drop in temperature, thereby playing the role of fire resistance. Its main function is to allow the passage of flammable and explosive gases and prevent suffocation of the flames introduced into the storage tank from the outside. This kind of pipeline flame arrester can be used under low temperature conditions in high-cold areas, and it can be matched with the snorkel or used alone. It is suitable for storage of Class A oil products with a flash point of less than 28℃ and Class B oil products with a flash point of less than 60℃. It is also suitable for storage materials on dome tanks with nitrogen topped. The principle of gravel flame arrester and net flame arrester Same as above for pipes.
Pipeline explosion-proof flame arrester is designed and manufactured by applying the principle of extinguishing due to heat loss when the flame passes through the narrow pores of the thermal conductor. The pipeline explosion-proof flame arrester is mainly composed of two parts: a shell and a filter element. The shell should have sufficient strength to withstand the impact pressure generated by the explosion. The corrugated filter element is supported by stainless steel, copper-nickel alloy, aluminum or aluminum alloy. The corrugated flame arrestor can organize the violent flame of deflagration, and can withstand the corresponding mechanical and thermal effects, has low flow resistance, and is easy to clean and replace.


Application scope of corrugated flame arrester:
The corrugated flame arrestor is suitable for pipelines, Class A, oil products, hydrogen-oxygen liquefied products with a flash point below 28°C, and kerosene, diesel, toluene, crude oil, etc., with a flash point below 60°C. It can be used with breathing valves, and It can be used alone, on the vent pipe of the inner floating roof oil tank, and on the vent pipe of the underground oil tank in the gas station.


Corrugated flame arrester performance and characteristics:
The corrugated flame arrester has reasonable structure, light weight, corrosion resistance, and qualified explosion resistance performance. It can stop the fire every time with the subsonic flame test for 13 consecutive times.
The corrugated flame arrester is easy to overhaul, easy to install, and there is no need to remove the breathing valve during inspection. The burning resistance is qualified, and there is no tempering in the burning test for 1 hour.
The core of the corrugated flame arrester is made of stainless steel, which is corrosion-resistant and easy to clean. The shell water pressure test is qualified.


Principles of pipeline explosion-proof flame arrester repair and maintenance:
(1)The flow direction mark on the flame arrestor must be consistent with the flow direction of the medium.
(2)In order to ensure that the performance of the flame arrester meets the purpose of use, before installing the flame arrester, you must carefully read the instructions provided by the manufacturer, and carefully check whether the label is consistent with the requirements of the installed pipeline.
(3)Check once every six months. Check whether the fire barrier is blocked, deformed, or corroded.
(4)The blocked fire barrier should be cleaned to ensure that each hole is unblocked, and the deformed or corroded fire barrier should be replaced.
(5)When cleaning the core parts of the flame arrester, high-pressure steam, non-corrosive solvent or compressed air should be used for blowing, and sharp hardware brushing should not be used.
(6)When reinstalling the fire barrier, the gasket should be updated and the sealing surface should be clean and undamaged, and no air leakage should be allowed.
Analyzing the standards and technical parameters of flame arresters, since they were first used in the petroleum industry in 1928, they have been widely used in petroleum and chemical plants due to their simplicity and ease of use.
What are the ten prohibitions of flame arresters in chemical companies?
One: Factory
No drinking or snacking; no bringing children; no private work; no slippers or leather shoes; no chatting for fun; no reading non-business books; no leaving posts, shifting posts, sleeping posts; no unauthorized work Shift shifts and types of work; no non-working clothes or vests are allowed to work; no shawls and long hair are allowed to work.
Two: Production area
Strong open flame management, smoking is not allowed in fire and explosion-proof areas. Vehicles without a flame arrestor are not allowed to drive in the no-fire zone. During working hours, it is not allowed to sleep, do private work, leave work, and do anything unrelated to production. Drinking is not allowed before or in class. It is not allowed to use gasoline and other highly volatile combustibles to scrub equipment, utensils and clothing. Do not wear labor protection equipment (including work clothes, work shoes, work caps, etc.) in accordance with factory regulations and are not allowed to enter production positions. Equipment with incomplete safety devices is not allowed to be used. The equipment not in charge of oneself is not used. If safety measures are not implemented when overhauling the equipment, the overhaul is not allowed. The equipment after shutdown for maintenance is not allowed to start without thorough inspection

At present, people know that flame arresters are more commonly used in gas discharge systems. In fact, there are many uses for flame arresters, but they are usually not paid attention to. Flame arrestor is also called fire arrester, mainly because its function is to prevent flames from entering inflammable and explosive equipment or to prevent flames from spreading. In fact, to put it bluntly, a flame arrestor is a safety device. The development of science and technology nowadays has also brought new equipment to meet people's growing needs, and flame arresters are constantly being updated and improved, striving to exert greater effectiveness.
