The introduction of flame arresters, what are the uses of pipeline flame arresters?

The flame arrester is generally installed in the pipeline for transporting combustible gas, or on the ventilated tank, and is a device that prevents the propagation of flames (deflagration or detonation) from passing through, and is composed of a flame arrester core, a flame arrester shell and accessories.

A car flame arrester is a safety device used to stop the flame spread of flammable gases and flammable liquid vapors. A device installed in a pipeline for transporting combustible gas, or on a ventilated tank, to prevent the passage of a flame (deflagration or detonation), consisting of a flame arrester core, a flame arrester shell, and accessories.

Flame arresters are also commonly used in pipes that transport flammable gases. If a flammable gas is ignited, the gas flame will spread throughout the network. In order to prevent this danger from occurring, flame arresters are also used.

Flame arresters can also be used in pipelines with open flames to prevent flashback accidents. But it cannot prevent the open flame of flammable gases and liquids that burn openly.

The flame arrester is mainly composed of two parts: the shell and the filter element, and the shell should have sufficient strength to withstand the impact pressure generated by the first ... The filter element is the main component to prevent the spread of flames, and there are two commonly used types: metal mesh filter element and corrugated filter element.

Flame arrester, which also has a name called fire arrester, or management flame arrester. The main function is to prevent external open flames from penetrating into the equipment, storage tanks, or pipelines containing flammable and explosive materials. Prevent these flames from spreading within these pipes, thus preventing accidental fires from occurring.

In the major cities in northern China, it is an important product and is related to the safety of the city.

Many large cities in the north have laid underground heating and natural gas pipelines, and with the role of flame arresters, the gas in these pipelines will not leak out, and the external flames cannot have a harmful effect on the gas in the pipelines. In these important cities, explosion-proof flame arresters are also installed, which are specially set up to prevent the fire from spreading inadvertently and forming backfires, resulting in violent fires.

In China, the earliest application of flame arresters is in the petroleum industry, mainly in the exploitation of some mines, and the existence of flame arresters in the storage tanks where oil is developed and stored. As we all know, these oil tanks are likely to cause large fires if they are struck by open flames or lightning. In order to prevent such phenomena, it is necessary to strengthen them with flame arresters.

With the flame arrester, these gases can be prevented from spreading outward, and without the first source, a fire cannot be formed. This is the credit of the flame arrester, of course, with the more and more mature flame arrester technology, in our country, many gas transmission pipelines, will also be widely used flame arresters, such as natural gas pipelines, etc., with flame arresters, you can prevent the spread of flames throughout the pipe network, can prevent fires from causing devastating disasters to the city.

The function 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.

The purpose of the pipeline flame arrester is to prevent the fire of the fuel gas system caused by the backfire along the fuel gas line, ** and other accidents.

The main function of pipeline flame arresters is to prevent fire from entering flammable and explosive gases or liquids, causing combustion. For example, the safety regulations stipulate that the hydrogen exhaust pipeline must be equipped with a flame arrester, which shows the role of the flame arrester in safe production.

The basic principle of a flame arrester is to use the temperature rise created by a chemical reaction to prevent fire.

When the flame is injected into the flame arrester, a large number of water molecules catch the burning heat and transfer the heat to the flame, so that the temperature in the flame is lowered.

In general, flame arresters can also absorb oxygen from the flame, because the flame cannot be maintained inside it, and the fire is suppressed.

In addition, some flame arresters can also change the partial pressure of oxygen in the flame to inhibit the spread of the flame.

In addition to typical chemical flame arresters, modern flame arresters include physical flame arresters and mechanical flame arresters.

Physical flame arresters, such as thermally expanded material slats, can stop fires by altering the heat propagation path and elastic deformation.

Mechanical flame arresters are usually sealed to stop the fire from having too much air entering the fire area, so that the fire stops.

Pipeline flame arrester, also known as fire arrester, the function of flame arrester is to prevent external flames from escaping into equipment and pipelines containing flammable and explosive gases or to prevent flames from spreading between equipment and pipelines. Flame arresters are designed and manufactured by applying the principle that when the flame passes through the narrow pores of the thermal conductor, it is extinguished due to heat loss. The flame arrester structure of the flame arrester is gravel, wire mesh or corrugated.

It is suitable for combustible gas pipelines, such as gasoline, kerosene, light diesel oil, benzene, toluene, ** and other oil storage and irrigation or flare systems, gas purification and ventilation systems, gas analysis systems, coal mine emission systems, heating furnace fuel gas pipeline networks, and can also be used in acetylene, oxygen, nitrogen pipeline supplies. This valve can be used in conjunction with a breathing valve or as a stand-alone valve. This type of valve should generally be installed horizontally or vertically in the pipeline according to the working conditions.

Main performance of pipeline flame arrester.

1. The explosion-proof performance is qualified, and the 13 consecutive explosion-proof performance tests can be fire-resistant each time.

2. The burn-resistance performance is qualified, and there is no tempering phenomenon in the burn-resistance test for 1 hour.

3. The shell hydrostatic test is qualified. This product has reasonable structure, light weight and corrosion resistance. Easy to access and easy to install. The flame arrester core is made of stainless steel, which is corrosion-resistant and easy to clean.

The flame arrester is a safety device used to stop the flame spread of flammable gases and flammable liquid vapors. Generally, it is installed in a pipeline for transporting combustible gas, or on a ventilated tank, and is a device that prevents the transmission of flames (deflagration or detonation) from passing through, and is composed of a flame arrester core, a flame arrester shell and accessories.

There are two main working principles of flame arresters: one is based on heat transfer, and the other is based on the wall effect.

The piment function of the flame arrester is: to prevent the furnace fire from backing along the fuel gas pipeline and causing the attack fire of the fuel gas system, ** and other accidents.

The principle of the flame arrester is: the flame arrester is filled with brass metal mesh, when the flame enters the flame retardant flame informant, the metal mesh has high thermal conductivity, heat absorption and dispersion of heat, so that the temperature is reduced, the flame is extinguished, and the fire arrester plays a role in fire retardation.
