Pipe anti Explosion corrugated flame arresting is a safety device to prevent the flame spread of flammable gas and liquid and prevent tempering and cause explosion. It is usually installed on pipelines that transport or discharge flammable and explosive gases, such as flares, heated combustion systems, petroleum gas recovery systems, or other flammable gas systems.Pipe anti Explosion corrugated flame arresting, also known as fire extinguisher, is to prevent external flame from entering the equipment, pipelines or flames that contain flammable and explosive gases or to prevent flame from spreading between equipment and pipelines. It is a safety device used to prevent the flame from spreading outwards. It consists of a solid material (fire arresting element) that can pass through the gas and has many fine passage gaps.
Regarding the working principle of the flame arresting, there are mainly two viewpoints: one is based on heat transfer; the other is based on the wall effect. Pipe anti Explosion corrugated flame arresting is designed and manufactured based on the principle that the flame passes through the narrow hole of the heat conductor and is extinguished due to heat loss. Pipe anti Explosion corrugated flame arresting is mainly composed of a casing and a fire-resistant version. The housing should be strong enough to withstand the impact of the explosion. Corrugated fire retardant fire plates are supported by stainless steel, copper-nickel alloy, aluminum or aluminum alloy. Pipe anti Explosion corrugated flame arresting can block the violent flame of detonation and can withstand the corresponding mechanical and thermal effects, with low flow resistance and easy to clean and replace.
The explosion-proof performance is qualified. The 13-time explosion-proof performance test can prevent fire at each time; the burning resistance is qualified, and the burning resistance test has no tempering for 1 hour; the shell hydraulic pressure test is qualified; the structure is reasonable, light weight and corrosion resistance. Easy to repair and easy to install.

The fire-proof performance of the Pipe anti Explosion corrugated flame arresting is regularly tested by 13 subsonic flame tests in a row, in line with national standards; Pipe anti Explosion corrugated flame arresting
is protected from wear and tear on the flange sealing surface before leaving the factory, and the plastic protective cover for the import and export is on site. Be sure to remove the blue flange protection cover after installation;
In order to facilitate on-site installation, our company has adjusted the fire-resistant core parts, which is not affected by the direction of the gas. The site can be directly installed on the required pipeline according to the flange standard. The Pipe anti Explosion corrugated flame arresting is generally installed at a distance burning. The position of the furnace is about 5-10m, which can be installed horizontally or vertically. The pipeline installed in the Pipe anti Explosion corrugated flame arresting must be clean, and there should be no impurities, dirt and other things blocking the gap of the fire-resistant core member and affecting the normal use of the flame arresting. In order to ensure the fire retarding effect of the Pipe anti Explosion corrugated flame arresting, it should be checked every six months. Check the fire barrier for defects such as blockage, deformation or corrosion. The blocked fire-retardant layer should be cleaned to ensure that each hole is unobstructed, and the fire-resistant layer that is deformed or corroded should be replaced. When cleaning the Pipe anti Explosion corrugated flame arresting core parts, it should be purged with high-pressure steam, non-corrosive solvent or compressed air, and should not be brushed with sharp hardware.
When re-installing the pipe anti Explosion corrugated flame arresting, the gasket should be renewed and the sealing surface should be clean and free from damage and air leakage.
When ordering, please confirm the following parameters: 1. Nominal diameter 2. Working pressure 3. Material 4. Flange standard 5. Media To provide you with the products that meet the requirements.
