I. Brief introduction of flame arrester products

It is a safety device used to prevent the hydrogen flame from spreading outwards. It consists of a solid material (fire blocking element) with many small channels or gaps that can pass through the gas. Gravel flame arresters are suitable for higher temperature and more corrosive media. The gravel flame arrester uses gravel as the flame arresting element to quench the active center of the spark by using the gas wall effect and heat conduction effect to prevent the flame from spreading and achieve the purpose of flame arrest. Pipeline flame arrester / explosion-proof ripple flame arrester produced by Beijing Jingchen factory

Reasonable structure, light weight, corrosion resistance, qualified explosion suppression performance, 13 consecutive subsonic flame tests can block fire each time. The flame arrester is easy to overhaul, convenient to install, and has a good fire resistance performance. There is no tempering in the fire resistance test for 1 hour.

Suitable for pipelines, Class A, oil products, hydrogen liquefaction products with flash point below 28 ° C, kerosene, diesel oil, and crude oil with flash point below 60 ° C, pipelines for transporting combustible gas, torch series, oil and gas Recovery system, pipe network of heating furnace fuel gas, gas purification system, gas analysis system, coal mine gas emission system.

Third, the flame arrester maintenance

1) In order to ensure that the performance of the flame arrester reaches 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 and installed pipeline requirements *.

2) The flow direction mark on the flame arrester must match the media flow direction *.

3) Check every six months. Inspect the fire barrier for defects such as blockage, deformation, or corrosion.

4) The blocked fire barrier should be cleaned to ensure that each eyelet is unobstructed. The deformed or corroded fire barrier should be replaced.

5) When cleaning the flame arrester core parts, high pressure steam, non-corrosive solvents or compressed air should be used for cleaning. Sharp hardware brushing is not allowed.

6) When reinstalling the fire barrier, the gasket should be renewed and the sealing surface must be clean and free of damage, and no air leakage should be caused.
