Pipeline flame arresters, also known as fire arresters, are used to prevent external flames from entering equipment or pipelines containing flammable and explosive gases, or to prevent flames from spreading between equipment and pipelines. Pipeline flame arresters are suitable for combustible gas pipelines, such as gasoline, kerosene, light diesel, benzene, toluene, crude oil and other oil storage or flare systems, gas purification and purification systems, gas analysis systems, coal mine gas emission systems, heating furnace fuel gas pipeline networks, and can also be used as pipeline supplies for acetylene, oxygen, nitrogen, and natural gas.

How to maintain pipeline flame arresters? as shown below

1. It should be checked every six months. Check whether the fire-resistant layer has defects such as blockage, deformation, or corrosion.

2. The flow direction mark on the flame arrester must be consistent with the flow direction of the medium.

3. The blocked fire-resistant layer should be cleaned thoroughly to ensure that each hole is unobstructed, and any deformed or corroded fire-resistant layer should be replaced.

4. In order to ensure the performance of the flame arrester meets its intended use, it is necessary to carefully read the instructions provided by the manufacturer before installing the flame arrester, and carefully check whether the label is consistent with the requirements of the installed pipeline.

5. When reinstalling the fire-resistant layer, the gasket should be updated and the sealing surface should be confirmed to be clean and undamaged, without any air leakage.

6. When cleaning the flame arrester core components, high-pressure steam, non corrosive solvents, or compressed air should be used for blowing, and sharp hardware brushes should not be used.
