Flame arrester failure mode
Thread Content
What are the failure modes of flame arrester? Are there any special standards stipulating the use of
Once the inner net of the flame arrester melts, it will become ineffective. The specific standard is not clear. We always open it for inspection during maintenance.

Repair and maintenance 1. 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. 2. The flow direction mark on the flame arrester must be consistent with the flow direction of the medium. 3. It should be inspected every six months. Check the fire-retardant layer for defects such as clogging, deformation or corrosion. 4. The blocked fire-resisting layer should be cleaned to ensure that each hole is unobstructed. The deformed or corroded fire-resisting layer should be replaced. 5. When cleaning the core parts of the flame arrester, high-pressure steam, non-corrosive solvents or compressed air should be used to clean them. Sharp hardware should not be used to clean them. 6. When reinstalling the fire-retardant layer, the gasket should be updated and the sealing surface should be confirmed to be clean and undamaged, and there should be no air leakage.
It should be inspected every six months. Check the fire-retardant layer for defects such as clogging, deformation or corrosion. Are there any standards for this?
You can judge whether it is good or bad by looking at the pressure difference between the front and rear of the flame arrester!
