Maintenance and repair

In order to ensure the safe use of flame arresters, they should be regularly inspected and maintained.
1. The flame arrester should be inspected every six months to check whether the flame arrester core is blocked, deformed, corroded, etc.
2. The blocked fire-resistant layer core should be cleaned thoroughly to ensure that each hole on the core is unobstructed, and any deformed or corroded fire-resistant layer should be replaced.
3. When reinstalling the fire-resistant layer core, it should be ensured that the joint surface is tight and there is no air leakage.
