Some galvanized air ducts in the electrolyzer are not allowed to be changed immediately when they are broken, because some preparation work needs to be carried out first.
1. Please check the following items first: broken parts, damage level, whether at key position, influencing area of the broken parts, whether emergency treatment is needed.
2. Deliver necessary tools and components to the maintenance site, and finish other preparation work as well.
3. Please inform relevant leaders to make some arrangements to ensure the safety production when repairing the air ducts.
Then, the damaged parts could be replaced.
