鏽蝕不只是外觀問題。
當管壁開始剝落、出現孔洞，
代表結構完整性已受損。

繼續使用，只會讓設備磨損更快、風險更高。

Corrosion is not just a cosmetic issue.
When the casing wall begins to flake and holes appear,
it indicates that the structural integrity has already been compromised.

Continued use will only accelerate equipment wear and increase overall risk.
