Abstract: Due to the fact that the defects of liquefied petroleum gas vessel in use, such as sulfide stress corrosion crack, hydrogen blister, hydrogen induced crack and so on, may spread, it was essential to inspect the spreading situation. The ultrasonic inspecting methods to the several defects were introduced, and the key points in inspecting process were summarized.

- Sulfide stress corrosion crack /
- Hydrogen blister /
- Hydrogen induced crack
