What needs to be examined during an internal inspection of your vessel?

The activities included in an internal inspection include visual examination, glass thickness measurement, and spark testing.

Visual examination usually consists of a technician entering a vessel, however, there are some instances when remote visual inspection via cameras is used. Here we’ve outlined the issues to look for during the following visual examination procedures:

Inspection of plugs and patches

• Loosening and corrosion
• Spaces between the repair and the glass surface
• Embrittlement of tantalum
• Rust stains around edges

Mechanical Seal and Agitator Drive Inspection

(Note: Mechanical seal should be removed to enable full inspection. During inspection of drive gearing, oil should be changed)

• Leakage or damage
• Corrosion in mechanical seal area of the agitator and under split-ring flanges
