Hidden-Damage Inspection for Gasoline Transfer Tanks
- Visual Exterior: Scan the entire tank surface—especially welds, seams, and connection points—for hairline cracks or dents that may mask internal structural weakening.
- Pressure Test: Seal all valves, attach a gauge, and pressurize to the manufacturer’s rating. Hold for 30 minutes; any pressure drop flags possible hidden punctures or failing seals.
- Plastic Tank Check: Look for discoloration or cloudiness—signs of material degradation invisible on the surface.
- Valve & Fittings: Cycle valves repeatedly; stiffness or irregular resistance points to internal corrosion or blockage. Use a flashlight through the fill port to spot rust, sediment, or undisclosed repairs.
- Metal Tank Magnet Test: Pass a magnet over suspect areas; uneven adhesion can indicate thinning walls or internal rust.
- Professional Verification: If any anomaly appears, engage a certified inspector with ultrasonic testing tools to confirm hidden structural integrity before deployment.
