Air Tank Inspection

• Ensure safe operation of the air tank and connected systems
• Detect corrosion, cracks, or leaks early to prevent accidents
• Maintain operational efficiency and system reliability
• Comply with laws, safety standards, and industry regulations
• Plan maintenance and replacement proactively

Key Inspection Steps

1. Preparation

• Review maintenance history and operational records
• Ensure inspection tools are ready (Ultrasonic, Thickness Gauge, Visual tools)

2. External Inspection

• Check tank body for corrosion, dents, cracks, or leaks
• Inspect connections, valves, pressure gauges, and supports
• Check surface coatings and protective layers

3. Internal Inspection

• Drain the tank and open for internal inspection
• Look for corrosion, scaling, cracks, or pitting
• Inspect internal baffles or supports if present

4. Non-Destructive Testing (NDT)

• Ultrasonic Thickness Measurement (UTM):Measure wall thickness
• Visual Testing (VT):Detect surface defects
• Magnetic Particle Testing (MT) or Dye Penetrant Testing (PT):Detect cracks (if applicable)

5. Recording and Evaluation

• Record all defects, thickness measurements, and anomalies
• Evaluate tank safety and remaining service life
• Prepare a maintenance or repair plan

6. Maintenance & Repair

• Clean internal surfaces and remove corrosion
• Repair or replace damaged parts
• Test the tank (hydrostatic or pressure test) before returning to service
