Pressure Vessel Inspection

• Ensure safe operation of the pressure vessel
• Detect corrosion, cracks, leaks, or deformation early to prevent accidents
• Maintain operational efficiency and reliability of the system
• Comply with industry standards, regulations, and manufacturer guidelines
• Plan maintenance, repairs, or replacements proactively

Key Inspection Steps

1. Preparation

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

2. External Inspection

• Check vessel body for corrosion, dents, cracks, or leaks
• Inspect connections, nozzles, valves, and supports
• Check surface coatings and protective layers

3. Internal Inspection

• Drain the vessel and open for internal inspection
• Look for corrosion, pitting, scaling, cracks, or deformation
• Inspect internal components such as baffles, trays, 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) / Dye Penetrant Testing (PT):Detect cracks
• Radiographic Testing (RT):Inspect welds and internal structures

5. Recording and Evaluation

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

6. Maintenance & Repair

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