API-compliant solutions to maintain safe operationsMechanical & Asset Integrity Inspections

A mechanical integrity program employing methods of nondestructive testing to detect structural flaws in process plant equipment, can go a long way towards keeping your working environment safe. We specialize in inspecting the following types of equipment:

  • Above Ground Storage Tanks
  • Pressure Vessels
  • Piping Systems
  • Heat Exchanger & Boiler Tubes
  • API 653 / 510 / 570 Compliance

    Your team understands the need to periodically inspect tanks, pressure vessels and process piping, in keeping with American Petroleum Institute (API) recommended practices. But what happens when these inspections identify flaws, cracks or corrosion? Do you have the time and expertise in-house to identify the best path forward?

    Whether you need a simple API inspection or advanced engineering analysis, IIA can help. Our turnkey solutions help to maximize the life of your equipment and make your life easier.

    Storage Tank Inspection


    In-Service

    External inspections are carried out periodically to verify tank integrity using the following techniques:

    • Visual inspection of tank per API recommendations
    • Examination of tank foundation and compound area
    • Ultrasonic A-Scan thickness testing of shell walls and roof plates
    • Magnetic particle or liquid penetrant testing of suspect areas
    • Settlement surveys

    Out-Of-Service

    Internal inspections are carried out during outages using the following techniques:

    • Visual inspection of tank per API recommendations
    • Examination of tank foundation and compound area
    • Magnetic flux leakage (MFL) testing to locate top and bottom side corrosion on the floor plates
    • Ultrasonic A-Scan thickness testing of tank floor, shell and roof plates
    • Magnetic particle or liquid penetrant testing of suspect areas
    • Vacuum box leak testing of welds
    • Settlement surveys
