API 653 Inspection

API 653 Standards - Tank Inspection, Repair, Alteration, and Reconstruction, is an internationally recognized standard used world over for inspection of steel aboveground storage tanks used in the petrochemical industries. It is a specialist inspection that outlines the key requirements for maintenance and operation of storage tanks in safe working conditions guaranteeing maximum service to the owner and protecting the environment from chemical or petroleum products contamination.

The standard covers inspection, repair, alteration, and reconstruction of storage tanks built to the API Inspection  requirements after they have been put in services. Two examination schemes that can be deployed for certification of aboveground storage tanks.

  • 5 years in-service external inspection and;
  • 10 years out-of-service internal and external inspection

Routine external inspections by the owner’s personnel is also recommended to monitor the condition of the tanks, finding of which provides guidance as to when a 3rd Party API 653 inspection may be required  or when remedial repairs and/or alterations may be required before the tank failure. API 653 certified inspector with the help of a competent Nondestructive inspector deploys various non-destructive examination (NDE) techniques to assess the condition of the tank and its components. The examination techniques may include:

  • Visual
  • Ultrasonic Thickness Gauging (spot and or scan)
  • Liquid Penetrant and or Magnetic Particle
  • Radiography
  • Magnetic Flux Scan and;
  • Vacuum Box Testing

Based on the inspection findings in reference to the tank’s as-built conditions, a certified API 653 Inspector will; as much as possible, be able to make suitable recommendations and to determine the tank’s remnant life.


API 570 Inspection

API 570 Inspection certification assesses the conformity of piping systems – metallic and fibreglass reinforced plastic and their associated pressure relieving devices – to API 570 Piping Inspection Code. The Code covers in-service inspections, rating repair and alteration of piping systems that have been put in service.
