STI SP001: Inspection of Above Ground Storage Tanks

To properly interpret the standard, carefully carryout inspections and provide industry related reports, our inspectors must meet certain knowledge and experience requirements to be able to apply to become a certified STI SP001 Inspector through the Steel Tank Institute. Once approved, they must pass proctored examinations to gain entry into the industry as a certified inspector, something we pride ourselves on and hold with great integrity. Recertification must take place every 5 years in order to stay up to date with the latest industry standards and practices.


    Regardless of the Tank, the structure and its components will degrade overtime, increasing the probability of structural failure. Because of this degradation, inspections must take place at set intervals throughout the span of the Tank’s service life. These inspections provide great insight into the structural integrity of the tank and its components through the use of non-destructive testing and visual inspection, allowing for the preventative maintenance needed to mitigate the probability of a hazardous discharge into the environment.


      API 510 – Pressure Vessel Inspections

      The API 510 standard addresses the in-service Inspection, Repair, Alteration, and Rerating activities for pressure vessels and the pressure relieving mechanisms attached to the vessel. Thorough inspection of pressure vessels requires the use of Non-destructive testing (NDT) measures, such as Ultrasonic-Testing, Dye Penetrant and Radiographic Testing. The inspection of a pressure vessel will be required prior to being placed into service, at the time of any major repair or alteration, as well as, at the external inspection interval of 5 years, and the internal inspection interval of 10 years. 

        API 570 – Process Piping

        API 570 code addresses the inservice inspection, repair, and alteration procedures for metallic, and Fiberglass reinforced plastic (FRP) piping systems and their associated pressure relieving mechanisms. These inspections are performed by an API Certified 570 inspector, utilizing Non-destructive testing measures and include a formal report for the facilities compliance records.
