Storage Tank Inspection - API 653


Hi-Tech Testing has extensive experience with above ground storage tank inspection. All Hi-Tech inspection services are performed as specified by the American Petroleum Institute (API) Standard 653, which covers the inspection, repair, alteration, and reconstruction or above ground storage tanks.

All of our inspectors are API certified, and as inspections are performed by our inspectors, data is acquired and appropriate Non-destructive examinations are performed. This information is entered into our Inventory Calculation Organizational Network (ICON) software by Hi-Tech Testing personnel. Calculations and inspection results are evaluated by the API inspector and reports are produced. Hard copy reports can be printed and bound, or electronic reports can be loaded onto a compact disc for easy later access and minimal storage.

Available Storage Tank Inspection Services include:

  • Radiography - Conventional, computed, and digital radiography can be used for code compliance during repair, alteration as well as for new installations. Hi-Tech has technicians experienced in the specialized task of performing radiography in storage tank applications.
  • Visual Inspection (VT) - Visual examination is often used to detect mechanical damage or wear due to harsh service conditions as well as dimensionakl checks for peaking, banding, and other storage tank specific items of concern. CWI/QC services can monitor repair or installation activities to ensure code compliance.
  • Magnetic Flux Leakage (MFL) - MFL is the standard screening tool for examining in-service above-ground storage tank floors for corrosion during API-653 inspections. Using this method, both top-side and bottom-side corrosion as well as other damage resulting in material loss can be detected in both lined and unlined ferrous metallic storage tank floors.
  • Leak Testing - Hi-Tech Testing offers vacuum box testing services for storage tank floors, floor to sidewall and roof joints.. This technique works by pulling a vacuum iusing specialized equipment relying on visual observation to detect leaks. Consulting - Hi-Tech has on staff personnel with over twenty-five years in storage tank inspection experience.
