The Applied Technical Services Family of Companies (ATS FoC) provides API tank inspection services for aboveground storage tanks. We help owners verify structural integrity, identify deterioration, and ensure safe operation. Our inspections comply with API 653, covering inspection, repair, alteration, and reconstruction of steel tanks built to API 650 or API 12C standards. Our qualified personnel examine key tank components and use nondestructive testing to assess corrosion, wall thinning, cracking, leakage, settlement, and other deterioration.
What Types of Storage Tanks Can API Tank Inspection Services Evaluate?
API tank inspection services primarily evaluate steel, field-erected, aboveground storage tanks constructed to API 650 or its predecessor, API 12C requirements. These tanks are used in petroleum, chemical, manufacturing, energy, and bulk storage operations. Our inspections cover a wide range of tank components, including:
- Tank shells, floors, roofs, and annular plates
- Nozzles, welds, foundations, and appurtenances
API 653 inspection programs address both internal and external tank conditions to evaluate suitability for continued service.
About Our API Tank Inspection Services
Our API tank inspection services deliver a comprehensive assessment of tank condition using experienced personnel and proven inspection techniques. Depending on your needs, we perform visual examinations, ultrasonic thickness measurements, magnetic particle testing, penetrant testing, magnetic flux leakage floor scanning, and vacuum box testing. We also provide corrosion rate calculations, remaining life evaluations, settlement assessments, engineering evaluations, and fitness-for-service assessments. These services identify deterioration in tank floors, shells, roofs, welds, nozzles, and other critical areas.
Our inspection capabilities can address:
- Internal and external tank inspections
- Corrosion, thickness, settlement, and leak evaluations
How Do Inspections Help Prevent Storage Tank Failures?
API tank inspections help prevent failures by identifying damage before it affects tank integrity. Inspectors measure material thickness, locate corrosion and pitting, evaluate welds, identify foundation settlement, and assess other deterioration that could impact service. Inspection data also supports corrosion rate calculations and remaining life assessments, enabling owners to make informed decisions about repairs, maintenance, inspection intervals, or continued operation.
