Is a tank inspection date enough? A tank inspection date is not an integrity program. A June 2026 proposal from the Pipeline and Hazardous Materials Safety Administration (PHMSA) is renewing attention on how tank-inspection intervals are established. The proposal would update the edition of API Standard 653 incorporated into PHMSA’s hazardous-liquid pipeline regulations and allow …

API 653 Formal External Inspections Formal external inspections are critical for assessing the condition of large above-ground storage tanks (ASTs) and associated equipment. Conducted by certified inspectors under the API 653 standard, these inspections focus on identifying external corrosion, structural damage, leaks, and hazards to ensure tank safety and compliance. Key points about API 653 …
Do You See What We See? Tank Inspections Stop Failures Before They StartRead More
Tank inspection services traditionally focused on fuel storage (ASTs/USTs) are increasingly crossing into potable water infrastructure, think water towers, elevated tanks, and reservoirs. This shift reflects overlapping technologies, shared regulatory frameworks, and the urgent needs of aging municipal assets. TTI’s tank inspection division includes these systems in its scope, offering facilities unified expertise across fuel …
Regular formal external inspections are crucial for the safety and reliability of large above-ground storage tanks (ASTs), supplementing routine monthly and internal inspections. This article covers formal inspections, their frequencies, and requirements, helping facility managers and compliance officers understand why these inspections are essential. Corrosion rates in tanks can vary widely; average rates of 2–5 …
