Tank Inspection Services in Phoenix 2026 — ASNT Level III Led

Atlantis NDT delivers tank inspection services in Phoenix. Methods: UT (including PAUT and TOFD), RT, MT, PT and VT, with procedures and reports reviewed by an ASNT NDT Level III. Phoenix facilities in the semiconductor, aerospace & solar sectors require rigorous tank inspection services. Technicians are certified by their employer to its SNT-TC-1A written practice. Where we work: nationwide. Technicians are mobilised to your site anywhere in the USA; apart from the Houston office there is no local office, so mobilisation is planned and quoted for each job.

Tank Inspection Services Scope

Tank inspection covers: floor plates and bottom annulus via MFL; shell courses via UT thickness survey; roof, nozzles, and foundation via visual and settlement measurement — all per API 653, with API 650 new-construction alignment and EEMUA 159 guidance where applicable. Atlantis NDT Level III approves every Procedure + signs off final disposition + audit-ready records via Atlantis NDT ERP.

Code + Compliance

What tank inspection involves

Aboveground storage tank inspection covers the shell, floor, roof and appurtenances, establishing minimum thickness by course, floor condition, settlement, and the resulting inspection intervals under API 653.

Scope of work

External inspection of shell, roof, appurtenances, foundation and containment
Ultrasonic shell thickness by course with minimum-required-thickness calculation
Floor scanning by magnetic flux leakage with ultrasonic prove-up of indications
Settlement survey and evaluation against API 653 Annex B criteria
Vacuum box testing of floor welds and, where required, hydrostatic testing after repair

Governing codes

API 653 for inspection, repair, alteration and reconstruction, API 650 as the construction code, API 575 for practice, and API 579 where fitness-for-service assessment is required.

The Phoenix asset base

Phoenix's industrial base centers on advanced manufacturing and power rather than refining. Intel's Ocotillo campus and TSMC's new Arizona fabs in nearby Chandler are investing tens of billions in semiconductor manufacturing infrastructure, while the Palo Verde Nuclear Generating Station west of the city is the largest nuclear power plant in the US by generation. Freeport-McMoRan, headquartered in Phoenix, operates copper mining and processing assets across Arizona including the Morenci mine, adding mineral-processing vessels and heap-leach infrastructure to the region's asset base. Semiconductor fabs require ultra-high-purity piping and cleanroom infrastructure with exacting structural tolerances, while Palo Verde's reactor containment and cooling systems operate under NRC oversight requiring rigorous structural integrity documentation. Digital twins help both semiconductor fabs and power generation facilities manage complex, high-value infrastructure where unplanned downtime carries enormous cost.

How the work is controlled

Agree personnel qualification, equipment checks, procedure revision and review responsibilities for the examination. Retain those records with the results and coverage limitations.

What you receive

A report in your required format, with findings located against the component and, where relevant, against a persistent corrosion monitoring location so trends stay continuous between campaigns
Raw data in the instrument-native format plus an open export, so the dataset outlives any single supplier relationship
The procedure revision, technician certification state and instrument calibration status applicable at the time of examination
Where a finding affects continued service, the specific code clause governing the acceptance decision
