Pipeline Inspection Services in Phoenix 2026 — ASNT Level III Led

Atlantis NDT delivers pipeline 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 pipeline 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.

Pipeline Inspection Services Scope

Pipeline inspection covers: girth weld examination by UT, PAUT and RT; wall-loss measurement by UT thickness and corrosion mapping on above-ground sections and at integrity digs; surface-crack examination by MT — all per API 1104, ASME B31.4/B31.8, and 49 CFR 192/195 where applicable. In-line inspection tool runs are made by ILI vendors; excavation is by the dig contractor. Atlantis NDT Level III approves every Procedure + signs off final disposition + audit-ready records via Atlantis NDT ERP.

Code + Compliance

Pipeline Inspection Services per: ASME B&PV Sections V + VIII + IX + XI; ASME B31 piping series; API 510 + 570 + 571 + 579 + 580 + 581 + 653 + 1104 + 1169; ASTM E-series; ISO 17635/17636/17640; AWS D1.1/3.6; IACS Rec-20 marine; NACE MR0175 + MR0103 sour-service.

What pipeline inspection involves

Pipeline inspection establishes the condition of a line along its length, combining in-line inspection where the line is piggable with direct assessment where it is not, and verifying both against excavation findings.

Scope of work

In-line inspection data review and dig prioritisation from MFL, ultrasonic and crack-detection runs
Guided wave screening of cased crossings and inaccessible sections
Dig verification with ultrasonic wall measurement and magnetic particle crack examination
Coating and cathodic protection survey interpretation
Girth weld examination by automated ultrasonic testing or radiography on new construction

Governing codes

ASME B31.4 and B31.8 for design and operation, B31.8S for integrity management, API 1104 for welding, and the applicable regulator's integrity management rule.

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
