NDT Inspection Services in Michigan

In brief: Atlantis NDT carries out non-destructive testing for plants, mills, utilities, pipelines and fabricators across Michigan, from Detroit and Downriver to the Great Lakes Bay Region, West Michigan and the Upper Peninsula. Services cover ultrasonic thickness and corrosion surveys, phased array (PAUT) and TOFD weld examination, magnetic particle, penetrant, visual and eddy current testing, and radiography performed by radiography crews licensed in Michigan. Every job runs on Level III-approved procedures, uses ASNT-certified technicians, and ends in a code-referenced digital report.

Michigan's inspection market looks nothing like the Gulf Coast. The state has a single crude refinery, but it has one of the largest chemical complexes in the Midwest, the biggest underground natural gas storage capacity of any state, three nuclear sites on its lake shores, a heavy coal-and-gas utility fleet, integrated and mini-mill steelmaking, an automotive and battery manufacturing base that is being rebuilt plant by plant, and a winter that turns corrosion under insulation and freeze-thaw damage into routine findings. Those assets are owned by very different organisations, and each asks for something slightly different from an NDT contractor. This page sets out where the work is, which methods and codes apply, who regulates what in Michigan, and how we scope a job. If you already know what you need, send us your Michigan inspection request.

Where inspection work is in Michigan

Direct answer: Michigan inspection demand clusters in six areas: Detroit, Downriver and the Rouge industrial corridor; Monroe and the Lake Erie shoreline; the Great Lakes Bay Region around Midland, Saginaw and Bay City; West Michigan from Grand Rapids to the lakeshore nuclear plants; the Lansing and I-94 manufacturing belt; and the northern Lower Peninsula and Upper Peninsula, with pipelines, gas storage, mines and paper mills.

Detroit, Downriver and the Rouge

Southwest Detroit is home to the Marathon Detroit refinery, the only operating crude refinery in Michigan, surrounded by terminals, rail racks and product pipelines. Along the Rouge River and Downriver communities sit steelmaking at Dearborn, chemical sites such as BASF's Wyandotte operations, cement and aggregate terminals, wastewater treatment plants and the assembly and stamping plants of the Detroit automakers and their tier suppliers. Refinery and terminal work is classic mechanical-integrity NDE: thickness readings at condition monitoring locations on process piping, weld examination after repairs and tie-ins, and API 653 tank work. Steel and automotive sites generate a different mix: magnetic particle and ultrasonic inspection of crane runways, press frames, ladles and rolling-mill components, weld inspection on structural steel to AWS D1.1, and shaft and gear inspection during planned outages. Large crossings over the Detroit River, including the new Gordie Howe International Bridge, keep structural weld inspection and bridge-related NDT in demand around the city.

Monroe and the Lake Erie shoreline

Monroe County hosts one of the largest coal-fired generating stations in the country at Monroe and the Fermi 2 nuclear plant near Newport. Fossil units need boiler tube thickness surveys, header and steam-line weld examination, and inspection of high-energy piping, ductwork and coal-handling structures during spring and autumn outages. Nuclear work is governed by the owner's ASME Section XI programme and its own qualification requirements; independent contractors normally support balance-of-plant and non-safety scopes unless the owner qualifies them for more.

Great Lakes Bay Region: Midland, Saginaw and Bay City

Midland is built around Dow's Michigan Operations, a large chemical manufacturing complex, with polysilicon production at Hemlock Semiconductor nearby and chemical, food and materials plants spread through Saginaw and Bay County. Chemical units bring a heavy load of pressure vessels, heat exchangers, process piping and storage tanks, much of it in stainless and alloy steels where penetrant testing and PAUT matter. Corrosion under insulation is a persistent theme on lines that cycle between warm process temperatures and Michigan winters. Saginaw's castings and powertrain plants and Bay City's port terminals add machinery and structural scopes.

West Michigan: Grand Rapids, Muskegon and the lakeshore

The Grand Rapids, Holland and Muskegon area is a dense manufacturing region with aerospace electronics and structures suppliers, office-furniture and automotive component makers, foundries, food processing and paper converting. Aerospace parts flow down customer NDT requirements, often NAS 410-based, while foundries and fabricators need UT, MT and PT on castings and weldments. Along the shoreline sit the D.C. Cook nuclear plant at Bridgman, the Palisades plant near Covert, where Holtec has been working through its return-to-service programme, and the Ludington pumped storage plant, whose penstocks and mechanical equipment are classic structural NDT subjects. Kalamazoo and Portage add pharmaceutical manufacturing with stainless piping and vessels.

Lansing and the I-94 manufacturing belt

Mid-Michigan combines vehicle assembly around Lansing, battery cell manufacturing, power generation, university campuses with central heating plants, and a long belt of machining, casting and fabrication shops from Jackson through Battle Creek toward Kalamazoo. Typical requests are weld inspection on new structural steel and equipment skids, boiler and pressure-vessel NDE for campus and industrial steam systems, and ultrasonic testing of rotating equipment and press components during scheduled shutdowns.

Northern Michigan and the Upper Peninsula

North of the Saginaw Bay line the work changes again. Michigan holds the largest underground natural gas storage capacity in the United States, with storage fields, compressor stations and transmission lines feeding the Midwest. Enbridge's Line 5 crosses the Straits of Mackinac, the Antrim Shale and other gas fields have gathering systems and processing plants, and the Upper Peninsula has the Tilden iron mine near Ishpeming, the Eagle nickel-copper mine, paper and pulp mills, and the Soo Locks at Sault Ste. Marie, which serve the Great Lakes bulk fleet. Pipeline welds, compressor-station piping, mining equipment, mill digesters and recovery boilers, and vessel and dock structures all need periodic NDT. Distances and winter access mean scopes are best planned in campaigns.

NDT methods we deliver in Michigan

Direct answer: Atlantis performs UT thickness and corrosion mapping, conventional shear-wave UT, PAUT, TOFD, radiography via radiography crews licensed in Michigan, MT, PT, VT and eddy current. The table shows how each method is typically used on Michigan assets and the code or standard most often cited. Method choice is confirmed with your inspector of record or engineer during scoping.

All techniques are performed to written procedures approved by an ASNT NDT Level III, by technicians certified under an SNT-TC-1A written practice. If your plant uses its own procedures or requires technique demonstrations before work starts, we qualify to those. City-level method pages exist for ultrasonic testing in Detroit, radiographic testing in Detroit, magnetic particle testing in Detroit, penetrant testing in Detroit, eddy current testing in Detroit and visual testing in Detroit.

API 510, 570 and 653 inspection support in Michigan

Direct answer: For Michigan owners running API 510, API 570 or API 653 programmes, Atlantis supplies the nondestructive examination those inspections are built on, including thickness data, weld examination, tank floor follow-up and visual findings, and passes the documented results to the owner's API-certified Authorized Inspector. That inspector stays the inspector of record and signs the inspection report.

Pressure vessels (API 510). Chemical reactors, columns, drums and exchangers in the Great Lakes Bay Region, refinery vessels in Detroit and process vessels at food, pharmaceutical and gas-processing plants all follow similar patterns. We take UT thickness at each vessel's CMLs, examine nozzle and attachment welds with MT or PT during entries, apply PAUT or TOFD where cracking, prior repairs or service conditions justify it, and record external visual condition including insulation and supports. Readings are reported beside the previous survey so your inspector can work out corrosion rates and intervals. More detail: API 510 pressure vessel inspection support and pressure vessel inspection in Detroit.

Process piping (API 570). In Michigan the biggest piping risk is often external: insulated lines that sit cold and wet for months, then warm up, are prime CUI candidates. We survey CMLs to your isometrics, add scanning at injection points, deadlegs and soil-to-air interfaces where your programme requires it, and support CUI campaigns with UT once insulation is stripped. Results are delivered per CML for import into your inspection data system. See API 570 piping inspection support and piping inspection in Detroit.

Storage tanks (API 653). Michigan's tank population sits mostly at Detroit-area terminals, refinery and chemical tank farms, utility fuel-oil storage and pipeline breakout stations. For out-of-service work we perform floor scanning with UT prove-up, shell course thickness, shell-to-bottom and repair weld examination, and nozzle work; for in-service externals we measure shell thickness, inspect the shell, roof, foundation and appurtenances, and take settlement readings for your inspector's Annex B evaluation. Frost heave at the foundation and ice damage to roofs and appurtenances are Michigan-specific items worth adding to the checklist. See API 653 tank inspection support and tank inspection in Detroit.

Atlantis does not provide risk-based inspection (API 580/581) studies or fitness-for-service (API 579) assessments. We give your engineers well-organised, traceable data; integrity decisions stay inside your programme.

Turnarounds, shutdowns and planned inspection

Direct answer: Michigan inspection work follows two calendars: refinery and chemical turnarounds, and utility outages, which both favour spring and autumn because summer demand and winter conditions make those seasons hard. Atlantis joins at the planning stage, agrees methods and procedures, and mobilises crews to your site on the dates fixed during scoping.

Weather drives more of the planning here than in southern states. Outdoor tank, pipeline and structural work in January and February means cold-weather couplant, heated enclosures for some techniques, and attention to temperature limits: standard penetrant procedures under ASME Section V are qualified for a limited temperature range, and work outside it needs a procedure qualified for the actual conditions. Snow cover and frozen ground also complicate access to tank foundations and pipeline digs. Our advice to Michigan owners is to move as much on-stream work as possible, such as thickness surveys, external visual and many weld examinations, into the warmer months ahead of an outage, so the outage itself carries only the work that needs isolation or entry.

Utility outages have their own rhythm. Fossil plants schedule boiler inspections around reduced spring and autumn load; nuclear plants run refuelling outages on cycles set by the owner, with tight contractor processing and training requirements that start weeks before the outage. Chemical plants in Midland and the Detroit refinery plan turnarounds years ahead, with NDE scopes frozen months before the start date. Manufacturing plants, especially automotive, often have short windows around summer and year-end shutdowns, when presses, cranes and furnaces are available. Tell us which calendar you work to and we will plan backwards from it. Plan a Michigan outage or shutdown inspection.

Michigan regulations that shape inspection

Direct answer: In Michigan, boilers fall under the Michigan Boiler Code enforced by the Boiler Division of LARA's Bureau of Construction Codes; Michigan is not an NRC Agreement State, so NRC Region III licenses radioactive sources; the Michigan Public Service Commission oversees intrastate gas pipelines with PHMSA; and MIOSHA enforces process safety management through General Industry Part 91.

Boilers and pressure vessels: LARA Boiler Division

The Boiler Division within the Department of Licensing and Regulatory Affairs (LARA) Bureau of Construction Codes administers the Michigan Boiler Code, including installation permits, in-service inspections of boilers, repairs and accident investigations, with the ASME Boiler and Pressure Vessel Code and the National Board Inspection Code adopted by reference. The state programme is centred on boilers; for unfired pressure vessels, inspection is usually driven by owner-user programmes built on API 510, insurer requirements and process safety rules. Confirm whether a specific item falls under state jurisdiction with the Boiler Division. Repairs and alterations to code items are made by organisations holding the appropriate National Board authorisation, with NDE performed to the construction or repair code.

Radiography: a non-Agreement State

Michigan is one of the few states that has not signed an Agreement with the U.S. Nuclear Regulatory Commission. Radioactive material licences for industrial radiography sources such as iridium-192 are therefore issued and inspected by the NRC through its Region III office, and radiographers using those sources work under NRC rules in 10 CFR Part 34. Industrial X-ray machines are a state matter and are registered with Michigan's radiation safety programme; responsibilities have moved between state departments over the years, so confirm the current registering agency before an X-ray job. Atlantis does not claim to hold any radioactive material licence or registration in Michigan: radiography on our scopes is performed by radiography crews licensed in Michigan (or under NRC licence for source work), working to Atlantis procedures with Level III review. Where an exclusion zone would disrupt a running unit, PAUT or TOFD may replace radiography if your code and owner accept it.

Pipelines: MPSC and PHMSA

The Michigan Public Service Commission's gas safety programme acts as PHMSA's state partner for intrastate natural gas pipelines and distribution systems, while PHMSA regulates interstate gas and hazardous liquid lines directly under 49 CFR Parts 192 and 195, including the large liquids lines that cross the state. New-construction girth welds normally follow API 1104. See pipeline inspection services and pipeline inspection in Detroit.

Process safety, tanks and the environment

Michigan runs its own occupational safety and health plan. MIOSHA's General Industry Part 91 adopts the federal process safety management standard (29 CFR 1910.119) by reference, so covered processes need mechanical integrity procedures, inspection and testing to recognised and generally accepted good engineering practice, and documentation of every inspection. Aboveground oil storage is subject to EPA's SPCC rule (40 CFR Part 112), which expects integrity testing to an industry standard such as API 653 or STI SP001, and the Department of Environment, Great Lakes, and Energy (EGLE) administers state rules on storage tanks and the protection of the Great Lakes watershed, which raises the stakes on any tank or pipeline release.

Inspection reports clients can use

Direct answer: Each Michigan job ends with a digital report built in Atlantis's own reporting platform. Every reading, indication and photograph is linked to the asset, location, procedure, technician certification and instrument calibration, the governing acceptance criteria are quoted, and the report is reviewed under ASNT Level III oversight before release.

A report is only useful if the inspector of record, an auditor, an insurer or a MIOSHA compliance officer can follow it without calling the technician. That is why we tie every thickness reading to a named CML, every indication to the procedure and acceptance criterion applied, and every result to the technician's certification and the instrument's calibration record. Field data is captured digitally, offline where plant networks are unavailable, and structured per asset, so it can be exported to your inspection data management system rather than retyped. Read about the platform on our NDT inspection software page or compare tools in best NDT reporting software 2026.

Because Atlantis also builds business software, the data can go further than a PDF. Results can feed scheduling, certification tracking and invoicing in Atlantis ERP for Michigan inspection companies, or be placed on a 3D model of the unit in our digital twin platform; see digital twins in Michigan and digital twins in Detroit. One provider covering Level III-led inspection, the digital report and an optional twin is rare among inspection contractors.

Frequently asked questions about NDT inspection in Michigan

What NDT inspection services does Atlantis provide in Michigan?

UT thickness and corrosion mapping, conventional UT, PAUT, TOFD, radiography through radiography crews licensed in Michigan, MT, PT, VT and eddy current, plus NDE support for API 510, API 570 and API 653 programmes and pipeline work, all under ASNT Level III oversight.

Does Atlantis have an office in Detroit or Grand Rapids?

No. Atlantis has no physical office or laboratory in Michigan. Crews are mobilised to your site anywhere in the state, and the schedule is agreed during scoping.

Is Michigan an NRC Agreement State for radiography?

No. Michigan has not signed an Agreement with the NRC, so licences for radioactive sources used in industrial radiography are issued by the NRC through Region III. Industrial X-ray machines are registered with the state. Radiography on our jobs is carried out by appropriately licensed radiography crews.

Who inspects boilers in Michigan?

The Boiler Division of LARA's Bureau of Construction Codes administers the Michigan Boiler Code, including permits and in-service inspections. For unfired pressure vessels, inspection is usually driven by owner programmes based on API 510, insurers and process safety rules; confirm jurisdiction for specific items with the Boiler Division.

Can you perform API 653 tank inspection in Michigan?

We perform the NDE an API 653 inspection relies on, including floor scanning with UT prove-up, shell thickness, weld examination and settlement measurement. Your API 653-certified Authorized Inspector remains the inspector of record and signs the report.

Can NDT be done in a Michigan winter?

Yes, with planning. Cold affects couplants, penetrant temperature limits and access to foundations and digs, so outdoor scopes may need heated enclosures or procedures qualified for low temperatures. Where possible we move on-stream work into warmer months ahead of an outage.

Do you inspect for corrosion under insulation?

Yes. We support CUI programmes with visual inspection, UT thickness and corrosion mapping once insulation is removed, focusing on locations your programme identifies, such as low points, supports and damaged jacketing.

How much does NDT inspection cost in Michigan?

Atlantis quotes on request. Cost depends on the method, the number of locations or welds, access requirements, travel to the site, crew size, schedule, weather protection and report format. Send the scope and you will receive a written quote.

Who regulates pipelines in Michigan?

The Michigan Public Service Commission oversees intrastate natural gas pipeline safety as PHMSA's state partner, while PHMSA regulates interstate gas and hazardous liquid pipelines directly. Girth welds on new lines usually follow API 1104.

Do MIOSHA process safety rules require inspection records?

Yes. MIOSHA General Industry Part 91 adopts the federal PSM standard, which requires inspection and testing of covered equipment to recognised good engineering practice and documentation of each inspection. Our reports are structured to support that record.

Do you work in the Upper Peninsula?

Yes, by arrangement. Because of distances and seasonal access, we plan Upper Peninsula and northern Michigan work as campaigns covering several sites, such as compressor stations, mills or mine equipment, per mobilisation.

Do you offer RBI or fitness-for-service studies?

No. Atlantis does not sell API 580/581 risk-based inspection or API 579 fitness-for-service assessments. We provide the inspection data those programmes rely on.
