NDT Inspection Services in Indiana

Short answer: Atlantis NDT provides NDT inspection services across Indiana with ASNT-certified technicians working under ASNT Level III oversight: UT thickness surveys, PAUT, TOFD, corrosion mapping, MT, PT, VT and ET, radiography through radiography crews licensed in Indiana, and NDE support for API 510, API 570 and API 653 programmes. We mobilise crews to your site, agree the schedule during scoping and issue Level III-reviewed digital reports traceable to the governing code.

Indiana makes more steel than any other state, runs the largest refinery in the Midwest on the Lake Michigan shore, and builds engines, vehicles, pharmaceuticals and plastics in plants spread from Fort Wayne to Mount Vernon. Its inspection market is therefore shaped less by oilfields and more by mills, heavy manufacturing and the Calumet Region's industrial shoreline. This page explains where Indiana's inspection work is, which NDT methods and codes apply, which Indiana regulators sit behind it (including the change to radioactive-materials licensing that took effect at the start of October 2026), and how to scope a job with us.

Where inspection work is in Indiana

Direct answer: Indiana inspection demand is heaviest in the Calumet Region of Lake County and Porter County (Whiting, East Chicago, Gary, Hammond, Burns Harbor), followed by central Indiana's engine, pharmaceutical and construction cluster around Indianapolis and Columbus, the southwest river corridor of Evansville and Mount Vernon, and the manufacturing towns of the north and northeast such as Fort Wayne, South Bend and the steel minimills.

The Calumet Region: Whiting, East Chicago, Hammond and Gary

The Whiting refinery is the largest in the Midwest, and its crude units, cokers, hydrotreaters, tank farms and docks generate a year-round inspection workload: UT thickness at piping CMLs, PAUT and TOFD on new and repaired welds, MT and PT during turnarounds, VT of vessel internals and tank surveys. Immediately east, integrated steelworks at East Chicago, Indiana Harbor and Gary, plus the Burns Harbor works in Porter County, run blast furnaces, coke batteries, hot-strip mills and enormous cranes and structures. Mill inspection is about rotating equipment shafts, crane girders and runways, boiler and power-house piping, gas mains, ladles and structural weld repairs, where UT and MT do most of the work. Hammond adds component manufacturing and corn milling. Related Atlantis pages: Whiting, Whiting refining NDT, East Chicago, Gary steel NDT and Hammond.

Porter and LaPorte counties: Burns Harbor, Portage and La Porte

The Port of Indiana at Burns Harbor handles steel, bulk and liquid cargoes on Lake Michigan, with fabrication and terminal operators around Portage. La Porte has metal fabrication and processing plants. Here inspection mixes steel-plant maintenance, terminal tank surveys and structural weld inspection on port and plant projects. See Portage and La Porte.

Central Indiana: Indianapolis, Columbus, Lebanon and Lafayette

Indianapolis builds aero engines and transmissions, Columbus is home to a major diesel-engine maker, and Lafayette and the surrounding counties assemble vehicles. In Boone County, very large pharmaceutical manufacturing construction around Lebanon has brought high-purity process piping, utilities and structural steel on a scale few Midwest sites have seen. Inspection demand here includes weld inspection on construction (stainless and carbon steel piping to ASME B31.3, structural steel to AWS D1.1), PT and ET of aerospace and engine parts, and periodic inspection of boilers, autoclaves and pressure vessels in operating plants. Indianapolis already has Atlantis pages for weld inspection, pressure vessels, piping and third-party inspection.

Southwest Indiana: Evansville, Mount Vernon and the Ohio River

Mount Vernon has an in-state refinery and a large engineering-plastics plant, Newburgh has aluminium smelting and rolling, and the Evansville area holds chemical, pharmaceutical and power plants along with Ohio River barge terminals and the Port of Indiana at Mount Vernon. Coal-fired and gas-fired generating stations in the region run boilers, high-energy piping and storage tanks. Typical inspection: refinery and chemical piping thickness, boiler tube and header checks, tank floor and shell surveys at river terminals. See Evansville consulting and Evansville steel NDT.

Northern and northeast Indiana: Fort Wayne, South Bend, Elkhart and the minimills

Fort Wayne and the surrounding counties assemble trucks and make engine and drivetrain components, and electric-arc steel minimills operate across the north-east. South Bend and Elkhart add RV, trailer and component manufacturing with high weld volumes. Inspection is mostly weld quality (VT, MT, UT) and maintenance NDE on mill and press equipment. See the South Bend practical NDT page.

Southern Indiana: Crane and the defence corridor

Naval Surface Warfare Center Crane in Martin County is one of the largest naval installations in the country by area, and its contractors and suppliers work to Navy technical requirements. Defence-related fabrication across southern Indiana can therefore call for NDT to NAVSEA-style specifications alongside ASME and AWS, which affects procedure content and certification evidence.

NDT methods we deliver in Indiana

Direct answer: we deliver UT thickness and shear-wave UT, PAUT, TOFD, corrosion mapping, RT through radiography crews licensed in Indiana, MT, PT, VT and ET. In Indiana the method mix tilts toward MT and UT on mill and heavy-manufacturing equipment, and toward thickness, PAUT and tank methods in the Whiting and Mount Vernon refining areas.

For more on individual methods in Indianapolis see ultrasonic testing, radiographic testing, magnetic particle testing and eddy current testing, and the technique pages for corrosion mapping and TOFD.

API 510, 570 and 653 inspection support in Indiana

Direct answer: for Indiana pressure vessels, piping and aboveground tanks we supply NDE crews, thickness and weld data, corrosion-rate and remaining-life calculations and written findings for your own API-certified Authorized Inspector. Atlantis does not act as inspector of record; that sign-off stays with your inspector or inspection agency.

API 510 pressure vessels. Refinery drums, reactors and exchangers at Whiting and Mount Vernon, and process vessels in chemical, plastics and pharmaceutical plants, need external, on-stream and internal inspection. We run UT thickness grids, PAUT or TOFD on welds of concern, MT or PT on nozzle welds and VT of internals, then hand over the data reduced to corrosion rates. See API 510 pressure-vessel services.

API 570 piping. We read thickness at your existing CMLs, compare against history, flag anomalies, and screen insulated lines for likely corrosion under insulation, which the lake-effect humidity and freeze-thaw cycles of northwest Indiana make a real concern. See API 570 piping services and corrosion inspection in Indianapolis.

API 653 tanks. Crude and product tanks at Whiting, terminals near Griffith and Hammond, river terminals at Mount Vernon and the many ethanol-plant tanks across rural Indiana all fall under tank integrity programmes. We provide shell UT, floor MFL with UT prove-up, weld MT or PT and settlement survey support, delivered to your API 653 inspector. See API 653 tank services and tank inspection in Indianapolis.

Pipelines. Crude trunk lines from Canada and the western states terminate around the Whiting and Griffith area, and natural gas transmission lines cross the state. We inspect construction welds and support integrity digs; see pipeline inspection services and Indianapolis pipeline inspection.

Turnarounds, mill outages and planned inspection

Direct answer: Indiana's planned inspection follows two calendars: refinery and chemical turnarounds, usually in spring or autumn, and steel-mill outages, which are scheduled around production and often run over holidays. Both are short and crowded, so inspection scope, procedures and crews must be ready before the shutdown starts.

In a mill outage, the inspection list is long and the window is measured in days: crane runways and girders, ladle and transfer-car structures, roll shafts, coupling spindles, gas-main sections and power-house piping all compete for the same few shifts. Refinery turnarounds at Whiting add thousands of inspection items and draw contractors from across the Midwest. In both cases the winning approach is to separate what can be done beforehand from what truly needs the equipment stopped. On-stream UT thickness, external VT, corrosion mapping and much of the PAUT can be done weeks ahead; the outage then focuses on internal inspection, repair welds and post-repair NDE.

Our Level III reviews the owner's specification against our procedures before mobilisation, identifies any technique needing qualification or demonstration, and sends technician certifications for your contractor approval. During the outage, data goes straight into our reporting platform so your coordinator sees results daily. Critical findings are escalated to your site contact at once. Plan your Indiana outage inspection early and you get a crew that has already read your specification.

Northwest Indiana winters are harsh on the lakefront. We plan for cold-weather couplant, instrument and battery performance, film processing limits and personnel welfare rather than discovering the problems in a January outage.

Indiana regulations that shape inspection

Direct answer: Indiana inspection sits under the boiler and pressure vessel rules of the Indiana Department of Homeland Security, state and federal radiation rules for radiography (which changed when Indiana became an NRC Agreement State on 1 October 2026), pipeline safety by the Indiana Utility Regulatory Commission and PHMSA, and Indiana OSHA (IOSHA) plus federal EPA rules for process safety and oil storage.

Boilers and pressure vessels. The Boilers and Pressure Vessels Section of the Indiana Department of Homeland Security enforces the Indiana Boiler and Pressure Vessel Rules (675 IAC 30). Regulated equipment needs an operating permit, operating-permit inspections must be performed by inspectors licensed by the Department (state, insurance or owner-user inspection agency inspectors), and inspection reports go to the Department within a set period. NDE we perform on repairs and alterations is documented so the licensed inspector and the repair organisation can rely on it.

Radiography. Indiana signed an agreement with the NRC in September 2026 and became the 41st Agreement State on 1 October 2026, with the Indiana Department of Homeland Security's Radioactive Materials Control Program taking over licensing, inspection and enforcement for most radioactive materials, including industrial radiography sources, from the NRC. Because the transition is so recent, confirm the current licensing authority with the state before any radiography job, and check how existing NRC licences are being carried over. Atlantis does not claim its own Indiana radiography licence; RT is performed by radiography crews licensed in Indiana, using our procedures and reporting format.

Pipelines. The Indiana Utility Regulatory Commission's Pipeline Safety Division oversees intrastate gas pipeline operators, while interstate gas lines and hazardous liquid lines, including the crude systems running into the Whiting area, fall under PHMSA and 49 CFR Parts 192 and 195. Construction welds are usually inspected to API 1104.

Process safety and oil storage. Indiana runs its own OSHA-approved state plan, IOSHA, under the Indiana Department of Labor, which enforces process safety management requirements equivalent to OSHA's 29 CFR 1910.119 at refineries and chemical plants. The mechanical integrity element of PSM is what makes documented, code-referenced inspection mandatory. Aboveground oil storage falls under the EPA's SPCC rule, which expects integrity testing to an industry standard such as API 653 or STI SP001.

Regulations change, and Indiana's radiation programme has just changed; check with the agency before relying on any summary. Our Level III can help map requirements to inspections; see the Indiana NDT consulting hub.

Inspection reports clients can use

Direct answer: Atlantis inspection results are captured on site in our own digital reporting platform, reviewed by a Level III and issued with the procedure, code, acceptance criteria, technician certification level and instrument calibration recorded, so an Authorized Inspector, insurer or auditor can trace each finding back to its source.

Thickness data is organised by circuit or component and CML, with prior readings for trend. Weld results reference the weld map and the acceptance standard. Mill inspection is reported by asset tag so maintenance planners can schedule repairs. Every indication carries a location, dimensions, evaluation and photo. There is no handwritten-sheet transcription step, which removes a common source of error. Read more on our NDT inspection software and reporting software pages.

The same data can go further if you want it to: owners can see results on a 3D model of a unit, tank farm or mill structure through our digital twin platform (see the Whiting example), and NDT service companies can run scheduling, certification tracking and invoicing in the Atlantis ERP. Level III-led inspection, digital report and an optional twin, from one provider.

Level III oversight on every Indiana job

Direct answer: each Atlantis inspection is run under an ASNT NDT Level III, Anoop Rayavarapu, founder of Atlantis NDT, who approves procedures, reviews results and answers for the method choices. Indiana owners get one accountable technical authority from scoping to report.

Steel producers, engine makers, pharmaceutical owners and the Whiting refinery all audit their contractors. The questions are always the same: which written practice certified the technician, which procedure applied, was it qualified or demonstrated, who reviewed the data. With a Level III involved from the start, the answers are prepared before anyone asks. The Level III also makes the technical calls: whether PAUT can replace RT on a construction package, when TOFD sizing is justified, how to cover a crane-girder weld with restricted access. Employers who want to strengthen their own programme can use our written practice development service.
