NDT Practice in Akron: A Simulator for Boiler, Power and Polymer Valley Inspection

Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and Akron’s industrial story makes it a natural fit. Practical NDT is an immersive, 3D, game-like skills-practice platform: log in from a browser or the app, enter a realistic virtual workplace, and carry out genuine inspection jobs on realistic equipment, from calibrating a UT flaw detector on a reference block to running an internal rotary probe through a boiler tube. Every attempt is scored instantly so you know exactly what you got right and what you missed. It serves every level, from new trainees to working Level IIIs.

Akron is best known as the Rubber City, and it remains home to the headquarters of a major tire maker and the centre of what the region calls Polymer Valley, a cluster of hundreds of polymer-related companies anchored by research at the University of Akron. Less widely known outside the trade is how central the Akron area is to steam and power. Babcock & Wilcox, one of the oldest names in boiler manufacturing, has built boilers in neighbouring Barberton since 1906 and moved its corporate headquarters to Akron at the end of 2019. FirstEnergy, one of the largest electric utilities in the eastern United States, is also headquartered in the city. Boilers, pressure parts, power generation and process plants that run on steam: that is the inspection core this page is built around.

Why Hands-On NDT Practice Matters in Akron’s Boiler and Power Sector

Boiler and power inspection is dominated by tubes. Waterwall, superheater, reheater and economiser tubes fail by thinning, by pitting, by fatigue cracking at attachments, by overheating and by a long list of water-side and fire-side damage mechanisms. When a unit comes down for an outage, crews have a short window to measure wall thickness, map corrosion, examine welds on replaced sections and verify that alloy tubes are the right grade. Heat recovery steam generators and industrial package boilers add their own tube and header inspection needs, and the exchangers in process plants share the same families of damage.

These are skills that decay between outages. Tube inspection is repetitive but subtle: a technician running IRIS has to keep the probe centred, the water column stable and the rotation consistent, then read the B-scan and C-scan to tell pitting from general thinning from a fretting mark. UT thickness on a boiler wall looks simple until scale, curvature and coupling conspire to produce a false reading. Welds on replaced tube sections need radiography or phased array, often in awkward access. A crew that last did this work a season ago will be slower and less reliable in the first days of the next outage than it was at the end of the last one.

Access to real practice material is limited. Boiler tube samples with known damage exist in some labs, but not in the variety needed to build real pattern recognition, and outage sites are no place to learn. Safety matters too: confined spaces, heat, height and radiography exposures on busy outage floors all add risk. Moving the learning part of the job into a simulator is sensible for everyone, leaving real, qualified work for the real equipment.

The Practical NDT Environments That Fit Akron

Practical NDT has five workplace environments. For Akron’s power and steam base, the Oil & Gas Site environment is the most relevant. Although it is set in a process plant, its 73 jobs cover precisely the families of work boiler and power crews perform: weld examination, corrosion mapping, tube inspection with IRIS, screening practice and alloy verification with PMI. The damage mechanisms and the tube geometry transfer directly to boiler, HRSG and exchanger work.

The Welding Workshop environment, with 52 jobs on weld coupons and fabrication joints, suits the pressure-part fabricators, repair contractors and boilermaker-support crews across Summit and Stark counties. It is where inspectors rehearse examination of butt welds, fillet welds and attachment welds before they meet them on a real header or pipe spool. The NDT Lab environment, with 52 bench jobs on specimens and reference blocks, anchors the fundamentals: calibration, probe selection, velocity and zero offset, and the logic of reference reflectors.

The Storage Tank environment is relevant to process plants in Polymer Valley and to fuel and chemical storage across northeast Ohio, with UT shell surveys and MFL floor screening. The Aircraft Hangar, with 54 jobs, is less central to Akron today, though the city has a long lighter-than-air heritage: the Goodyear Airdock, completed in 1929, was the largest building in the world without interior supports.

Methods You Can Practice: IRIS, PMI, Ultrasonic Testing Simulator and Phased Array Simulator

Practical NDT covers twelve methods, and several of them line up closely with Akron’s work. IRIS internal rotary UT for heat-exchanger and boiler tubes is the most important: trainees practise probe centring, water supply, rotation and pull speed, then interpret the resulting images to size wall loss and distinguish real pits from artefacts. PMI practice covers alloy verification, which matters any time chrome-moly or stainless tubes, headers or fittings are installed and the owner must prove the grade. LRUT guided-wave screening rounds out the specialist group for long pipe runs such as steam and feedwater lines on racks.

The volumetric group is UT contact, PAUT, TOFD and RT. As an ultrasonic testing simulator, the platform takes a learner through thickness gauging and angle-beam weld inspection with realistic calibration steps. As a phased array simulator, it covers focal laws, sectorial scans and interpretation of weld indications, useful for tube-to-header welds and thicker piping. TOFD adds diffraction-based sizing, and RT practice lets people rehearse exposure geometry and image interpretation for tube welds without any real source.

The surface methods, PT, MT and VT, remain the daily bread of any outage: magnetic particle on attachments and supports, penetrant on stainless components and visual inspection of tube surfaces for erosion, bulging and discoloration. The electromagnetic methods are ET, for surface cracks and non-ferrous tube screening, and MFL, practised on tank floors in the Storage Tank environment.

Built for Every Skill Level

A new trainee works through guided fundamentals across 33 guided lessons, each one breaking a task into clear steps with instant scored feedback. A new hire joining an Akron inspection contractor can arrive at their first outage already familiar with how an IRIS inspection or a UT thickness survey should flow.

A working technician uses the platform for rare-defect refreshers between assignments. Someone who has spent months on structural MT can revisit tube pitting maps before a boiler outage; someone who usually does PAUT on large welds can practise the smaller, thinner tube welds that behave differently. The ability to meet unusual damage in simulation, repeatedly, is hard to get any other way.

A Level III or team lead can build and assign scenario sets, benchmark crews objectively and find coverage gaps. Ahead of an outage, a lead might assign identical IRIS, PMI and UT thickness jobs to the whole crew and use the scores to decide who takes which scope. The scenario library was designed by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT, who leads Atlantis training, so the tasks follow real inspection practice.

How It Complements Formal ASNT Training and NDT Practical Exam Preparation

Practical NDT is a practice and readiness tool, full stop. It is not a certification and it does not replace the practical examination on real specimens required by an employer’s written practice under ASNT SNT-TC-1A. The real practical uses real specimens and real equipment and is administered by your employer according to its written practice. That does not change.

What Practical NDT offers is a better route to NDT practical exam preparation. Candidates can rehearse the full sequence of each method many times, get immediate feedback, and correct habits before they reach the real exam. It complements the classroom and hands-on training available through Atlantis NDT training and gives instructors a view of weak points in advance, so real bench time is spent where it matters.

Power generation and pressure equipment owners in Ohio may also impose their own qualification requirements, and code work on boilers and pressure vessels is governed by the applicable construction and inspection codes and by the state’s boiler inspection rules. Those are the employer’s and owner’s responsibility. Practical NDT’s job is to help technicians be ready for whatever real examinations they will face.

Akron’s Industrial Map: Barberton, Polymer Valley and the Utility Grid

South of downtown, Barberton has been synonymous with boiler making for well over a century, and the ecosystem around it includes machine shops, pressure-part fabricators, heat-treatment providers and inspection contractors who travel to power and industrial sites across the country. Many Akron-area NDT technicians spend much of the year on the road, working outages far from home. For them, a browser-based NDT simulator they can use from a hotel room is a practical way to stay sharp.

In the city and its suburbs, Polymer Valley brings a different flavour of industrial work. Tire and rubber production relies on steam, curing presses, pressure vessels, heat exchangers and extensive plant piping, all of which need periodic inspection. Chemical and compounding plants in the region add storage tanks, reactors and process lines. The polymers themselves are not what gets inspected with these methods, but the plant equipment that makes them is, and it looks a lot like the process equipment in the Oil & Gas Site and Storage Tank environments.

Across the wider region, FirstEnergy’s transmission and distribution network and the generation assets serving northeast Ohio add structural, weld and component inspection work, and the Utica shale play to the east brings pipeline and midstream construction. Industrial radiography in Ohio is regulated by the Ohio Department of Health under the state’s Agreement State programme with the NRC, so real exposures are carefully controlled; practising interpretation in software is a sensible complement. For companies looking at NDT training online in Ohio, Practical NDT adds repetition without adding risk.

An Example Outage Readiness Plan

Here is one way an Akron-based inspection contractor might use the platform before a boiler or HRSG outage, offered as an example workflow rather than a claim of results. The Level III reviews the owner’s scope and selects matching jobs: IRIS for tube-side inspection, UT thickness for waterwall grids, PMI for any alloy replacements, and PAUT or RT interpretation for replaced tube welds. Each technician gets a short scenario set matched to the scope they are likely to cover.

Over the week before mobilisation, technicians complete their sets in short sessions. The Level III reviews scores, spots who is consistently accurate on thickness mapping, who struggles with IRIS interpretation, and who is weak on alloy verification. Weaker areas get targeted repetition, and people are allocated to scope based on demonstrated readiness. After the outage, the crew can repeat the scenarios, and the lead can add new ones based on anything unusual found in the unit, building a continuing record of crew capability that survives staff turnover.

Bringing Practical NDT to Your Akron Team

Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and the best way to judge it is to see the jobs that match your work. For boiler and power crews that usually means the Oil & Gas Site with IRIS and PMI plus the Welding Workshop; for plant maintenance teams in Polymer Valley it often means the Storage Tank and NDT Lab. Request a Practical NDT demo in Akron.

Most rollouts start with a pilot group, then expand once a Level III has built scenario sets for the full crew. Access is via browser or app, so there is nothing to install and nothing to ship. Pricing is quote on request, tailored to your team size and use; ask for a tailored quote.

Frequently Asked Questions

Does Practical NDT replace the practical certification exam?

No. Practical NDT is a skills-practice and readiness tool. Certification under ASNT SNT-TC-1A follows your employer’s written practice, which requires a practical examination on real specimens with real equipment. The simulator prepares you; it does not certify you.

What experience level is it for?

Every level. New trainees use 33 guided lessons, working technicians use rare-defect refreshers between assignments, and Level IIIs or team leads build and assign scenario sets to benchmark crews objectively.

Can boiler and HRSG crews practise tube inspection?

Yes. IRIS internal rotary UT for heat-exchanger and boiler tubes is one of the twelve methods, practised in the Oil & Gas Site environment, alongside UT thickness, PMI alloy verification and weld inspection with PAUT, TOFD and RT.

Is it useful for tire and polymer plant maintenance teams?

It is useful for the plant equipment those teams inspect: vessels, piping, exchangers and tanks. The Storage Tank and Oil & Gas Site environments cover UT thickness, MFL floor screening, weld and corrosion work that applies to process plant equipment generally.

Can travelling outage technicians use it on the road?

Yes. It runs in a browser or the app, so technicians can practise from wherever they are staying. Contact us to arrange access for your crew.
