Ultrasonic Thickness Testing (UTT) in Findlay, OH

UTT for Findlay and Northwest Ohio Industry

Northwest Ohio’s refining, processing, pipeline, and manufacturing operations rely on pressure-retaining equipment that must remain within safe operating limits. Corrosion and erosion can gradually thin pipe walls, tank shells, vessel components, and other metal assets—often without visible signs of damage. Ultrasonic Thickness Testing (UTT) provides measured thickness data to help identify that loss before it becomes a leak, unplanned outage, or integrity concern.

From Findlay, TechCorr serves facilities across Ohio’s industrial network, including the Toledo–Findlay–Lima corridor and connected pipeline routes. That regional reach helps plant and integrity teams arrange inspections around maintenance windows, assess concerns at targeted locations, and plan follow-up work across operating sites. UTT readings can support condition monitoring, remaining-life evaluations, repair decisions, and prioritization of replacement—always interpreted in the context of the asset, its service, and applicable engineering requirements.

How Ultrasonic Thickness Testing Works

UTT is a non-destructive testing and inspection method based on the transmission of high-frequency sound through a material. A qualified technician applies an ultrasonic couplant and places a probe on an accessible surface. The instrument measures the time required for sound to travel through the material and reflect from the opposite wall, then calculates thickness using the material’s acoustic properties.

Because the measurement is taken from one side, UTT can often be performed without removing the component from service or cutting a sample. The method is commonly used to assess accessible points on piping, pressure vessels, and storage tanks. Surface condition, coatings, geometry, temperature, material characteristics, and probe access can affect results; inspection planning and technique selection account for those conditions. Where a single reading is not representative, a defined grid, repeat measurements, or additional examination may be appropriate.

UTT data is most useful when it is traceable and comparable. TechCorr can collect readings at identified locations and document results for evaluation against nominal or previous measurements. Comparing like-for-like locations over time helps teams identify trends and estimate corrosion rates when suitable historical data is available. Thickness measurements contribute to remaining-life and fitness-for-service decisions, but they do not replace engineering assessment or other required inspection methods.

What TechCorr’s Findlay Team Delivers

TechCorr’s Findlay office brings conventional NDE capability together with regional experience in storage tank inspection and pipeline NDE. For UTT scopes, the team can help define examination locations, coordinate access and timing with site personnel, perform thickness measurements, and provide documented results for integrity review. The scope is tailored to the asset and inspection objective rather than treated as a one-size-fits-all survey.

Typical applications include corrosion monitoring on process and utility piping, thickness checks on vessel shells and heads, and wall-thickness surveys on accessible tank components. UTT can also help investigate suspected localized loss or establish a baseline for future monitoring. When findings indicate that broader examination may be needed, TechCorr can coordinate applicable conventional NDE support and discuss the next steps with the client’s inspection or engineering team.

Clear records matter as much as field measurements. Reporting can identify examination locations and measured values so the results can be reviewed alongside drawings, prior inspection data, operating history, and repair records. This supports practical asset integrity planning: teams can focus on areas of concern, schedule repairs with greater confidence, and maintain a useful record for future inspections.

Standards, Qualifications, and Inspection Planning

Inspection requirements depend on the asset type, service, jurisdiction, and owner-user program. API 510 provides inspection guidance for pressure vessels, API 570 addresses in-service piping inspection, and API 653 covers aboveground storage tank inspection. These standards establish broader inspection frameworks; the applicable code, inspection plan, and authorized inspector determine how UTT results are used and what follow-up is required.

Personnel qualification and written procedures are also important. TechCorr can align work with applicable ASNT personnel qualification practices and client requirements, including relevant employer procedures and certification expectations. Where corrosion control, materials selection, or degradation mechanisms are part of the assessment, NACE International—now AMPP—guidance may inform the broader integrity program. ISO quality and inspection requirements can apply where specified by the contract or facility procedures. Standards and certifications are not interchangeable: the governing code, scope, and site rules should be confirmed before work begins.
