Ultrasonic Thickness Measurement for Better Decisions
Visual inspection shows the surface. UTT adds measured evidence about the material beneath it.
Ultrasonic Thickness Testing (UTT) uses a probe placed on one accessible side of a component to measure the distance to its back wall. This non-destructive thickness testing method allows remaining material thickness to be assessed without cutting or drilling.
Britteco provides targeted tank thickness testing, pipe wall thickness testing and detailed corrosion and wall-thickness surveys for commercial fuel tanks, storage vessels, pipework and associated steelwork. Measurements can help identify patterns of corrosion, pitting and localised wall thinning, supporting maintenance planning and decisions about further investigation.
Point readings are not whole-asset coverage. We agree locations and measurement density around the expected damage mechanism. Selected-point surveys, defined grids and focused follow-up readings answer different inspection questions.
What UTT can assess
Focused Measurements. Practical Insight.
The ultrasonic thickness survey is matched to the asset, access, surface condition and the decision the results need to support.
Corrosion & Thinning
Identify reduced readings and broader thickness trends consistent with material loss. A reading does not by itself establish whether loss is internal or external.
Pitting Investigation
Take focused readings around suspect areas to help characterise localised loss of wall thickness.
Tank Thickness Testing
Apply planned measurement grids or selected-point testing to accessible fuel tank shell, roof and associated areas.
Pipe Wall Testing
Measure accessible pipe sections, bends and selected locations where corrosion or service history warrants attention.
Point or Grid Surveys
Use a proportionate selected-point scope or a defined measurement grid, with readings logged for traceability.
Cygnus 1 Ex capability
Built for Hazardous Areas
Britteco uses Cygnus 1 Ex ultrasonic thickness equipment certified to ATEX, IECEx and UKEx requirements. Its intrinsically safe design supports suitable inspection work in hazardous gas Zones 0, 1 and 2, including fuel-storage and industrial environments, subject to site controls and the agreed method.

How the service works
From Scope to Report
A defined inspection scope keeps the survey proportionate and makes the resulting data easier to interpret.
Scope Review
We review the asset type, product history, access, hazardous-area classification and required outcome.
Site Preparation
Inspection points, permits, RAMS, access and surface preparation requirements are agreed.
UTT Survey
Readings are taken and logged at the agreed locations, with focused checks where results warrant them.
Results & Report
We organise the recorded measurements and issue the agreed report or measurement certificate for your records.
What you receive
Useful, Traceable Inspection Data
The reporting level is matched to the selected package and survey scope. For detailed work, readings can be associated with a measurement plan or grid so that lower-thickness areas and patterns are easier to review.
A-scan and B-scan functions support the inspection and review process. Data logging enables recorded measurements to be transferred into the reporting workflow.
Scope note: this service is ultrasonic thickness measurement. It is not advertised as weld-flaw detection. Any requirement for a different NDT method or engineering fitness-for-service assessment should be identified separately.

Common questions
Ultrasonic Thickness Testing FAQs
Answers are general; the correct inspection scope depends on the asset, material, condition and site controls.
UTT is a non-destructive method that uses sound waves to measure material thickness from one accessible side. It is commonly used to assess remaining wall thickness and investigate corrosion, pitting or localised thinning.
Suitable Cygnus measurement modes and probes can support measurements through coatings in appropriate conditions. The coating, surface condition, material and required accuracy are reviewed before the method is confirmed; local preparation may still be needed.
Britteco's Cygnus 1 Ex equipment is ATEX, IECEx and UKEx certified and designed for suitable use in hazardous gas Zones 0, 1 and 2. Work remains subject to the site's hazardous-area controls, permits and agreed method.
No claim is made that this thickness-measurement service detects weld flaws. Weld-flaw examination is a separate NDT discipline and may require different equipment, procedures and qualified personnel.
Please provide the site postcode, asset type and size, number of assets, product stored, access details, hazardous-area information, photographs and the purpose of the survey. Existing drawings or previous thickness readings are also helpful.
Basic surveys start from £1,100. Detailed surveys are typically £1,200–£1,600, while complex or full-day work is typically £1,600–£2,000+. The final quotation depends on scope, travel, access, preparation and reporting requirements.
The accessible surface is assessed and prepared where necessary, couplant is applied, and a suitable probe is placed at each agreed location. The gauge is configured for the material and probe, readings are checked for a stable response, then recorded against the inspection plan for reporting.
Yes, stainless steel and other ultrasonically conductive materials may be measurable when a suitable probe, sound velocity and calibration are used. Feasibility and measurement range depend on the specific material, geometry, surface condition and required result.
There is no reliable universal number. The measurement density depends on asset geometry, nominal thickness, likely corrosion mechanism, previous findings and the survey objective. A selected-point check answers a different question from a defined grid or detailed corrosion map.
The Cygnus 1 Ex manufacturer specification states ±0.1 mm or 0.1% of the measured thickness, whichever is greater. Field confidence also depends on calibration, probe, material, geometry, temperature, coating, surface condition and echo quality.
There is no single minimum for every setup. The Cygnus 1 Ex family specification covers approximately 0.8–250 mm in steel depending on the selected probe and configuration. Britteco's quoted S5A-Ex and T5B-Ex probes have their own narrower ranges, so the applicable range is confirmed against the job scope.
