Products & Services
Non-destructive Examinations

Our non-destructive testing laboratory is carrying out Your examinations and inspections of welded structures, forgings, casts and rolled products. Beginning with: ferrite content, hardness, chemical composition or thickness measurements through traditional non-destructive tests and high-end modern NDT methods described in a separate bookmark. Our journey has begun in the shipyard industry: classical and specialized floating vessels as well as rigs and mining units, for the time being, we’re involved in a series of projects in the scope of energy, mining, transport, marine and even food industry. We serve as an aid beyond what’s necessary. Our main fields of interest:

  • Wide range of non-destructive testing e.g. welds, forgings, casts
  • Structural object verification about specified rules
  • Welded construction audits
  • Solving welding process issues
  • Verification of other NDT companies

With which industries do we co-operate with?

For the time being, we carry out inspections for industries such as: offshore, petrochemical, power production and construction on components such as pressure storage and carrier tanks, pipelines, both chemical and petrochemical reactors including appliances, transfer pipelines, underwater carrier and processing systems. Years of experience and our involvement in a series of multi-stage projects increase the reliability of decisions taken by our inspectors and eliminate human error reducing unnecessary financial costs due to needless repairs.

Advanced Non-Destructive Testing

Advanced non-destructive methods create possibilities that are out of the range of classical NDT techniques. Applied methods allow for obtaining complete, more realistic information about the technical condition of the object in question with a simultaneous electronic image record. A new possibilities have emerged:

  • Examination of pipes and welds with isolation in place (intact).
  • Substitution of classical radiography using advanced ultrasonic examinations including data collection: TOFD and Phased Array.
  • Repeatable tests can be, in some cases, carried out up to 10x faster, without any significant influence on the manufacturing process – concerns mostly, but not only, mechanized ultrasonic inspections with data records.
  • What was earlier impossible to inspect can now be thoroughly verified with its proper state and condition determined – e.g. welds in configurations unfeasible for classical examination.
  • UTPA ultrasonic testing of welded joints for thicknesses under 8mm can be carried out without scaffolding. The scanner, with its electric drive and camera, can get into places out of sight of the inspector.
  • UTPA axle and shaft ultrasonic testing with scanners enables precise, repeatable scanning of objects with recording. The recording makes it possible, for example, to monitor non-conformities or to evaluate elsewhere in the world.
  • Investigations with UTPA corrosion mapping scanners. The shape of the scanner and its minimal size allow scanning of elbows, and fittings despite limited access with high efficiency which translates into corrosion diagnostic time.
  • Testing with RTD radiographic scanners. The purpose of the survey can be to inspect welded joints or to map corrosion on piping systems, including those with insulation. The scanner's drive minimises costs associated with scaffolding or mountaineering access.

What do You gain when choosing advanced examination methods in NAVITEST?

  • Complete and accepted methods authorized by surveillance societies, standardized in detail. We possess recognition for utilized examination techniques.
  • Serial tests of repeatable elements don’t influence the production process or their impact is lowered to a minimum.
  • Lack of radiation-oriented problems when substitution of radiography with ultrasonic methods takes place. Inspection societies allow for such a shift which allows our clients’ to have measurable benefits.
  • Easy, client-friendly data for corrosion mapping allows for conscientious decision-making based on acquired data.
  • No necessity for insulation disassembly when corrosion mapping is involved. Once an insulation part is dismantled it is problematic to be returned to its previous state. Money and time-saving.
  • The availability of monitoring machines in service without them being stopped allows for confirmation of their proper condition and planning of probable overhaul actions in advance.

All our utilized methods are thoroughly described in international and European standards and are accepted by approved inspection entities such as UDT, DNV, and others. What was previously impossible now becomes a reality.

Corrosion Mapping

Corrosion mapping is a technique that maps the spatial structure of a material and identifies differences in thickness caused by corrosion. Corrosion is a deterioration of the metal material caused by chemical (or electrochemical) factors. 

There are several types of corrosion:

  • evenly distributed, which spreads evenly across the entire surface
  • unevenly distributed (e.g. pitting, spot), characterized by the presence of local small areas with large cavities (pitting)
  • intercrystalline, which extends along the grain boundaries of metal

We offer our customers ultrasound and digital radiography techniques for corrosion mapping

UT techniques use scanning with semiautomatic or manual scanners with encoder. Scanning involves providing adequate access, including removing the insulation if it exists. Mapping corrosion with digital radiography does not require the removal of the isolation and shutdown of the installation. This method allows for the creation of a precise corrosion map (cavity in the material) of the examined area.

Corrosion mapping is often used in the oil and gas industry for testing pipelines, pressure vessels, storage tanks and reactors. The results of corrosion mapping are characterized by high repeatability; Their advantage is the ability to track the growth of discontinuity or corrosion, both for the entire surface, as well as individual pitting, by comparing the location and the discontinuity on two scans of the same region at different times.
