Nondestructive testing

Execution and interpretation of UT, MT, PT, RT and VT testing, in accordance with the procedures and requirements applicable to each project. Tests are interpreted by an ASNT-certified inspector and are carried out on our own projects or on third-party work.

Scope

What it covers

Scope is adjusted to the requirements of each project. These are the activities we normally execute within this service.

  • Ultrasonic testing (UT)

    Detection of internal discontinuities in welds and measurement of remaining wall thickness.

  • Magnetic particle testing (MT)

    Detection of surface and near-surface discontinuities in ferromagnetic materials.

  • Liquid penetrant testing (PT)

    Detection of surface-breaking discontinuities in any non-porous material.

  • Radiography (RT) and visual testing (VT)

    Radiographic records of joints, plus dimensional and weld-profile visual inspection.

Frequently asked questions

Can interpretation be contracted without carrying out the testing?

Yes. Interpretation and the issuing of the signed report can be delivered remotely, over records taken by another team.

Which test applies to each project?

It depends on the applicable code, the material and the joint type. It is defined once the project's technical specification is reviewed.

Who signs the results?

An ASNT-certified inspector. That signature substantiates the test as a document that can be presented to the client or to the body auditing the project.

What information is required to quote testing?

Number and type of joints, material and thickness, the applicable code and the project location.

What is the delivery schedule for the report?

Turnaround is agreed together with the scope: per-joint reports are delivered as testing progresses, and the consolidated report at close-out.
