NDT INSPECTION SERVICES

What Non-Destructive Testing Is

Non-destructive testing covers a group of techniques used to assess the condition of materials, welds and equipment without damaging them or taking them out of use permanently. The asset is examined, measured and returned to service.

That matters because the alternative is either destructive testing, which consumes the item being tested, or waiting for a failure to reveal the problem. NDT lets an owner find corrosion, cracking and material defects while there is still time to plan a response, and it produces the evidence that regulators, insurers and clients ask for.

No single method answers every question. Ultrasonics measures thickness and finds flaws within a material. Magnetic particle and penetrant testing find defects breaking the surface. Eddy current handles tubing and coatings. Most real inspection scopes combine several.

NDT Methods

The core non-destructive testing techniques. Which one applies depends on the material, the type of flaw you are looking for and where it sits.

Asset and Equipment Inspection

Inspection programmes built around a type of asset, drawing on whichever NDT methods the job requires.

Welding and Radiography Services

Supporting services covering weld qualification and the radiography function itself.

Choosing an NDT Provider

The techniques are broadly standardised, so the difference between providers usually comes down to three things.

Qualification of the people doing the work. NDT output requires interpretation, and a scan is only as good as the person reading it. Ask what certification the technicians hold and whether it covers the specific method being applied, since a general ultrasonic qualification does not automatically cover phased array.

What the report actually contains. Readings alone leave you no further forward. A useful report states the standards applied, records where measurements were taken so the next inspection can be compared against them, sets out the findings against acceptance criteria, and says what happens next.

Whether the scope is right. A provider who applies one method to every problem will miss things. The scope should be built from what you need to know about the asset, not from the equipment that happens to be available.

Accreditation and Qualifications

APEC Inspection is accredited by NATA to ISO/IEC 17025:2017, the international standard for the competence of testing and calibration laboratories. Accreditation covers the technical competence of the methods, the equipment and the people, and it is assessed by NATA rather than self-declared.

Our non-destructive testing is carried out by technicians certified to ISO 9712 through AINDT, the Australian Institute for Non-Destructive Testing. Certification is method-specific and graded by level, which is what allows an inspector to interpret results and sign a report rather than simply operate equipment.

Between them, those two cover the questions most clients and auditors ask: is the organisation competent to perform the test, and is the individual qualified to interpret it.

Where We Work

APEC is based in Newcastle and works throughout the Hunter and New South Wales, mobilising inspectors to sites across Australia. Work is commonly scheduled around planned shutdowns and outages, so bringing us in early makes the sequencing easier, particularly where equipment has to be taken out of service, emptied or cleaned before inspection.

If you have an inspection requirement and are not sure which methods apply, that is a normal starting point. Tell us about the asset and what you need to establish, and we will scope it.
