NEWS – Nordic NDT AB is now also accredited for digital radiography (DDA).

With the Digital Detector Array for digital X-ray of your objects during operation and at the same time reveal any material defects or material thinning and also foreign objects in your pipe system that can cause poor flow. The method can be used on various materials such as steel and other metals, cast parts, plastic and composite.The digital panel requires significantly less radiation compared to analog X-ray radiography.

The method is also much more environmentally friendly than traditional X-ray radiography.

Example 1 Thickness measurement on insulated pipes during operation

The Digital Detector Array (DDA) is an electronic device that converts ionizing radiation into analog signals, which are then digitized and transferred to a computer and displayed in the form of a high-resolution image.

By selecting various parameters and calibration, the DDA can produce an image that is often better than what traditional X-ray film generates. The digital image can be regulated and adjusted with advanced software for an accurate and clear analysis of the image.

NOVO DR portable digital systems provide high-quality images within seconds to detect material defects, cracks, weld defects, etc. The system is easy to use, carry and control and provides unmatched productivity for intensive X-ray assignments in the field or in the laboratory. Information is stored digitally and can be easily accessed, shared, analyzed and archived for future reference.

The X-ray image is analyzed and evaluated and the result is sent to a computer. Using the advanced software, the technician evaluates the X-ray image, which then measures and analyzes various defects and conditions. We enhance and highlight different parts of the tested object to examine any defects or deviations in more detail.The DDA panels we use meet the requirements according to SS-EN ISO 17636-2 class B for weld testing.

With Digital Detector Array it is possible to perform X-rays through insulation and during operation.

You no longer need to stop the plant to find out the status of the plant.

Through digital X-rays you can detect defects, cracks, corrosion, erosion and material thinning at an early stage. The method is also used to advantage to detect flow reduction or stoppage due to e.g. deposits, solidified media or debris in, above all, pipelines.

With DDA you can avoid costly downtime, repairs and system replacements.

Examples of applications:

Welded structures

Pipelines in both steel and plastic

Inspection of sprinkler systems during operation

Insulated pipelines during operation

Metals of various types, plastics and composite materials

Cast parts

Valves and pressure vessels
