Industrial Radiography is a Non Destructive Testing method that involves passing a beam of radiation from an object to a radiographic film. This method enables discontinuities present within the object to be observed on the radiographic film. The following related techniques are readily available from SCI:


SCI has the following equipment for industrial radiography:

  • Camaras for Ir 192 sources and SE75 sources.
  • Fixed scan equipment for use in a bunker with Co60 sources.
  • Portable X-ray equipment up to 360 kV for use in a bunker and on site.
  • X-ray equipment up to 450 Kv constant potential for use in a bunker.

At most of its premises SCI has bunkers for X-ray and there is always the possibility of installing modular bunkers on a customer’s own site.

Since late 2009, SCI has had a 6 MeV linear accelerator at its facilities in Beasain (Guipúzcoa), exclusively for radiographic inspection of large components, SCI is the the leading Spanish company specialising in radiographing steel thicknesses of up to 300 mm in a bunker and has earned a global reputation as demand for such services in the metallurgical sector continues to grow.

Digital Radiography is an alternative to conventional radiography in which the X-ray film is replaced by a sensor which provides a digital radiographic image.

As with automatic ultrasound the advantages of digital radiography have been known for some time. These advantages including not only immediate results but the absence of using chemicals, ease of recording and storing on file, the ease of archiving film, shorter exposure times, radiographic quality similar to conventional radiography, a greater ease and immediacy in the analysis of results, and more.

There are two areas in which the use of this technique is particularly useful:

  • X-raying components in a large series.
  • Evaluation of the corrosion beneath pipe-lagging in petrochemical plants, air conditioning systems, etc.


Complementing the use of conventional radiography, digital radiography is an innovation in the conservation of radiographic film and a solution to archiving problems. The digitization of radiographic scanner plates results in a very high resolution and a quality of scanned images similar to those of conventional film.

Digital images obtained can be treated and used in a similar way to conventional radiographs.


With the introduction of crawler type computers in Spain, automated radiographic gas and pipeline inspection has been greatly improved, allowing the examination of a large number of welds in less time and to a much greater accuracy.

SCI designs and manufactures its own crawler equipment, suitable for diameters from 3″ to 60″. SCI has been a market leader in Spain for the inspection of oil and gas pipelines while under construction and has now greatly extended these service worldwide.
