NDT techniques

Radiographic testing

Radiographic testing, x-ray inspection

Radiography is a versatile tool for the inspection of a wide variety of items.

James Fisher NDT offers both film and digital radiography and has 8 fully equipped bays for "shop" inspections and equipment for "field" radiography using X-ray for applications requiring high definition or gamma ray techniques where high energy is required, e.g. screening thick wall material.

Gamma radiography is performed with iridium sources or using the low emission saferad system which provides high sensitivity at reduced risk and is more "site friendly" in terms of permits and work area restrictions.

Applications include the "as built" quality control and in-service condition assessment of welds, forgings and castings.

Using 'profile' radiography it is possible to perform "double wall/single image" assessment of through wall condition to establish the presence and extent of metal loss through corrosion or internal lining breakdown and fouling.
