The comparatively new technology of computed radiography (CR) for NDT imaging has a number of advantages over traditional film-based radiography, including reduced exposure times and greater dynamic range. In addition, it does not require facilities

With the use of probabilistic and risk-based methods by industry it is often necessary to estimate and input values for the reliability of inspection methods typically in terms of probability of detection (POD). In many cases this has been based on e

In recent years there has been increased use of POD modelling to complement, and as an alternative to, probability ofdetection (POD) trials. A number of such models have been developed in ESR Technology's National NDT Centre (NNDTC) in the UK, at Iow

Within the oil and gas industry, there is increasing use of computed radiography (CR) for the in-service inspection of pipes for wall loss flaws such as corrosion and erosion. Within the HOIS joint industry programme, a major project is underway to d

In ultrasonic NDT, the 'corner trap'mechanism is a common means of detecting planar cracks which break the back-wall surface of the component. The mechanism is most efficient when the crack is normal or near-normal to the back wall, so that a specula

In the oil and gas and other process industries, there is an increasing need for the inspection of sections of pipes and vessels rendered inaccessible by components such as supports, clamps and saddles. Current ultrasonic techniques used for this in-

Over the years British Energy, in collaboration with British Nuclear Group, has developed an extensive suite of computer codes for modelling the ultrasonic inspection of smooth and rough planar defects in ferritic steel components. The models are use

The reliability of NDT inspection has traditionally been determined by experimental trials; for example PISC I-III, NORDTEST and RACH. Such trials provide practical measures of the capability of inspection equipment. However, they can be expensive, m
