In practice a simple NDT method that is most used on site for in-service inspection to locate wall loss due to corrosion / erosion etc. For UTT to be effective requires a very careful attention to detail. This has been recently recognised by National Standards where previously it was considered a ‘UT thickness measurement’ isContinue reading “Ultrasonic Thickness Testing (UTT)”

What do I use as my confirmation technique when my Advanced NDT inspection finds a problem?
There have been many recent instances where an innovative new ANDT technique is utilised to inspect a component due to the part having difficult or no access to more conventional NDT techniques. Examples of this technology could be search techniques that can ‘point you in the right direction’ by quickly screening large areas of aContinue reading “What do I use as my confirmation technique when my Advanced NDT inspection finds a problem?”
Tangential Radiography for wall loss – getting it right
When carrying out tangential radiography to BS EN 16407 (Radiographic Inspection of corrosion deposits in pipes by X and Gamma Rays) an example of a typical set up is shown below where the pipe wall at certain positions can be imaged. With this technique it is important to ensure you get the set up rightContinue reading “Tangential Radiography for wall loss – getting it right”
