Ultrasonic rotating system for defect detection (depending of the productivity requested); two to four channels for transversal flaws; and two channels with reference for thickness measurement.

BUILDINGon the recent launch of Sonatest’s new phased array ultrasonic flaw detector, the veo 16:64 has made inroads into many of its key application markets, one of which is pipe and pipeline weld inspection. Ultrasonic phased array technology is becoming an established method for advanced NDT testing applications allowing operators to have greater control over testing parameters, enhancing defect detection, using real-time results, while increasing the speed of testing procedures and improving site health and safety. Weld inspection and crack detection are key application areas for phased array ultrasonic testing and are requirements within the industries of tube and pipe manufacture, pipeline construction and maintenance. Within these sectors, phased array is also used to test for remaining wall thickness and pipe wall corrosion. The Sonatest veo 16:64 phased array flaw detector includes features such as 3D Scanplan, TCG/ACG, fast A-Scan recording and full data capture. Two separate conventional channels provide the user CONTRÔLE Mesure Systèmes, a manufacturer of non-destructive testing equipment using eddy current and ultrasonic techniques for tube inspection, has increased its production range with the ‘ultrasonic rotating head’. The new development will allow the detection of both outside defects and internal defects. Several transducers (up to 24) are driven in rotation around the product. Some transducers are set for longitudinal defect detection, with others orientated for transversal defect detection, or dedicated to dimensional measurement. The basic construction consists of two to four channels for longitudinal flaws

high quality tubes in materials such as stainless steel or titanium, but can also be used for other applications where high quality is required. The rotating ultrasonic head can be combined with other CMS equipment, such as a rotating eddy current head or magnetising unit with coil, already installed in a strong control bench including centring devices.

The UT rotating heads are proposed in different sizes for different tube diameters, ranging from Size 1 for tube OD up to 25mm, to Size 6 for OD up to 200mm. The rotation speed is dependent on the size, and is between 2,000 and 8,000rpm. The signal is transmitted contactlessly, and the electronic UT scan allows the detection of defects of a minimum 0.05 depth and measure thickness, and OD-ID ovalisation with ±2µm accuracy. The equipment is particularly suited to

been designed to withstand the tough environments in which NDT inspections are carried out, achieving IP66 standard for water and dust ingress and employing internal shock mounts to withstand impacts. Further outstanding results can be gained by

efficient and versatile scanning. Employing this partnership of products yields a reduction in inspection times and increased operator safety. Other scanners that partner well with the veo16:64 for pipe inspection include the Bracelet scanner – a low profile, small bore scanner (see page 101), the MultiMag and the MagScan, for scanning pipes and curved surfaces and are suitable for phased array techniques, TOFD and corrosion mapping. Sonatest Ltd and Phoenix ISL are able to provide consultation and advice for clients on all testing and inspection application challenges, and can provide bespoke solutions within the field of phased array and other NDT techniques.

operators in pipe and pipeline inspection by using phased array instrumentation together with automated scanners. Working alongside Phoenix Inspection Systems, which designs bespoke NDT systems for a global client base, the Sonatest veo can be partnered with several of the scanners from its comprehensive range, to provide a complete solution for pipework phased array inspections. The Magman, from Phoenix ISL, is a

scanner in the application of both longitudinal and circumferential pipeline inspection. This versatile scanner is capable of inspecting pipes down to a 50mm outside diameter. Using four independent magnetic wheels and capable of carrying up to 12 probes, the Magman scanner enables rapid,
