ultrasonic holograms and producing sound fields with superior properties. Increased productivity On-line at the pipe mill, the results can then be shown as simple indicators, identifying where in the pipe wall all flaws occur, to allow reliable ‘go/no go’ sentencing of the pipe. Alternatively, attention can be focused on particular sections of the pipe that require further investigation, and here a C-scan type inspection image is created. This more detailed data can then be analysed to provide information on how specific flaws are produced during manufacture, reducing the need for off-line prove-up. The additional data can then help to adjust the manufacturing process and so eliminate the source of pipe imperfections so that rejects are reduced and productivity increased. Productivity is also increased by ShapeUT’s intelligent, automated inspection system, which facilitates and simplifies change-over between different pipe batches, reduces operator dependency and is applicable to a wide range of inspection standards. The new system also saves on shop-floor space, because of its use of 2D arrays rather than multiple probe arrangements, and there is a significant reduction in spare parts inventory. Improved competitive edge Consequently, for the first time, the pipe manufacturer can now be certain of the actual integrity of the pipe being supplied to end users. Perhaps more importantly, the end user can have complete confidence in the fitness-for-purpose of the supplied product and in the quality assurance of the pipe supplier. As a result, the pipe manufacturer has a significant competitive edge over other manufacturers of seamless pipe who rely on traditional inspection techniques. Conclusion Non-destructive testing is an essential step in the manufacture of seamless tube and pipe. It must be carried out to meet accepted national and international quality standards and also to ensure that pipe produced is fit for purpose. This is especially the case in the oil and gas sector, both to ensure safety to employees and the environment and to avoid any financial losses resulting from pipe fracture. As a result, pipe manufacturers pay insurance or liability mitigation fees to reduce the financial impact of any in-service product failure. To date, no inspection system has been able to provide 360° gapless inspection for oblique flaws in seamless tube and pipe. ShapeUT fulfils this longstanding need and ensures that pipe manufacturers can have greater confidence in in-service performance of their products. Consequently, seamless pipe users can be sure that they are receiving a product of best-in- class quality, and pipe manufacturers can enjoy a competitive edge while improving productivity through better process optimisation.
