You might contact manufacturers of online diameter gauges, some are mentioned in the Tube '96 report. See at: http://www.ndt.net/buyers/twd_96/twd_r.htm ....... Laser diameter gauges were very prominent at the show. This technique for inline diameter control is rapidly increasing in popularity, and we saw Laser Mike* at the crowded booth of Beta Instruments (specialists in UT and laser techniques)...... Laser diameter gauges are cheaper than UT but cannot find internal defects. Ultrasonic flaw detection in conjunction with diameter measurement technique is an applied technique and I personally did some work in this area. Inoex GmbH works in the field of equipment for online control in the plastic and cable industry (see NDTnet Exhibition) On NDTnet you may find more information at: http://www.ndt.net/article/rohrext/us_dia/us_dia_e.htm Chapter - Diameter measurement http://www.ndt.net/article/rohrext/us_ndt/us_ndt_e.htm Chapter - Ultrasonic Flaw Detection (Ultrasonic testing in Plastic Pipe extrusion) http://www.ndt.net/article/report/seattle/seattl_r.htm#10 .......A New Generation of Ultrasonic Systems for Dimensional Measurement of Tubing.

Product Spotlight Compact NDT inspection-heads for measurements with active thermography StandAT-Automation Technology GmbH The compact inspection head is suitable for thermographic ndt tasks. The uncooled infrared camera ... is specially developed for NDI-tasks and offers a thermal sensitivity until now known only from thermal imagers with cooled detector. All required components and functions are integrated into the inspection-head. You will only need an ethernet cable to connect the sensor with the evaluation system. > 2 Videos IntraPhase Athena Phased Array System StandWesDyne International (AMDATA Products) The Athena Phased Array system, manufactured by WesDyne NDE Products & Technology, consists of a pha ... sed array acquisition system and PC running IntraSpect software. A PC is used to perform acquisition, analysis and storage of the data. System hardware is capable of operating up to four data sets with any combination of phased array or conventional UT probes. NOW AVAILABLE IN 64-64 CONFIGURATION. > 9 Showcases Conformable wedge transducer StandIMASONIC SAS The conformability is obtained with a flexible membrane filled with water between the transducer and ... the inspected component. The coupling between the membrane and the component requires a small quantity of water or couplant. The conformable wedge combines the acoustic performance of immersion technique with good coupling and low attenuation. > FMC/TFM StandAdvanced OEM Solutions Next generation for Phased Array UT is here now with FMC/TFM! Have higher resolution imaging, impr ... oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are: Beautiful Image! Easier to understand what you're looking at Completely focused in entire image or volume Much easier to define setups before inspection Easier to decipher geometry echoes from real defects Oriented defects (e.g. cracks) are imaged better See image from different wave modes from one FMC inspection FMC data can be reprocessed/analyzed without going back to the field > 3 Showcases more Showcases
