Product Spotlight Extended Range Variable Wall® Piping Calibration Blocks for Longseam Inspection StandPH Tool Reference Standards This set of two blocks has been specially designed for situations where ultrasonic examination tak ... es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces. > 5 Showcases5 Videos Research Center IDEKO develops an ultrasonic train wheel inspection system for CAF StandIDEKO S.Coop The Basque Research centre IK4-IDEKO has developed a state-of-the-art ultrasonic inspection system f ... or the train wheel. This system secures a sound condition of train wheels and is thus a significant contribution to rail transport safety. The device was delivered to CAF recently and its use allows the manufacturer to become an approved supplier of rolling stock in Italy, as it meets the demanding homologation standards of this country. \\\\r\\\\n > 3 Showcases HARDNESS TESTER TKM-459CE combi StandMASHPROJECT LLC TKM-459CE combi applies 2 methods of hardness control: UCI and Leeb.
