I assume that attenuation measurement, backwall echo measurement or velocity measurements(thus the poisson ratio) can be used but I am now sure of thier accuracy? Is there any acceptance and rejection criteria for evaluating the severity level of this hydrogen attack? Your urgent reply is highly appreciated. Thank you.         Reply  Translate  Close   David Hermanutz Consultant, Hbndt.com, China, Joined Jul 2012, 85 David Hermanutz Consultant, Hbndt.com, China, Joined Jul 2012 85 02:56 Jul-13-1999 Re: Measurement of Hydrogen attack in steel pipe : Can anyone help me to suggest the most accurate ultrasonic procedure to measure : the presence of hydrogen attack in steel pipes applicable to petrochemical industry.

Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI). > 2 Showcases SONOAIR - air-coupled Phased Array Ultrasonic Inspection System StandSONOTEC Ultraschallsensorik Halle GmbH For highly attenuating materials, the performance of the system is critical. The ultrasonic sensors, ... the scanning area and the system settings should be flexibly adapted to the test task and the material. These high expectations are met with the new and modular testing system SONOAIR. With the world’s first air-coupled phased-array UT inspection system SONOAIR we developed a technology that works with up to 4 transmitter and receiver channels with freely configurable square wave burst transmitters as wells as low noise receiving amplifiers. > 5 Showcases5 Videos High-performance Linear Phased Array Probes StandPhoenix Inspection Systems Limited Available to order from stock in a range of 5MHz – 7.5MHz and from 16 to 64 elements.
