Hot Hydrogen Attack (HHA) is degradation caused by the reaction of hydrogen with carbon, forming methane (CH4). Operational factors such as temperature and hydrogen pressure affect the occurrence of HHA which in turn can lead to extensive damage in industrial plants, particularly fertilizer plants and refineries.

SGS is delighted to offer a globally available and free webinar on Non-Destructive Testing (NDT) techniques for the identification and monitoring of a Hot Hydrogen Attack (HHA). The webinar, available across the globe in Asia, Europe, the Americas and Africa, will detail in an hour long session how to identify the material degradation of HHA and its differences to hydrogen induced cracking. In addition, Norbert Trimborn, the Strategic Business Leader for Advanced NDT at SGS, will detail the reasons for the worldwide HHA problem and related SGS techniques for the inspection of parent material. Norbert Trimborn will also enlighten participants with regard to SGS’s inspection approach to welding and heat affected zones and the relation between the inspection result and real damage.

SGS has a variety of highly advanced and proven techniques for the prevention and detection of Hot Hydrogen Attack, including Time of Flight Diffraction (TOFD), Automated Backscatter and Velocity Ratio Measurements. SGS can help when HHA is detected and its approach to the detection of HHA has more than twenty-five years’ worth of proven reliability and reproducibility.

With the SGS approach to inspection, you can be certain of the presence or absence of HHA and any attack is guaranteed to be detected at an early stage, with support also provided for the monitoring of an attack’s progress. SGS inspections are designed to be reliable and reproducible, as well as proven to detect Hot Hydrogen Attack in its early stages. SGS can present its results early, with monitoring facilities for an attack in progress also available. In addition, the use of Non-Destructive Testing ensures that the examination of an industrial site is non-intrusive, ensuring that time and cost savings are made. SGS is continuously seeking to develop its techniques and applications in the detection of HHA, and its services are available in more than thirty countries worldwide.

With the webinar offered by SGS, you can widen your knowledge on the detection and quantification of Hot Hydrogen Attack in just 60 minutes.
