Another of Ensonify’s Lead Technicians has recently received the industry standard HTHA qualification from Lavenders International.
High temperature hydrogen attack (HTHA) is an irreversible deterioration of the mechanical properties of steel due to the reaction of hydrogen with carbon at temperatures in excess of 200°C. If left undetected, the once microscopic cracks at grain boundaries can propagate into extremely large surface breaking cracks which can affect plant integrity and result in failure of the asset.
Specialised PAUT/ToFD techniques have been developed for the detection of HTHA which require significant training on real hydrogen damaged samples, along with the latest Phased Array/ToFD equipment.
