Detection of Hydrogen-Induced Cracking (HIC) - Olympus IMS
WEBThe first type is commonly referred to as hydrogen-induced cracking (HIC) and can occur where little or no applied or residual tensile stress exists. It is manifested as blisters or blister cracks oriented parallel to the plate surface.
Hydrogen Induced Cracking (HIC) from Advanced NDT Solutions
WEBPhased Array Technology (PAUT): PAUT is a very useful tool for evaluation of HIC damage, either using a 0° Linear Scan Technique or the more familiar Sectorial Scan (-30° to + 30°). Images for both of these techniques are shown below.
WEBA common damage mechanism of equipment in the oil & gas industry, is hydrogen induced cracking (HIC). This type of structural damage typically appears in equipment that undergoes a wet H2S service in elevated pressure and temperature profiles.
PAUT for Hydrogen Induced Cracking (HIC) - solutionss.org
WEBMicrocracks brought on by HIC that would not be visible to the unaided eye or identifiable using conventional NDT techniques can be found utilizing PAUT. Early HIC detection can lower maintenance costs, minimize downtime, and assist prevent catastrophic failures.
WEBHydrogen blistering (HB) or hydrogen-induced cracking (HIC) may occur in pressure-bearing pipes operating in hydrogen and wet hydrogen sulfide environments due to hydrogen accumulation in steel.
WEBTFM stands for Total Focusing Method. TFM has been found to be one of the tools useful in verifying and characterising HTHA and detecting connections in HIC blistering. This is an advanced Phased Array Ultrasonic Technique providing high resolution imaging capabilities.

WEBRAMESH PARISE. Hydrogen Damage Mechanism (HDM) and its reliable detection is the greatest problem faced in the petrochemical industries. Hydrogen Induced Cracking (HIC), Step Wise Cracking (SWC), Stress Oriented Hydrogen Induced Cracking (SOHIC) are different morphologies of HDM.
HIC/SOHIC Testing - Insight NDE
WEBFor equipment that cannot be inspected with magnetic particle testing, the next best form of HIC testing is phased array ultrasonic testing (PAUT), which is also convenient and reliable. Hydrogen corrosion can be treated with a hydrogen bake-out.
Hydrogen Induced Cracking Damage Estimation and Evaluation
WEBOct 18, 2021 · New non-destructive testing (NDT) inspection technology, quantification of damage, and tensile testing, has enabled the assessment of conservatism associated with the hydrogen induced cracking (HIC) damage parameter (DH) currently used in API 579 – 1/ASME Fitness-For-Service (FFS) Part 7.
