Prof. Han’s research interests include (1) Localized corrosion mechanism understanding and characterization, especially the interaction of mechanical and chemical effects, such as corrosion fatigue, stress corrosion cracking and hydrogen embrittlement for various materials in harsh environments; (2) Corrosion prevention techniques such as nanocomposite coatings, plating, inhibitors & cathodic protection; (3) Service lifetime prediction, failure analysis and integrity for engineering structure and components by big data modelling, digital twins & artificial intelligence (AI); (4) R & D of corrosion resistant alloys (including HEAs) in severe industry environment including new energy industries, energy storage and sea water.
Invited Lecture: Corrosion and integrity of buried oil and gas pipelines
Abstract: The pipeline is one of the important transportation methods for oil and gas. Corrosion is the main issue to affect pipeline’s safety and integrity. The buried pipeline not only has both internal corrosion and external corrosion, but also has the various loads including internal pressure, external soil pressure, and possible soil movement etc. The corrosion pit always exist on both internal and external surface, and the stress corrosion cracking may initiate from the pits and affect the integrity of pipelines. Traditional evaluation methods helps but could not predict properly. The lecture proposed the “corrosion/crack equivalent methods”, that is to simplify the pits as a crack and to use fracture mechanics to evaluate the integrity of pipeline. The methods become the China Standard and has been applied in industry. In order to solve the safety and reliability for the hydrogen doped natural gas pipeline, the effect of various parameters was studied. The results show that the hydrogen does increase the SCC sensitivity of pipeline steel.
