Advanced Testing and Structural Analysis for Assessment and Control of Hydrogen Damage in Structural Steels. Hydrogen offers the potential for reducing emissions in transport and energy generation industries as it is a low emission energy carrier. However, there remain questions in relation to the effects of hydrogen gas on the structural integrity of large structural steel components, such as gas distribution pipelines. The project aims to provide guidance on the safe use of hydrogen in high pr ....Advanced Testing and Structural Analysis for Assessment and Control of Hydrogen Damage in Structural Steels. Hydrogen offers the potential for reducing emissions in transport and energy generation industries as it is a low emission energy carrier. However, there remain questions in relation to the effects of hydrogen gas on the structural integrity of large structural steel components, such as gas distribution pipelines. The project aims to provide guidance on the safe use of hydrogen in high pressure vessels manufactured from low alloy ferritic steels. This project will increase confidence in relevant safety codes and standards, consequently increasing the likelihood of large scale uptake of hydrogen energy technologies. Read moreRead less
Improvement in Stress Corrosion Cracking Resistance of Stainless Steels in Environments Conducive to Localized Pitting Damage. Stress corrosion cracking (SCC) represents a serious threat to infrastructure exposed to chloride and caustic environments. The proposed project will characterize the chloride-SCC crack propagation parameters for a super duplex stainless steel, which is the material of construction for vessels for stripping vinyl chloride monomer in a PVC processing plant. Alarmingly hig ....Improvement in Stress Corrosion Cracking Resistance of Stainless Steels in Environments Conducive to Localized Pitting Damage. Stress corrosion cracking (SCC) represents a serious threat to infrastructure exposed to chloride and caustic environments. The proposed project will characterize the chloride-SCC crack propagation parameters for a super duplex stainless steel, which is the material of construction for vessels for stripping vinyl chloride monomer in a PVC processing plant. Alarmingly high numbers the welds (nearly 50%) in the vessel had suffered extensive pitting (which is a well-known SCC initiator) and SCC cracking. For the mitigation measures, the project will also investigate pitting and SCC susceptibility of weldments of alternative varieties of stainless steels, such as Zeron 100.Read moreRead less
