Abstract: Accurate prediction of tensile strain capacity (TSC) is the key to the strain-based design and assessment (SBDA) of buried pipelines. Various TSC prediction models proposed by research institutions such as the Pipeline ...

Abstract: Corrosion is the main reason for the failure of CO2 pipelines. The corrosion behavior and mechanism of CO2 pipelines significantly differ from those of traditional oil and gas pipelines. The existing CO2 pipeline corrosion ...

Abstract: In the long-distance pigging operation of natural gas pipelines, severe wear of the sealing cups always leads to the failure and instability of the pig. Different from ordinary conditions, the wear process of the polyurethane ...

Abstract: The failure accidents in girth weld of pipelines occur frequently due to the combination of internal defects and external loads. However, the research on the fracture behavior of girth weld defects is relatively poor at ...
