Challenge
Determining the minimum wall thickness for supercritical CO₂ pipelines requires consideration of multiple factors: internal design pressure, ductile fracture arrest, and dynamic pressure surges. While the design thickness for internal pressure can be readily calculated using ASME B31.4, the impacts of ductile fracture and surge pressures (similar to water hammer in liquid pipelines) are often discussed but seldom addressed in practical wall-thickness calculations.
