The effect of pressurized hydrogen on pipeline walls is an important phenomenon that can cause damage to the integrity of the pipeline structure during transport and storage of gases. Hydrogen can penetrate the wall of metallic pipelines (alloy steel or carbon steel) and cause cracking or rupture of the material, which can lead to pressure loss or even serious effects (explosions, fires). The embrittlement of the metal by hydrogen is a phenomenon of degradation of the mechanical properties of the metal, as a resul...
