Economics

Hydrogen pipeline transport is used to transport hydrogen from the point of production or delivery to the point of demand. Although hydrogen pipeline transport is technologically mature, and the transport costs are similar to those of CNG, most hydrogen is produced in the place of demand, with an industrial production facility every

Piping

stainless steel Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's r ...

piping with a maximum hardness of 80 HRB is preferred. This is because higher hardnesses are associated with lower

fracture toughness In materials science, fracture toughness is the critical stress intensity factor of a sharp crack where propagation of the crack suddenly becomes rapid and unlimited. A component's thickness affects the constraint conditions at the tip of a ...

so stronger, higher hardness steel is less safe.
