Pipeline transport in order to avoid melting the frozen ground by hot petroleum which would result in sinking the pipeline in the ground. Maintenance of pipelines includes checking cathodic protection levels for the proper range, surveillance for construction, erosion, or leaks by foot, land vehicle, boat, or air, and running cleaning pigs, when there is anything carried in the pipeline that is corrosive. US pipeline maintenance rules are covered in Code of Federal Regulations(CFR) sections, 49 CFR 192 for natural gas pipelines, and 49 CFR 195 for petroleum liquid pipelines. In the US, onshore and offshore pipelines used to transport oil and
Hydrogen pipeline transport resist corrosion. The problem is compounded because hydrogen can easily migrate into the crystal structure of most metals. For process metal piping at pressures up to , high-purity stainless steel piping with a maximum hardness of 80 HRB is preferred. Composite pipes are assessed like: Fiber-Reinforced Polymer pipelines (or FRP pipeline) and reinforced thermoplastic pipes are researched. Hydrogen pipeline transport Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to transport hydrogen from the point of production or delivery to the point of demand. Although hydrogen pipeline
