Enbridge Pipeline System Line 55 (Flanagan to Cushing). As of 2013 there were expansion plans for the pipeline system which would, if permitted and fully built, provide the capacity to transport an amount of dilbit from the Athabasca oil sands into the United States and the Gulf Coast equal to that of the Keystone Pipeline. In 1991, Enbridge's Line 3 pipeline spilled 1.7 million gallons of oil in Grand Rapids, MN. This was the largest inland spill of oil ever in U.S. history. Deliberations over construction of a new Line 3 pipeline have drawn resistance from climate justice organizers and Native communities in
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
