Construction of the Trans-Alaska Pipeline System Construction of the Trans-Alaska Pipeline System The construction of the Trans-Alaska Pipeline System included over of oil pipeline, 12 pump stations, and a new tanker port. Built largely on permafrost during 1975–77 between Prudhoe Bay and Valdez, Alaska, the $8 billion effort required tens of thousands of people, often working in extreme temperatures and conditions; the invention of specialized construction techniques; and the construction of a new road, the Dalton Highway. The first section of pipe was laid in 1975 after more than five years of legal and political arguments. Allegations of faulty welds drew intense scrutiny from local 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
