Trans-Arabian Pipeline years of constant arguing between Saudi Arabia and Syria and Lebanon over transit fees, the emergence of oil supertankers, and pipeline breakdowns, the section of the line beyond Jordan ceased operation in 1976. The remainder of the line between Saudi Arabia and Jordan continued to transport modest amounts of petroleum until 1990 when the Saudis cut off the pipeline in response to Jordan's support of Iraq during the first Gulf War. Today, the entire line is unfit for oil transport. The Trans-Arabian Pipeline was long with a diameter of . When constructed, it was the world's largest oil pipeline system.
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
