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.
Pipeline transport not used for economic and ecological reasons. The typical annual loss of thermal energy through distribution is around 10%, as seen in Norway's district heating network. District heating pipelines are normally installed underground, with some exceptions. Within the system, heat storage may be installed to even out peak load demands. Heat is transferred into the central heating of the dwellings through heat exchangers at heat substations, without mixing of the fluids in either system. Bars in the Veltins-Arena, a major football ground in Gelsenkirchen, Germany, are interconnected by a long beer pipeline. In Randers city in Denmark, the so-called Thor
