Nowadays, underwater pipelines transverse the oceans at depths down to 3,000 meters below sea level, while the latest projects envisage installations at even greater depths. Apart from the aggressive effects of salt water, pipelines must be able to withstand external pressures of 300 bar or more. In other words: the pressure on the material can be compared with the weight of an elephant standing on 50 millimeters of a grapefruit.

Only steel can withstand such forces − such as the special large-diameter pipes produced by the Mannesmannröhren-Werke that deliver oil and gas reliably to their destination − even under the most extreme external pressure.
