Desing System
The Southern Gas Corridor project
Low-carbon, higher-niobium steels provide the enhanced properties and weldability required for thick-walled, large diameter pipelines transporting oil and gas at high pressures over vast distances.The Southern Gas Corridoris an example of one of many ambitious and high-profile projects using these steels.
The following interviews with members of the supply chain explain how a significant tonnage of steel produced using this alloying approach has played a vital role in arguably the world’s most strategically important gas pipeline of the current decade.

Significant long distance infrastructure projects, to expand the world’s oil and gas distribution network, have been steadily emerging across the continents. The pipe needed for such initiatives is now often required to be of the higher strength API 5L X70 or X80 grades and also tends to be of much larger diameter with increased wall thickness. These combined changes reflect the need to quickly transport increasing volumes of hydrocarbons at higher pressures.
