Thyssenkrupp Steel is supplying approximately 1,000 tons of CO2-reduced Bluemint steel for a major water pipeline project in Angola, located in southwestern Africa. The material will be used as part of the Quilonga Grande development project, which is intended to fundamentally improve the water supply for the capital city of Luanda in the future.
The Bluemint steel hot-rolled strip produced by Thyssenkrupp Steel is processed into spiral-welded pipes at Mannesmann Grossrohr in Salzgitter. The pipes reach lengths of 13.5 meters and, depending on the route section, diameters ranging from 508 mm to 1,626 mm. In this project, Bluemint steel is used in particular for pipes with a diameter of 1,220 millimeters and a wall thickness of around 12 millimeters. In total, the new water system comprises approximately 105 kilometers of pipeline.
The new water transport system will play a central role in supplying die city of Luanda. The metropolis, with a population of around ten mln, has faced a massive drinking water deficit of approximately 1.2 mln cubic meters per day for years. In many districts, water has so far been supplied primarily by tanker trucks. The new water pipeline is a key component for a reliable and sustainable water supply for the population.
Bluemint recycled is a CO2-reduced steel from Thyssenkrupp Steel in which a specially processed scrap product is used in the blast furnace process. By using recycled material, primary raw materials can be conserved and process‑related CO2 emissions significantly reduced, without compromising the usual mechanical or processing properties.
