Germany-based steelmaker thyssenkrupp Steel has announced that it is supplying around 1,000 mt of carbon-reduced bluemint® steel for a major water pipeline project in Angola, aimed at improving long-term water supply for the capital city, Luanda.
The material will be used in the Quilonga Grande project, a key infrastructure development designed to address the city’s ongoing drinking water shortage.
The hot-rolled strip produced in Duisburg will be processed into large-diameter spiral-welded pipes by Mannesmann Grossrohr in Salzgitter. The pipes will have lengths of up to 13.5 meters and diameters ranging from 508 mm to 1,626 mm, with bluemint® steel primarily used for pipes measuring 1,220 mm in diameter and approximately 12 mm in wall thickness.
Pipeline project to address Luanda’s water deficit
The total pipeline system will extend approximately 105 kilometers and is expected to play a central role in supplying water to Luanda, a city of around 10 million people that currently faces a daily drinking water deficit of about 1.2 million cubic meters.
According to the company, the project represents an important step toward establishing a reliable and sustainable water supply system, as many districts currently rely on water delivered by tanker trucks.
Low-carbon steel supports sustainable infrastructure
Thyssenkrupp Steel stated that the use of bluemint® steel supports sustainable infrastructure development, as the material is produced with reduced carbon emissions through increased scrap usage in the blast furnace process, without affecting mechanical or processing properties.
The Quilonga Grande project highlights the integration of low-carbon materials into large-scale infrastructure developments, contributing to more resilient and climate-friendly supply systems.
