Danieli Breda steel extrusion technology selected for two Projects

To address the increasing demand of the market for stainless steel and Corrosion Resistance Alloy (CRA) pipes, mainly for oil and gas, chemical, food processing, and automotive applications, two companies relied on Danieli for their investments.

Chinese company Zhejiang Jiuli Hi-Tech Metals reconfirmed its trust in Danieli Breda by ordering a new, 20-MN steel extrusion plant capable of producing seamless stainless-steel pipes with diameters ranging from 33 to 68 mm and wall thicknesses from 3 to 8 mm.

This order follows those for a 35-MN steel extrusion press and its upgrading to 42 MN.

In India, Stella Metal & Tubes awarded Danieli Breda the order for a 20-MN steel extrusion plant to be installed in the Gujarat state, in the western part of India.

Seamless stainless-steel pipes produced by Stella Metal & Tubes will range from 33 to 68 mm dia, and wall thicknesses from 3 to 8 mm, according to market request.

Both plants will feature intensive use of robotic solutions for management of tools and the other critical phases of the cycle. Automated control of tool sizes will be implemented using 3D vision systems. The temperature of billets and extruded tubes at press exit also will be monitored and controlled to minimize process parameter fluctuations and collect data for process visualization, post-processing analysis and optimization. This will allow a high level of process stability and therefore to maintain the highest product quality, with extrusion cycles taking place in less than 60 seconds.

With equipment manufactured at Danieli quality workshops, both plants are expected to be commissioned in 2026.
