The tunnel made with SKUDO+PIPEPANEL is a brand-new concept aimed at reinforcing the furthest layer inside the EAF (Electronic Arc Furnace) in order to increase people’s safety by reducing the risks of water leakages. The cooled element is made of a copper cast with internal rectangular-section circuit and a panel composed of an iron coil where pressured water runs in. The two parts are welded together to make a one piece product.
