Brief description
Complete renovation of the compressed water line with constant pressure measurement DN450 and flange connections. The flange pipes were manufactured at the factory and transported to the construction site using a lorry. The assembly work includes the assembly of the old as well as assembly of the new line in the tunnel. Transport to the construction site was carried out by railroad transport cars which we designed and built ourselves.
