Pantani Divisione Tubi has a long experience in production of bimetallic tubes for heat exchangers working in high critical corrosion process, generally applied in Chemical plants, Petrochemical plants and Desalination plants. Outer and Inner tube are in two different materials according to customer design and application needs. They are perfectly tied up to assure a correct heat transfer efficiency.
Sometimes it is necessary that bimetallic tube extremities are entirely made up of the inner tube material to permit a correct tube-to-tubesheet welding. In those case ferrules are required. Pantani Divisione Tubi has the possibility to provide bimetallic tubes with ferrules already assembled in.
