Cast iron hollow bar, also known as cast iron tube or cast iron hollow cylinder, is a tubular component made of cast iron. It is characterized by its hollow, cylindrical shape with an empty interior. Cast iron hollow bars are produced through a casting process, where molten cast iron is poured into a mold with a hollow cavity in the desired shape and size.
Cast iron hollow bars are available in various sizes, diameters, and wall thicknesses to suit different applications. They can be produced from different grades of cast iron, such as gray iron or ductile iron, depending on the specific requirements of the application.
Cast iron hollow bars offer several advantages and features, including:
