Stainless Steel Tube – How Is It Made?
A stainless steel tube is basically a closed shaped structure which is used in numerous structural functions. The shape of a stainless steel tube can be round, square or rectangular or as per the requirement of manufacturing a particular application. A 1 inch of round tube has 1 inch outside diameter whereas, a 1 inch round pipe has 1 inch inside diameter. The reason behind this is that the external parts of the tubes are important in building structures and the internal parts of the pipes are important in the flow of fluid. There are mainly two primary types of steel tubing: seamless and welded. The latter begins as a flat strip whereas, the former starts in a melting furnace. 1. Seamless: Primarily the manufacture process of a seamless tubing starts from an electric arc furnace. The steel is later cast in an ingot or cast repeatedly as a bloom. The latter is then rolled in a billet which later on becomes a tube by being drawn over a piercing tool with the help of two external rollers
