Zusammenfassung:	PURPOSE:To prolong the life and also to reduce manufacturing cost by forming a covered steel tube by directly winding a thin sheet of a corrosion resistant metal around a steel tube. CONSTITUTION:The coverd steel tube is composed by spirally winding the corrosion resistant metal sheet 2 around the steel tube 1 while pulling the sheet and overlapping edges in the longitudinal direction of a belt-like metal or by winding while butting the edges and mutually joining the edges in the longitudinal direction. In this way, regardless of the large diameter or small diameter of the steel tube, there are such effects as covering with the corrosion resistant metal is easily secured and the life of the steel tube is prolonged.
