Hollow sections are categorized by production methods, including hot rolled, cold rolled, cold drawn, and extruded tubes, etc.Hot-rolled seamless tubes are typically produced on automatic tube-rolling machines. The solid billets are inspected, surface defects are removed, cut to the required length, centered on the end face of the billet at the穿孔 end, and then sent to the heating furnace for heating.
