Hollow sections can be categorized into hot-rolled, cold-rolled, cold drawn, extruded, and other types based on different production methods.Hot-rolled seamless pipes are typically produced on automatic pipe rolling machines. Solid billets are inspected and surface defects are removed, cut to the required length, centered on the billet piercing end face, and then sent to the heating furnace for heating.
