Stainless steel scrap is processed into pipes through a series of steps. First, the scrap is sorted and cleaned to remove any impurities. Then, it is melted in a furnace to form molten stainless steel. The molten steel is then cast into billets, which are solid blocks of stainless steel. These billets are then heated and passed through a series of rolling mills to reduce their thickness and lengthen them. The resulting stainless steel strips are then welded together to form long pipes. These pipes are further processed, including heat treatment and finishing processes, to meet the required specifications and standards.
