A. Chidule cha kayendedwe ka ndondomeko
Kugudubuza kotentha (extrusion seamless steel chubu) : round chubu billet → kutenthetsa → perforation → kugudubuzika kotalikirana katatu, kugudubuza mosalekeza kapena kutulutsa → kutulutsa chubu → kukula (kapena kuchepetsa) → kuzizira → billet → kuwongola → kuyesa kwa hydrostatic (kapena kuzindikira zolakwika) → kuyika → kusungirako.
chubu chachitsulo chozizira (chokulungidwa) chosasunthika: chubu chozungulira → chotenthetsera → choboola → mutu → chowotcha → pickling → zokutira zamafuta (zophimba zamkuwa) → zojambula zozizira zambiri (zozizira) → billet → chithandizo cha kutentha → kuwongola → kuyesa kwa hydrostatic (kuzindikira zolakwika) → kuyika chizindikiro → kusungirako.
