A. Kakaretso ea phallo ea tšebetso
Hot rolling (extrusion seamless steel tube) : round tube billet → futhumatsang → perforation → crossing crossing 3-high, continuous rolling or extrusion → tube release → sizing (kapa ho fokotsa) → cooling → billet → straightening → hydrostatic test (kapa ho lemoha mefokolo) → ho tšoaea → polokelo.
Mohatsela o batang (o phuthotsoeng) oa tšepe o se nang seamless tube: round tube billet → futhumatsang → perforation → heading → annealing → pickling → pete ea oli (copper plating) → pente e batang e fetang e mengata (ho batang) → billet → kalafo ea mocheso → ho otlolla → tlhahlobo ea hydrostatic (ho lemoha liphoso) → ho tšoaea → polokelo.
