Mokhoa oa tlhahiso
Ts'ebetso ea tlhahiso ea liphaephe tsa tšepe e se nang seamless e arotsoe ka phala e chesang le e batang e se nang seamless.
1. Ts'ebetso ea tlhahiso ea peipi ea tšepe e se nang seamless e chesang: tube billet → futhumatsang → perforation → rolara e meraro/ho pitika le ho bilika ka ho tsoelang pele → de-pipe → sizing → pholiso → ho otlolla → tlhahlobo ea haeteroliki → ho tšoaea → pipe ea tšepe e se nang seam e nang le phello e matla e fumanoeng.
2. Ts'ebetso ea tlhahiso ea li-tubes tsa tšepe tse se nang metsi tse batang: tube e se nang letho → futhumatsang → perforation → sehlooho → annealing → pickling → ho tlotsa oli → ho penta ka makhetlo a mangata a batang → tube e se nang letho → phekolo ea mocheso → ho otloloha → tlhahlobo ea hydraulic → ho tšoaea → polokelo.
