Mokhoa oa tlhahiso ea phala ea tšepe e se nang seamless

1. Hot rolling (extruded seamless tšepe phala): chitja phala billet futhumatsang perforation rolara tse tharo tšekamelo rolling, tsoela pele rolling kapa extruded tube bophara (kapa phokotso bophara bophara) cooling otlolohileng hydrostatic teko (kapa sekoli teko) letšoao bakeng sa polokelo.
2. Cold pull (rolled) seamless tšepe pipe: round pipe billet futhumatsang perforated head, annealed acid, annealed oil, oil plating (copper plating), multi-channel batang (ba batang rolled) billet pipe heat treatment straightening hydraulic test (ho lemoha phoso) tšoaea polokelong.
