27SiMn Hot Rolled Seamless Steel Tube Alloy Seamless Steel Pipe
Tlhaloso e Khutšoanyane:
Lipeipi tsa tšepe tsa 27SiMn li sebelisoa haholo indastering ea likoloi, peterole, lik'hemik'hale le tsa likepe.27SiMn phala ea tšepe e tloaelehile ebile ea halefa, 'me e koahetsoe ka phosphate kahare le kantle.Pipe ena ea tšepe e sebelisoa haholo-holo sebakeng se tingoeng le se halefileng ho etsa likarolo tse chesang tsa litempe (likarolo tsa hydraulic) tse hlokang boima bo phahameng le ho roala ho hanyetsa, le likarolo tse chesang tsa ho hatakela tse hlokang boima bo phahameng le ho roala ho hanyetsa.
27SiMn seamless tšepe pipe e na le boima bo phahameng, bophara ba boima bo boima ka metsing ke 8 ~ 22mm, machinability e ntle, polasetiki e batang e bohareng le ho cheseha;Ho phaella moo, ho tiea ha phala ea tšepe ha ho fokotsehe haholo nakong ea phekolo ea mocheso, empa e na le matla a phahameng haholo le ho hanyetsa, haholo-holo ha metsi a tima.
