Tšepe e sa Khaotseng 309 Tube e se nang Seamless
Tlhaloso e Khutšoanyane:
Tšepe e sa Khaotseng 309 ke tšepe e sa khaoheng ea austenitic e hanelang mocheso e nang le chromium e ngata le nickel.
Teko ea Hydrostatic ea Pipe ea Tšepe e sa Khaotseng:
Tšepe e sa Senyeheng 309 e tsebahala ka ho hanyetsa mocheso ka tsela e ikhethang, e leng se etsang hore e lokele ho sebelisoa moo ho pepesehelang mocheso o phahameng ho tloaelehileng. Motsoako ona o fana ka khanyetso e ntle khahlanong le mafome, haholo-holo libakeng tse senyang hanyane. Chromium e ngata le nickel li tlatsetsa khanyetsong ea mafome ea motsoako ona le matla a mocheso o phahameng. Poleloana "seamless" e bontša hore tube e hlahisoa ntle le li-seams tse welded. Li-tube tse se nang seam hangata li khethoa lits'ebetsong tsa khatello e phahameng le mocheso o phahameng ka lebaka la sebopeho sa tsona se ts'oanang. Li-tube tse se nang seamless tsa Tšepe e sa Senyeheng 309 li fumana lits'ebetso liindastering tse fapaneng, ho kenyeletsoa le lifofane, ts'ebetso ea lik'hemik'hale, ts'ebetso ea mocheso, le tse ling, moo mocheso o phahameng le libaka tse senyang li kopanang teng.
