GB/T5310-2008seamless steel tube ke mofuta oa tšepe ea boleng bo holimo. The boiler tube e arotsoe ka kakaretso ea boiler tube le khatello e phahameng ea boiler ho latela ts'ebetso ea eona ea mocheso o phahameng. Pipe ea boiler ea khatello e phahameng e sebelisoa haholo bakeng sa ho etsa li-boilers tsa khatello e phahameng le ka holim'a khatello ea mouoane, liphaephe le tšepe e 'ngoe ea boleng bo holimo ea khabone, tšepe ea sebopeho sa alloy le phala ea tšepe e sa keneleng mocheso. [1] Li-boiler tubes tsena li sebetsa ka mocheso o phahameng le khatello, li hlahisa khase e phahameng ea mocheso oa mocheso le mouoane oa metsi, tse atisang ho ba le oxidation le corrosion.

Sehlopha sa tšepe

(1) boleng bo phahameng ba carbon structural tšepe tšepe 20G, 20MnG, 25MnG. 

(2) Alloy sebopeho tšepe 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, joalo-joalo. 

(3) Mafome mocheso manganga tšepe ka tloaelo sebelisoa 1Cr18Ni9, 1Cr18Ni11Nb boiler tube, ho phaella ho etsa bonnete ba sebopeho lik'hemik'hale le thepa ea mechine, ho etsa tlhahlobo ea khatello ea metsi, ho etsa tlhahlobo ea ho chesa, ho hatella. Li-tubes tsa tšepe li tsamaisoa maemong a kalafo ea mocheso. 

Ntle le moo, microstructure, boholo ba lijo-thollo le lera la decarburization ea li-tubes tse phethiloeng tsa tšepe le tsona lia hlokahala.
