China ASTM A53 Gr.B Hot Koloiloe Carbon Seamless Steel Pipe
Tlhaloso e Khutšoanyane:
Pipe ena ea Alloy Steel e nang le 12cr1MOV Material ke phala ea tšepe e sa tsitsang e ka sebelisoang ho petroleum, lik'hemik'hale, matla a motlakase le lits'ebetso tsa boiler.E na le litšobotsi tsa ho hanyetsa serame, ho hanyetsa mocheso le ho hanyetsa kutu.12Cr1MoV ke mofuta oa phala ea motsoako.Sepheo se seholo ke ho etsa likarolo tsa mohaho oa tšepe ka har'a boiler.
Ho latela molao-motheo oa "boleng, tšebeletso, katleho le kholo", re fumane litšepo le thoriso ho tsoa ho moreki oa lehae le oa machabeng bakeng sa China ASTM A53 Gr.B Pipe ea Tšepe e Chesang ea Carbon e Seamless, Bakeng sa lipotso tse ling kapa haeba u ka ba le potso mabapi le thepa ea rona, etsa bonnete ba hore u seke oa tsilatsila ho re letsetsa.
Ho latela molao-motheo oa "boleng, tšebeletso, katleho le kholo", re fumane litšepiso le thoriso ho tsoa ho bareki ba malapeng le ba machaba bakeng saPipe ea tšepe ea China le Pipe ea Carbon, Re ntse re eketsa karolo ea rona ea 'maraka ea machaba ho latela thepa ea boleng, litšebeletso tse ntle, theko e utloahalang le ho fana ka thepa ka nako.Ka kopo ikopanye le rona ka nako efe kapa efe bakeng sa tlhaiso-leseling e batsi.
Thempereichara ea tšebeletso ke 580 ℃, 'me poleiti ea tšepe e hlokahalang ho ba le matla a phahameng a ho mamella mocheso o phahameng.Letlapa la tšepe le fanoa ka boemo bo tloaelehileng le bo halefileng.12Cr1MoVG alloy pipe e thehiloe holim'a tšepe ea boleng bo holimo ea khabone, 'me karolo e le' ngoe kapa tse 'maloa tsa alloy li eketsoa ka nepo ho ntlafatsa thepa ea mochini, ho tiea le ho thatafala ha tšepe.Lihlahisoa tse entsoeng ka tšepe e joalo hangata li hloka phekolo ea mocheso (normalizing kapa quenching le tempering);Likarolo le likarolo tse entsoeng ka tsona hangata li hloka ho tima le ho futhumatsa kapa kalafo ea lik'hemik'hale e holim'a metsi (carburizing, nitriding, joalo-joalo), quenching ea holim'a metsi kapa ho tima maqhubu a mangata pele e sebelisoa.Ka hona, ho ea ka lihlopha tse fapaneng tsa lik'hemik'hale (haholo-holo lihlahisoa tsa carbon), mekhoa ea phekolo ea mocheso le lisebelisoa, litšepe tse joalo li ka aroloa hoo e ka bang litšepe tse nang le carburized, Quenched le tempered le nitrided.
Ntlha ea pele, e ka sebelisoa hape ka 100%, ho boloka matla le ho sireletsa tikoloho.
Ea bobeli, e na le polasetiki e phahameng haholo 'me e ka sebelisoa bakeng sa tlhahiso ea bobeli le ts'ebetso.
Ea boraro, e na le conductivity e ntle ea mocheso le bokhoni bo phahameng ba mocheso.
Ea bone, e na le khanyetso e ntle ea oxidation le khanyetso ea kutu.
Ea bohlano, e na le ts'ebetso e ntle e batang le e chesang.
12Cr1MoVG ke mofuta oa phala ea tšepe ea chromium molybdenum alloy, eo likarolo tse ka sehloohong tsa lik'hemik'hale li leng carbon 0.08-0.15, silicon 0.17-0.37, manganese 0.40-0.70, phosphorus e seng ho feta 0.035, sebabole e seng ho feta 1000. molybdenum 0.25-0.35, alum 0.15-0.30, joalo-joalo.
Taba ea pele, e sebelisoa haholo ho etsa li-tubes tsa alloy tse nang le khatello e phahameng bakeng sa ho futhumatsa libaka tsa li-boilers tsa metsi ka khatello e phahameng le holimo.
Ea bobeli, e sebelisoa haholo ho li-superheaters, li-header le li-ducts tse kholo tsa mouoane oa malapeng a khatello e phahameng, khatello e phahameng haholo le li-boilers tsa li-subcritical power station.
Ea boraro, liphaephe tse kholo tsa bophara li sebelisoa haholo-holo e le lihlooho le Li-Conduits tse kholo tsa Mouoane tse nang le liparamente tsa mouoane ka tlase ho 565 ℃.
Taba ea pele, ho phalla ho chesang (phala ea tšepe e se nang seamless) ho phalla:
Round tube billet → futhumatsang → ho phunya → roll cross crossing → roll crossing or extrusion → pipe stripping → sizing (kapa ho fokotsa) → cooling → billet → straightening → hydrostatic test (kapa ho lemoha mefokolo) → ho tšoaea → polokelo.
Taba ea bobeli, ho toloka ho batang (rolling) ho phalla ha phala ea tšepe e se nang moeli:
Round tube billet → futhumatsang → ho phunya → sehlooho → annealing → pickling → pente ea oli (copper plating) → pente e ngata e batang (ho batang) → billet tube → kalafo ea mocheso → ho otlolla → tlhahlobo ea hydrostatic (kapa ho lemoha liphoso) → ho tšoaea → ho boloka thepa.
