Na peipi ea tšepe ea carbon ke peipi ea tšepe e cheselitsoeng?

Peipi ea tšepe ea carbon ha e na phala ea tšepe e cheselitsoeng. Pipe ea tšepe ea carbon e bua ka thepa e khethehileng ea phala ea tšepe ke tšepe ea carbon, e bolelang alloy ea tšepe ea carbon e nang le carbon content Wc ka tlase ho 2.11%. Ho phaella ho carbon, ka kakaretso e na le palo e nyenyane ea silicon, manganese, phosphorus, sebabole le litšila tse ling. le likarolo tse ling tse setseng. Ho phaella moo, pipe ena ea tšepe ea carbon e na le mefuta e mengata ea likopo, haholo-holo e sebelisoang ho haha, marokho, literene, likoloi, likepe le liindasteri tse sa tšoaneng tsa tlhahiso ea mechine.

Lipeipi tsa tšepe tsa carbon li ka aroloa ka liphaephe tse entsoeng ka carbon steel welded le carbon steel seamless liphaephe ho latela mokhoa oa ho etsa thepa.

Liphaephe tsa tšepe tse cheselitsoeng ka carbon li ka aroloa ka mefuta e meraro: liphaephe tsa tšepe tse otlolohileng tse ka tlas'a metsi, lipeipi tsa tšepe tse otlolohileng, le lipeipi tsa tšepe tse otlolohileng tsa maqhubu a phahameng ho latela mokhoa oa ho etsa seam.
Longitudinal welded pipe: The weld e ka mola o otlolohileng, kahoo e bitsoa otlolohileng seam welded pipe.
Spiral welded pipe: The weld seam e ka sebopeho sa spiral, se bitsoang spiral welding.

Mekhoa e meraro ea ho tjheseletsa e na le melemo le melemo ea eona, 'me ke efe e lokelang ho sebelisoa e itšetlehile ka litlhoko tsa moralo. Carbon steel welded steel pipe e ka sebelisoa masimong a mangata, joalo ka merero ea phepelo ea metsi le drainage, merero ea ho bokella, lipeipi tsa likhoerekhoere, phetisetso ea oli le khase, litšiea tsa meralo le merero e meng. Mokhoa oa hajoale oa tjheseletsa oa phala ea tšepe ea carbon steel welded haholo-holo e nang le mahlakore a mabeli a ka tlas'a metsi. Mokhoa ona oa welding o na le ts'ebetso e phahameng, boleng bo phahameng ba weld le bokaholimo bo boreleli.

Mokhoa oa tlhahiso ea lipeipi tsa tšepe tse se nang seamless:

Liphaephe tsa tšepe tse se nang moroalo tsa carbon li arotsoe ka mefuta e 'meli: lipeipi tsa tšepe tse chesang tse kolobisitsoeng (tse ntšitsoeng) le lipeipi tsa tšepe tse sa koalehang tse huloang ke serame ka lebaka la mekhoa ea tsona e fapaneng ea tlhahiso. Li-tubes tse batang (tse phuthiloeng) li arotsoe ka mefuta e 'meli: li-tubes tse chitja le li-tubes tse nang le sebōpeho se khethehileng.

1. Peipi ea tšepe e chesang (e ntšitsoeng) ea khabone e se nang seamless: tube e chitja billet → futhumatsang → ho phunya → rolling cross crossing → rolling crossing or extrusion → ho tlosoa ha tube → sizing (kapa ho fokotsa) → pholiso → ho otlolla → metsi Teko ea khatello ( kapa ho lemoha liphoso) → ho tšoaea → polokelo

Thepa e tala bakeng sa ho roala phala ea tšepe e se nang seamless ke tube billet e chitja, 'me embryo e chitja e lokela ho khaoloa ka mochini o sehang ho holisa li-billet tse bolelele ba mithara e ka bang 1, ebe e isoa seboping ka lebanta la conveyor. Billet e kenngoa ka seboping ho futhumatsa, mocheso o ka bang likhato tse 1200 tsa Celsius. Mafura ke hydrogen kapa acetylene. Taolo ea mocheso ka sebōping ke taba ea bohlokoa. Ka mor'a hore tube e pota-potileng e tsoe ka sebōping, e tlameha ho phunngoa ka ho phunyeletsa khatello. Ka kakaretso, motho ea phunyang haholo ke ea phunyang kholu. Mofuta ona oa ho phunya o na le ts'ebetso e phahameng ea tlhahiso, boleng bo botle ba sehlahisoa, katoloso e kholo ea bophara ba perforation, 'me e ka apara mefuta e fapaneng ea tšepe. Ka mor'a ho phunya, "tube" e pota-potileng e pota-potiloe ka ho latellana, e tsoela pele e phuthoa kapa e fetisoa ka meqolo e meraro. Ka mor'a extrusion, tube e lokela ho tlosoa bakeng sa boholo. Ho cheka mekoti ka lebelo le phahameng la rotary cone ka har'a billet ho etsa tube. Bophahamo bo ka hare ba phala ea tšepe bo khetholloa ke bolelele ba bophara ba ka ntle ba mochine oa ho phunya mochine oa boholo. Ka mor'a hore phala ea tšepe e be boholo, e kena ka tora e pholileng 'me e pholile ka ho fafatsa metsi. Ka mor'a hore phala ea tšepe e pholile, e tla otlolloa. Ka mor'a ho otloloha, phala ea tšepe e romeloa ho mochine oa tšepe oa tšepe (kapa tlhahlobo ea hydraulic) ka lebanta la conveyor bakeng sa ho lemoha phoso ea ka hare. Haeba ho na le mapetsong, li-bubble le mathata a mang ka har'a pipe ea tšepe, li tla fumanoa. Kamora tlhahlobo ea boleng ba liphaephe tsa tšepe, ho hlokahala khetho e tiileng ea matsoho. Ka mor'a tlhahlobo ea boleng ba pipe ea tšepe, penta nomoro ea serial, tlhaloso, palo ea lihlahisoa tsa tlhahiso, joalo-joalo ka pente. 'Me a phahamisoa ka tlung ea polokelo ka crane.

2. Peipi ea tšepe e batang (e phuthoang) ea tšepe ea khabone e se nang seamless: tube e chitja e se na letho →e futhumatsang→ e phunyeletsang→sehlooho→annealing→ho tlotsa→ho tlotsa → ho tlotsa oli (copper plating)→setako se batang se batang se batang)→sethapo se se nang letho→phekolo ea mocheso→Ho otlolla → tlhahlobo ea hydrostatic (ho lemoha liphoso) → ho tšoaea→ polokelo
