Feme e rekisoang ka ho fetesisa ea Cold Drawn Section Tube 1020 1045 20cr 40cr 27simn Precision Seamless Steel Pipe
Tlhaloso e Khutšoanyane:
Liphaephe tsa tšepe tsa mechine li sebelisoa likarolong tse entsoeng ka mochine kapa tse entsoeng bakeng sa indasteri, likoloi, mechine ea temo, lifofane, lipalangoang, ho tšoara thepa le thepa ea ntlo.E hlahisoa ho lekana bophara ba kantle le boholo ba botenya ba lebota.
E nang le mokhoa o phethahetseng oa taolo ea mahlale, boleng bo botle le bolumeli bo botle haholo, re iketselitse lebitso le letle mme ra lula sebakeng sena bakeng sa fektheri e rekisoang ka ho fetesisa ea Cold Drawn Section Tube 1020 1045 20cr 40cr 27simn Precision Seamless Steel Pipe, Sepheo sa rona se seholo ke ho fa bareki ba rona. lefatšeng ka bophara ka boleng bo botle, theko ea tlholisano, phano e khotsofatsang le litšebeletso tse ntle haholo.
E nang le mokhoa o phethahetseng oa taolo oa mahlale, boleng bo holimo le bolumeli bo botle haholo, re fumana lebitso le letle mme re nkile sebaka sena bakeng saChina Precision Seamless Steel Pipe le Cold Drawn Section Section Tube, Ho ba le khoebo e ngata ho feta.batho, re ntlafalitse lethathamo la lintho mme re batla tšebelisano e ntle.Webosaete ea rona e bonts'a lintlha tsa morao-rao le lintlha tse felletseng mabapi le lenane la rona la thepa le k'hamphani.Bakeng sa kananelo e eketsehileng, sehlopha sa rona sa litšebeletso tsa boeletsi Bulgaria se tla araba lipotso tsohle le mathata hang hang.Ba ikemiselitse ho etsa matsapa a bona a matle ho fihlela litlhoko tsa bareki.Hape re tšehetsa ho fana ka mehlala ea mahala.Liketelo tsa khoebo khoebong ea rona ea Bulgaria le feme hangata lia amoheleha bakeng sa lipuisano tsa katleho.Ke tšepa ho tseba tšebelisano-'moho e thabisang ea k'hamphani e sebetsang le uena.
Li-tubes tsa mochini li sebelisoa lits'ebetsong tsa mochini le tse bobebe tsa sebopeho.
Li-tubing tsa mechine li hlahisoa ho fihlela litlhoko tse khethehileng tsa tšebeliso ea ho qetela, litlhaloso, mamello le thepa ea lik'hemik'hale.
Liphaephe bakeng sa lisebelisoa tsa mochini le tse bobebe tsa sebopeho.Sena se lumella hore ho be le ho tšoana ho hoholo ha thepa ho pholletsa le phala ha ho bapisoa le liphaephe tse tloaelehileng kapa li-ducts.Li-tubes tsa mechine li ka hlahisoa ho ea ka litlhaloso tse tloaelehileng ha ho hlokahala, empa hangata li hlahisoa ho ts'ebetso e "tloaelehileng", ka sepheo sa mantlha sa matla a lihlahisoa bakeng sa litekanyo tse nepahetseng le botenya ba lebota.Lits'ebetsong tse ling tse entsoeng haholo, matla a lihlahisoa a ka 'na a se ke a hlalosoa,' me tlhahiso ea li-tubes tsa mechine e "lokela ho sebelisoa".Liphaephe tsa mechine li kenyelletsa mefuta e mengata ea lisebelisoa tsa meralo le tseo e seng tsa sebopeho.
Re sebelisa botsebi ba rona ba metallurgical le tlhahiso ho etsa lihlahisoa tsa mochini tse sebetsang hantle tse sebetsang hantle ho fihlela litlhoko tsa hau.
Sena se kenyelletsa k'habone, li-alloys esita le limaraka tse tloaelehileng tsa tšepe;annealed, normalized and tempered;khatello ea kelello e imolohile 'me ha e na khatello ea kelello;mme a tingwa mme a halefa.
Lipeipi tsa tšepe tse se nang seam bakeng sa mechini le likoloi, tse sebelisoang ho etsa le ho lokisa kutu ea koloi le liphaephe tsa axle tse ka morao, lisebelisoa tse nepahetseng, lisebelisoa le lisebelisoa.
Foreimi ea koloi le tube ea axle e ka morao.
Ho etsa le ho lokisa lisebelisoa tse nepahetseng, lisebelisoa le lisebelisoa.
Lipehelo tsa thomello: GBK, BKS, BK, BKW, NBK.
Hlahloba le ho etsa liteko:Sebopeho sa lik'hemik'hale, thepa ea mochini, tlhahlobo ea ponahalo le boholo, tlhahlobo e sa senyeheng, tlhahlobo ea boholo ba likaroloana.
Phekolo ea sefahleho:Ho qoelisoa ka oli, li-varnish, ho penta ho thunya.
