Ipayipi le-Carbon Steel elingenamthungo
Ipayipi Lensimbi Elingenamthungo lenziwe ngensimbi eqinile eyindilinga'billet'eshiselwa futhi iphushwe noma idonswe phezu kwefomu kuze kube yilapho insimbi ibunjwa ibe yishubhu elingenalutho.Ipayipi elingenamthungo libe seliqedwa libe ukucaciswa kobukhulu nokuqina kodonga ngosayizi ukusuka ku-1/8 intshi ukuya ku-32 intshi OD.I-Carbon Steel Seamless Pipes / Tubes Insimbi yensimbi iyingxubevange ehlanganisa insimbi nekhabhoni.Iphesenti lekhabhoni ensimbi lithinta ubulukhuni, amandla okunwebeka kanye ne-ductility ye-carbon steel.Ipayipi le-carbon steel engenamthungo noma ingot yensimbi eqinile yenziwa ngeshubhu le-capillary ngokusebenzisa imbobo, bese kwenziwa ucingo olugoqiwe olushisayo, olubandayo noma olubandayo.Ipayipi lensimbi elingenamthungo embonini yensimbi yaseChina linesikhundla esibalulekile.Impahla yepayipi lensimbi yensimbi engenamthungo iyishubhu eliyindilinga, imibungu yomshini wokusika amapayipi ukuze idlule ekusikeni okungaba ngu-1 m ubude, futhi ithunyelwe ukushisisa kwesithando somlilo sebhande elihambisayo.I-Billet ifakwa esithandweni sokushisa, izinga lokushisa lingaba ngu-1200 degrees Celsius.I-fuel i-hydrogen noma i-acetylene.Ukulawulwa kwezinga lokushisa kwesithando yinkinga eyinhloko.Ishubhu eliyindilinga laphuma lizobhoboza umshini ngomfutho womoya.Ngokuvamile, i-punch ejwayelekile kakhulu ingumshini wokubhoboza we-tapered roll, i-punch ephezulu yokukhiqiza, ikhwalithi yomkhiqizo, ukunwetshwa kwembobo enkulu, ingagqoka insimbi ehlukahlukene.Ukubhobozwa, ishubhu eliyindilinga bekulokhu kugingqika, ukugingqika noma ukuphuma.Ikhishwe kushubhu ngemuva kokulinganisa.Ukulinganisa ngezimbobo ze-rotary cone ezinesivinini esikhulu ku-billet ukuze kwakheke ishubhu.Ububanzi bepayipi ngomshini wokulinganisa ukuze kutholwe ubude bobubanzi bokubhoboza.Ngemva kwepayipi ngokulinganisa embhoshongweni wokupholisa, ukupholisa ngesifutho samanzi, insimbi emva kokupholisa, kufanele iqondiswe.Ngemuva kwebhande lensimbi elithunyelwe ngomshini wokuhlola insimbi yokuqondisa (noma ukuhlolwa kwengcindezi) ukuhlola kwangaphakathi.Uma ipayipi liqhekeka ngaphakathi, amabhamuza nezinye izinkinga zizotholwa.Ngemuva kwepayipi kodwa futhi ngokukhetha okuqinile kokulawulwa kwekhwalithi.Ikhwalithi yensimbi, ukusetshenziswa kwezinombolo zopende wesifutho, imininingwane, inombolo yenkatho yokukhiqiza.Nge-crane engena endlini yokugcina impahla.

Ukwelashwa okungaphezulu kwepayipi lensimbi: Ukuze kuthuthukiswe impilo yesevisi yepayipi likawoyela, ukwelashwa kwendawo ngokuvamile kuyenziwa ukuze kube lula ukuhlanganiswa okuqinile kwepayipi lensimbi kanye ne-anticorrosive coating. Izindlela zokucubungula ezivamile yilezi: ukuhlanza, ukuchithwa kwamathuluzi, ukuchotshozwa, ukuqhunyiswa kokudubula. izigaba ezine.I-1 yokuhlanza Amafutha, uthuli, i-lubricant, i-organic matter enamathela phezu kwepayipi lensimbi, ngokuvamile isebenzisa i-solvent, i-emulsion ukuhlanza indawo. izindlela zokwelapha ziyadingeka.Ukususwa kokugqwala kwethuluziIpayipi lensimbi elingaphezulu kwe-oxide, ukugqwala, i-welding slag, lingasebenzisa ibhulashi lensimbi yensimbi ukuze lihlanze futhi lipholishe indawo yokwelapha.Ukukhipha ithuluzi kungahlukaniswa kube imanuwali namandla, ithuluzi lemanuwali derusting lingafinyelela ku-Sa 2 level, amandla ukuchithwa kwethuluzi kungafinyelela izinga le-Sa3. Uma ubuso bepayipi lensimbi buhlanganiswe nesikhumba esiqinile se-oxide, kungase kungenzeki ukususa ukugqwala ngosizo lwamathuluzi, ngakho-ke sidinga ukuthola ezinye izindlela.3 pickling Izindlela ezivamile zokukhetha zihlanganisa ikhemistri kanye ne-electrolysis.Kodwa ukucotshwa kwamakhemikhali kuphela okusetshenziselwa ukuvikela ukugqwala kwepayipi.Ukucosha ngamakhemikhali kungafinyelela izinga elithile lokuhlanzeka kanye nokubamadlakela ebusweni bepayipi lensimbi, elilungele imigqa yehange elandelayo.Ngokuvamile njenge-a ukudubula (isihlabathi) ngemva kokucubungula kabusha.4 shot ukuqhuma ukuze kukhishwe ukugqwalaNgenjini enamandla amakhulu ukushayela ama-blades azungezayo anesivinini esikhulu, igrit yensimbi, isibhamu sensimbi, ingxenye, amaminerali nolunye izintambo ezilumayo ngaphansi kokusebenza kwamandla aphakathi nendawo kusifutho sepayipi lensimbi kanye nokukhishwa okukhulu, susa ukugqwala, ama-oxide. kanye nokungcola ngakolunye uhlangothi, ngakolunye uhlangothi, ipayipi lensimbi ngaphansi kwesenzo somthelela wodlame olubi namandla okungqubuzana, ukuze kuzuzwe ubulukhuni obufanayo obudingekayo.Phakathi kwezindlela ezine zokwelapha, ukudubula ukuqhuma nokususa kuyindlela ekahle yokwelapha yokususa ipayipi.Ngokuvamile, ukuqhunyiswa kwesibhamu kanye nokususa insimbi kusetshenziselwa ikakhulukazi ukwelashwa kwendawo yangaphakathi yepayipi lensimbi, futhi ukudubula nokususa ipayipi kusetshenziswa kakhulu ukwelapha ngaphandle kwepayipi lensimbi.
