Incazelo
Ipayipi Lensimbi Elingenamthungo lenziwe ngensimbi eyindilinga eqinile 'ibillet' eshiswayo 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.

I-Painting & Coating
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.
1. Ukuhlanza I-Grease, uthuli, i-lubricant, i-organic matter ebambelele ebusweni bepayipi yensimbi, ngokuvamile isebenzisa i-solvent, i-emulsion ukuhlanza indawo. ngakho ezinye izindlela zokwelapha ziyadingeka.Ukususwa kokugqwala kwethuluzi Ipayipi lensimbi i-oxide surface, ukugqwala, i-slag yokushisela, ingasebenzisa ibhulashi lensimbi yensimbi ukuhlanza nokupholisha ukwelashwa okungaphezulu.
I-2.I-Tool derusting ingahlukaniswa ibe yi-manual namandla, i-manual tool derusting ingafinyelela izinga le-Sa 2, ithuluzi lamandla derusting lingafinyelela izinga le-Sa3. ukugqwala ngosizo lwamathuluzi, ngakho sidinga ukuthola ezinye izindlela.
3.I-Pickling Izindlela ezivamile zokukhetha zihlanganisa ikhemistri kanye ne-electrolysis.Kodwa ukucosha kwamakhemikhali kuphela okusetshenziselwa ukuvikela ukugqwala kwepayipi.Ukuqoqwa kwamakhemikhali kungafinyelela izinga elithile lokuhlanzeka kanye nokuba mahhadlahhadla ebusweni bepayipi lensimbi, elilungele imigqa yehange elandelayo.Ngokuvamile njenge isibhamu (isihlabathi) ngemva kokucubungula kabusha.
4.Ukudubula ukuze kukhishwe ukugqwala.Ngenjini enamandla amakhulu ukushayela ama-blade azungezayo anesivinini esikhulu, insalela yensimbi, isibhamu sensimbi, ingxenye, amaminerali kanye nolunye izintambo ezilumayo ngaphansi kwesenzo samandla aphakathi nendawo kusifutho sepayipi lensimbi kanye nokukhishwa okukhulu, susa kahle. ukugqwala, ama-oxides nokungcola ngakolunye uhlangothi, ngakolunye uhlangothi, ipayipi lensimbi ngaphansi kwesenzo sodlame oluvuthayo namandla okungqubuzana, ukuze kuzuzwe ubulukhuni obudingekayo. ukukhishwa kwepayipi.Ngokuvamile, ukuqhunyiswa kwesibhamu nokususa insimbi kusetshenziselwa ikakhulukazi ukwelashwa kwendawo yangaphakathi yepayipi lensimbi, futhi ukuqhuma nokususa isibhamu kusetshenziswa kakhulu ukwelapha ngaphandle kwepayipi lensimbi.
