    I-Spiral Submerged Arc Welding In Oil Pipe Line Construction: Ukuqinisekisa Impilo Yesevisi Nokuthembeka

    I-Spiral Submerged Arc Welding Ekwakhiweni Kolayini Wamapayipi Kawoyela: Ukuqinisekisa Impilo Yesevisi Nokuthembeka Kwesithombe Esifakiwe
    • I-Spiral Submerged Arc Welding In Oil Pipe Line Construction: Ukuqinisekisa Impilo Yesevisi Nokuthembeka

    Incazelo emfushane:

    Ukwakhiwa kweimigqa yamapayipi kawoyela kuyinqubo ebalulekile neyinkimbinkimbi edinga amazinga aphezulu kakhulu obuchwepheshe bokushisela.Phakathi kwezindlela zokushisela ezisetshenziswayo, i-spiral submerged arc welding (HSAW) igqama njengenketho yokuqala ngenxa yokusebenza kwayo okuphezulu nempumelelo ekuqinisekiseni impilo yesevisi nokuthembeka kwamapayipi kawoyela.Kule bhulogi, sizocubungula ukubaluleka kwe-HSAW ekushiseleni amapayipi kawoyela futhi sihlole izinzuzo zayo kanye nenani elikhulu lokuhlangana nomhlaba.'s ezikhulayo izidingo zokuthutha uwoyela.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Funda nge-HSAW:

    I-Spiral submerged arc weldingiwubuchwepheshe bokushisela obusezingeni eliphezulu obuhlanganisa izimiso zokushisela i-arc engaphansi kwamanzi kanye nokwakheka kweshubhu elivunguzayo.Kubandakanya ukusebenzisa inqubo yokushisela ezenzakalelayo ukuze udale ukushisela okuvunguzayo ngokuphakela ucingo oluqinile lokugcwalisa lube yi-arc embozwe nge-flux.Le ndlela iqinisekisa ama-welds angaguquki futhi aphezulu, asuse ingozi yokukhubazeka okuvamile nezinye izindlela zokushisela.

    Ukubaluleka kwe-HSAW ekwakhiweni kwamapayipi kawoyela:

    1. Amandla Nokuqina: Enye yezimfanelo eziyinhloko ze-HSAW yikhono layo lokwakha amajoyinti ashiselwe aqinile, aqine kakhulu.I-spiral weld eqhubekayo eyakhiwe yilobu buchwepheshe ithuthukisa ubuqotho besakhiwo futhi ibalulekile ukuze imelane nezingcindezi eziphezulu, amazinga okushisa aphezulu kanye nezici zemvelo.ipayipi lamafutha imigqaubuso ngesikhathi sempilo yabo yenkonzo.

    2. Impilo ende nokuthembeka okuqinile: Izintambo zamapayipi kawoyela kulindeleke ukuthi zisebenze ngokungenasici amashumi eminyaka, zithutha uwoyela ngaphandle kokuvuza noma ukwehluleka.I-HSAW idlala indima ebalulekile ekuzuzeni impilo ende yesevisi ngokuqinisekisa ngisho nokusatshalaliswa kokushisa okushiselayo, ukunciphisa ukugxila kwengcindezi, nokuvimbela ukuqaliswa kokuqhekeka nokusakazeka - zonke izici ezinomthelela ekuthembekeni kukonke kwepayipi.

    3. Ukwakhiwa okuphumelelayo: I-HSAW iyakwazi ukushisela ngokuqhubekayo izingxenye ezinde zamapayipi, ngakho isebenza kahle kakhulu ekwakhiweni kwamapayipi.Le ndlela inciphisa isikhathi sokushisela, yandisa ukukhiqiza, inciphisa kakhulu izindleko zokwakha, futhi ivumela ukuqedwa kwephrojekthi ngesikhathi.

    4. Ukulungiswa okuncishisiwe nokulungiswa: Ngokuhlinzeka ngezinsimbi zokushisela ezisezingeni eliphezulu, ezingenasici, i-HSAW inciphisa isidingo sokulungiswa kwesikhathi esizayo noma isikhathi sokuphumula esihlobene nokugcinwa.Amapayipi kawoyela akhiwe kusetshenziswa le ndlela awajwayele ukuvuza noma ukwehluleka, athuthukisa ukuphepha futhi andise ukusebenza kahle.

    5. Izinzuzo zemvelo: I-HSAW iqinisekisa ukukhiqizwa kokushisela okunembayo ngokunemba okuphezulu kobukhulu.Lokhu kunciphisa amathuba okugqwala kwamapayipi kanye nokuvuza kukawoyela okulandelayo, kuvikela indawo ezungezile ezinhlekeleleni ezingaba khona ezihlobene nokwehluleka kwamapayipi.

    a.Indlela ye-deoxidation ikhethwe kanje:

    FF: Insimbi ebulawe ngokuphelele equkethe izakhi zokubopha i-nitrogen ngamanani anele ukuhlanganisa i-nitrogen etholakalayo (isb. min. 0,020 % isiyonke i-Al noma i-0,015 % e-soluble Al).

    b.Inani eliphakeme kakhulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa inani elincane eliphelele lokuqukethwe kwe-Al elingu-0,020 % elinesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izakhi ezanele zokubopha i-N.Izinto ezibophezela i-N zizorekhodwa kuMqulu Wokuhlola.

    Ekuphetheni:

    Ukwakhiwa kwamapayipi kawoyela kudinga izindinganiso eziphakeme zokushisela ukuze kuqinisekiswe ukuphila isikhathi eside, ukwethembeka nokuphepha.I-Spiral submerged arc welding (HSAW) iwubuchwepheshe obufakazelwe obukhethwayo kulo mkhakha ngenxa yekhono layo lokwenza amashisela aqinile, aqinile futhi angenasici.Ngezinzuzo eziningi ezihlanganisa ubuqotho obuthuthukisiwe besakhiwo, ukwakhiwa okuphumelelayo, ukunakekelwa okuncishisiwe kanye nezinzuzo zemvelo, i-HSAW idlala indima ebalulekile ekuhlangabezaneni nezidingo zokuthutha uwoyela emhlabeni wonke.Njengoba imboni kawoyela iqhubeka nokukhula, ukusetshenziswa kobuchwepheshe bokushisela obusezingeni eliphezulu njenge-HSAW kubalulekile ekugcineni ubuqotho nokuthembeka kwamapayipi kawoyela emhlabeni wonke.

    Ipayipi le-SSAW

    Ngokufigqiwe

    I-Cangzhou Spiral Steel Pipe Group Co., Ltd. iyaziqhenya ngokuhlinzeka ngamapayipi okuthunga asonga aphezulu ezinhlelo zokusebenza ezihlukahlukene.Sigxila ekukhiqizeni okunembayo, ubuchwepheshe bokushisela obusezingeni eliphezulu kanye nezinto ezisezingeni eliphezulu ukuze sinikeze amakhasimende izixazululo ezinokwethenjelwa, ezisebenzayo zezidingo zabo zamapayipi.Sithembe ukuthi sizohlangabezana nazo zonke izidingo zakho futhi uzibonele mathupha ukwethembeka nokuqina kwamapayipi ethu othungelwano oluzungezayo.
