    Iingenelo Zokusebenzisa Iipayipi Zentsimbi Edibeneyo Ejikelezileyo Ene-Spiral Submerged Arc Kwimibhobho Yamanzi Engaphantsi Komhlaba

    Iingenelo Zokusebenzisa Iipayipi Zentsimbi Edibeneyo Ejikelezileyo Ejikelezileyo Engaphantsi Komhlaba Umfanekiso Ovezweyo
    • Iingenelo Zokusebenzisa Iipayipi Zentsimbi Edibeneyo Ejikelezileyo Ene-Spiral Submerged Arc Kwimibhobho Yamanzi Engaphantsi Komhlaba

    Inkcazo emfutshane:

    Xa ubeka imibhobho yamanzi engaphantsi komhlaba, kubalulekile ukukhetha uhlobo lombhobho oluchanekileyo ukuqinisekisa ukuqina kunye nobude bexesha. Ukhetho oludumileyo lwemibhobho yamanzi engaphantsi komhlaba yipayipi edibeneyo ejikelezayo, eyaziwa ngokuba yipayipi yentsimbi ye-SSAW.


    Iinkcukacha zeMveliso

    Iithegi zeMveliso

     Umbhobho wentsimbi we-SSAWluhlobo lombhobho ojikelezileyo we-arc ojikeleziweyo osetyenziswa rhoqo kwiindlela ezahlukeneyo zokusebenza, kuquka imigca yamanzi angaphantsi komhlaba. Inkqubo yawo eyahlukileyo yokudibanisa i-spiral ivelisa imibhobho emikhulu enobukhulu obufanayo bodonga, nto leyo eyenza ukuba ilungele ukuthuthwa kwamanzi angaphantsi komhlaba.

    Enye yezona nzuzo ziphambili zokusebenzisa umbhobho wentsimbi ofakwe kwi-spiral submerged arc kwimigca yamanzi angaphantsi komhlaba kukuqina kwawo okuphezulu kunye nokuqina kwawo. Inkqubo yokufakelwa kwe-spiral idala umbhobho oqinileyo nothembekileyo onokumelana noxinzelelo kunye nobunzima bokungcwatywa phantsi komhlaba. Olu qina lubalulekile ekuthinteleni ukuvuza kunye nokuqinisekisa ukuthembeka kwexesha elide kwemibhobho yamanzi.

    Ukongeza, umbhobho wentsimbi we-SSAW uyamelana nokugqwala, nto leyo eyenza ukuba ube lukhetho oluhle kakhulu lokusetyenziswa phantsi komhlaba apho imibhobho ivezwa kumswakama kunye nezinye izinto ezingqongileyo. Olu xhathiso lokugqwala lunceda ekwandiseni ubomi bemibhobho yakho kwaye lunciphise isidingo sokugcinwa nokulungiswa rhoqo.

    Umbhobho Womjelo Wamanzi Ongaphantsi Komhlaba

    Enye inzuzo yokusebenzisa umbhobho wentsimbi ofakwe kwi-spiral submited arc welded kwimigca yamanzi angaphantsi komhlaba kukuguquguquka kwawo kunye nokuguquguquka kwawo. Inkqubo yokudibanisa i-spiral inokuvelisa imibhobho enobubanzi obahlukeneyo, nto leyo eyenza ukuba ifaneleke kwiintlobo ngeentlobo zezicelo zemibhobho yamanzi. Ukongeza, ukuguquguquka kombhobho wentsimbi we-SSAW kwenza kube lula ukuwufaka nokusebenza, ingakumbi kwiindawo ezinomhlaba onzima okanye imiqobo.

    a. Indlela yokususa ioksijini ichazwe ngolu hlobo lulandelayo:

    FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto zokubopha initrogen ngobuninzi obaneleyo ukubopha initrogen ekhoyo (umz. ubuncinci be-0,020% iyonke ye-Al okanye i-0,015% ye-Al enyibilikayo).

    b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukwakheka kweekhemikhali kubonisa umxholo opheleleyo we-Al ongama-0,020% kunye nomlinganiselo ophantsi we-Al/N oyi-2:1, okanye ukuba kukho ezinye izinto ezaneleyo zokubopha i-N. Izinto zokubopha i-N mazirekhodwe kuXwebhu loHlolo.

    Ukongeza kumandla, ukuqina, kunye nokuguquguquka, umbhobho wentsimbi ofakwe kwi-spiral submiked arc welded ungabizi kakhulu xa uthelekiswa nezinye iintlobo zemibhobho. Inkqubo yokufakelwa kwe-spiral welding inciphisa iindleko zemveliso, nto leyo eyenza ukuba ibe lukhetho olungabizi kakhulu kwiiprojekthi ezinkulu zemibhobho yamanzi. Ukuqina kwexesha elide kunye neemfuno eziphantsi zokugcinwa kombhobho wentsimbi we-SSAW nazo zinegalelo ekongeni iindleko ngokubanzi kulo lonke ixesha lombhobho wamanzi.

    Umbhobho we-SSAW

    Lilonke, kukho iingenelo ezininzi zokusebenzisa umbhobho wentsimbi odibeneyo ojikelezileyo ojikelezileyo kwimigca yamanzi angaphantsi komhlaba, kubandakanya amandla aphezulu, ukuqina, ukumelana nokugqwala, ukuguquguquka, kunye nokusebenza kakuhle kweendleko. Ezi mpawu zenza ukuba ibe lukhetho oluthembekileyo nolusebenzayo lokuthuthwa kwamanzi angaphantsi komhlaba, nokuba kukwiziseko zophuhliso zikamasipala, usetyenziso lwemizi-mveliso, okanye iinjongo zezolimo.

    Ngamafutshane, xa kufikwa ekukhetheni umbhobho ongconokwimibhobho yamanzi engaphantsi komhlaba, umbhobho wentsimbi ofakwe kwi-spiral submerged arc welded yeyona ndlela ilungileyo. Ulwakhiwo lwayo olufakwe kwi-spiral lunika amandla, ukuqina kunye nokumelana nokugqwala okufunekayo ekusebenzeni ixesha elide, ngelixa ukuguquguquka kwayo kunye nokusebenza kakuhle kweendleko kuyenza ibe lukhetho olunomtsalane kwiiprojekthi zemibhobho yamanzi yazo zonke iisayizi. Ngokukhetha umbhobho wentsimbi ofakwe kwi-spiral submerged arc welded, unokuqinisekisa ukuthembeka kunye nobude bemibhobho yakho yamanzi engaphantsi komhlaba, ikunike uxolo lwengqondo kunye nokuzithemba kwinkqubo yakho yamanzi.
