    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.

    Inkqubo yokuvelisa

    Umbhobho odibeneyo ojikelezayo, okwaziwa ngokuba yi-SSAW (i-spiral submerged arc welded) pipe, wenziwa kusetyenziswa iindlela zokubumba i-spiral kunye neendlela zokubumba i-arc welding ezingaphantsi komhlaba. Inkqubo iqala ngonyango olusecaleni lomcu wentsimbi odibeneyo uze emva koko ugobe umcu ube yimo ye-spiral. Emva koko ukubumba i-arc welding ngokuzenzekelayo kusetyenziselwa ukudibanisa imiphetho yemicu kunye, kudala ukubumba okuqhubekayo kubude bombhobho. Le ndlela iqinisekisa ukuba ijoyinti iqinile kwaye ihlala ixesha elide ngelixa inciphisa iziphene kwaye igcina ukuqina kwesakhiwo.

    Iingenelo zombhobho wentsimbi yekhabhoni odibeneyo ojikelezayo

    1. Amandla nokuqina:Umbhobho wentsimbi yekhabhoni odibeneyo ojikelezayoyaziwa ngamandla ayo aphezulu kunye nokuqina kwayo, nto leyo eyenza ukuba ifaneleke kwizicelo ezifuna ukumelana noxinzelelo oluphezulu kunye nokusebenza ixesha elide.

    2. UkuSebenza kakuhle kweendleko: Ezi payipi zibonelela ngesisombululo esingabizi kakhulu ngenxa yenkqubo yazo yokuvelisa esebenza kakuhle, iindleko eziphantsi zezinto ezisetyenzisiweyo, kunye neemfuno zabasebenzi eziphantsi xa kuthelekiswa nezinye iintlobo zepayipi.

    3. Ukuguquguquka: Ukuguquguquka kombhobho wentsimbi yekhabhoni odibeneyo ojikelezayo kuvumela ukuba isetyenziswe kwiintlobo ngeentlobo zezicelo, kubandakanya ukuthuthwa kwamanzi, ukuthuthwa kweoyile negesi, izakhiwo zokufaka iipali, iinkqubo zokungcola, kunye neenkqubo ezahlukeneyo zoshishino.

    4. Ukuchaneka kobukhulu: Inkqubo yokwenza i-spiral inokulawula ngokuchanekileyo ubungakanani kunye nobukhulu bodonga lombhobho, iqinisekisa ukuchaneka kunye nokufana kwemveliso.

    Iindawo zokusetyenziswa

    1. Ishishini leoyile negesi yendalo: Imibhobho yentsimbi yekhabhoni edityanisiweyo nge-spiral isetyenziswa kakhulu kwishishini leoyile negesi yendalo, ingakumbi ekuthuthweni kweoyile ekrwada, igesi yendalo kunye neemveliso zepetroliyam. Amandla ayo kunye nokukwazi kwayo ukumelana neendawo ezinoxinzelelo oluphezulu kuyenza ilungele imibhobho ekude.

    2. Ukuhanjiswa kwamanzi: Nokuba kubonelelwa ngamanzi kamasipala okanye ngeenjongo zokunkcenkceshela, imibhobho yentsimbi yekhabhoni edityanisiweyo nge-spiral ibonelela ngesisombululo esigqibeleleyo ngenxa yokumelana kwayo nokugqwala, amandla kunye nokulula kokufakelwa kwayo.

    3. Inkxaso yolwakhiwo: Olu hlobo lombhobho lusetyenziswa kakhulu kushishino lokwakha ukubonelela ngenkxaso yolwakhiwo lwezakhiwo, iibhulorho, iidokhi kunye nezinye iiprojekthi zeziseko zophuhliso. Ukuqina kwazo kunye nokumelana kwazo nezinto zangaphandle kuzenza zithembeke kwezo zicelo.

    4. Ukusetyenziswa Kwemizi-mveliso: Imibhobho yentsimbi yekhabhoni edityanisiweyo ejikelezayo isetyenziswa kwiindawo ezahlukeneyo zoshishino ezifana nokucubungula iikhemikhali, izityalo zamandla kunye nemisebenzi yokwemba ngenxa yokukwazi kwayo ukumelana nobushushu obuphezulu, uxinzelelo kunye neendawo ezingcolisayo.

    Ukuququmbela

    Umbhobho wentsimbi yekhabhoni edibeneyo ejikelezayo, efana neUmbhobho we-X42 SSAW, iguqule inkqubo yokuwelda imibhobho yesinyithi, izisa iingenelo ezininzi kumashishini ahlukeneyo. Amandla azo, ukuqina, ukusebenza kakuhle kweendleko kunye nokuchaneka kobukhulu kuqinisekisa ukuthembeka kwesakhiwo kwiindlela ezahlukeneyo zokusebenza. Ukukwazi ukumelana noxinzelelo olugqithisileyo, amaqondo obushushu kunye neendawo ezirhabaxa kwenza ukuba ibe yeyona ifanelekileyo yokuhambisa ioyile negesi, ukunikezelwa kwamanzi kunye namanye amacandelo emizi-mveliso. Ke ngoko, xa kufikwa ekuwelda imibhobho yesinyithi, ukusetyenziswa kwemibhobho yentsimbi yekhabhoni edibeneyo kuhlala kuyisisombululo esithembekileyo nesisebenzayo sokuqinisekisa iziseko ezihlala ixesha elide nezizinzileyo.

    Uvavanyo lwe-Hydrostatic

    Ubude bombhobho ngamnye buya kuvavanywa ngumvelisi kuxinzelelo lwe-hydrostatic oluya kuvelisa eludongeni lombhobho uxinzelelo olungaphantsi kwama-60% wamandla aphantsi okuvelisa kubushushu begumbi. Uxinzelelo luya kugqitywa yile equation ilandelayo:
    P=2St/D

    Utshintsho Oluvumelekileyo Kubunzima Nobukhulu

    Ubude bombhobho ngamnye buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bawo abuyi kwahluka ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bawo obuqikelelwayo, kubalwe kusetyenziswa ubude bawo kunye nobunzima bawo ngobude beyunithi nganye.
    Ububanzi bangaphandle abuyi kwahluka ngaphezu kwe-±1% ukusuka kububanzi obuqhelekileyo bangaphandle
    Ubukhulu bodonga nangaliphi na ixesha abuyi kuba ngaphezulu kwe-12.5% ​​phantsi kobukhulu bodonga obuchaziweyo.
