    Izinzuzo Zokusebenzisa Amapayipi Ensimbi Ahlanganisiwe Angaphansi Komhlaba Ane-Spiral Submerged Emapayipini Amanzi Angaphansi Komhlaba

    Izinzuzo Zokusebenzisa Amapayipi Ensimbi Ahlanganisiwe Angaphansi Komhlaba Angaphansi Komhlaba Angaphansi Komhlaba Izithombe Ezifakiwe
    • Izinzuzo Zokusebenzisa Amapayipi Ensimbi Ahlanganisiwe Angaphansi Komhlaba Ane-Spiral Submerged Emapayipini Amanzi Angaphansi Komhlaba

    Incazelo emfushane:

    Uma ubeka imigqa yamanzi engaphansi komhlaba, kubalulekile ukukhetha uhlobo olufanele lwepayipi ukuqinisekisa ukuqina nokuphila isikhathi eside. Ukukhetha okuthandwayo kwemigqa yamanzi engaphansi komhlaba ipayipi elihlanganisiwe elijikelezayo, elaziwa nangokuthi ipayipi lensimbi le-SSAW.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

     Ipayipi lensimbi le-SSAWuhlobo lwepayipi elihlanganisiwe elifakwe i-arc elihlanganisiwe elivame ukusetshenziswa ezinhlotsheni ezahlukene zezicelo, kufaka phakathi imigqa yamanzi angaphansi komhlaba. Inqubo yalo ehlukile yokushisela i-spiral ikhiqiza amapayipi amakhulu anobukhulu obufanayo bodonga, okwenza kube kuhle kakhulu ukuthuthwa kwamanzi angaphansi komhlaba.

    Enye yezinzuzo eziyinhloko zokusebenzisa ipayipi lensimbi elihlanganisiwe elifakwe i-spiral submited arc emigqeni yamanzi angaphansi komhlaba amandla alo aphezulu kanye nokuqina kwalo. Inqubo yokushisela ejikelezayo idala ipayipi eliqinile nelithembekile elingamelana nengcindezi kanye nesisindo sokugqitshwa ngaphansi komhlaba. Lokhu kuqina kubalulekile ekuvimbeleni ukuvuza nokuqinisekisa ubuqotho besikhathi eside bamapayipi amanzi.

    Ngaphezu kwalokho, ipayipi lensimbi le-SSAW liyamelana nokugqwala, okwenza kube ukukhetha okuhle kakhulu kokusetshenziswa ngaphansi komhlaba lapho amapayipi evezwa khona umswakama nezinye izici zemvelo. Lokhu kumelana nokugqwala kusiza ukwandisa impilo yamapayipi akho futhi kunciphisa isidingo sokulungiswa nokulungiswa njalo.

    Ipayipi Lomugqa Wamanzi Ongaphansi Komhlaba

    Enye inzuzo yokusebenzisa ipayipi lensimbi elihlanganisiwe elifakwe i-spiral submited arc emigqeni yamanzi angaphansi komhlaba ukuguquguquka kwalo kanye nokuzivumelanisa nezimo. Inqubo yokushisela ejikelezayo ingakhiqiza amapayipi anobubanzi obuhlukene, okwenza afanelekele ukusetshenziswa kwamapayipi amanzi ahlukahlukene. Ngaphezu kwalokho, ukuguquguquka kwepayipi lensimbi le-SSAW kwenza kube lula ukulifaka nokusebenza, ikakhulukazi ezindaweni ezinezindawo noma izithiyo ezinzima.

    a. Indlela yokususa i-oxidation ichazwa kanje:

    FF: Insimbi ebulewe ngokuphelele equkethe izinto zokubopha i-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isb. ubuncane be-0,020% iyonke i-Al noma i-0,015% i-Al encibilikayo).

    b. Inani eliphezulu le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kubonisa okuqukethwe okungenani kwe-Al okungu-0,020% kanye nesilinganiso esincane se-Al/N esingu-2:1, noma uma kukhona ezinye izinto ezibophayo ze-N ezanele. Izinto ezibophayo ze-N kufanele ziqoshwe kuDokhumenti Yokuhlola.

    Ngaphezu kwamandla, ukuqina, kanye nokuguquguquka, ipayipi lensimbi elihlanganisiwe elifakwe i-spiral submited arc lisebenza kahle uma liqhathaniswa nezinye izinhlobo zamapayipi. Inqubo yokushisela ejikelezayo inciphisa izindleko zokukhiqiza, okwenza kube inketho engabizi kakhulu kumaphrojekthi amakhulu amapayipi amanzi. Ukuqina kwesikhathi eside kanye nezidingo zokunakekelwa okuphansi kwamapayipi ensimbi e-SSAW nakho kunegalelo ekongeni izindleko kuyo yonke impilo yomugqa wamanzi.

    Ipayipi le-SSAW

    Sekukonke, kunezinzuzo eziningi zokusebenzisa ipayipi lensimbi elihlanganisiwe elingaphansi komhlaba elijikelezwe yi-spiral emigqeni yamanzi angaphansi komhlaba, okuhlanganisa amandla aphezulu, ukuqina, ukumelana nokugqwala, ukuguquguquka, kanye nokusebenza kahle kwezindleko. Lezi zimfanelo zenza kube inketho ethembekile nesebenzayo yokuthutha amanzi angaphansi komhlaba, kungaba ngengqalasizinda kamasipala, ukusetshenziswa kwezimboni, noma izinjongo zezolimo.

    Ngamafuphi, uma kukhulunywa ngokukhetha ipayipi elingcono kakhuluyemigqa yamanzi engaphansi komhlaba, ipayipi lensimbi elihlanganisiwe elihlanganiswe nge-spiral submarine yisinqumo esingcono kakhulu. Ukwakhiwa kwalo okuhlanganisiwe kunikeza amandla, ukuqina kanye nokumelana nokugqwala okudingekayo ukuze kusebenze isikhathi eside, kuyilapho ukuguquguquka kwalo kanye nokusebenza kahle kwezindleko kukwenza kube inketho ekhangayo kumaphrojekthi amapayipi amanzi abo bonke osayizi. Ngokukhetha ipayipi lensimbi elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe, ungaqinisekisa ukuthembeka kanye nobude bemigqa yakho yamanzi engaphansi komhlaba, okukunikeza ukuthula kwengqondo kanye nokuzethemba ohlelweni lwakho lwamanzi.
