    Izinzuzo zokusebenzisa amapayipi ensimbi afakwe emanzini afakwe emanzini afakwe emanzini angaphansi komhlaba wamapayipi amanzi angaphansi komhlaba

    Izinzuzo zokusebenzisa amapayipi ensimbi afakwe emanzini afakwe emanzini afakwe emanzini angaphansi komhlaba wamapayipi amanzi angaphansi komhlaba afakiwe isithombe
    • Izinzuzo zokusebenzisa amapayipi ensimbi afakwe emanzini afakwe emanzini afakwe emanzini angaphansi komhlaba wamapayipi amanzi angaphansi komhlaba

    Incazelo emfushane:

    Lapho ubeka imigqa yamanzi engaphansi komhlaba, kubalulekile ukukhetha uhlobo olufanele lwepayipi ukuze uqinisekise ukuqina nokuphila isikhathi eside. Ukukhetha okuthandwayo kwemigqa yamanzi engaphansi komhlaba kuyinto ipayipi elivuthayo, elaziwa nangokuthi ipayipi lensimbi ye-Ssaw.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

     Ipayipi lensimbi le-SsawUhlobo lwepayipi elifakwe emanzini aphakathi nendawo eliphakathi nendawo elivame ukusetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi imigqa yamanzi aphansi komhlaba. Inqubo yayo eyingqayizivele ye-Welding ye-Welding ikhiqiza amapayipi amakhulu abubanzi anobubanzi obungaguquki, okwenza kube yinto elungele ukuthuthwa kwamanzi ngaphansi komhlaba.

    Enye yezinzuzo eziphambili zokusebenzisa ipayipi lensimbi elisezingeni eliphansi le-Spiral Inqubo ye-welding ethwele idala ipayipi eliqinile nelithembekile elingamelana nengcindezi nesisindo sokungcwatshwa ngaphansi komhlaba. Lawo mandla abucayi ukuvimbela ukuvuza kanye nokuqinisekisa ubuqotho besikhathi eside samapayipi amanzi.

    Ngokwengeziwe, ipayipi lensimbi ye-SSAW liyamelana nokugqwala, okwenza kube ukukhetha okuhle kwezicelo ezingaphansi komhlaba lapho amapayipi evezwa khona umswakama nezinye izinto zemvelo. Lokhu kumelana nokukhulisa kusiza ukwelula impilo yamapayipi akho futhi kunciphise isidingo sokulungiswa njalo nokulungiswa njalo.

    Ipayipi lomthelela wamanzi angaphansi komhlaba

    Enye inzuzo yokusebenzisa ipayipi lensimbi elisezingeni eliphansi le-WELDC ye-WELDC yensimbi yamanzi aphansi komhlaba ukuguquguquka kwayo nokuvumelana nezimo. Inqubo ye-Welding Cloright ingakhiqiza amapayipi ama-diameter ahlukile, awenze alungele izinhlelo ezahlukahlukene zamapayipi amanzi. Ngokwengeziwe, ukuguquguquka kwe-SSAW Steel Pipe kwenza kube lula ukufaka nokusebenza, ikakhulukazi ezindaweni ezinendawo eyinselele noma izithiyo.

    a. Indlela ye-deoxidation iqokwa kanjena:

    I-FF: Insimbi ebulewe ngokuphelele equkethe izinto ezibophayo ze-nitrogen ngamanani anele ukubopha i-nitrogen etholakalayo (isib

    b. Inani eliphakeme le-nitrogen alisebenzi uma ukwakheka kwamakhemikhali kukhombisa okuqukethwe okuphelele kwe-AL ye-AL ye-0,020% ngesilinganiso esingu-2: 1, noma uma kungenjalo ezinye izinto ezibophayo ze-N zikhona. Izinto ezibophayo ze-N-Bonding zizoqoshwa kudokhumenti lokuhlola.

    Ngaphezu kwamandla, ukuqina, kanye nokuvumelana nezimo, ipayipi lensimbi elisezingeni eliphansi le-WIRC liyabiza kakhulu ngokuqhathaniswa nezinye izinhlobo zepayipi. Inqubo ye-welding eluhlaza inciphisa izindleko zokukhiqiza, okwenza kube inketho yezomnotho eminingi yamaphrojekthi amakhulu wamapayipi amanzi. Ukuqina okuhlala isikhathi eside nezidingo zokulungiswa okuphansi kwepayipi lensimbi ye-SSAW nazo zinomthelela ekugcinweni kwezindleko konke empilweni yomugqa wamanzi.

    Ipayipi le-SSAW

    Sekukonke, kunezindlela eziningi zokusebenzisa ipayipi lensimbi efakwe emanzini afakwe emanzini afakwe emanzini aphansi, kufaka phakathi amandla aphezulu, ukuqina, ukuqina kokugqwala, ukuguquguquka kokungabizi, ukuguquguquka, kanye nokusebenza kahle kwezindleko. Lezi zimfanelo zikwenza kube inketho ethembekile nesebenzayo yokuhamba kwamanzi ngaphansi komhlaba, kungaba ngengqalasizinda kamasipala, izinhlelo zezimboni, noma izinhloso zezolimo.

    Ngokufingqa, uma kukhulunywa ngokukhetha ipayipi elihle kakhuluNgemigqa yamanzi engaphansi komhlaba, Kuvunguza ipayipi yensimbi efakwe ngaphakathi engenisiwe iyisinqumo esihle kunazo zonke. Ukwakhiwa kwalo okuvuthiwe kuhlinzeka ngamandla, ukuqina kanye nokumelana nokugqwala okudingekayo ekusebenzeni isikhathi eside, kanti ukuguquguquka kwayo nokusebenza izindleko kwenza kube inketho ekhangayo yamaphrojekthi wamapayipi amanzi awo wonke amaphrojekthi wamapayipi wamanzi. Ngokukhetha ipayipi lensimbi efakwe emzimbeni ye-WELDC, ungaqinisekisa ukuthembeka nokuphila isikhathi eside kwemigqa yamanzi engaphansi komhlaba, ukukunikeza ukuthula kwengqondo nokuzethemba ohlelweni lwakho lwamanzi.
