    Imigqa Yegesi Engaphansi Komhlaba – Ipayipi Lensimbi le-X65 SSAW

    Imigqa Yegesi Engaphansi Komhlaba – Ipayipi Lensimbi le-X65 SSAW Isithombe Esivelele
    • Imigqa Yegesi Engaphansi Komhlaba – Ipayipi Lensimbi le-X65 SSAW

    Incazelo emfushane:

    Sethula ipayipi lethu lensimbi le-SSAW elisha, umkhiqizo wekhwalithi ephezulu owenzelwe izinhlelo zokusebenza ezahlukahlukene, ikakhulukazi amapayipi egesi yemvelo angaphansi komhlaba. Leli payipi lomugqa we-X65 SSAW lisetshenziswa kabanzi ekushiseleni amapayipi okuthutha uketshezi, izakhiwo zensimbi, izisekelo zezinqwaba, njll. Ngenxa yokusebenza kwalo okuphezulu nokuqina kwalo, lo mkhiqizo ubhekwa njengobalulekile ezimbonini ezahlukahlukene kanye namaphrojekthi engqalasizinda.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Ipayipi elihlanganisiwe elihlanganisiwe elihlanganiswe nge-spiral liyingxenye ebalulekile yobunjiniyela bokuphakelwa kwamanzi, imboni yamakhemikhali kaphethiloli, imboni yamakhemikhali, imboni yamandla kagesi, ukunisela kwezolimo, kanye nokwakhiwa kwamadolobha. Ukuguquguquka kwalo kanye nokuthembeka kwalo kuye kwalenza laba ngomunye wemikhiqizo engamashumi amabili ebalulekile ethuthukiswe ezweni lethu, okubonisa ukubaluleka kwalo kanye nomthelela walo ezimbonini ezahlukahlukene.

    Ipayipi lensimbi le-SSAWYenzelwe ukuthuthwa koketshezi futhi ifaneleka kakhulu ezinhlelweni zokuphakelwa kwamanzi kanye nokukhipha amanzi. Ukwakhiwa kwayo okuqinile kwenza kube kuhle kakhulu ukuqinisekisa ukudluliswa koketshezi okusebenzayo nokuthembekile. Ngaphezu kwalokho, ifaneleka futhi ekuthuthweni kwegesi njengegesi yamalahle, umusi, kanye negesi kaphethiloli encibilikisiwe. Amandla ayo aphezulu okudonseka kanye nokumelana nokugqwala kuqinisekisa ukulethwa kwegesi okuphephile nokuphumelelayo futhi kuhlangabezana nezidingo eziqinile zezinhlelo zokulethwa kwegesi.

    Enye yezinhlelo zokusebenza eziyinhloko zamapayipi ethu ensimbi ahlanganiswe nge-spiral arc acwiliswe yi-umugqa wegesi ongaphansi komhlabaNgenxa yekhwalithi yayo ephezulu kanye nokusebenza kwayo, iyisinqumo sokuqala sokwakha amanethiwekhi okuthutha igesi yemvelo athembekile futhi aphephile.

    Ipayipi Lamanzi Elingaphansi Komhlaba

    Ipayipi lomugqa we-X65 SSAWYakhiwe ngezinto ezisezingeni eliphezulu eziqinisekisa amandla aphezulu nokuqina. Lokhu kuyenza ifaneleke kakhulu ekusetshenzisweni okudinga umfutho ophezulu kanye nokumelana nezimo zemvelo. Ukufaneleka kwayo ekufakweni komhlaba kugcizelela kakhulu ukwakheka kwayo okuqinile kanye nekhono lokubekezelela izimo ezinzima, okwenza kube yisisombululo esikhethwayo samaphrojekthi okuhambisa igesi ngaphansi komhlaba.

    Njengomkhiqizo othembekile noqinisekisiwe, amapayipi ethu ensimbi ahlanganiswe nge-spiral ac welded arc asetshenziswa kabanzi kuzo zonke izimboni kanye namaphrojekthi engqalasizinda ngenxa yokusebenza kwawo okuphezulu, ukuqina kanye nokuthembeka. Ukwakhiwa kwawo kwekhwalithi ephezulu kwenza kube ukukhetha kokuqala kwezinhlelo zokuthutha uketshezi kanye negesi, ikakhulukazi emgqeni wegesi ongaphansi komhlaba lapho ukuphepha nokusebenza kahle kubalulekile khona.

    Ngamafuphi, ipayipi lensimbi elihlanganisiwe elihlanganiswe nge-spiral submarine arc liwumkhiqizo omuhle kakhulu owenzelwe ukuhlangabezana nezidingo ezahlukahlukene zezinhlelo zokulethwa koketshezi negesi. Ngenxa yokuguquguquka nokuthembeka kwalo, seliyingxenye ebalulekile emikhakheni eyahlukene kanye namaphrojekthi engqalasizinda, ikakhulukazi umugqa wegesi ongaphansi komhlaba. Ikhwalithi yalo eyingqayizivele kanye nokusebenza kwalo kuyenza ibe yimpahla ebalulekile ekuqinisekiseni inethiwekhi yokuthutha igesi esebenza kahle futhi ephephile. Themba ukuthembeka nokusebenza kwamapayipi ethu ensimbi ahlanganisiwe ahlanganiswe nge-spiral submarine kuzo zonke izidingo zakho zokuthutha uketshezi negesi.
