    Spiral seam ibhola ipayipi lamapayipi amanzi angaphansi komhlaba

    Kuvunguza ipayipi lensimbi lamapayipi amanzi angaphansi komhlaba
    • Spiral seam ibhola ipayipi lamapayipi amanzi angaphansi komhlaba

    Incazelo emfushane:

    Kwethulwa KwethuKuvunguza ipayipi Ngamapayipi amanzi angaphansi komhlaba. Ingqalasizinda yalokhu okusha yipayipi lomshini kaSuluphal, oshisiwe ngokusebenza kahle kusetshenziswa ubuchwepheshe obuphakeme kakhulu be-welding welding emakethe.

    Le khasiIpayipi lamanzi elingaphansi komhlabaIngabe ipayipi lensimbi eliluhlaza elenziwe ngenqubo yokufaka i-aup-wire-wire ephakathi ne-arc. Ipayipi lenziwa kusuka kumakhoyili wensimbi ye-strip futhi likhishwe emazingeni okushisa ahlala njalo ukuze aqinisekise ukuqina kwawo nokuphila isikhathi eside.

    Ukwakhiwa kokwakhiwa okuhlangene kwamapayipi kuqinisekisa ukuthi kuqine kakhulu futhi kuvimbela ingcindezi, okwenza kube yikhethelo eliphelele lezinhlelo zamanzi ezingaphansi komhlaba.

    Ngaphezu kwamandla nokuqina, amapayipi amanzi angaphansi komhlaba aklanyelwe ukufakwa kalula. Ukwakhiwa komthungo okuvuthayo kuyavumelana nezimo futhi kuvumelana nezimo, kuvumela ukuqondisa kalula kanye nokubekwa endaweni eyinselele kakhulu. Lokhu kusho ukuthi ungabeka amapayipi ngokushesha nangendlela efanele, ukonga isikhathi nezindleko zabasebenzi.

    Ngaphezu kwalokho, ukusetshenziswa kwezinto ezisezingeni eliphakeme kanye nobuchwepheshe obuthuthukisiwe be-welding buqinisekisa ukuthi amapayipi amanzi angaphansi komhlaba amelana kakhulu nokugqwala nokugqwala. Lokhu kusho ukuthi kuzogcina ubuqotho bayo nokusebenza kwalo iminyaka, ngisho nasezimweni ezinzima ezingaphansi komhlaba.

    Amapayipi ethu angaphansi komhlaba angaphansi komhlaba ayatholakala ngosayizi abahlukahlukene ukuze bahlangabezane nezidingo ezithile zephrojekthi yakho. Noma ngabe ubeka ukulethwa kwamanzi ekhaya elincane noma uhlelo olukhulu lwezimboni, sinepayipi elifanele wena. Iqembu lethu lochwepheshe linganikeza neseluleko kanye nokusekelwa okuphathelene nokukusiza ukhethe amapayipi ahambisana kangcono nezidingo zakho.

    Uma kukhulunywa ngezinhlelo zamanzi ezingaphansi komhlaba, udinga ipayipi ongalithemba. Ngokwakhiwa okuthuthukile okuhlangene, izinto ezisezingeni eliphakeme kanye nokushiswa kwezinkomba, amapayipi ethu angaphansi komhlaba alungele noma iyiphi inethiwekhi yokuhlinzekwa kwamanzi. Ihlala isikhathi eside, ethembekile futhi okulula ukuyifaka, leli payipi lizovikeleka isikhathi, likunikeze ukuthula kwengqondo nokusebenza okuphezulu.

    Konke kuwo wonke amapayipi e-SHOR SHORE kuwukukhetha okuhle kunoma ngubani odinga isixazululo esezingeni eliphakeme, athembekile, futhi ahlala isikhathi eside. Ngokwakhiwa kwayo okuthuthukile kokwakhiwa kokwakhiwa nokwakhiwainsimbi yensimbi yelding, ipayipi linikeza amandla angenakuqhathaniswa, ukuguquguquka nokumelana nokugqwala. Musa ukuyekethisa ngekhwalithi yohlelo lwakho lwamanzi omhlaba - khetha amapayipi amanzi angaphansi komhlaba njengekhambi ongalithemba.
