    Ipayipi Lensimbi Yomthungo Ojikelezayo Yamapayipi Amanzi Angaphansi Komhlaba

    Ipayipi Lensimbi Yomthungo Ojikelezayo Yamapayipi Amanzi Angaphansi Komhlaba Isithombe Esifakiwe
    • Ipayipi Lensimbi Yomthungo Ojikelezayo Yamapayipi Amanzi Angaphansi Komhlaba

    Incazelo emfushane:

    Sethulaipayipi lomthungo ojikelezayo yamapayipi amanzi angaphansi komhlaba. Ingqalasizinda yalolu shintsho ipayipi lomthungo elijikelezayo, elishiselwe ngobungcweti kusetshenziswa ubuchwepheshe bokushisela amapayipi ensimbi obusezingeni eliphezulu emakethe.

    Iipayipi lamanzi elingaphansi komhlabaiyipayipi lensimbi elijikelezayo elenziwe ngenqubo yokuwelda ye-arc engaphansi kwamanzi enama-double-wire double sides. Leli payipi lenziwe ngama-strip steel coils futhi likhishwa ekushiseni okulinganayo ukuqinisekisa ukuqina kwalo kanye nobude balo.

    Ukwakhiwa kwepayipi elihlanganisiwe kuqinisekisa ukuthi liqinile kakhulu futhi alicindezeleki, okwenza libe ukukhetha okuhle kakhulu kwezinhlelo zamanzi angaphansi komhlaba.

    Ngaphezu kokuqina nokuqina, amapayipi amanzi angaphansi komhlaba aklanyelwe ukufakwa kalula. Ukwakhiwa komthungo ojikelezayo kuyaguquguquka futhi kuyavumelana nezimo, okuvumela ukushelela nokubeka amapayipi kalula ngisho nasendaweni enzima kakhulu. Lokhu kusho ukuthi ungawabeka ngokushesha nangokusebenza kahle amapayipi, wonge isikhathi nezindleko zabasebenzi.

    Ngaphezu kwalokho, ukusetshenziswa kwezinto ezisezingeni eliphezulu kanye nobuchwepheshe bokushisela obuthuthukisiwe kuqinisekisa ukuthi amapayipi amanzi angaphansi komhlaba amelana kakhulu nokugqwala nokugqwala. Lokhu kusho ukuthi izogcina ubuqotho bayo nokusebenza kwayo iminyaka eminingi, ngisho nasezimweni ezinzima zangaphansi komhlaba.

    Izinqubo Zokushisela Amapayipi
    Ipayipi elinophahla lwe-polyurethane

    Amapayipi ethu amanzi angaphansi komhlaba atholakala ngobukhulu obuhlukahlukene ukuze ahlangabezane nezidingo ezithile zephrojekthi yakho. Kungakhathaliseki ukuthi ubeka amanzi amancane asekhaya noma uhlelo olukhulu lwezimboni, sinepayipi elifanele wena. Ithimba lethu lochwepheshe lingakunikeza neseluleko kanye nokusekelwa okuklanyelwe wena ukuze kukusize ukhethe amapayipi afanelana kahle nezidingo zakho.

    Uma kukhulunywa ngezinhlelo zamanzi angaphansi komhlaba, udinga ipayipi ongayethemba. Ngokwakhiwa okuthuthukisiwe kwe-spiral joint, izinto ezisezingeni eliphezulu kanye nokushisela kochwepheshe, amapayipi ethu amanzi angaphansi komhlaba afanelekela noma iyiphi inethiwekhi yokuphakelwa kwamanzi. Ihlala isikhathi eside, ithembekile futhi kulula ukuyifaka, le payipi izokuma isikhathi eside, ikunike ukuthula kwengqondo nokusebenza okuhle kakhulu.

    Sekukonke, amapayipi omthungo ojikelezayo ayisinqumo esihle kakhulu kunoma ubani odinga isisombululo sokusabalalisa amanzi esisezingeni eliphezulu, esithembekile, nesihlala isikhathi eside. Ngokwakhiwa kwawo komthungo ojikelezayo okuthuthukisiwe kanye nobungcweti.ukushisela ipayipi lensimbi, ipayipi linikeza amandla angenakuqhathaniswa, ukuguquguquka kanye nokumelana nokugqwala. Ungalinciphisi ikhwalithi yesistimu yakho yamanzi angaphansi komhlaba – khetha amapayipi amanzi angaphansi komhlaba njengesixazululo ongasithemba.
