    Ipayipi eliphambili lamanzi elinokusebenza okuphezulu

    Ipayipi eliphambili lamanzi elinezicelo eziphezulu ezifakiwe
    • Ipayipi eliphambili lamanzi elinokusebenza okuphezulu

    Incazelo emfushane:

    Ama-main yethu wamanzi aklanyelwe ukuba asebenze kakhulu futhi aguquguqukayo, futhi angasetshenziswa ezindaweni ezahlukahlukene, abenze balungele osonkontileka, omasipala kanye nezicelo zezimboni.

    Isingeniso Somkhiqizo

    Kwethulwa amapayipi ethu aphambili aphezulu we-Serviceabity, enzelwe ukufeza izidingo ezahlukahlukene ezahlukahlukene zezimboni. Kukhiqizwe efektri yethu yombuso eFetgzhou, eSifundazweni seHebei, inkampani yethu ibilokhu ingumholi ebholeni lamapayipi selokhu kwasungulwa ngo-1993. Ngempahla yamamitha-skwele angama-350, thina bayaziqhenya ngokuba nabasebenzi abazinikele kochwepheshe abanamakhono angama-680.

    -KwethuIpayipi lamanzi eliphambilibanenjinizo yokusebenza kahle kwezicelo ezibucayi ezifana nama-main mains kanye nemigqa yegesi. Siyaqonda ukuthi imininingwane yalamapayipi, kufaka phakathi ama-welds kanye nemiklamo ye-spiral seam, dlala indima ebalulekile ekusebenzeni kwawo nokwethembeka. Kungakho sisebenzisa amasu okukhiqiza athuthukile nezindlela zokulawula ezisezingeni elifanele zokuqinisekisa amapayipi ethu ahlangabezana namazinga aphezulu embonini.

    Ama-main yethu wamanzi aklanyelwe ukuba asebenze kakhulu futhi aguquguqukayo, futhi angasetshenziswa ezindaweni ezahlukahlukene, abenze balungele osonkontileka, omasipala kanye nezicelo zezimboni. Noma ngabe ufaka imali entsha yamanzi noma uthuthukise umugqa wegesi okhona, amapayipi ethu anikela ngokuqina namandla adingekayo ukuze ahlangabezane nezidingo zanoma yimuphi umsebenzi.

    Inzuzo yomkhiqizo

    Enye yezinzuzo eziyinhloko zamapayipi amanzi aphambili ukuphathwa kwawo okuphezulu. Zenzelwe ukufeza izimfuno zezindawo ezahlukahlukene, zibenze balungele zombili izilungiselelo zasemadolobheni nezasemakhaya. Ukuguquguquka okuhlukahlukene kwalawa mapayipi kuyabavumela ukuthi basetshenziswe ezinhlelweni ezihlukile, kusuka ekuhlinzekeni kwamanzi ezindaweni zokuhlala ezimbonini. Lokhu kuvumelana nezimo kubalulekile komasipala namabhizinisi ngokufanayo, njengoba kwenza lula ukuthengiswa kanye nezinqubo zokufaka.

    Ukushiyeka komkhiqizo

    Ukusebenza kwalawa mapayipi kungathintwa yizinto ezinjengezimo zenhlabathi, ukuguquguquka kwezinga lokushisa, namazinga wokucindezela. Isibonelo, amapayipi we-welded angaba khona ekugculiseni ngokwengeziwe ezindaweni ezithile, kanti amapayipi e-Spiral Seam kungenzeka angabi namandla ngaphansi kwezimo eziphakeme kakhulu. Ukuqonda lokhu kulinganiselwa kubalulekile kunjiniyela kanye nabahleli bokuqinisekisa ukuthi uhlobo lwepayipi olufanele lukhethiwe isicelo ngasinye.

    Isicelo

    Ukubaluleka kwe-Manzi Esezingeni Eliphezulu Esezingeni eliphakeme ekuthuthukisweni kwengqalasizinda ekhulayo akunakweqiwa. Yaziwa nge-serviceality yazo ephezulu, la mapayipi abalulekile ezinhlobonhlobo zezicelo, kufaka phakathi amapayipi amanzi namagesi. Ukucaciswa kwabo, njenge-welds kanye ne-spiral seam design, dlala indima ebalulekile ekuqinisekiseni ukusebenza kahle kanye nempilo yenkonzo.

    Amapayipi ethu asemqoka asemqoka asetshenziswa ezinhlobonhlobo zezicelo, eziboniswa ezinhlobonhlobo zamasimu. Noma ngabe uhlelo lokuhlinzekwa kwamanzi kamasipala noma inethiwekhi yokusabalalisa igesi, amapayipi ethu angamelana nobunzima bokusetshenziswa kwansuku zonke ngenkathi egcina ukusebenza kahle. I-welded futhiKuvunguza ipayipiIzinketho zinikeza ukuguquguquka kwesicelo, okuvumela izixazululo ukuthi zenziwe ngezifiso ukufeza izidingo ezithile zephrojekthi.

    Umthandi

    Q1. Yikuphi okubonakalayo ipayipi lamanzi eliphambili elenziwe?

    Ama-main mains ajwayele ukwenziwa ngezinto eziqinile ezifana nensimbi, i-PVC ne-HDPE. Ukukhethwa kokuqukethwe kuncike ohlelweni oluthile kanye nezimo zemvelo.

    Q2. Yimaphi amapayipi we-welded kanye namapayipi we-siam?

    Ipayipi le-welded yakhiwa ngokujoyina imiphetho emibili yepayipi ndawonye, ​​elinesakhiwo esinamandla nesivuzayo. Kuvunguza ipayipi le-Spiral Spiral ngokwakhiwa ngokugoqa umucu wensimbi ofuphezelayo esimweni seshubhu, enokuguquguquka okuthe xaxa ekwakhekeni nasekusetshenzisweni.

    Q3. Ngiyikhetha kanjani ipayipi elifanele kwiphrojekthi yami?

    Cabanga ngezinto ezifana nohlobo loketshezi oludluliswa, izidingo zokucindezela, kanye nezimo zemvelo. Ukubonisana nochwepheshe nakho kungasiza ekuqinisekiseni ukuthi ukhetha ishubhu elihle kakhulu ngezidingo zakho.
