    Isingeniso Somkhiqizo

    Sethula amapayipi ethu amanzi ayinhloko asebenza kahle kakhulu, aklanyelwe ukuhlangabezana nezidingo ezahlukahlukene zezimboni eziningi. Yakhiqizwa efektri yethu yesimanje eCangzhou, eSifundazweni saseHebei, inkampani yethu ibilokhu ihola ekukhiqizweni kwamapayipi selokhu yasungulwa ngo-1993. Njengoba inendawo engamamitha-skwele angu-350,000 kanye nempahla iyonke engu-RMB 680 million, siyaziqhenya ngokuba nabasebenzi abazinikele abangochwepheshe abanamakhono abangu-680.

    Okwethuipayipi lamanzi eliyinhlokozenzelwe ukusebenza kahle kakhulu ezisetshenziswayo ezibalulekile njengezindawo zamanzi nezintambo zikagesi. Siyaqonda ukuthi imininingwane yala mapayipi, okuhlanganisa ama-weld kanye nemiklamo yomthungo ojikelezayo, idlala indima ebalulekile ekusebenzeni kwawo kanye nokuthembeka kwawo. Yingakho sisebenzisa amasu okukhiqiza athuthukile kanye nezinyathelo zokulawula ikhwalithi eziqinile ukuqinisekisa ukuthi amapayipi ethu ahlangabezana nezindinganiso eziphakeme kakhulu embonini.

    Amapayipi ethu amanzi aklanyelwe ukuba asebenzeke kahle futhi abe nokuguquguquka okuningi, futhi angasetshenziswa ezindaweni ezahlukahlukene, okwenza abe afanele kakhulu osonkontileka, omasipala, kanye nezicelo zezimboni. Kungakhathaliseki ukuthi ufaka ipayipi elisha lamanzi noma uthuthukisa umugqa wegesi okhona, amapayipi ethu anikeza ukuqina namandla adingekayo ukuze kuhlangatshezwane nezidingo zanoma yimuphi umsebenzi.

    Inzuzo Yomkhiqizo

    Enye yezinzuzo eziyinhloko zamapayipi amanzi amakhulu ukuthi asebenza kahle kakhulu. Aklanyelwe ukuhlangabezana nezidingo zezindawo ezahlukahlukene, okwenza afaneleke kokubili ezindaweni zasemadolobheni nezasemakhaya. Ukuguquguquka kwala mapayipi kuvumela ukuthi asetshenziswe ezinhlotsheni ezahlukene, kusukela ekuhlinzekweni kwamanzi emakhaya kuya ekuthuthweni kwegesi yezimboni. Lokhu kuvumelana nezimo kubalulekile komasipala kanye namabhizinisi ngokufanayo, njengoba kwenza kube lula ukuthengwa nokufakwa kwezinqubo.

    Ukushoda komkhiqizo

    Ukusebenza kwala mapayipi kungathinteka yizici ezifana nezimo zenhlabathi, ukushintshashintsha kwezinga lokushisa, kanye namazinga okucindezela. Isibonelo, amapayipi ahlanganisiwe angase abe sengozini enkulu yokugqwala ezindaweni ezithile, kuyilapho amapayipi omthungo ojikelezayo angase angabi namandla kangako ngaphansi kwezimo zokucindezela okuphezulu. Ukuqonda le mikhawulo kubalulekile konjiniyela nabahleli ukuqinisekisa ukuthi kukhethwa uhlobo olufanele lwepayipi kuzo zonke izinhlelo zokusebenza ezithile.

    Isicelo

    Ukubaluleka kwezindawo zamanzi ezithembekile nezisezingeni eliphezulu ekuthuthukisweni kwengqalasizinda ekhula njalo akunakuphikiswa. Lawa mapayipi aziwa ngokusebenza kahle kwawo, abalulekile ezinhlotsheni ezahlukene zokusebenza, okuhlanganisa amapayipi amanzi negesi. Imininingwane yawo, njengokwelulela kanye nomklamo womthungo ojikelezayo, adlala indima ebalulekile ekuqinisekiseni ukusebenza kahle kanye nokuphila kwenkonzo.

    Amapayipi ethu amanzi ayinhloko asetshenziswa ezinhlotsheni ezahlukene zokusebenza, okubonakala emikhakheni eyahlukene. Kungakhathaliseki ukuthi uhlelo lokuphakelwa kwamanzi lukamasipala noma inethiwekhi yokusabalalisa igesi, amapayipi ethu angamelana nobunzima bokusetshenziswa kwansuku zonke ngenkathi egcina ukusebenza kahle. Ashiselwe futhiipayipi lomthungo ojikelezayoizinketho zinikeza ukuguquguquka kokusetshenziswa, okuvumela izixazululo ukuthi zenziwe ngokwezifiso ukuze zihlangabezane nezidingo ezithile zephrojekthi.

    Imibuzo Evame Ukubuzwa

    Umbuzo 1. Ipayipi lamanzi eliyinhloko lenziwe ngani?

    Amapayipi amakhulu amanzi ngokuvamile enziwa ngezinto eziqinile njengensimbi, i-PVC kanye ne-HDPE. Ukukhetha izinto kuncike ekusetshenzisweni okuthile kanye nezimo zemvelo.

    Umbuzo 2. Ayini amapayipi ahlanganisiwe kanye namapayipi omthungo ojikelezayo?

    Ipayipi elihlanganisiwe lakhiwa ngokuhlanganisa imiphetho emibili yepayipi ndawonye, ​​enesakhiwo esiqinile nesingenawo amanzi. Ipayipi lomthungo ojikelezayo lakhiwa ngokugoqa umucu wensimbi oyisicaba ube yishubhu, onokuguquguquka okukhulu ekuklanyweni nasekusetshenzisweni.

    Umbuzo 3. Ngingayikhetha kanjani ipayipi elifanele iphrojekthi yami?

    Cabangela izici ezifana nohlobo loketshezi oluhanjiswayo, izidingo zokucindezela, kanye nezimo zemvelo. Ukubonisana nochwepheshe kungasiza futhi ukuqinisekisa ukuthi ukhetha ipayipi elifanele izidingo zakho.
