1. UKUNIKEZWA KWAMANZI
Amapayipi e-PE enziwe ngezinto ezihlangabezana nemfuneko yobuthi ye-WHO futhi lokhu kungahamba ngebhasi ukuze kuthuthwe amanzi okuphuza. Amapayipi nokufakwa okunezilinganiso zokucindezela kwe-SDR 7.4 kufika ku-SDR 41 kumapayipi amanzi kanye nesistimu yamapayipi okusabalalisa nezintambo zesevisi.
2. IGASI&AMAFUTHA
Amapayipi e-PE okuthutha igesi ngomfutho ophansi ophakathi ayatholakala. Amapayipi aklanywe ngokukhethekile ngobushelelezi futhi enziwe lula ukuyifaka. Imigqa yegesi ingafakwa ezindaweni eziphansi. Ekubhobolweni asetshenziswa njengamagobolondo anemigodi emifushane njengoba eshibhile. Ngenxa yezakhiwo ezinhle kakhulu zepayipi le-HDPE, elibonisa amandla omthelela aphezulu kanye nenhlabathi enhle kakhulu enolaka. Ehlanganiswe nokunikeza nokufaka kalula, amapayipi e-HDPE mahle kakhulu ekuthutheni impahla kanye nezinye izinhlobo zegesi okuhlanganisa ne-bio-gas.
3. UMDLALO&SIPHON
Amapayipi e-PE asetshenziselwa ukudonsa amanzi ngaphansi komhlaba ezakhiweni, izintambo zikadoti zoketshezi olubolayo kanye nanjengempahla yokufaka amapayipi amanzi aphuma endlini. Zingabuye zisetshenziselwe imisebenzi yendle. Ngenxa yokumelana kwayo namakhemikhali okuhle kakhulu, i-HDPE iyinto efanelekile yomkhiqizi wamapayipi amakhulu abhorekile wezinhlelo zokukhucululwa kwendle. Zikulungele kahle ukulahlwa kwemfucuza yezimboni futhi zisetshenziswa ngokwezinga elikhulayo njengamapayipi endle angaphansi komhlaba kanye namapayipi emfucuza.
4. INDUSTRY&CHEMICAL
Izici ezifana nokumelana nokugqwala, ukufakwa kalula, isisindo esilula, nokuguquguquka kwenza amapayipi e-PE afaneleke ezinkingeni ezimbonini, Alungele amakhemikhali abolayo.
5. I-ELECTRICAL&TELECOM
Amapayipi e-PE avunyelwe ukufakwa zonke izinhlobo zenhlabathi. I-polyethylene iyimpahla yamapayipi eguquguqukayo futhi eqinile. Ngakho-ke, lezi zinhlelo zifaneleka ngokukhethekile ukufakwa emhlabathini ongenwa kalula yimpahla yamapayipi aphansi futhi aqinile. Ukusetshenziswa kwezindlela ezahlukahlukene zokuhlanganisa kufaka uhlelo lokuhlinzeka ngobufakazi bokuvuza. Ngenxa yesisindo sokukhanya nezindlela ezilula zokuhlanganisa, amapayipi e-HDPE afaneleka kakhulu izimo ezingezinhle zokufakwa endaweni enzima.
6. UKUNSELELA
Ipayipi lokunisela le-PE wuhlobo lwesistimu yamapayipi okunisela ngezolimo. Ukusebenza kahle kwamapayipi e-PE kwenza uhlelo lokunisela lusebenze kahle, luqinisekise ukuchelela okwanele kuwo wonke amagumbi ensimu nokwenza ngcono isivuno kanye nekhwalithi yezitshalo. Ngokusebenzisa izinhlelo zokuchelela ezonga amanzi ezifana nokuchelela ngokuconsa kanye nokuchelela okuncane, ipayipi le-PE linciphisa ngempumelelo ukuhwamuka kwamanzi nokuvuza. Lokhu kunemithelela ebalulekile ekudambiseni ukushoda kwamanzi. Ipayipi le-PE linempilo ende yesevisi, izindleko zokulungisa eziphansi, futhi linganciphisa isabelomali esiphelele sephrojekthi. Lokhu kuzosiza ekwehliseni umthwalo wezomnotho wabalimi kanye nokwenza ngcono izinzuzo zezomnotho zokukhiqizwa kwezolimo.
7. IZIMALI
Ipayipi lamanzi le-PE lidlala indima ebalulekile embonini yezimayini ngenxa yokumelana kwayo okubandayo, impilo ende yesevisi, ukumelana nokugqwala nezinye izici.
● Ukuthuthwa kwamanzi: Ipayipi lokuhambisa amanzi e-PE ngenxa yokumelana nokugqwala okuhle nokumelana nokugqoka, lingakwazi ukumelana nezinhlobonhlobo zezindawo zezimboni ezinokhahlo, ngakho-ke lisetshenziselwa imayini ukudlulisa uketshezi, njengamanzi, izixazululo zamakhemikhali, njll, ukuze kuqinisekiswe inqubekelaphambili eshelelayo yemisebenzi yezimayini.
● I-Gas drainage: Ipayipi lokuhambisa amanzi le-PE libuye lifanele ukuthuthwa kwegesi, ukuze kuqinisekiswe ukuphepha kwenqubo yezimayini, ukugwema ukunqwabelana kwegesi okubangelwa izingozi zokuphepha.
● Ukuthuthwa kwemisila: Izinsika ezikhiqizwa ohlelweni lwezimayini zidinga ukuthuthwa futhi zilashwe ngamapayipi. Ngenxa yokuqina nokuthembeka kwayo, ipayipi lokuhambisa amanzi le-PE liyinketho efanelekile yokuthutha i-tailings.
8. AMANZI
Ipayipi le-HDPE linezici zokuqina okuphezulu nokumelana nokugqwala, okungakwazi ukuzivumelanisa nezimo ezinzima zemvelo yasolwandle futhi kuqinisekise ukuzinza nokuqina kwehhashi. Indlela ye-hot melt welding yepayipi le-PE yenza uhlaka lohlaka luqine, lungamelana nomthelela womoya namagagasi, futhi luqinisekise ukuphepha kwezinto eziphilayo ezizalayo. Ipayipi le-PE lidlala indima ebalulekile ekujikelezeni kwekhwalithi yamanzi kanye nohlelo lokuhlanza, ukumelana nokugqwala kwalo okuhle nokumelana nokugqoka kwenza ipayipi le-PE libe yisinqumo esihle. Ngokuklama kwesistimu yokusakaza yesayensi nenengqondo, ipayipi le-PE lingakhipha ngokuphumelelayo izinto eziyingozi emanzini e-aquaculture, futhi lethule umthombo wamanzi ahlanzekile noma amanzi ahlanzekile, ligcine izinga lamanzi lihlanzekile futhi lizinzile, lithuthukise ukusebenza kahle kokusetshenziswa kwamanzi, linciphise izinga lezifo .
