1. Qonda ipayipi lensimbi yekhabhoni elihlanganisiwe eliyindilinga:

Ipayipi lensimbi yekhabhoni elihlanganisiwe elihlanganisiweYakhiwe ngendlela ejikelezayo futhi ihlanganiswe ngamakhoyili ensimbi. Inqubo yokukhiqiza eyingqayizivele yenza la mapayipi aqine futhi aqine kakhudlwana, akwazi ukumelana nokucindezeleka okuphezulu kwangaphakathi nangaphandle. Amandla okumelana nokugqwala nokuguquka kwesimo ayenza ifaneleke kakhulu ezinhlotsheni eziningi zezicelo, okuhlanganisa amapayipi amanzi kanye nokushiselwa kwamapayipi ensimbi.

2. Amapayipi omugqa wamanzi:

Ezinhlelweni zokusatshalaliswa kwamanzi, ukulethwa kwamanzi ahlanzekile okuphephile nokusebenzayo kubalulekile. Ipayipi lensimbi yekhabhoni elihlanganisiwe elihlanganisiwe liye labonakala liyindlela ethembekile yamapayipi amanzi ngenxa yezakhiwo zalo ezingagqwali. Ubuso obubushelelezi bala mapayipi bunciphisa ukungqubuzana, buqinisekisa ukugeleza kwamanzi njalo futhi bunciphise ukuxokozela. Ngaphezu kwalokho, amandla angaphakathi nokuqina kuqinisekisa ukuvikelwa ekuvuvukeni, ukuphuka, kanye nokwehluleka kwesakhiwo, okuqinisekisa ukuhlinzekwa kwamanzi okuqhubekayo nokuthembekile.

3. Ukushisela amapayipi ensimbi:

Imboni yokushisela ithembele kakhulu epayipini lensimbi yekhabhoni elihlanganisiwe elihlanganisiwe elihlanganisiwe elinomoya ukuze kusetshenziswe izinhlobo ezahlukene zezicelo. Amandla angavamile kanye nokuguquguquka kwala mapayipi kwenza abe ngcono kakhulu ekushiseleni amapayipi ensimbi. Kungakhathaliseki ukuthi kwakhiwe amathangi amakhulu okugcina izinto, amapayipi okuthutha uwoyela negesi, noma izingxenye zesakhiwo ezindaweni zezimboni, amapayipi ensimbi yekhabhoni ahlanganisiwe adlala indima ebalulekile. Ukufana kwamajoyinti ahlanganisiwe kuqinisekisa ukuthembeka nokuphepha kwesakhiwo, kunciphisa isidingo sokulungiswa noma ukulungiswa njalo.

4. Izinzuzo nezinzuzo:

4.1 Isixazululo esingabizi kakhulu: Ipayipi lensimbi yekhabhoni elihlanganisiwe elihlanganisiwe linikeza isisombululo esingabizi kakhulu sokushisela amapayipi amanzi kanye namapayipi ensimbi. Ukuqina kwawo kanye nokumelana nokugqwala kuqinisekisa impilo yesevisi ende, ngaleyo ndlela kunciphisa izindleko zokufaka esikhundleni kanye nokulungisa.

4.2 Kulula ukuyifaka: Ubuchwepheshe bokushisela obujikelezayo obusetshenziswa enqubweni yokukhiqiza bungakhiqiza amapayipi amade futhi aqhubekayo, kuncishiswe isidingo samalunga avamile. Lo mklamo olula wenza inqubo yokufaka ibe lula, wonge isikhathi nomzamo.

4.3 Ukuguquguquka: Amapayipi ensimbi yekhabhoni ahlanganisiwe nge-Spiral atholakala ngobubanzi nobukhulu obuhlukahlukene, okuvumela ukuthi avumelane nezinhlelo zokusebenza ezahlukene. Angenziwa ngokwezifiso ukuze ahlangabezane nezidingo ezithile zephrojekthi, avumelane noketshezi oluhlukahlukene, ukucindezela kanye namazinga okushisa ahlukahlukene.

4.4 Ukuvikelwa kwemvelo: Insimbi yekhabhoni iyinto ephinde isetshenziswe enegalelo ekusimeni kwemvelo. Amapayipi ensimbi yekhabhoni ahlanganisiwe ajikelezayo angaphinde asetshenziswe futhi, kuncishiswe imfucuza futhi kuvikelwe imithombo yemvelo.

Ekuphetheni:

Amakhono kanye nezinzuzo zamapayipi ensimbi yekhabhoni ahlanganisiwe ajikelezayo epayipini lamanzi kanyeukushisela ipayipi lensimbiAkunakuthathwa kalula. Ukudluliselwa kwamanzi noketshezi lwezimboni okusebenzayo nokuthembekile kuncike kakhulu ekuqineni kwawo, ukumelana nokugqwala kanye nokulula kokufakwa. Njengoba isidingo sengqalasizinda eqinile nengabizi siqhubeka nokukhula, amapayipi ensimbi yekhabhoni ahlanganisiwe nge-spiral azohlala eyisici esibalulekile ekuqinisekiseni ukusebenza kahle kwezinhlelo zamanzi nezinqubo zezimboni emhlabeni jikelele.
