Sethula amapayipi ethu okunqwabelanisa: isixazululo sezidingo zakho zesisekelo

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Eminyakeni yamuva nje, isidingo sokunqwabelanisa amapayipi ensimbi ezimbonini ezihlukahlukene sikhule kakhulu.Ngokukhula okusheshayo kokwakhiwa nokuthuthukiswa kwengqalasizinda, ububanzi be ukunqwabelanisa ipayipiliya liba likhulu futhi libe likhulu.Ngakho-ke, isidingo sekhwalithi ephezulu Kuvunguza ashiselwe ezinkulu ububanzi steel ipayipi izinqwaba kuba esibucayi.

Enkampanini yethu, siye sabona lesi sidingo esikhulayo futhi sakha isixazululo esiphezulu sokuhlangabezana nezidingo zemakethe - izinqwaba zethu ezinkulu zamapayipi ensimbi.Lawa mapayipi anqwabelene aklanyelwe ukuhlinzeka ngomthamo wokuqala wokuthwala umthwalo wamatheminali amanzi ajulile, okuwenza abe yingxenye ebalulekile yanoma iyiphi iphrojekthi yokwakha yasolwandle.
