I-Pn25 Uxinzelelo oluPhezulu 20 – 160 mm UBonelelo lwaManzi ashushu ngaphakathi endlini uMbhobho wePPR oLuhlaza
Imibhobho yePPR inokugcina umgangatho wamanzi okusela ixesha elide.Ayixhathisi nje kuphela kwi-corrosion, kodwa iphinda ichaphazele neekhemikhali ngezinto ezisemanzini, zikhuselekile kwaye zisempilweni.Ngokusebenzisa ulawulo lwethu lweziko, kudityaniswe nemibhobho engama-450 eyahlukeneyo kunye nokufakelwa, ukusuka kwi-20 ukuya kwi-110 mm, iqinisekisa ukufakela okukhuselekileyo nokulula ukuqinisekisa umgangatho ophezulu wamanzi.

1. Uxhulumaniso olungathintelekiyo kunye nokufakwa kwePPR
2. Thintela i-oksijini ekungeneni nasekukhuseleni ukubola, kwaye musa ukuphendula ngezinto ezisemanzini
3. Ukumelana nokushisa okuphezulu, ukumelana nokuguga kunye nobomi benkonzo ende
4. Ukuchasana kwemibhobho kuncinci, akulula ukukala
