Amathubhu amanzi e-PPR, afushane ngokuthi amathubhu e-random copolymer polypropylene, ayizinsimbi ze-polymeric ezenziwe ngohlobo lwe-polypropylene lwezinga lesithathu. Lezi zithubu zihlukaniswa ngokumelana nezinga lokushisa eliphezulu (kuze kube ngu-90℃), ukumelana nengcindezi okuhle, ukuhlanzeka, kanye nezixhumi ezivikelekile zokushisa. Zinegama lokusebenza elingafika eminyakeni engu-50 futhi zisetshenziswa ikakhulukazi ekwakheni ukuhlinzekwa kwamanzi nasekukhishweni kwamanzi, ukuhlinzekwa kwamanzi ezindaweni zasemadolobheni nasemaphandleni, kanye nokunisela kwezolimo. Njengokufaka esikhundleni kwamathubhu e-galvanized, amathubhu amanzi e-UPVC, kanye namathubhu e-aluminium-plastic composite, izinto zawo azinabungozi futhi ziyavikeleka emvelweni futhi zidlule ekuhlolweni kwezimfuneko zendawo [1-2]. Umbala wamathubhu e-PPR unqunywa ngombala owengeziwe. Amathubhu amanzi abandayo namathubhu amanzi ashisayo ahlukaniswa ngemicibisholo eluhlaza/ebomvu kanye nobubanzi bezithubu. Ubuchwepheshe bokuxhuma obushisayo buyasetshenziswa, bukhomba ukusetshenziswa kwamathuluzi akhethekile okushisa nokulawula izinkomba ezifana nesikhathi sokushisa nokujula kokufaka. Ngesikhathi sokwakha, kufanele kugwenywe ukuvuvukala okuphansi. Ukuze kufakwe izinhlelo ezivele zivele noma ezifihlakele, kufanele kufakwe ukwesekwa (ukuhlukaniswa ≤400mm) futhi kuthathwe izinyathelo zokuvikela ukwandiswa. Ebusika, lapho izinga lokushisa lingaphansi kuka-5℃, isikhathi sokushisa sidinga ukwandiswa ngo-50%. Uma kuqhathaniswa namathubhu e-copper kanye namathubhu e-aluminium-plastic composite, amathubhu e-PPR anezinzuzo zentengo efanele kanye nokusebenza okuhle, kodwa izindleko zokufaka ziphakeme futhi izidingo zokwakha ziqinile.
