Ama-pipe e-PPR, afushane ngokuthi ama-pipe e-random copolymer polypropylene, ayizinsimbi ze-polymeric ezenziwe ngohlobo III polypropylene. Lezi zinsimbi 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 ikakhulu ekwakheni ukuhlinzekwa kwamanzi nasekukhishweni kwamanzi, ukuhlinzekwa kwamanzi emadolobheni nasemaphandleni, kanye nokufakwa kwamanzi kwezolimo. Njengokufaka esikhundleni sama-pipe e-galvanized, ama-pipe e-UPVC, kanye nama-pipe e-aluminium-plastic composite, izinto zawo azinabungozi futhi ziyavikelwa emvelweni futhi zidlule ekuhlolweni kweziqondiso zendawo [1-2]. Umbala wama-pipe e-PPR unqunywa ngombala owengeziwe. Ama-pipe amanzi abandayo nama-pipe amanzi ashisayo ahlukaniswa ngemicibisholo eluhlaza/ebomvu kanye nobukhulu bendawo ye-pipe. Ubuchwepheshe bokuxhuma obushisayo busetshenziswa, bukhomba ukusetshenziswa kwezinsiza ezikhethekile zokushisa nokulawula izimo ezifana nesikhathi sokushisa nobunzima bokufaka. Ngesikhathi sokwakha, kufanele kugwenywe ukuvuvukala okuphansi. Ukuze kufakwe izinsiza 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 ngama-50%. Uma kuqhathaniswa nama-pipe e-copper kanye nama-pipe e-aluminium-plastic composite, ama-pipe e-PPR anenzuzo yokuthi intengo iyaphakathi futhi ukusebenza kuhle, kodwa izindleko zokufaka ziphakeme futhi izidingo zokwakha ziqinile.
