Amathube amanzi e-PPR, afushane ngokuthi amathube e-random copolymer polypropylene, ayizinsimbi ze-polymeric ezenziwe ngohlobo III polypropylene. La mathube ahlukaniswa ngokumelana nezinga lokushisa eliphezulu (kuze kube ku-90℃), ukumelana nengcindezi okuhle, ukuhlanzeka, kanye nezixhumi ezivikelekile zokushisa. Anempilo yokusebenza engafika eminyakeni engu-50 futhi asetshenziswa ikakhulukazi ekwakheni ukuhlinzekwa kwamanzi nokukhipha amanzi, ukuhlinzekwa kwamanzi ezindaweni zasemadolobheni nasemaphandleni, kanye nokunisela kwezolimo. Njengokufaka esikhundleni kwamathube agaywe, amathube amanzi e-UPVC, kanye namathube e-aluminium-plastic composite, izinto zawo azinabungozi futhi ziyavumelana nemvelo futhi zidlule ekuqinisekisweni kwezimiso zikazwelonke [1-2]. Umbala wamathube e-PPR unqunywa ngombala owengeziwe. Amathube amanzi abandayo namathube amanzi ashisayo ahlukaniswa ngemicibisholo eluhlaza/ebomvu kanye nobukhulu bezindonga zamathube. Ubuchwepheshe bokuxhuma obushisayo buyasetshenziswa, bukhomba ukusetshenziswa kwezinsiza ezikhethekile zokushisa nokulawula izinkomba ezifana nesikhathi sokushisa nobukhulu bokufaka. Ngesikhathi sokwakha, kufanele kugwenywe ukuvuvukala okuphansi. Ukuze kufakwe izinsiza ezivele zivele noma ezifihlakele, kufanele kufakwe ukwesekwa (ukuphuma ≤400mm) futhi kuthathwe izinyathelo zokuvikela ukwandiswa. Ebusika, lapho izinga lokushisa lingaphansi kuka-5℃, isikhathi sokushisa sidinga ukwandiswa ngama-50%. Uma kuqhathaniswa namathube e-copper kanye namathube e-aluminium-plastic composite, amathube e-PPR anenzuzo yokuba nenani eliphakathi nendawo kanye nokusebenza okuhle, kodwa izindleko zokufaka ziphakeme futhi izidingo zokwakha ziqinile.
