Amathubhu amanzi e-PPR, afushane nge-random copolymer polypropylene pipes, ayizinsimbi ze-polymeric ezenziwe ngohlobo III polypropylene. La mathubhu ahlukaniswa ngokumelana nezinga lokushisa eliphezulu (kuze kube ku-90℃), ukumelana nengcindezi okuhle, ukuhlanzeka, kanye nezixhumi ezivikelekile ezishisayo. Anempilo yokusebenza efika eminyakeni engama-50 futhi asetshenziswa ikakhulukazi ekwakheni ukuhlinzekwa kwamanzi nasekukhishweni, ukuhlinzekwa kwamanzi ezindaweni zasemadolobheni nasemaphandleni, kanye nokunisela kwezolimo. Njengokufaka esikhundleni kwamathubhu agaywe, amathubhu amanzi e-UPVC, kanye namathubhu e-aluminium-plastic composite, izinto zawo azinabungozi futhi zihlala zihlanzekile futhi zidlule ekuhlolweni kwezinga lesizwe [1-2]. Umbala wamathubhu e-PPR unqunywa ngombala owengeziwe. Amathubhu amanzi abandayo namathubhu amanzi ashisayo ahlukaniswa ngemicibisholo eluhlaza/ebomvu kanye nobukhulu bendawo yamathubhu. Ubuchwepheshe bokuxhuma obushisayo busetshenziswa, buhlinzeka ngensiza ethile yokushisa kanye nokulawula izimo ezifana nesikhathi sokushisa kanye nokujula kokufaka. 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 namathubhu e-copper kanye namathubhu e-aluminium-plastic composite, amathubhu e-PPR anenzuzo yokuba nentengo efanele kanye nokusebenza okuhle, kodwa izindleko zokufaka ziphakeme futhi izidingo zokwakha ziqinile.
