Njengamanje, ohlelweni lwamapayipi okuhambisa amanzi kanye ne-drainage, amapayipi epulasitiki kancane kancane asethathe indawo yamapayipi endabuko njengamapayipi ensimbi namapayipi ensimbi futhi aba amapayipi ajwayelekile.Uma kuqhathaniswa namapayipi endabuko, amapayipi epulasitiki anezinzuzo ezibalulekile ezifana nesisindo esincane, ukumelana nokugqwala, ukumelana nokugeleza kwamanzi okuphansi, ukonga amandla, ukufakwa okulula nokusheshayo, kanye nezindleko eziphansi, futhi athandwa umphakathi wobunjiniyela bamapayipi.Ngesikhathi esifanayo, ngokuthuthuka okusheshayo kwemboni ye-petrochemical kanye nenqubekelaphambili eqhubekayo yobuchwepheshe bokukhiqiza ipulasitiki, ukukhishwa kwamapayipi epulasitiki kuye kwanda ngokushesha, futhi izinhlobo zemikhiqizo ziye zahlukahluka kakhulu.Ngaphezu kwalokho, amapayipi epulasitiki azuze intuthuko enkulu kanye nokwenza ngcono kwethiyori yokuklama kanye nobuchwepheshe bokwakha ekwakheni, futhi aqongelela isipiliyoni esiwusizo esicebile, esikhuthaze amapayipi epulasitiki ukuba athathe isikhundla esibaluleke kakhulu ekwakheni ukuhlinzekwa kwamanzi kanye nobunjiniyela bamapayipi okukhipha amanzi, futhi bakhe intuthuko engenakuvinjelwa. umkhuba.
E-China, iningi lamapayipi epulasitiki asetshenziswa emapayipini okuhambisa amanzi ikakhulukazi ahlanganisa amapayipi okuhambisa amanzi e-PVC-U, amapayipi e-PP-R, amapayipi ayinhlanganisela ye-aluminium-plastic (PAP), amapayipi ayinhlanganisela yensimbi-plastic (SP), amapayipi we-HDPE, njll. Ipayipi le-HDPE livele kuphela emakethe eminyakeni engamashumi amabili edlule.Yamukela ubuchwepheshe obuthuthukisiwe bokukhiqiza kanye nobuchwepheshe futhi yakhiwe nge-extrusion eshisayo.Inezici zokumelana nokugqwala, udonga lwangaphakathi olubushelelezi, ukumelana nokugeleza okuphansi, amandla aphezulu, ukuqina okuhle nesisindo esincane.
Ngemuva kwepayipi lokuphakela amanzi le-PVC-U, ipayipi le-HDPE seliphenduke isibili ezinhlobonhlobo zamapayipi epulasitiki asetshenziswa kakhulu emhlabeni.Njengamanje, amapayipi e-polyethylene aphakathi nendawo noma aphezulu ebanga le-PE80 ne-PE100 kufanele asetshenziselwe ukudluliswa kwegesi;amapayipi e-polyethylene aphakathi nendawo noma aphezulu ebanga le-PE80 kanye ne-PE100 avame ukusetshenziselwa amapayipi okuhambisa amanzi, futhi i-PE63 iye yaqedwa kancane kancane.Mayelana nokulethwa kwamanzi, olukhula ngokushesha uhlelo lwamapayipi e-PE100, okulindeleke ukuthi lukhule ngaphezu kuka-10% eminyakeni emihlanu ezayo.
