Ndi chitukuko chofulumira chachuma, anthu akupita patsogolo.M'madera ambiri monga ulimi wamakampani ndi migodi, kutulutsa madzi oipa ndi zimbudzi mumayendedwe akuluakulu a mapaipi amtundu wa mapaipi, mtundu wanji wa mapaipi oti agwiritse ntchito ndi zipangizo zomwe zingagwiritsidwe ntchito zagwirizana ndi mabungwe akuluakulu a kafukufuku ku China.Mapaipi a HDPE, ndi magwiridwe ake apamwamba, asintha pang'onopang'ono mapaipi am'mbuyomu a simenti ndi chitsulo.Mapaipi akale awa okhala ndi zochitika zotsika pang'onopang'ono adazimiririka pamsika ndikupita patsogolo kwa modornization.Mapaipi a HDPE amakhala ndi moyo wautali wautumiki, ukhondo wabwino, samakulitsa, samasunga mabakiteriya, amalimbana ndi mankhwala osiyanasiyana, amakhala ndi khoma lamkati losalala, kukana kuvala bwino, kukana kukhudzidwa, mphamvu yayikulu komanso yosavuta kunyamula ndikuyika.
Mapaipi a HDPE akupezeka m'makalasi 18 okhala ndi ma calibers kuyambira DN16 mpaka DN315.Mapaipi a HDPE adzasungunuka pa kutentha kwa 190 ° C-240 ° C.Pogwiritsa ntchito mbaliyi, gawo losungunuka la chitoliro (kapena zopangira zitoliro) lidzalumikizidwa mokwanira ndikusungidwa pansi pa kupanikizika koyenera, ndipo ziwirizo zikhoza kuphatikizidwa pamodzi pambuyo pozizira.Malinga ndi kukula kwa chitoliro, akhoza kugawidwa motere: pamene DN≤63, izo utenga jekeseni kuumbidwa otentha Sungunulani zitsulo kugwirizana;pamene DN≥75, imatenga kugwirizana kwazitsulo zotentha zosungunuka kapena kugwirizana kwa socket yamagetsi;ikalumikizana ndi zida zosiyanasiyana, imatengera kulumikizana kwa flange kapena silika.
Mapaipi a HDPE amagwiritsidwa ntchito makamaka pa: makina opangira madzi opangira madzi, makina opangira madzi amkati anyumba, makina operekera madzi okwiriridwa panja ndi kukwiriridwa madzi osungiramo anthu okhalamo ndi mafakitale, kukonza mapaipi akale, makina opangira madzi opangira madzi, mapaipi amadzi am'mafakitale minda, ulimi wothirira ndi minda ina, ndi zina zotero. Komabe, ziyenera kudziwidwa kuti mapaipi a HDPE sangagwiritsidwe ntchito popanga mapaipi a madzi otentha.
Mapaipi amadzi a HDPE amagwiritsidwa ntchito kwambiri, makamaka chifukwa ali ndi zabwino zomwe mapaipi ena sangafanane: 1, kuwotcherera kosavuta komanso kuwotcherera kwa electrofusion ndikupanga njira yotsekeka yotsekeka.Ikaikidwa m'mphepete mwa ngalandeyo, imatha kuchepetsa kukumba ngalande ndikuchepetsanso zopangira.2, kulemera kopepuka komanso kosavuta kukhazikitsa ndikugwira;3, amphamvu kuvala kukana ndi zabwino hayidiroliki katundu, mu payipi m'manda akhoza kukhala popanda wosanjikiza kunja kwa chitetezo.Itha kugwiritsidwa ntchito pa chivomezi ndi migodi kukhazikika m'madera nthaka, ndipo akhoza anaika pansi pa mitsinje ndi njira kumira.4, Kugonjetsedwa ndi dzimbiri mankhwala, mkati, kunja ndi tizilombo ting'onoting'ono dzimbiri, amphamvu dzimbiri kukana ndi thanzi.Oyenera kunyamula zinthu za acidic ndi zamchere, zotengera zimbudzi, gasi, gasi ndi zinthu zina;5. Kusinthika kwabwino kwa chilengedwe komanso kukana chisanu.Angagwiritsidwe ntchito m'nyumba ndi panja madzi mapaipi.6. Moyo wautali wautumiki, ndi moyo wautumiki wa zaka pafupifupi 50.7. Yosavuta kukonzanso ndikugwiritsa ntchito.
