Ngokuthuthuka okusheshayo komnotho, umphakathi nawo uyathuthuka.Emikhakheni eminingi efana nezolimo ezithuthukisiwe nezimayini, ukuchithwa kwamanzi angcolile kanye nendle ohlelweni lwamapayipi amakhulu amapayipi kamasipala, hlobo luni lwamapayipi okufanele lusetshenziswe nokuthi yiziphi izinto ezizosetshenziswa kuvunyelwene ngazo yizikhungo ezinkulu zocwaningo eChina.Amapayipi e-HDPE, ngokusebenza kwawo okuphakeme, kancane kancane ashintshile usimende wangaphambili namapayipi ensimbi.Lawa mapayipi ayisidala anezinto eziconsayo anyamalala kancane kancane emakethe ngokuqhubeka kwe-modornization.Amapayipi e-HDPE anokuphila okude kwenkonzo, inhlanzeko enhle, ayilinganisi, awafaki amabhaktheriya, amelana namakhemikhali ahlukahlukene, anodonga lwangaphakathi olubushelelezi, ukumelana nokugqokwa okuhle, ukumelana nomthelela, amandla aphezulu futhi kulula ukuwahambisa nokuwafaka.
Amapayipi e-HDPE atholakala kumabanga ayi-18 anezilinganiso ukusuka ku-DN16 kuya ku-DN315.Amapayipi e-HDPE azoncibilika ezingeni lokushisa elingu-190°C-240°C.Ukusebenzisa lesi sici, ingxenye encibilikisiwe yepayipi (noma ukufakwa kwamapayipi) izothintwa ngokugcwele futhi igcinwe ngaphansi kwengcindezi efanele, futhi lezi ezimbili zingahlanganiswa ngokuqinile ngemva kokupholisa.Ngokusho kobukhulu bepayipi, ingahlukaniswa ngokulandelayo: lapho i-DN≤63, yamukela uxhumano lwesokhethi olubunjiwe olubunjiwe olushisayo;uma i-DN≥75, ithatha uxhumano lwe-hot melt butt noma uxhumano lwesokhethi kagesi;lapho ixhuma ngezinto ezahlukene, isebenzisa i-flange noma i-silika buckle uxhumano.
Amapayipi e-HDPE asetshenziselwa kakhulu: uhlelo lukamasipala lokuhlinzeka ngamanzi ngonjiniyela, uhlelo lokuphakelwa kwamanzi angaphakathi ezakhiweni, uhlelo lokuphakelwa kwamanzi agqitshwe ngaphandle kanye nohlelo lokuphakelwa kwamanzi angcwatshwe emiphakathini yokuhlala namafemu, ukulungiswa kwamapayipi amadala, uhlelo lobunjiniyela bokuhlanza amanzi, amapayipi amanzi ezimboni ukulima, ukuchelela kanye nezinye izinkambu, njll. Kodwa-ke, kufanele kuqashelwe ukuthi amapayipi e-HDPE awakwazi ukusetshenziselwa amapayipi amanzi ashisayo.
Ipayipi lamanzi le-HDPE lisetshenziswa kakhulu, ikakhulukazi ngenxa yokuthi linezinzuzo amanye amapayipi angeke afane nalokhu: 1, ukushisela kalula ngezinqe kanye nokushisela nge-electrofusion futhi yakhe isistimu evaliwe engangenisi eqediwe.Uma ibekwe eduze komsele, inganciphisa inani lokumbiwa komsele futhi inciphise inani lezinto zokufakwa.2, isisindo esincane futhi kulula ukuyifaka nokubamba;I-3, ukumelana nokugqoka okuqinile kanye nezakhiwo ezinhle kakhulu ze-hydraulic, epayipini elingcwatshwe kungaba ngaphandle koqweqwe lwangaphandle lokuvikela.Ingasetshenziswa ezindaweni zokuhlala zokuzamazama komhlaba nezimayini, futhi ingabekwa phansi emifuleni ngendlela yokucwila.4, Imelana nokugqwala kwamakhemikhali, ukugqwala kwangaphakathi, kwangaphandle kanye ne-microbial, ukumelana nokugqwala okuqinile nempilo.Ifanele ukudlulisa izinto ezine-asidi ne-alkaline, ukuthutha indle, igesi yemvelo, igesi nezinye izinto;5. Ukuguquguquka okuhle kwemvelo kanye nokumelana nesithwathwa.Ingasetshenziselwa amapayipi okuhambisa amanzi angaphakathi nangaphandle.6. Impilo ende yesevisi, nempilo yesevisi engaphezu kweminyaka engama-50.7. Kulula ukuvuselela nokusebenzisa.
