Ukusetshenziswa kwe-PE Pipe

1. Ipayipi lezimayini le-PE
Phakathi kwawo wonke amapulasitiki obunjiniyela, i-HDPE inokumelana okuphezulu kakhulu nokugqokwa futhi ibonakala kakhulu.Uma ukuphakama kwesisindo sengqamuzana, izinto ezibonakalayo ziyakwazi ukumelana kakhulu, zize zeqe izinto eziningi zensimbi (njenge-carbon steel, insimbi engagqwali, ithusi, njll.).Ngaphansi kwezimo zokugqwala okuqinile nokugqoka okuphezulu, impilo yesevisi iphindwe izikhathi ezingu-4-6 kunepayipi lensimbi kanye nezikhathi ezingu-9 ze-polyethylene evamile;Futhi ukusebenza kahle kokudlulisa kuthuthukiswa ngo-20%.Izakhiwo ezivimbela ilangabi kanye ne-antistatic zinhle futhi zihlangabezana nezidingo ezijwayelekile.Impilo yesevisi ye-downhole ingaphezu kweminyaka engu-20, inezinzuzo eziphawulekayo zezomnotho, ukumelana nomthelela, ukumelana nokugqoka kanye nokumelana kabili.

2. Ipayipi le-PE indle
Ipayipi le-PE lokulahla indle libuye libizwe ngokuthi ipayipi le-polyethylene ephezulu, okusho ukuthi i-HDPE ngesiNgisi.Lolu hlobo lwamapayipi luvame ukusetshenziswa njengokukhethwa kokuqala kobunjiniyela bakamasipala, ikakhulukazi embonini yokuhlanza indle.Ngenxa yokumelana nokugqokwa kwayo, ukumelana ne-asidi, ukumelana nokugqwala, ukumelana nokushisa okuphezulu, ukumelana nomfutho ophakeme nezinye izici, kancane kancane kwashintsha indawo yamapayipi endabuko njengamapayipi ensimbi namapayipi usimende emakethe, ikakhulukazi ngoba leli payipi linesisindo esincane. futhi kulula ukuyifaka nokuhambisa, futhi ukukhetha kokuqala kwezinto ezintsha.Abasebenzisi kufanele banake ngokukhethekile amaphuzu alandelayo lapho bekhetha amapayipi enziwe ngale ndaba: 1. Naka ngokukhethekile ukukhethwa kwezinto zokusetshenziswa zamapayipi epulasitiki.Kunezinkulungwane zamamaki ezinto zokusetshenziswa ze-polyethylene, futhi kukhona izinto zokusetshenziswa eziphansi njengama-yuan ayizinkulungwane ezimbalwa ngethani ngalinye emakethe.Imikhiqizo ekhiqizwe yile nto eluhlaza ayikwazi ukwakhiwa, ngaphandle kwalokho, ukulahlekelwa kokusebenza kabusha kuzoba kukhulu.2. Ukukhethwa kwabakhiqizi bamapayipi kuzoncika kubakhiqizi abasemthethweni nabaqeqeshiwe.3. Uma ukhetha ukuthenga amapayipi e-PE, hlola abakhiqizi ngaso leso sikhathi ukuze ubone ukuthi banawo yini amandla okukhiqiza.

3. Ipayipi lamanzi le-PE
Amapayipi e-PE okulethwa kwamanzi ayimikhiqizo yokushintshwa kwamapayipi ensimbi endabuko kanye namapayipi amanzi okuphuza e-PVC.
Ipayipi lokuhambisa amanzi kufanele lithwale ingcindezi ethile, futhi i-PE resin enesisindo samangqamuzana aphezulu kanye nezakhiwo ezinhle zemishini, njenge-HDPE resin, ngokuvamile iyakhethwa.I-LDPE resin inamandla aphansi aqinile, ukumelana nokucindezela okubi, ukuqina okubuthakathaka, ukuzinza okungalungile kwe-dimensional ngesikhathi sokubunjwa nokuxhumeka okunzima, ngakho-ke ayifaneleki njengempahla yepayipi lokucindezela kwamanzi.Kodwa-ke, ngenxa yenkomba yayo ephezulu yokuhlanzeka, i-PE, ikakhulukazi i-HDPE resin, isibe yinto evamile yokukhiqiza amapayipi amanzi okuphuza.I-HDPE resin ine-viscosity encibilikisiwe ephansi, i-fluidity enhle nokucubungula okulula, ngakho-ke inkomba yayo yokuncibilika inezinketho eziningi, ngokuvamile i-MI iphakathi kuka-0.3-3g/10min.
