1. Ubunzima obulula, uthutho olufanelekileyo, ulwakhiwo olulula:umbhobho wentsimbi owenziwe ngamazimba unamandla okwakha aqinileyo, kaninzi ufuna izixhobo zokwakha ezincedisayo ezifana neekhreyini;Ubuninzi bombhobho wokuhambisa amanzi we-PE bungaphantsi kwe-1/8 yombhobho wensimbi, ubuninzi be-0.935g /㎝3 umbhobho wentsimbi yi-7.88g /㎝I-3, amandla okwakha aphantsi, kwaye inkqubela phambili yokwakha ikhawuleza.

2.Ukumelana nokubola: Emva kokusetyenziswa kwexeshana lombhobho wensimbi, i-zinc layer itshatyalaliswa nje, okubangela ukubola kombhobho wensimbi.Ubomi benkonzo yombhobho wensimbi ye-galvanized malunga ne-10 iminyaka.Umbhobho wonikezelo lwamanzi we-PE unozinzo oluhle lweekhemikhali kunye nokumelana nokugqwesa okugqwesileyo.Ukwabelana ngesondo, okungaphenduliyo ngamachiza kunye nezinye izinto emanzini, kunobomi benkonzo ukuya kwiminyaka engama-50.

3.Euqhagamshelo olulula, ufakelo olulula:umbhobho wentsimbi ekhandiweyo akufanele udityaniswe.Xa i-welding ye-flange kufuneka idibaniswe kwindawo enye yokudibanisa, i-galvanized layer yonakaliswe yi-welding kufuneka iphathwe ngokukhuselwa kwe-corrosion;Umbhobho wonikezelo lwamanzi we-PE wamkela uqhagamshelo olunyibilikayo olushushu.Kuyafaneleka kwaye ngokukhawuleza, kunciphisa kakhulu ubunzima bokwakha, kunye nokunciphisa ngokudibeneyo ixesha lokwakha.

4. Ubomi benkonzo ende: ubomi benkonzo yombhobho wensimbi ephekiweyo malunga neminyaka engama-20-30 kuphela, ngelixa umbhobho we-PE unokumelana nokukhukuliseka kweendaba ezahlukeneyo zeekhemikhali, kunye nobomi benkonzo ukuya kwiminyaka engama-50 phantsi kweemeko eziqhelekileyo zokusebenza, ezihambelana nesakhiwo sethu samanje. imithetho yobomi.

5.IUdonga lwangaphakathi lugudile, isivuno samanzi sikhulu, kwaye ukusetyenziswa kwamandla kuncinci:uburhabaxa n ixabiso PE ityhubhu kuphela 0.008.Ubunzima bombhobho omtsha we-galvanized steel 0.025, kwaye ixabiso le-roughness liya kunyuka ngamaxesha angama-510 emva kweminyaka engama-20 yokusebenza.Ukunikezelwa kwamanzi e-PE ngenxa yokuba umbhobho awudli, ngoko uburhabaxa bayo abutshintshi ngokuhamba kwexesha.Ngaphantsi kombhobho ofanayo kunye noxinzelelo olufanayo lwamanzi, ilahleko yokuchasana endleleni ingancitshiswa ngama-30%.Umthamo wokuhambisa amanzi ungcono kakhulu kunombhobho wentsimbi, kwaye unokuhlala iminyaka engama-50.Akukho zinguqu zinkulu.

6. Ukugcinwa lula kunye nokugcinwa okuphantsi cost: izixhobo zepayipi ze-PE ezinobukhulu obukhulu zilula ukulungiswa, zinokulungiswa kwaye zifakwe ngaphandle kokuphazamiseka kwamanzi, kwaye azidingi izinto ezibizayo kunye nezingcolileyo.Ngokwamava okwenene kwezobunjineli, iindleko zokugcinwa kweepayipi ze-PE zi-30% kuphela zombhobho wensimbi.

7. Ukumelana nokunxiba kakuhle: Ukumelana nokunxiba kombhobho wamanzi we-PE kungaphezulu kwamaxesha ama-4 kumbhobho wensimbi.

8.Ukumelana kakuhle nobushushu obuphantsi: iqondo lobushushu eliphantsi lobushushu bombhobho wonikezelo lwamanzi we-PE liphantsi kakhulu, kwaye linokusetyenziswa ngokukhuselekileyo kwiqondo lobushushu le- -20-40 ° C. Ngexesha lokwakhiwa kwebusika, ukunyanzeliswa kombhobho akuyi kwenzeka ngenxa yokumelana nempembelelo efanelekileyo yezinto.

9.Gukuxhathisa ood kunye bhetyebhetye: ukwakhiwa kombhobho wensimbi ene-galvanized ineemfuno eziphezulu zesiseko sombhobho kunye nokulungelelanisa;Umbhobho we-PE ngumbhobho onamandla aphezulu, ukunyuswa kwawo ngexesha lekhefu kungaphezu kwama-500%, okunokukhokelela ekuhlalweni kwesiseko esingalinganiyo kunye nokuchithwa.Iguquguquka kakhulu.Ukuguquguquka kweminye imibhobho ye-PE ivumela i-P enkulu yokufakelwa kombhobho we-pe ubukhulu ukuba ibhijelwe, ngakumbi ukufakwa kombhobho we-pe ubukhulu obuncinci, okunciphisa iindawo ezininzi zokufumana.Ngethuba lenkqubo yokwakha, imiqobo inokugqithwa ngaphakathi kwendawo ye-zigzag yesikali esivumelekileyo sombhobho ukunciphisa ubunzima bokwakha.

10.Ukuxinana kakuhle komoya: Ubungakanani obukhulu be-pe pipe fittings zidibaniswe yi-melt eshushu, eyona nto iqinisekisa ubunikazi besakhiwo sezinto ezibonakalayo kunye nomzimba wombhobho ngokwawo, kwaye ugqiba ukuhlanganiswa kokudibanisa kunye nombhobho.
