Eminyakeni yamuva nje, ipayipi le-polyethylene seliyisinqumo esingcono kakhulu senethiwekhi yepayipi legesi yedolobha kanye nenethiwekhi yepayipi lokuphakela amanzi ngomfutho ophansi ngenxa ye-weld yayo eyingqayizivele futhi enhle ingaba lula ukuxhuma, ukumelana nokuqhekeka, ukuvikelwa kwemvelo, impilo, ukusetshenziswa kabusha nokunye. izici.Kanye nokuthandwa kwesicelo sepayipi yokucindezela kwe-PE, ukufakwa kwe-PE okuhlanganisiwe kokwakhiwa kwayo kulula, ukushisela okuthembekile futhi kuthola ukusetshenziswa okubanzi, ikakhulukazi insimu yegesi yedolobha ibidumile, nayo yaqala ukusetshenziswa kabanzi emkhakheni wokuhlinzekwa kwamanzi.Okuhlangenwe nakho komlando kubonisa ukuthi isicelo esiwusizo ekhaya nakwamanye amazwe nge-polyethylene yepayipi yesevisi yokuphila kwesilinganiso esiyisisekelo esilinganayo sokuxhumana esithembekile se-welding.Ngakho-ke, ukufakwa okuhlanganisiwe nomshini wokushisela kagesi usetshenziswa kabanzi futhi uthuthuka ngokushesha.Ngaphezu kwalokho, ipayipi lensimbi yensimbi yensimbi ye-skeleton polyethylene okuphakelayo okuhlanganisiwe eminyakeni yamuva nje, enezinzuzo zepayipi le-PE, futhi kube nokusebenza okuphezulu okubanzi kuneshubhu le-PE, ikakhulukazi ekuphikiseni ukuqhekeka kwe-crack stress, ukumelana nokukhasa, ukusebenza kwamandla okusebenza okuqhubekayo. ingcono kunaleyo yepayipi elihlanzekile le-PE njll, ngakho-ke, futhi yaqala ukusetshenziswa kabanzi kumapayipi amanzi kamasipala.Izindlela eziyinhloko zokuxhuma i-welding ye-fusion kagesi, ukufakwa okuhambisanayo okuhlanganisiwe kanye nomshini wokushisela kagesi uyathuthukiswa.

Isimiso esishiselwe ipayipi le-polyethylene

Isimiso esishiselwe ipayipi le-polyethylene elihlanganisiwe lishumekwe emshinini wokushisela kagesi odongeni lwangaphakathi lokushisa kwentambo yokumelana nepayipi ehlanganisiwe, amandla okushisa kuya kokufakwayo kanye nokuncibilika koxhumano lwamapayipi.Igebe emikhawulweni yomibili yeshubhu livaliwe, ukusebenzelana kwendawo encibilikayo kanye nokuncibilika ngaphansi kwengcindezi ezingeni lokushisa eliphezulu, ukuxubana kweketango lamangqamuzana, uma isixhumi esibonakalayo sifinyelela ekujuleni kokuhlangana kokugxambukela kweketango lamangqamuzana ubukhulu obudingekayo, isixhumi esibonakalayo sokupholisa semvelo. amandla e-welding adingekayo angatholakala, ukwakheka kwepayipi yokuxhuma i-solder enokwethenjelwa.Ngokusho kwesimiso sokushisela i-electrofusion kanye nokusebenza ekhaya nakwamanye amazwe kuqinisekisiwe, ipayipi lingakha ukuxhumana okuthembekile kwe-solder futhi ikakhulukazi ngokuklama kwepayipi elihlanganisiwe, izinga lokushisa lokumelana, izakhiwo zokumelana, ukufakwa okuhlanganisiwe kokufakwa kwamandla kagesi okuhlinzekwayo kanye nokuqina kwamapayipi kanye nemvelo yezinto. isimo sangaphambili sokuxhuma isixhumi esibonakalayo, esixhunywe kusixhumi esibonakalayo phakathi kobubanzi be-slit nokufana, okokufakwayo kanye ne-tubing clamp ekuzinzeni nesimo, imingcele yokushisela, izinga lokushisa elizungezile, izinga lomqhubi nezinye izici.
