Ipayipi le-iron ductile luhlobo lwepayipi yensimbi ekhonjiwe.Izidingo zekhwalithi zokulawula ibanga le-cast iron spheroidization grade 1-3 (izinga le-spheroidization “80%), ngakho-ke izakhiwo zemishini yento ngokwayo ithuthukiswe kangcono, ngemvelo yensimbi, ukusebenza kwensimbi.Ipayipi yensimbi ene-annealed ductile, isakhiwo sayo se-metallographic siyi-ferrite kanye nenani elincane le-pearlite, izakhiwo ezinhle zemishini, ukumelana nokugqwala okuhle kakhulu, i-ductility enhle, umphumela omuhle wokuvala uphawu, kulula ukuyifaka, ikakhulukazi esetshenziselwa ukunikezwa kwamanzi kamasipala, izimboni nezimayini, igesi, amafutha nokunye.
Inani elithile le-graphite eyindilinga lisatshalaliswa ku-matrix ye-ferrite ne-pearlite.Ngokwezidingo zobubanzi obujwayelekile kanye nokwelulwa, ingxenye ye-ferrite ne-pearlite ku-matrix ihlukile.Ingxenye ye-pearlite enobubanzi obuncane ngokuvamile ayidluli ku-20%, futhi ububanzi obukhulu ngokuvamile ilawulwa cishe ku-25%.
Inesimo sensimbi, ukusebenza kwensimbi, ukusebenza okuhle kakhulu kwe-anticorrosion, i-ductility enhle, umphumela omuhle wokuvala uphawu, kulula ukuyifaka, ikakhulukazi esetshenziselwa ukunikezwa kwamanzi kamasipala, izimboni nezimayini, igesi, uwoyela nokunye.Iwukhetho lokuqala lwepayipi lokuphakela amanzi, elinokusebenza kwezindleko eziphezulu.Uma kuqhathaniswa nepayipi le-PE, kusukela esikhathini sokufaka, ukufakwa kwepayipi ye-ink eyindilinga kulula futhi kuyashesha kunepayipi le-PE, futhi ingcindezi yangaphakathi nangaphandle ingcono ngemva kokufakwa;Kusukela endaweni yokubuka i-airtight kanye ne-anticorrosive, emva kokufakwa kwe-spherical inki tube tube airtight kungcono, kodwa futhi ngokusebenzisa izindlela ezihlukahlukene zokuqeda ukubola ukuze kuthuthukiswe ukumelana nokugqwala;Ngokusebenza kwe-hydraulic, ukucaciswa kwe-ink tube eyi-spheroidal ngokuvamile kubhekisela kububanzi bangaphakathi, futhi ukucaciswa kwe-PE tube ngokuvamile kubhekisela kububanzi obungaphandle, ngoba ngaphansi kokucaciswa okufanayo, ithubhu ye-inki eyi-spheroidal ingafinyelela ukugeleza okukhulu;Kusukela ekubukeni kwezindleko zokufaka nokunakekela okuphelele, ishubhu kayinki eyi-spheroidal inokusebenza kwezindleko eziphakeme kakhulu.I-inner wall spraying zinc, i-cement mortar anti-corrosion materials.
