Umbhobho wentsimbi luhlobo lombhobho wentsimbi.Iimfuno zomgangatho we-cast iron iron pipe spheroidization grade control grade 1-3 (izinga le-spheroidization "80%), ngoko ke iimpawu zomatshini wezinto eziphathekayo ziphuculwe ngcono, kunye nobume bentsimbi, ukusebenza kwentsimbi.Umbhobho wentsimbi ene-anealed ductile, isakhiwo sayo se-metallographic yi-ferrite kunye nenani elincinci le-pearlite, iimpawu ezilungileyo zoomatshini, ukuxhathisa okugqwesileyo kokugqwala, i-ductility elungileyo, isiphumo esihle sokutywinwa, kulula ukuyifaka, ikakhulu esetyenziselwa unikezelo lwamanzi kamasipala, amashishini kunye nemigodi, igesi, ioli njalo njalo.
Umlinganiselo othile wegrafu engqukuva usasazwa kwi-ferrite kunye ne-pearlite matrix.Ngokweemfuno ze-diameter ye-nominal kunye ne-elongation, umlinganiselo we-ferrite kunye ne-pearlite kwi-matrix yahlukile.Umlinganiselo wepearlite kwidayamitha encinci awukho ngaphezulu kwe-20%, kwaye ubukhulu becala bulawulwa malunga ne-25%.
Inobume bentsimbi, ukusebenza kwentsimbi, ukusebenza kakuhle kwe-anticorrosion, i-ductility elungileyo, isiphumo esihle sokutywinwa, kulula ukuyifaka, isetyenziselwa ukubonelela ngamanzi kamasipala, amashishini kunye nemigodi, igesi, ioli kunye nokunye.Lukhetho lokuqala lombhobho wokubonelela ngamanzi, kunye nokusebenza kweendleko eziphezulu.Xa kuthelekiswa nombhobho we-PE, ukususela kwixesha lofakelo, ukufakwa kombhobho we-inki eyi-spherical kulula kwaye ngokukhawuleza kunombhobho we-PE, kwaye uxinzelelo lwangaphakathi nangaphandle lungcono emva kokufakwa;Ukusuka kwindawo yokubona umoya kunye ne-anticorrosive, emva kokufakelwa kwe-ink ye-inki ye-ink engqukuva ingcono, kodwa kwakhona ngeendlela ezahlukeneyo zokulwa nokutshabalalisa ukuphucula ukuxhathisa ukuhlwa;Ngokubhekiselele ekusebenzeni kwe-hydraulic, iinkcukacha zetyhubhu ye-ink ye-spheroidal ngokubanzi ibhekisela kwi-diameter yangaphakathi, kwaye inkcazo ye-tube ye-PE ngokubanzi ibhekisela kwi-diameter yangaphandle, kuba phantsi kweenkcazo ezifanayo, ityhubhu ye-ink ye-spheroidal inokufikelela kwi-runoff enkulu;Ukusuka kwindawo yokujonga iindleko zofakelo kunye nokugcinwa kweendleko, ityhubhu ye-inki e-spheroidal inomsebenzi weendleko eziphezulu.Udonga lwangaphakathi lokutshiza i-zinc, i-cement mortar anti-corrosion materials.
