Pipe ea tšepe ea ductile ke mofuta oa phala ea tšepe e entsoeng ka tšepe.Litlhokahalo tsa boleng ba taolo ea phaephe ea tšepe ea tšepe ea spheroidization bakeng sa 1-3 (sekhahla sa spheroidization "80%), ka hona, thepa ea mochini oa thepa ka boeona e ntlafalitsoe hamolemo, ka sebopeho sa tšepe, ts'ebetso ea tšepe.Annealed ductile tšepe pipe, sebopeho sa eona sa metallographic ke ferrite le palo e nyane ea pearlite, thepa e ntle ea mochini, ho hanyetsa kutu e ntle, ductility e ntle, phello e ntle ea ho tiisa, e bonolo ho e kenya, haholo-holo e sebelisetsoang likhoebo tsa masepala, tsa indasteri le tsa merafo, phepelo ea metsi, khase, oli joalo-joalo.
Palo e itseng ea graphite e chitja e ajoa holim'a matrix ea ferrite le pearlite.Ho ea ka litlhoko tsa bophara ba lebitso le bolelele, karolo ea ferrite le pearlite ka har'a matrix e fapane.Karolelano ea pearlite ka bophara bo nyane hangata ha e fete 20%, le hore bophara bo boholo hangata bo laoloa ke hoo e ka bang 25%.
E na le mofuta oa tšepe, ts'ebetso ea tšepe, ts'ebetso e ntle ea anticorrosion, ductility e ntle, phello e ntle ea ho tiisa, e bonolo ho e kenya, e sebelisoang haholo bakeng sa likhoebo tsa masepala, tsa indasteri le tsa merafo phepelo ea metsi, khase, oli joalo-joalo.Ke khetho ea pele ea phala ea phepelo ea metsi, e nang le ts'ebetso e phahameng ea litšenyehelo.Ha ho bapisoa le pipe ea PE, ho tloha nakong ea ho kenya, ho kenngoa ha pipe ea enke ea spherical ho bonolo ebile ho potlakile ho feta pipe ea PE, 'me khatello ea ka hare le ea ka ntle e molemo ka mor'a ho kenya;Ho tloha ponong airtight le anticorrosive, ka mor'a ho hlongoa spherical enke tube tube airtight molemo, empa hape ka mefuta e fapaneng ya anticorrosive bolela ho ntlafatsa ho hanyetsa kutu;Mabapi le ts'ebetso ea hydraulic, litlhaloso tsa tube ea enke ea spheroidal ka kakaretso e bua ka bophara bo ka hare, 'me litlhaloso tsa PE tube ka kakaretso li bua ka bophara ba ka ntle, hobane tlas'a litlhaloso tse tšoanang, tube ea enke ea spheroidal e ka finyella ho phalla ho hoholo;Ho latela pono e felletseng ea litjeho tsa ho kenya le ho hlokomela, tšupu ea enke ea spheroidal e na le ts'ebetso e phahameng ea litšenyehelo.Inner lebota fafatsa zinki, samente seretse anti-corrosion thepa.
