Pipe ea tšepe ea centrifugally cast ductile e entsoe ka tšepe e chitja ea graphite ka centrifugal spinning process.The liphaephe, tse ka fetisang litaba tse ngata tsa mokelikeli joalo ka metsi, oli le khase, li sebelisoa haholo mererong e fapaneng ea liphaephe bakeng sa metallurgy, morafo, polokelo ea metsi, peterole. le ts'ebeliso ea litšebeletso tsa sechaba litoropong.
1.Ho ba le matla a phahameng, ho tiea ho hotle joalo ka tšepe le ho hanyetsa kutu ho feta tšepe, e ka ba thusang ho mamella ts'oenyeho e bang teng nakong ea lipalangoang, ho kenya, ho sebetsana le tšebeliso.
2.Pipe ea tšepe ea ductile ke sebaka se loketseng bakeng sa pipe ea tšepe e bohlooho le phala e tloaelehileng ea tšepe.
3.Liphaephe tsa DI li hlahisoa ka ho otloloha hantle, esita le botenya ba lebota, ho nepahala ha tekanyo e phahameng, ho qeta holimo ho boreleli le thepa e tsotehang ea mochine, hammoho le ho khomarela ka thata lera la ho roala ka hare le ka ntle.
4.Flexible Push-in joint and rubber gasket e sebelisoa e leng se etsang hore ho be bonolo ho kenya liphaephe.
5.Ke khetho e tšoarellang ho feta, kaha hangata e entsoe ka thepa e tsosolositsoeng, e leng ntlha e totobatsang pono ea tikoloho.
Li-diameter tsa 6.Inside li kholo ho feta tse ngata, phallo e ntseng e eketseha, e fokotsang tšebeliso ea matla le litšenyehelo tsa ho pompa ka nako
7.Ba na le matla a phahameng a ho phatloha, a loketseng likopo tse phahameng tsa khatello.
