Kakaretso ea Pipe ea Tšepe ea Ductile
Liphaephe tsa Iron ke liphaephe tse entsoeng ka tšepe ea ductile. ductile iron ke spheroidized graphite cast iron. Boemo bo phahameng ba ho tšepahala ha tšepe ea ductile haholo-holo ka lebaka la matla a eona a phahameng, ho tšoarella, le tšusumetso le ho hanyetsa ho bola. Hangata lipeipi tsa tšepe li sebelisoa bakeng sa phepelo ea metsi a nooang le ho pompa li-slurries, likhoerekhoere le lik'hemik'hale tse sebetsang. Liphaephe tsena tsa tšepe ke ntshetsopele e tobileng ea lipeipi tsa tšepe tse entsoeng pejana tseo hona joale e seng e batla e li nkela sebaka. Boemo bo phahameng ba ho tšepahala ha liphaephe tsa tšepe tsa ductile ke ka lebaka la thepa ea eona e sa tšoaneng e phahameng. Liphaephe tsena ke lipeipi tse batloang ka ho fetisisa bakeng sa lisebelisoa tse 'maloa.

E sebelisoa haholo bakeng sa lits'ebetso tsa ho beha le tsa bushing indastering ea li-hydraulics.
V-3 (65-45-12) Ductile Iron, ASTM A536:
Sehlopha sena se na le matla a ho tsitsa a 65,000 PSI, matla a tlhahiso ea 45,000 PSI, ka bolelele ba 12%. Ho thatafala ho tloha 131-220 BHN. Sebopeho sa eona se setle sa ferritic se etsa hore V-3 e be mochine o bonolo ka ho fetisisa oa lihlopha tse tharo tsa tšepe tse etsang hore e be e 'ngoe ea litekanyetso tse phahameng tsa machiniability tsa lisebelisoa tse ling tsa tšepe; ka ho khetheha e kopantsoe le tšusumetso e nepahetseng, mokhathala, conductivity ea motlakase le thepa ea magnetic permeability. Ductile Iron, haholo lipeipi, e sebelisoa haholo-holo bakeng sa likhoele tsa metsi le likhoerekhoere. Tšepe ena e boetse e fumanoa hangata likarolong tsa likoloi le lits'ebetsong tsa indasteri.
V-4 (80-55-06) Ductile Iron, ASTM A536:
Sehlopha sena se na le matla a ho tsitsa a 80,000 PSI, matla a ho hlahisa 55,000 PSI le bolelele ba 6%. Ke matla a phahameng ka ho fetisisa a limaraka tse tharo, joalo ka ha a entsoe. Sehlopha sena se ka phekoloa ka mocheso ho isa ho 100,000 PSI matla a tensile. E na le tekanyo e tlase ea 10-15% ea machiniability ho feta V-3 ka lebaka la sebopeho sa eona sa pearlitic.
