IADC127 12 1/4 Milled Tooth Roller Cone Bits yokwakha ama-HDD Rock Reamers
Incazelo Yomkhiqizo
I-Milled Tooth Roller Cone Bit yenzelwe kuphela ukubhoboza amatshe athambile noma amatshe odaka ahlanganiswe nokwakheka okunamathelayo, ama-TCI (tungsten carbide inserts) ama-tricone bits awakwazi ukubhoboza ukwakheka okuthambile kakhulu ngenxa yesilinganiso sokungena esihamba kancane (ROP) kanye ne-bit-balling.
Ama-roller cone bits amazinyo aqoshiwe asetshenziswa kakhulu ekunqamuleni i-HDD edwaleni lodaka futhi ahlanganiswe ngokuqinile ukuze i-barrel reamer ingakwazi ukudlula kuwo futhi i-TCI rock reamer ilula kakhulu ukuyi-bit-balling.
