Izinyo le-Super Carbide lokuhlola i-Oilfield
Ukusetyenziswa Ukwakheka kwamatye: Iibhithi zokubhola ze-oilfield roller cone zisetyenziswa kakhulu kwiintlobo ezahlukeneyo zezakhiwo zamatye, kubandakanya isanti, i-shale, i-mudstone, kunye namatye aqinileyo. Ukukhethwa kohlobo lwebhithi yokubhola ye-roller cone kuxhomekeke kubulukhuni kunye neempawu zokwakheka kwamatye. Iinjongo zokubhola: Iinjongo zokubhola zikwachaphazela ukukhethwa kweebhithi zokubhola ze-roller cone. Umzekelo, ukubhola imigodi yeoyile kunye nemigodi yegesi yendalo kunokufuna iintlobo ezahlukeneyo zeebhithi zokubhola ukuze kulungiselelwe...
