Threaded txuas laum khoomtseem hu ua threaded txuas laum khoom, pob hniav laum khoom,
thiab kem hniav laum khoom.Threaded kev twb kev txuas laum ntsis yog ib hom pob zeb drilling cuab yeej uas yog
txuas nrog threaded laum pas nrig los ntawm cov xov ntawm lub laum me ntsis kom paub txog kev sib kis ntawm cov
cuam tshuam kev ua hauj lwm thiab rotating torque ntawm lub pob zeb laum kom tawg lub pob zeb.Qhov no hom pob zeb drilling cuab yeej
Cov khoom siv yog siv ua ke nrog hydraulic pob zeb drilling rigs thiab hydraulic pob zeb drilling rigs.
Cov ntaub ntawv tseem ceeb yog R22, R25, R28, R32, TR32, TR35, T35, T38, T45, T51, ST58, ST68,
EL60, EL68, T60 threaded laum lub taub hau khoom.Nws yog dav siv nyob rau hauv qhib-qhov mining, underground
mining, txoj kev tho txawv, anchoring engineering, moj tej tawg rauv hlau qhib, tunnel engineering,
hydropower engineering, quarrying thiab lwm yam kev tsim kho.
