Borehole steel kav yog tshwj xeeb siab - lub zog steel kav hlau nrog 3 hli lossis ntau dua, tsim rau cov haujlwm Borehole kev tshawb nrhiav haujlwm. Nyob ntawm seb cov chaw ib puag ncig ntawm ntug kev thiab cov txheej txheem, phab ntsa thicknesses feem ntau ntawm 6 hli thiab 12mm.
Tus qauv txheem torque ntau ntau rau tho kav yog 7,000-8,000 Newton Meters (NM). Txawm li cas los xij, nyob rau hauv kev ua haujlwm drilling tiag tiag, lub zog torque yuav raug hloov kho raws li geological hom, thiab drilling Rig kev ua haujlwm kom muaj kev nyab xeeb thiab ua haujlwm.
