Cov Pob Zeb Mos Mos Drilling Roller Cone Bits IADC437 Sealed Bearing thiab Long TC Insert Bits
IADC437 tricone roller bits muaj cov tungsten carbide ntev heev uas haum rau kev khawb pob zeb mos heev.
Cov pob zeb mos mos yeej ib txwm muaj cov khoom sib xyaw nplaum uas npog cov hniav uas ua rau cov pob me me.
Cov tungsten carbide inserts luv dua tuaj yeem tho cov pob zeb tawv yooj yim, tab sis nws tsis tuaj yeem tho cov pob zeb mos thiab nplaum, kev sib tsoo me ntsis yuav tiv thaiv pob zeb kom tsis txhob tawg.
IADC437 yog TC ntxig ntev dua rau cov khoom siv dov lub khob hliav qab, nws tsim nyog rau kev khawb cov qauv mos ntawm qhov ceev ceev.
Cov Kev Ntsuas Ua Haujlwm:
Cov khoom siv dov lub khob hliav qab no yog siv rau cov qauv mos uas muaj lub zog qis thiab muaj peev xwm laum siab, xws li av nplaum, av nkos, chalk, gypsum, ntsev, limestone mos, thiab lwm yam.
