cov ntsiab lus
Tricone ntsis yog muab faib ua ob hom: ib qho yog cov hniav me ntsis, thiab lwm qhov yog khawm ntsis. Qhov kev faib tawm no yog raws li IADC code.Yog li IADC code yog dab tsi?
IADC code siv:
Thawj tus lej:
1,2,3 yog hais txog cov hniav hlau
4,5,6,7,8 hais txog tungsten carbide inserts me ntsis
Tus lej thib ob:
1 hais txog cov pob zeb mos;
2 hais txog cov pob zeb mos mus rau nruab nrab nyuaj;
3 hais txog nruab nrab hard pob zeb txheej;
4 yog hais txog txheej pob zeb nyuaj.
Tus lej thib peb:
1 yog hais txog tus qauv qhib cov kabmob cov menyuam me
2 hais txog huab cua bearing menyuam ntsis;
3,4,5 yog hais txog kev kaw cov kabmob cov menyuam me;
6,7 yog hais txog phau ntawv xov xwm kabmob cov menyuam me.
Xws li IADC 537. Nws yog hais txog tungsten carbide ntxig tricone me ntsis nrog cov phau ntawv xov xwm bearing cov menyuam me, thiab nws haum rau laum nruab nrab hard pob zeb txheej.
