I-API trione yokomba i-IADC127 4 5/8 intshi (118mm) iyathengiswa

I-API yentsimbi yezinyo i-tricone rock etywiniweyo i-drill bits kwisitokhwe esekwe kwelona xabiso liphantsi kunye nomgangatho ogqwesileyo ovela kumzi-mveliso waseTshayina
Inkcazo encinci:
I-IADC: I-127 -Ijenali yezinyo lentsimbi etywiniweyo kunye nokhuseleko lwegeyiji yolwakhiwo oluthambileyo olunamandla aphantsi oxinzelelo kunye nokuqhutywa okuphezulu.
Amandla acinezelayo:
0 - 35 MPA
0 - 5,000 PSI
Inkcazo yomhlaba:
Amatye athambileyo kakhulu, angacudiswanga, angadityaniswanga kakuhle afana nodongwe olungadityaniswanga kakuhle kunye namatye entlabathi, i-marl limestones, iityuwa, igypsum, kunye namalahle aqinileyo.
Singanikezela ngezinyo lokusila kunye ne-TCI trione drill bits kwiintlobo ezahlukeneyo zobukhulu (ukusuka kwi-3 7/8 "ukuya ku-26") kunye neeKhowudi ezininzi ze-IADC.

Ngokwemathiriyeli yokusika, iicones ezintathu zinokwahlulwa zibe yi-TCI bit kunye neMilled Tooth Bit
Amasuntswana e-Steel tooth trione anelinye igama eliyi-milled tooth tricone bit ekubeni amazinyo eveliswa ngumatshini wokusila, umphezulu wecone unobuso obunzima yitungsten carbide.
Izinyo eligayiweyo IADC127 lelokwakheka okuthambileyo kakhulu.Khetha amasuntswana okomba amatye afanelekileyo kubaluleke kakhulu phambi kokuba uqalise iprojekthi.
Ubunzima bamatye bunokuthi buthambile, buphakathi kwaye buqine okanye buqine kakhulu, ubunzima bolunye uhlobo lwamatye lunokuba luhluke kancinane, umzekelo, i-limestone, i-sandstone, i-shale ine-limestone ethambileyo, i-limestone ephakathi kunye ne-limestone enzima, i-sandstone ephakathi kunye ne-sandstone enzima , njl.
