I-API trione drill bits intengo IADC216 4 5/8 amayintshi (118mm)
Incazelo Yomkhiqizo
4 5/8" I-TCI trione bit isetshenziswa kakhulu ekubhobolweni kwemithombo yamanzi, ukuhlola, imbobo yokushayela ye-HDD, ukunqwabelanisa isisekelo, inomklamo ophakathi nendawo we-jet hole, ngakho-ke iyasebenza futhi ekubholeni ukujikeleza okubuyela emuva.
I-bearing ivaliwe, impilo yokusebenza yinde kakhulu kunezingcezu zamarola ezithwele.
Lolu hlobo lwamazinyo ensimbi i-tricone bit lunembobo emaphakathi efanele ukubhoboza i-RC (Reverse Circulation drilling).
I-IADC216 trione bit ingabhoboza ukwakheka okuqinile kune-IADC126, ukukhetha i-IADC efanele ngokokuqina kwamadwala kuyisinyathelo sokuqala sokubhola okuseqophelweni eliphezulu. I-Far Eastern Drilling iyimboni eqinisekisiwe ye-API ye-tricone roller bit.
